They are only fuel efficient if you drive normally,NOT WHEN YOU DRIVE LIKE YOU'RE IN A NASCAR

Depends entirely on how you drive the car and, critically, how well you service/ maintain critical things, such as oil, coolant, etc.

Excellent video. Best explanation I’ve heard on turbos vs naturally aspirated. I have both and NOW i understand they have to be treated slightly different. Keep up the great work and I’ll keep watching. 👍🏼

The truth is, we pretty much are running out of naturally aspirated engines! Our options are very limited today.

Planned obsolescence and the fact they're sticking them into virtually every new car should answer that question in terms of long-term reliability.

Very nice 👍 Excellent description of use cases for turbo vs non-turbo. Also excellent description of how the engineers have to design the complexity of engines. Thanks, Mark!

Nice video. Appreciate the truthful information.

Excellent video. Going back a few years I remember my friends lusting after the Saab 9-3 Aero with the turbo 4-cylinder engine. I thought it was an amazing design at the time, but I was living in a hot, desert climate and it seemed their turbos preferred cooler climates. Now days I drive an E350 with the turbo inline 4 cylinder engine and am amazed at how much performance you can get out of a 2L.

Love your vids....lots of good stuff!

Very nice Excellent description of use cases for turbo vs non-turbo. Also excellent description of how the engineers have to design the complexity of engines. Thanks, Mark!

I just came across your video. Thank you so much. You made the video so easy to understand. I'm looking at the new 2024 Toyota Tacoma with 4 cylinder turbo. I feel a little bit more comfortable now.

After watching this video, I think going for the Lexus IS 350 F Sport sounds like a great idea. It looks fantastic and it's a NA V6. Thanks for the information and great videos as always. Keep up the good work. I was also deciding between BMW and Mercedes but decided Lexus might be the best bet. But, sometimes still kind of have trouble deciding.

I'm glad you decided to feature the J35 in the Accord. I own a 2003 Accord with the J30 engine. Hopefully I can buy the 9th gen Accord V6 one day. Fantastic 6 cylinder engines. Love this video.

Had a 1986 Ford Thunderbird with a little 2.3 turbo. I was just a kid old enough to drive. Worked my butt off to pay for it. I believe it was around 190 hp. which wasn't terrible for the 1980s. I fell in love with that car, had no intercooler. Not one thing while I owned it went wrong. I beat the hell out of it and towed a 19ft open fisherman style boat. I would be at the boat ramp ready to pull my boat out of the water. Always, mostly from the truck people would always keep an eye on it while I was pulling the boat out of the water. Like it wasn't going to do it. It had a five speed manual with a posi rear end. All you heard was the turbo spool up and it would easily pull my boat out, everytime. I put 120,000 rough miles on it before I sold it( had to so I could get a work truck). It wasn't the fastest car I ever had, but it was the best, most reliable and fun car I've ever owned. I'm an old man, I've had more cars then I can remember. Dam, I miss that car. I know turbos put extra wear on a engine, I couldn't kill that car. Had to be very lucky, because I ran it like it was stolen. Great car.

I have a 2017 Civic Hatchback with the 1.5 Turbo. I've been lucky so far to have had none of the problems associated with this engine. This car gets downright stupid real world MPG (34-37) and it's a blast to drive. BUT - I have no confidence that this will last for the long haul. Great Video Mark, one of my personal favorites.

Great work and informative. Back in 2008, I compared and opted to replace turbo with hybrid cars cause they both provide that extra boost, only with the electric, one gets instant torque, zero atmosphere impact, no added heat built up & amazing reliability with added low maintenance

The theory in practice is to take a small engine and add performance, which in turn provides for less emissions, and all the other ecological feel good legislation. Out of the equation is reliability, longevity. And the engine plastic melts like a candle, like Ford's disastrous Ecoboost engine, with enough heat to ignite the engine into flames. Carbon build up, integrity of oil quality. Personally, I like naturally aspirated engines, large displacement. Ford used to make a wonderful 460CID with a four barrel eight jet carburetor for their Lincoln line. Those were the days! I blame California for the demise of the auto industry.

My retired relative just bought a new Honda CRV with a non-turbo 4 cyl. The no turbo is why he went to it. He wanted less expensive complex technology and less parts and more reliability. It is also a top seller. His last car was a Fusion. My car is a 2006 Escape 4-cyl with 269,000 miles. The engine and auto trans have never been gone into. It does not burn oil.

I use to own a Peugot 508 turbo saloon and even after putting top grade Motul oil at service the turbo had issues like smoke and leaks later. Also, I saw the service history of the car and the turbo had repair work done to it a few years before.

Well explained. Thank you.

Simple and straight to the point

I always wanted to get an answer on this topic! Tyvm

🇨🇦 great subject & content. Have a great weekend 🇨🇦✌️👍

It's much more fun to drive turbocharged car. But as an owner I prefer reliability and simplicity of a regular engine.

After having a terrible charged car and now switching over to a regular 3.7 V6 I much prefer the naturally aspirated much less things to worry about and it sounds so damn good fuel economy for me has been about the same I average about 19 to 22 in the city with the V6 depending on how I drive and with the 4-cylinder turbocharged I would typically average about the same

good info. I like your channel.

I’m doing real world documentation on my 2018 Civic EXT, 1.5 liter, turbo, GDI, CVT. To date I have 124,100 trouble-free miles with exceptional maintenance. I’m hoping to get 300k miles without repair. Looking forward to your video on this type of engine.

You gave me the answer. Thank you!

I bought a 2021 Subaru Legacy with the 2.4 turbo. I like having the power when I want/need it, but I wish now I had bought the naturally aspirated 2.5 in the Legacy. Would have cost less and it probably would last longer. I make sure I change the oil a little sooner than Subaru recommends.

Wife has the V8 Mercedes 2 turbo. I ❤️ my golf. Never an issue. Great German build quality.

Very educative video

Appreciate your videos man!! Could you make one specifically for the Genesis G70 2.0 and 3.3 twin turbo?

Also, the newer Kia's and Hyundai's with the 1.6 L turbocharged four-cylinder GDI engine and the seven-speed dual-clutch transmission are unreliable as well. Please avoid any of them and buy the ones with the 2 L and/or 2.4 L four-cylinder non-GDI engine, if you are planning to purchase a Kia or a Hyundai. Better yet, buy the ones with the 3.3 L, 3.5 L and/or the 3.8 L V6 engines instead.

Mark, I found this video educational. Can you do one on superchargers. thanks

My daily driver was a golf tdi pd, with original factory turbo and re map 160bhp, 200,000 miles, change oil regular and air filter ( factory airbox). Also V.N.T never seized.

Listen carefully , turbos belong on diesel engines and racing applications . This guy all wrong about the false sales narrative "more power and better gas mileage" . It takes "X" number of joules (work energy) to move 3000 Lbs. from zero to 60 mph in 5 seconds . Force them and they blow the gas like a V8 . THERE IS NO FREE ENERGY . Gdi engine intake valves are shedding chunks of burned coked oil through the turbine side of the rotating element causing servere unrepairable damage . This debris then plugs the catalytic converters , very expensive . I am a turbine machinist for twenty years . I make a good living from the poor customers that fall for the B/S . ALWAYS get the bigger engine . If you gave me a free turbo car , I wouldn't thank you for it , and I couldn't sell it fast enough . Avoid GDI , turbo and CVT at all cost .

Yup, Now You're In My Territory. I Worked For Honeywell For 22yrs, In The Turbocharger Division. In Higher Altitudes They Lose Power Because Of Thinner Air. Another Problem Is, Bent Turbo Blades & Shafts From Turbo Heat. In1992, I Bought A Nissan 300zx, But, Not The Twin Turbo Version, And Still Have It Today ! The Only Difference Is Less Speed On The Front End, But Both Clock In At 155 mph. Love This Car !! 😉👌💯🏁

We have a 2001 Pontiac Grand Prix with turbo charger. On our trip to ND two years ago we averaged 35 mph. We never lacked for power over the high altitude passes or avoiding traffic with power when necessary. Our problem is the electronics controlling the defrost mechanism. We cannot find someone to fix it and often have to resort to manual means. I understand that many cars of our vintage are abandoned because they are not worth fixing. As the Electric Vehicles increases I can tell you that the circuits for control are subject to vibration, moisture and corrosion. Often total replacement is the only fix and the cost is more than the car is worth. Just like the battery pack on the Prius. The best car I ever owned the drove was a Cad Seville with the turbocharged V8. If I had a few beers after work and drove home 15 blocks on the back roads, the horn would start honking and the lights flashing. The problem was a sealed module mounted on the wall between the trunk and back seat. The drain from the moon roof was plugged creating a pond under the rear seat. I sold it for $300 bucks cash. I now have a 2001 Toyota Tacoma 2wd pickup without modules on the a/c , heat and wipers. I sort of miss elect windows, cruise and auto transmission but, it might be my last vehicle and I can trust it to get me home for dinner.

Kinda like AWD.(puts less stress on the engine, when drove lightly and not maxing it out,and not driving conservatively) Depends mainly on the engine and type of engine mainly.

Thanks......great explanation...........so choose what you want......many cars there..............

If you maintain your oil change on time turbo can be for life, fresh oil is the key to maintain the longevity of a turbo

Turbo 4s are generally short-lived. I had an Audi A4, and it was wretched in terms of reliability and upkeep. Used oil, lots of electronic issues, and at 50K miles, the turbo died. As naturally aspirated engines go away, we'll be driving more cars that are expensive, unreliable and so on. Gone are the days when your Toyota Camry would last 200K miles.

What about the honda accord 2.0t is it suppose to be reliable in the long run?

I'll take the Escape with the 2.5 4 cylinder, I DON'T WANT A TURBO. They are fast, but don't last

You also made a good argument for hybrid vehicles. Great for short trips, no turbo lag, less maintenance bc the engine only runs half the time, but good acceleration. The Honda CR-V hybrid is faster 0-60 than its 1.5 turbo sibling.

Useful clip as always .Do you think a 3 cylinder GDI turbo engine would last at least 200k if you generally drive below 3000 rpm and practice good driving habits you explained such as 1. not pushing the engine till its fully warmed up, 2. Idling the engine before shutdown. 3. Using a quality full synthetic oil and changing oil at 5k miles or 6 months. I love my little turbo but am paranoid about its long term durability.

Great video Mark, whats your take on a 2009 Porsche Turbo PDK, the last year of the highly successfully Metzger engine

In Fiat Ducato Vans with 2.3 liter diesel engines they suggest 48,000 km between the services! I made an oil service in my X3 20d 2008 recently, and after resetting the "calculator" it suggest 30,000 km to the next oil service!

The 2.0 tsi Is one of the most interesting engine by far

I have a 2016 1.5t civic 150,000 been a great car so far

Can you please do a reliability comparison with turbo versus supercharger?

Speaking of turbos, I saw a yellow 02 Z3 M roadster with appears to look like a huge 80MM turbo sticking out of its hood and it was just cruising by

What's the comparison between Turbocharging and Supercharging, as far as shopping for cars goes? And reliability. I know both technically reduce the lifespan of the engine, but I'd figure that Superchargers are a bit easier on the engine.

You scared me a lot. I drive a civic'18 in a tropical country. Should I be worried about oil dilution. I was told it affects in the extreme cold countries only.

That is why I got my new 4runner before too late. Just sold 2019 Accord 1.5 turbo. That sucks

Depends what your using them for, if your going like a teen with a lead foot, then its going to be bad on the engine. If you buy one to help you in times of need, say trying to go up a big bridge or hill, trying to pass someone, then your going to be OK. trying any of those with a small non turbo engine and its going to be scary.

Turbo is just an excuse to use a cheaper 4 cylinder or 6 cylinder engine rather than tried true bulletproof V8. By pushing these smaller liter engines, it pushes the engines well beyond there design limits. Hence why turbo cars often get less than 150,000 miles before detonation. Best to stick with electric hybrid car engines naturally aspirated without turbo, if you want power, fuel efficiency and longevity.

hello i have a question about turbo 4 cylinder engines . are they capable of long term reliability when only driven short distances ?

Yes it’s reliable, especially with Lexus NX 350 f sport (so I have it one) and also it single turbocharged 4 cylinder with 8 speed automatic transmission , and this is a major playing the game with Lexus 😁😁😁😁

Have the 2020 Honda Accord with the 1.5 turbo. Average 37.6 mpg.Rarely any short drives. Mostly highway. Oil changes when maintenance minder says oil has 40% life left...which is usually around 7000 miles. So far so good...knock wood.

It’s hard for me to get good mileage in my 2019 benz because I love the performance of the turbo coupled with the direct inject 4 cyl engine

We as a nation should demand the reduction of over-engineered vehicles. Why do we need plastic push buttons (that require chips) for starter, parking brake, transmission drive/reverse select , windows, seats, mirrors, etc? We got lazy. We should demand BASICS, QUALITY and SAFETY only AND an End to Dealerships, and an End of Turbo's. Gas Hybrids are still the only acceptable future mandate until hydrogen is perfected. PHEV and Electric are just stupid as the electrical grid cannot handle millions of them; plus, they will burn your garage/house down.

I've heard you speak poorly of the BMW 4.0 turbo. What are your thoughts on the AMG 4.0 V8 biturbo ?

I think that's all I needed to know. All in a short 10 minutes.

Hi Mark. I am planning to buy hybrid car. And not able to decide between kia sporatge hybrid SX prestige and honda CRV hybrid sports touring. Please throw some guidance.

I am looking to purchase a 2023 Toyota Sequoia or a 2023 Nissan Armada. I am concerned about the turbo engines. Is the Toyota 6 cylinder turbo in the NEW Sequoia a reliable engine or would a Nissan Armada be a better choice?

I don't own turbo charged cars, But if I did I would Change the oil NO less than every 5,000 miles with Amsoil Full Synthetic oil, Because I would drive it hard of course 🤓. I hear Honda has solved the oil dilution problem with better oil and some minor design changes, Don't know if that's true yet, I guess time will tell.

my mom had a 1986 Subaru XT Turbo in late 80s early 90s when me and my younger brother were kids she had the car for about 7.5 years fall 1985 to Spring 1993 until it was stolen from an auto repair shop and she bought a beater to replace it

Use decent full synthetic oil and give the engine a chance to warm before you hammer it. That's all you need to know.

Hence the importance of premium gas on those turbo charge engine.I have a 2020 turbo charge Audi only filling up with shell v-power.

Do some videos on the c43 amgs

What about Lexus N300 it’s got Turbo it seems like solid SUV & bullet proof engine!!! Regular maintenance 91oct your good 🤷‍♂️ Great Video Alan H

I don’t know anything about cars and this is just a thought, perhaps better engine cooling can help with the turbos? Idk.

Turbo lag is so 1980s the turbos today are either ran by the computer so there isn't much lag

Idk. All that heat turbos create, and a bunch of plastic parts under the hood doesn't make sense to me.

hows the 2018 c43amg?

So, if having a car with a turbo is a reliability, how concerning is it to have a car with a turbocharger and a supercharger. My Volvo 2020 V90 Inscription T6 estate has both. From the various Volvo owner forums I subscribe to I haven't noticed many complaints, but maybe my sample size is too small.

WHAT about a CORKSPORT RAM AIR INTAKE? I know they help the performance- but would that HURT one? Scotty Kilmer says NEVER run one.. THOUGHT?? or SUPERCHARGER???

I have been working on cars and come to realize most of turbo cars have so many issues after 100K miles. I'd rather have natural aspirated engine over turbo any day.

Would a larger engine (i.e. a 6 or 8-banger) tend to last longer with turbo than a 4-cyl. engine? In other words, can I lessen the risk of getting a turbo engine if the engine itself is larger? I'm good at regular maintenance and only drive hard for fun maybe once a month.

Good info., although the truth is, auto makers could care less about emissions. It's ALL about money. The only reason for emissions is because of government regulations.

great video

smart guy he is,,,,you need turbo on race cars,,,not to go work,,,

is it the same with smaller engines like comparing 1.6 and 1.4T? I'm thinking a smaller engine has a better chance to be more reliable than a bigger one with turbo since it wont make as much heat, no? 🧐

Turbos pump waaaaaay more adrenalin while you are wondering if this thing will ever get going, than after it goes.

What do you think about the Acura integra 1.5 turbo? Old Honda engine

I was looking to purchase the Honda CRV-LX or EX and had no idea about this turbo issue. Makes since. I am not sure if these 2024 Honda vehicles are properly put together. Can someone lead me to some small SUVs that are Naturally Aspirated and if turbo, are well put together. I currently own a 2008 Honda Accord, but it has 265,000 miles on it and it has been giving me some issues the last two years. Leaking oil, o2 issues, etc... I am just tired of putting money into it and looking for a reliable new, small SUV. I know Hondas, Lexus and Toyota have been reliable vehicles in the past. I live in the South Suburbs of Chicago and looking to raise the vehicle off the ground, meaning, it is hard to see during the winter months, when you are riding behind other vehicles and don't get me started on the rocks hitting the windshield. Any help, I would appreciate it.

Me, a 2012.Chevy cruze turbo owner attempting to learn more about turbos, knowing just how bad I hate my car, hears the exact make an model at the end of the video. I just knew it was coming... lmao. Im learning to love my little missile. Even if I have to go back and un-do GMs engineering and use after market upgrades. Cant be mechanically stupid and poor if you own one of these damn cars lol

Except the B58 with oil changes done at 5k Intervals 🙂

I plan on buying a Mazda CX 5 in December, would the regular non turbo engine be enough to get to 65 MPH when getting on the interstate from the off ramp? That's pretty much all I need.

Turbo's suck for daily drivers. They are meant for performance cars that are not driven a lot.

How reliable are 1.6l turbos?

What about the Mazda cx9 turbo?

I have a 07 Acura RDX and she is at almost 260k miles and is still all original

All semi trucks have turbos and often go over a million miles with no problems. I had a Cummins engine with 1.2 million miles on it and still running fine when I sold it. You just have to take care of them.

Is Mercedes GLC 300 2023 models turbo engine reliable?

mark what happen to getting rid of the moving parts like distribitor,carburator less moving part less problems.great channel

Car Master 🙏

Just when I thought I wouldn’t be in the list(Honda accord) 😂😂

I had over 700K with no problems related to the turbo on my vehicle when I sold it. 2016 Freightliner Cascadia.....
