“The oil they use in the beginning is so pure” lol

For anyone that’s thinking “oh hey I don’t have to change my oil for a year” please do not forget to check your oil level between intervals

The manufacturer does NOT have your best interest in mind. They just want it to last to the end of the warranty period. Extended oil changes and lifetime transmission fluids were all about lowering the "cost of ownership" I had a 2004 Toyota Camry and was following the maintenance schedule. Then at the 90,000 mile service, some services like transmission fluid change were now check fluid. When I questioned the change, they said to lower the "cost of ownership." Probably because Toyota's appeared expensive to maintain. Manufacturers really don't want you to keep your car 300,000 miles. They need to sell you a new car. 😅

GM always said to wait for the oil light to come. I waited like it says and it never came on until 11k miles each time and then, I immediately got the oil changed. Come to find out, it ruined the timing chain on my Chevrolet Cruze because the oil needed to be changed more often. Cost me $2790! What is cheaper, an oil change every 5,000 miles or $2790 for a timing change? You do the math! Waiting that long always gummed up the engine! I’ll stick to every 5,000 miles!

It also depends on the type of driving you mostly doing. If it’s mostly short journeys there’s more cold starts than mostly long journeys so the oil will degrade quicker.

For everyone who thinks that oil lasts 20k miles or once a year needs to remember - oil is cheap, engines are not

What the owners manual also states is that the oil change intervals is based on ideal driving conditions.

Extended oil change intervals are due to government regulations imposed on new car manufactures and are driven by the environmental concerns and not the wear concerns. So, of course the owner's manual will reflect that. The new car dealerships are branded independent businesses and can recommend what they feel is best for the engine.

I change my own engine oil - fraction of the price. It's really not hard folks.

Depends on how the car is driven. Can be anywhere from 3,000-10,000 miles. Stop n go delivery cars change at 3,000 miles, whereas everyday highway driving cars change at 10,000 miles. Also depends on which kinda oil and filter.

2:42, "the oil they use at the beginning is so pure." Lmao. You should be fired sir.

You can tell a difference in performance and fuel use when you change the oil. Huge difference. I’m a self employed truck driver and I can tell a difference on my rig. And using the right oil on your vehicle matters

I have never seen an engine have a catastrophic failure because the car’s owner overcharged the oil. The opposite in not true. Change your oil based on mileage not time.

The manufacturer only warranties the powertrain for 60,000 miles. Following the oil life monitor will ensure the powertrain at least makes it this far. I could not say how many engines I've seen have an internal lubricated part failure at about 100k. When quizzing the customer about oil changes, "when the car told me to". Keep your oil clean it's less expensive than a new engine.

There is NOTHING wrong with changing oil more often than needed. Clean, fresh oil will always help protect against wear better than filthy, carbon laden oil.

I am a bit old school when I went synthetic I went all the way up to 4000 miles. I know it cost me quite a bit over the life of the vehicle and I am good with that. Currently I have a small local mechanic doing the work. If he finds something wrong we fix it. The chain establishment I went to before had a lot of recommendations for service. You kind of had to sort through them. My hemi engine has small oil galleries and is known for burning out lifter rollers and eating cans. $1500 over the life of my truck seems cheap.

Oil is cheap. Engine costs a ton. The choice is yours. Quoted from scotty kilmer

For me it just feels good to change my own oil! I know it was done right at a reasonable price. I use the oil and filter that I want to use. If I use any shady tactics, I'm only cheating myself. There's no driving away from the oil change wondering if they REALLY changed your oil or just charged you for it. I've always changed it based on the what the car manual says with no problems.

It's not an "oil change monitoring system". There's no sensor measuring the oil. It's just the computer calculating when it should be changed.

The oil change recommendation from the manufacturer is their best engineered estimate when they design and build that particular engine. After some time, inherent issues with particular engines sometimes become apparent to dealers and mechanics. My 2014 Ford 5.4 Liter Triton V8 engine is now known to have a number of issues related to oil condition. The engine is known to have excellent longevity if oil is changed more frequently than recommended. It's also known to destroy itself if oil changes are pushed beyond the manufacturer's recommended change period.

Don’t trust a mechanic that drives a dodge nitro

it depends on the driving environment too. if you live in a hot & dusty place w/ continuous stop and go traffic day in and day out (like i do), then you need to replace your oil more frequently.

I owned a 1972 442 with a 455 that had dual exhausts and the W-31 camshaft. I changed the oil every 3 months. I ran it from 1971 to 2000. It eventually actually fell apart because of rust, But the engine was running just as good at that point as the day I got it.

As a mechanic, all I can say is.. IT DEPENDS. If you do alot of extended highway driving you can go longer on oil changes(no more than 10000 miles) If you short trip or do alot of in town driving then definitely change sooner(3000 miles). You also have to keep in mind the quality of the oil filter which is just as important if not MORE important than the oil. Oil is tightly regulated and tested and most oils perform really well, filters not so much .Do not put quality oil in your car with a cheap filter. Filter quality roughly matches price so its difficult to go wrong. The goal is to change the oil when it reaches below an optimum performance level. Better to change sooner than later. Why risk pushing the oil past its limit?

the oil they use in the beginning is so pure , lol

When u're NOT from Canada but still watch because they're more informative than where u live...

Very interesting. However, something about swapping out the black oil for amber oil makes me feel good inside even though my vehicle is low mileage. I do it myself so it's not a big expense. Keep up the great work!

… I grew-up with the 3-months/3000-miles change intervals, and it’s taken me awhile to “believe”in the new intervals … it’s absolutely true that I’m not driving my dad’s car with his oil in it any more - engines and motor oils have both improved tremendously … but I can tell you that it’s all I can do to prolong oil changes in my Hondas out to 6 months/7500 miles ! Even though my yearly mileage has drastically reduced these last few years to around 8000 to 10000 miles, I start losing sleep after I pass the 4-month/4000-miles mark ! … my wife says I need therapy … 🙄😖🤣👍

The oil in the beginning is so pure. Lol.

If you spend an excessive amount of time idling (especially with a cold engine) or drive a lot of short trips without hitting full engine temperature you should definitely change the oil more frequently.

I change my own oil every 3000-3500 miles regardless of what the manual says and ALWAYS get a sample of the oil and always comes back fine.

Always loved Market Place Thanks for your great work to help the average guy

Follow your owners manual and if you use your car in traffic or dusty roads follow the "severe duty" or "severe conditions" oil change interval.

I check the oil everytime I gas up and learned how to do my own oil change.

i was surprised to see so many older cars at the gas station. good to see people actually using things longer for once

I recently took my Honda CR-V into the dealership for an oil change. They looked and told me I was wasting my money, and to go at least another 2,000 miles before I had it changed. I did. The service writer took the time to reassure me that changing every 5,000 miles was unnecessary. That's why I get stuff done there.

Sorry but having owned or leased at least 30 vehicles over 45 years I still say changing oil is one of the most single beneficial things you can do to your vehicle no matter what the owners manual says. Maybe since I do it myself it makes it easy and much cheaper than taking it in to the shop. They quote $100 to change oil ?? I do it for $20 with filter and good quality oil. I still change oil and filter around 6-7 thousand miles. Years ago I used to change it every 3000 as suggested. My oldest car is a 1992 Honda Prelude.

I change the oil in my tesla every 3 months....runs great!

If you are driving anything with variable timing you should change it every 3000 miles. The manufacturer recommendation is to get it out of the warranty period and to keep the advertised annual cost of ownership low. All three of the domestic manufacturers have gone through this issue with their variable timing engines. Massive expensive repairs to engines just out of warranty, but well short of their expected life. Same issue with their lifetime transmission fluid. It gets the car out of the warranty period, but gets very marginal after that.

This is rather funny! Being a heavy line tech for almost 30 years I’ve changed a LOT of engines in all makes and models …majority of the time due to longer than normal oil change intervals! As most engines get older and miles accumulate , the engines wear out slowly. I’ve always stated it’s better to change the oil sooner than later because you don’t want to wait till the oil is broken down to a point to cause excessive engine wear. Most engine wear happens on cold start up, when the oil is its thickest, as the oil breaks down it will tend to to gel up (sludge) and be difficult for the oil to flow to critical parts of the engine etc damaging engine parts. Even my own vehicles I’ve seen the affects of going extended periods without changing the oil…..oil consumption, engine rattles on start up and so on! Your not polluting the earth if you recycle the oil properly and your saving money by extending engine life! Every engine is different and driving habits can affect oil life. Short trips need more frequent oil changes vs highway driving ….a cold engine runs a little more rich with fuel than at operating temps …in which diluting the oil slowly…..contaminating the engine faster with shorter trips. Synthetic oils have helped extend oil change intervals cause they don’t tend to sludge but can still get very contaminated and cause engine damage with extended intervals. Imo it’s not worth the expense waiting to get that very last mile out of an oil change …..like the oil analysis expert said there’s no way to no how much more time on the oil they were testing. 5000 miles or 6 months is a good baseline to go by for the average person.

While I already knew this, I have always changed mine more often than needed. It saves problems in the long run and I often put 500,000 to 800,000 km on my engines before changing vehicals.

Just wanted to point out that manufacturers usually have a different oil change interval specified for those who drive under "severe" conditions. These recommendations are usually specified by miles/kilometers and should be followed regardless of what the oil life monitor tells you. Many more people's driving qualifies as "severe" driving than you'd think. If you idle a lot, drive in stop-and-go traffic, drive like a taxi (Uber / Lyft drivers), or sometimes even drive in dusty conditions, there's a possibility your driving qualifies as "severe" in your owner's manual. If your driving style comes anywhere close to being "severe," you'll want to use that schedule (especially if the car is under warranty) or at least shift your interval closer to it.

For my car, a 2017 Versa, they recommend changing the full synthetic oil every 5000 miles or six months, whichever comes first. I change mine between 5k and 6k miles, which is roughly 3 months, with my driving. I have a 35 minute commute to work.

My brother is a red sealed mechanic and has been working on vehicles for over 7 years straight to this point. He told me change the oil every 5000-6000km even if it’s synthetic. The filter stops working after 5000 even if the oil is still good for a bit the filter stops

I think it's more accurate to change the oil based on the quantity of fuel used, divided by the number of quarts/liters the crank case holds. When you've burned 200 times more fuel than the volume of oil in the crank case, that's when to change. The reason for this is, how the engine is used. If you're pulling a horse trailer up hills, the engine is doing much more work, burning more fuel, than if you're just cruising smooth and easy down a motorway. In the winter, the oil has much more of a tendency to condense water, than in the summer, just because it's cold. However, your fuel efficiency is much less, than in the summer, prompting more frequent oil changes, which, under those conditions is actually necessary! If you have a hybrid, which gets~21 Kilometers per liter(~50 MPG), because it holds ~4 liters of oil, you can actually go about 10,000 miles,(16,000 Kilometers) between changes. In winter conditions, or heavy in-town driving, the mileage is considerably less, putting the oil change interval closer to 10,000 Km(6,250 miles). the "Maintenance required" light comes on every 5,000 miles(8,000 Km). If the car is used for a taxi or other ride service, this is a very reasonable interval, but not a panic, if the light comes on while on a road trip. Just finish the trip, and change as soon as possible, the engine will be fine. MAKE SURE YOU CHECK THE OIL LEVEL REGULARLY!!! The same holds true, for a four wheel drive truck, which with it's big-block V-8 engine, may only get 15 miles per gallon.(6.3 Km per liter). The crank case holds approximately 6 liters. That puts the oil change interval close to 7,560 Km.(4,725 miles). very reasonable for a heavy duty engine. If run hard, less distance between changes, more, if driven smooth and easy. no matter what, the thing contaminating the oil, is the quantity of fuel consumed by the engine, no matter what kind of engine it is, and it doesn't really matter how it's run, it will get the necessary maintenance, without spending too much on oil changes.

I change the oil myself, not for the car's benifit, but it gives me a warm, fuzzy feelings

The oil change intervals really depends on the type of engine. If you have a GDI engine (Direct Injection) you'll likely want to change the oil every 5000 miles or 6 months if you take frequent short trips in the car. Fuel dilution is a real issue in these engines and it can cause real problems long term. Fuel dilution is when you drive short trips frequently and the GDI engine doesn't warm up enough to burn off the excess fuel getting into the oil via blow by in the cylinders. When a GDI engine is cold, fuel seeps into the oil from blow by during combustion. Fuel in the oil can destroy the effectiveness of even the best Full Synthetic oil in a relatively short period of time. One way to help remedy this issue is to drive the car for more than 30-40 min to give the engine time to burn off the excess fuel in the motor oil.

Don't listen to the manufacturer, believe me, some tell you not to change you transmission fluid because it has life time fluid. What they mean is the transmission has a certain lifetime before its out. And let me tell you, most new cars are gdi and turbo or super charged. So changing your engine oil every 5-7 k km is a good idea if you want your car to last. Advice comes from a mechanic, and remember engine oil is cheaper the a modern engine or an engine rebuild.

After driving 6000km my oil is already dark, and I usually change it, can't imagine driving up to 16,000km on the same oil.. And I use high mileage full synthetic oil. 202,000km on my 2007 Lexus IS250 AWD, still running strong.

You can look at it either way. The mechanics want you to come into the shop more often so they will tell you to change the oil more often. The car companies on the side of selling more cars are going to want you to drive as long as possible so you ruin your engine and need a new car sooner. Also, I'm sure car companies get incentives for being more "environmentally friendly" by using oil more efficiently. Are they actually making the engines more efficient or just stretching the length of time that they recommend oil changes?

I love this show. I've learned so much from it. well done Marketplace.

as a general rule I never go over 5,000 miles on my oil changes. modern oils today yes they can go up to a year or up to 20,000 miles whichever comes first but I can tell you from first hand experience I've seen the inside of engines that have had these extended OCIs they're usually caked with sludge and varnish and are very dark on the inside. Engines that have their oil changed more frequently are very clean on the inside and these extended oil change intervals are a big reason why most modern vehicles the engines usually can't go over 150,000 miles before they need major repair. things you need to consider when you do extended oil changes is over time your motor oil gets contaminated with fuel and over time it gets contaminated with moisture from condensation. these two things lower the engine oils total Base number and over time it can make your oil become acidic and it can lose its ability to lubricate your engine. a new engine is roughly $10,000 versus between 60 to $100 every 3 to 5 months for an oil change which one is worth it to you?

I would think oil changes would partly depend on how harsh the driving conditions are. Also there's different types of oil.

5,000 miles with full synthetic oil and a QUALITY oil filter (Mobil 1, etc) Don’t forget to change transmission fluid and coolant. Trans fluid every 30,000 miles or so, coolant every 50,000

I do it every 4 months regardless their milage. 187k miles later and the engine revs as smooth as the day I got it

The real problem is that many people dont check oil levels between services.

the owner's manual is designed to get you out of warranty and have your vehicle blow up so you purchase a new one. so changing your oil once a year every 16,000 with conventional will get you to 160000 but after that your engines extremely worn out.but now it's in the best interest of the manufacturer of your vehicles going and you're looking at them to buy a new one.

Also depends on whether it's mineral, semi or full synthetic.

This is for Normal maintenance schedule, the owner's manual also has a section for special circumstances which states that it should be about every 6 months ... one of those special circumstances could be you only use your car on very short trips less than 8KM or you're often in stop/go situations.

I change my own oil every 3,000 miles in my wife’s Impreza and my WRX. It takes me about 1/2 an hour. It’s well worth it, especially with a turbo.

Every 3000-5000 miles. Oil is cheap. Filters are cheap. Engines are not cheap. Do not use FRAM filters!

Best thing to do is learn to change it yourself.

Thank you for this video. It's an eye opener.

I have access to factory oil. It’s so pure that I confidently change it every 10 years!

Or just do it yourself and save a ton

I wouldn't believe either one. Manufacturers don't want you driving the same vehicle for a decade and dealerships give false information to see you more often to sell you more crap plus make a little on the frequent oil changes. I would change it every 5-6k miles. Oil filters even the great ones I can't imagine how effective they can be for that long. Especially your oil.

With the new ILSAC GF-6A certification oils on the shelves, synthetic oils are 25% better than before and can definitely be used longer. Just ask your dealership if they're still using IL GF-5.

Consider idling time if for some reason you need to do this or if your vehicle does not consider idling time... good program. Thank you for making it. Learn alot, cheers. Maurice :)

Remember your warranty only lasts so long and once that time has elapsed you're on your own

In my opinion, i think oil change requires depend on how often or far distance you drive your vehicle daily.

Depends on the type of oil you use synthetic you can go longer then conventional oil. Conventional oil starts to break down after a certain mile and a certain period of time. Just like fuel in your cars fuel tank starts to go bad and break down the longer it sits there.

I change my oil every 6 months which is roughly every 3000 miles. Probably too often but I do it myself, it's easy, and I plan to keep the car a long time. Hoping it will outlive me 😃

Mechanic here. It depends on the oil that's used conventional is good for 6k-8k(kms) or 6 months and synthetic can be 10k-24k(kms) or 1 year. Oil filter also must be taken into account as cheap filters are only rated for 8k while premium filters can go up to 24k When a customer wants synthetic put in but only wants a cheap filter I go by the weakest link and make it as 8k-10k.

Synthetic oil can last a very long time. The 3k mile rule was when older vehicles used conventional. Dealers and shops are all about money and they will always recommend an oil change. Buy a tool set and do the oil changes yourself every 4-7k miles.

For me, checking dip stick level and oil quality is crucial.

100% Agree. Thank you for the info. This a contentious issue with some people. Always follow the Manufacturers Manual 🚗

I do mine every 3,000 miles. Dont care what anyone says. I use the "high mileage" variation of whatever brand is on sale. Usually Quaker State, Supertech or Penzoil. Fram or Purolator filters.

This oil argument is like asking.....should I bath once or twice a day? Or none at all? Lol.

Depends on the vehicle and the city driving. Subarus for example have a history of disappearing oil so you should check your dipstick levels often. We had a reliable Subaru so we followed the owner's manual religiously. Years later at a gas station we kept finding the oil below the dipstick. Turns out the engine was burning oil and getting worse over time. If we had changed the oil more often the engine would not have gotten so bad.

lets not forget that the location, driving habit, to the quality and what oil you use depends on the interval.

Every car I have owned,changed the oil every 5000 kms. I have always got 350,000 kms plus out engines,good gas mileage for the life of engine,and no major break down. PLUS I DO THEM MYSELF FOR QUARTER THE PRICE

It makes sense to me that the manufacturer is going to tell you how to economically keep your engine running through the warranty period only. I like to keep cars for about double that. That said, I use full synthetic and change at 4000-5000 miles. My 2012 Toyota Sienna just passed 194,000, it has never had any engine work done, and it still shows almost no change on the dipstick between changes. It would be interesting to know if others are getting this kind of engine life changing oil less often, or using conventional oil.

Thank You 😄 for all the information . It was very helpful. Ouestion , what is the best oil to buy. Also is the cheap oil good for your engine ? Thanks again. Stay Safe and God Bless.😘

Just check your oil dipstick to see the condition, when the oil looks dirty change it to prevent premature wear on your engine. There’s metal on metal contact and there will be metal particulate in the oil after some use which will hence cause more wear if you do not change it.

2004 wrx sti I change mine every month and a half(45 days) or 2000 miles MAX because I get on her hard regularly. Not to mention I'm always late to school so I gotta always speed. Plus it's always nice to get a quick UPDATE on what your car is looking like under the hood and on the underbody. PLUS I DO MY OWN OIL CHANGES . Filter and all.

I've been working as a mechanic for over 20 years and without question keeping your oil clean by changing it at least every 5000 miles will drastically extend the life of your engine and avoid all types of related problems that can occur from running dirty oil that can cost you thousands in repairs. I actually use some great car management software www.lonewolf-software.com/automotivewolf.htm to track the maintenance schedules on my own personal vehicles so I don;t forget myself to change the oil, filters and and inspect certain components periodically. Change your oil regularly and you will avoid needless problems.

Absolutely helpful! Thank you!

Cheaper to change engine oil & filter than engine repairs. Oil maybe good, but no mention of contamination from by products of combustion & engine wear.

"change oil once a year, the manufacturer knows best" -- warranties the car for 80k only.

Y’all really expected to get different advice between a Honda dealership and an Acura dealership? They’re the same manufacturer and company 🙄🙄

Thank U guys, you illuminated us somehow.

Changing oil more often than recommended will only make your engine last longer. It's like having a fesh oil all the time. No crud or deposit in the engine. Engine running smooth all year long. Oil is cheaper than a new engine. Original owner of 2002 Toyota Celica with 379k+ miles and runs like a clock.

I change my oil after every trip. Every day.

Thanks for the useful content. What about cars that are parked most of the time and used for short intervals. The Oil is recommended to change after 10,000KM but actually, this car makes this distance in about 2-3 years. Is there also a time interval after which the oil and other parts should be replaced no matter the mileage? What's recommended in that case for the Oil, filter, and other spare parts replacement?

The owner’s manual logic is to give you the cheapest maintenance cost for the duration of the warranty. The more often you change your oil the better for the longevity of the engine.

I have a GDI engine. I go by the owners manual severe usage interval, which is 3500 miles (5600km). I use 5w30 full synthetic oil. I change it myself. Costs me about $21 USD.

Here’s the plot twist: the manufacturers MAY have recommended longer intervals to... slowly run down parts that would need replacing and are sold by... them? I change my own oil and I’ve to say that even after half the recommended interval, the oil’s totally black and engine needs a lot of de-carbonning. I’d rather spend on oil than engine parts.

It's true that you should follow the car oil indicator (usually a Percentage left) to change oil. But also remember, if you use a low grade Oil filter (most mechanic shops use) and regular oil, versus say Mobil 1 or Purolator Oil Filter and Full Synthetic oil like Amsoil, it becomes a different story. I think even if you don't spend a lot on Extremely good Full Synthetic Oil, definitely spend top dollar on oil filters.

BMW - and Audi - are sometimes criticized by diligent mechanics and owners for putting up 10,000 mils OCI. Many owners who care about their cars change it every 5k-6k.

Who the heck pays $100 for an oil change? You're getting ripped off
