I’m In the oil industry. The thinner oils are for fuel economy only. All of these energy saving oils will not meet European specs for sheer. I run Castrol Edge Euro 0w-40 in my 5.0. Gives solid cold flow and the 40 is on the lighter end of the spectrum and gives you plenty of protection at higher temps. The 5w-20 is a 20 at 212 degrees. If you are working a vehicle hard and the temps are over 212 you no longer have a 20w. I’d always recommend going up a weight. Won’t hurt the engine at all. The lighter oils on the cape and manuals are “recommended “ not “required” for vehicle operation.

Thx for simplifying it buddy, that was a good video. Saved. Liked.

Thanks buddy for the video I just picked up a oil change for my 04 Ford f150 4.6 and I got 5w-30 👌instead of 5w-20.

Great video and explanation, as a non car guy you teach me with a simple way a lot! Thanks!!

On my car, it says 0-20 on the oil cap. When i use that, the car burns oil. In the manual there are 3 options, 0-20, 0-30 and 5-30. Now i use 5-30 dexos1 gen2. No oil consumption, no problem.

I think you summed it up well. Regular cars can run 0w-20 all day long because it's never at sustained high load and cylinder temps. High performance forced induction cars, trucks and tractors tend to need the thicker oil to maintain the film and oil pressure. What tends to kill regular cars is simply neglect, not the oil itself.

I been running Mobil 1 5w30 for years in my 2003 cobra. I had a mechanic that builds mod motors tell me 20w wasn't thick enough. Makes sense with all the heat.

I’m glad you made this vid as I too wondered about using 5w30 instead of 5w20

Bro love this vid. You explained things simply and not with all this other bs about products and sh*t like most of vids ive seen. Ty!

Protection over fuel economy. The decision shouldn't be too difficult.

I agree with your also agree with RIGHTEOUS comment climate is something to consider, I live in Houston/Tx and here the summer is HOT so I do use 5w-30 (not 5w-20) if I was is a place that is really cool (below or at 0) I will go with thinner oil for sure, Also there are Engines that You need to follow the OEM Recommendation because the CHANNEL of the oil (the Lifters in this case and ) in some places of the engine is so small that a Thinner oil is needed for better lubrication an example is the DODGE Challenger with HEMI V8 engine. Thanks for your video.

Great video. I've heard Ford Mechanics say to run 5/30 and not the Ford recommended 5/20 because of Cam phaser issues that the thinner oil causes.

I run synthetic 5w30 in my 98GT. I store it 11/1-4/1 though too. No winter driving

Excellent illustration of how B.S. CAFE standards altered oil recommendations on these cars, even when the engine design never changed. Ever since i watched a FordTechMakuloco video where he mentioned he uses only synthetic 5W30 in all the 5.4 3V motors he works on i have never gone back to 5w20. I dont baby either of my cars so it gives me peace of mind to know my oil can handle the abuse.

Definitely answers my question, thank you! Question for anyone to answer... I have a 2009 Mazda CX-9 with 156K miles. I started losing power for pickup, and eventually was getting a metallic chugging sound when I turned corners. I took it three different auto shops and nobody could replicate the problem, or so they said. I kept asking if there were a problem with any of the fluids. All three said no each time. In the end, a fourth shop identified the problem... I only had one quart of oil left in the whole system! In my mind, oil is a fluid, but apparently I am wrong. But now I am worried about damage. It does seem I am burning oil, not leaking it. The good mechanic put 5 W 30, which is why I am here educating myself on the difference. Do any of you think I should go even higher?

Nice description. I use Castrol 10w60 in my 392 MOPAR. it loves it. Warm here in SOCal

Honey analogy is excellent

If you have high mileage like over one hundred thousand miles you can go up in viscosity. Instead of 5/20 go 5/30.

I did a ton of research on this, I run 10w30 with mmo in my 2.4l jeep. Calls for 5w20. Great video love oil talk, everyone's got their own flavor and weight... catch can anyone?

I have a 2016 Yukon XL and i dumped the 0/20 and changed it up to 0/40. I also changed the cap to that that says 0/40 ...with the original 0/20 cap I drilled a hole as big ss the inner diameter of the cap...right thru to be used as my leak proof oil funnel holder during oil changes. I also run 5/40 in my 2008 Nissan Pathfinder V8. CAFE wanted 5/20 in those. I also changed the cap with one that dont have any viscosity printing on them. (Intl spec nissan oil cap) I have never followed CAFE specs. Ive always followed EU oil reccomendations.the only CAFE i follow is the brewed kind. 😉

Good video with good info, i have a 2012 corvette LS3 engine, I’ve always used Royal Purple 5W 20 after warranty expired. Haven’t noticed any difference with the 30 to 20 with my style of driving. I probably baby it more than I let it rip but I do go on 300 to 400 miles trips. MPG is still average 16 city/ 26-27 hwy. I don’t think it’s much of a big noticeable difference in regular driving, at least i haven’t and don’t expect to. Good maintenance and care really helps in whatever oils you decide. Again that’s just what I think if one is just regular driving.

Great video, I have a 2012 GT with a 120,000 . Started its life from 32k with Royal Purple until 80k. Shop didnt carry anymore. So switched to Valvoline Max High Milage Synthetic. May burn a quart to a quart and a half between a 5k oil change. But remember this is still a 5w-20. Non modified motor, not one oil leak, spirited driving, daily driver. These gen 1 motors and Chevy LS motors are bullet proof. Its lost HP by mathematically engine years, however dosent feel like it. Wondering if I will even have to rebuild at 200k. Just FYI on high milage coyote motor .

09 Toyota Prado , book says 5w 30, but now using full synthetic 5w 40, much smoother than 30, and I live in a hot tropical climate in Asia where temps don't dip below 30C/88F, so a bit thicker oil makes more sense.

5w50 Amsoil Signature Series in my 2012 Shelby GT500. 5w30 Amsoil Signature Series in my 1996 Toyota Avalon 0w20 Amsoil Signature Series in my 2021 Jeep rubicon 3.6 v6 As of 4/23, I’ve switched from 0w20 to 0w30 Amsoil Signature Series in my 2021 Jeep rubicon. Night and day difference on start up. Super quiet with the 0w30 and less blow by caught in the catch can. Like over 1/2 the amount less from 0w20. My 2018 Raptor gets 5w30 Amsoil signature series and I and hardly tell the engine is running it’s so quiet and smooth.

It's always fun to hear and read what people say about oils. I would say that most people have at least some truth to what they say about the oils that they use. Me? I'm still just learning, so thank you to the other commenters.

Haha, I just changed my oil in my 2003 Ford SD 250 5.4l and forgot which weight of oil because it's sratched off the cap. I Googled and it said 5w-30, so I started to put it in and decided to check my manual to see the amount and it said 5w-20! I came here and to my relief it sounds like it's a better oil, plus it's summer too so it doesn't sound like a problem. Thanks for the info y'all.

I only use full synthetics when I change my oil, 5w30 or 10w30 in my out of warranty 2016 Turbo. In warranty Sportage has free lifetime oil changes, they use 5w20 Mobile 1 blend, in the winter under 68F I leave it alone, come summer I take a jug of full synthetics 10w30 to them and hope they actually use it. Why does no one who discusses viscosity ever refer to a viscosity chart? And I don't mean the one supplied in the owners manual that they can control.

As defined by the SAE 5w-30 is also a 5w-20 as it exceeds the SAE viscosity test requirements for 5W-200. This equally applies to a 0w-40 or 5w-40.

Was w/ U all tha way Broski, from when u snappd the bolt, till u extracted it!! So Fu*k evry Troll’n “Know-it-all” Kook’s negative comment u come across, bc they didnt knw how 2do it @sum point n their lives either. U learn by doing, sometimes mistakes r made, sometimes not, but nxt time U’ll b that much better @it..Glad u stuck n thru whole Vid, Proud of U🤙🏾

My everyday driver is a 98' lexus gs400, live in South Florida, I've always run 5w30 as factory recommended, car drives great with almost $230k miles on odometer.

My 2018 2.4L 4 cylinder Ram Promaster City van recommends 5w20.. but consumes oil. I live in Hot Florida. Okay to use 5w30?

I wanna run 5w30 in my 09 gt mustang i live in New Mexico where it’s hot I was wondering if the cam phasers need thinner oil like 5w 20 or if 5w 30 is fine

Ima go with 5w-30 I live in AZ summer is right around the corner lol only weekends for the Stang now got a daily so I can let my Stang rest and finish FBOing it.

An article by a Lube magazine said 30W is optimal viscosity for an engine. Also they said Ford trucks in in North America use 20W, but in Europe, Ford trucks use 30W to comply with factory warranties.

I agree. 5W-20 was fine for my 2002 Ranger V6 that never used much oil, but not for a supercharged V8. My 95 Toyota truck calls for 10W-30. I use 5W-30.

your definitely right in running 5w30 I have a 2010 track pack GT and it says in the owner's manual 5w20 for fuel mileage but to run 5w30 for hard driving racing or track use so that right there says 5w30 won't hurt it not to mention who has a Mustang that don't run it hard. i would not go any thicker but supercharged definitely hard on the oil i would only trust #1 amsoil or #2 mobil 1 By the way wicked wicked Terminator cobra

I’m in Massachusetts. Very cold and very hot. I have a 2020 civic si. It takes 0w20. I notice during the day the engine runs different comparing to when it’s chilly outside at night. Is it ok if I switch to 5w30. A lot of people told me to do that.

my first thought is would you need to upgrade your oil pump to run the 30 weight ?

94 mustang GT/ I run synthetic 5W-30

5w30 in summer and 5w20 in winter on my 5.0 F-150 👍

I've run 5w30 for the entire life of my 06 mustang gt, but i can't help but think we should all still be running 10w30 unless you live in the Northern most points of the globe.

Thanks for the video. I bought a new Hyundai Elantra in 2018. I change the oil every 4k. I use a Mobil 1 filter and synthetic oil. Yah, I'm throwing my money away, I should go another 2k. Anyway. The oil cap says 5w20. The manual has 5w20 and 5w30 listed in the same temp range, and 10w30 when it's warmer...i have 56k on the car and have always used 5w20. Last oil change I changed over to 5w30. This will leave a little more film on the moving parts and add a little more protection when the engine is hot. Heat is what ultimately kills engines, unless it's a chrysler, then it's just junk. Sorry for adding that. I was so burned by them in the past I never got over it...

I run 5w-30 in my 2012 Raptor. 6.2L v8 that sees lots of hard desert off road miles. After 180k miles it runs like a dream and uses no oil between oil changes. Like you said, for normal daily driving 5w-20 would be ok. For hard driving 5W-30 is the better choice. 🙌🏼 im a master mechanic with 25 years of experience BTW

Def depends on bearing clearances and application for built engines… from what I know they go with more clearance,,,, and call for thicker oil. Valvoline VR1. To the the flow to cool bearings down

what about in a 2014 mustang gt coyote with 52k miles? on the cap it says 5w20 and that's what i have ran the past 3 oil changes. the car isn't raced just a few pulls here and there.

Yo would u run 5w30 in a 2011 honda civic ...? It calls for 5w20....not in a very cold area pretty neutral year round....what do u think?

I work at chevy dealership and that Mobil 1 5w30 is the one we use for c6 c7 Corvette. Best and pricey oil we have

Climate is also something to take into consideration. I ive close to Houston and our summers are brutal hot. I run 5w 30 because of the better protection in the heat. I may get slightly worse fuel mileage,but I feel in the heat the added weight is better in hot conditions than the thinner 20 weight. I might not get as good of a flow rate,but as hot as it gets here in the summer..I believe it's the better choice in the summer months

5W20 Amsoil synthetic signature series oil is my go to oil with a motocraft oil filter !

Ford says 5w-20 . . . I live in HOT Arizona, should I go with 5w-30 ?? thnx and good vid

Well said

I have been using Straight 30w in my 71 302 now im going to get 5w 30 now

My volvo xc70 2.4D needs normally 0w30 I use Kroon Helar 0w40. (Full synthetic) I live in Europa but drive few times a year to Siberië. My automatic transmission i use Kroon sp matic 4026 In my diff's and transfercase i use Kroon gearlube racing 75w140 ( full synthetic) because i drive continue with a 3000kg and a high trailer. In my haldex i use Kroon sp fluid 6033.

I'm not sure which weight between the 20 and 30 are currently in the Cobra when I got but when I do the first oil change I'm going to run 5W30

I always ran 5w-30 in every new edge mustang I’ve ever owned. I figured it’s a car I’m going to run hard and I want an oil that’s going to hold up to heat.

I have a 2010 Honda Element that calls for 5w20 on the cap but i have only used that twice. Didn't notice any difference in fuel mileage with the 5w30. I looked at what same engine called for in Japan and it listed several weights to use depending on the temp. I normally use Pennzoil Platinum but recently started using Pennzoil Euro changing around 5000 miles. It has 148K on it still running like new with no oil use. The car companies don't want your engine to last for a long time they just want it to get past the warranty then it's all on you

I´v seen several videos on the 0w-20s and 0w16s and not one has asked if there is a loose of Power! If the oil thins out too much the cylinders will loose compression! It seems to me the auto manufactuers preasured by the enviormentalist have thrown the Viscosity Charts out the window saying "Viscosity Science No Longer Maters"! Time will tell if the 20 weight oils will hold up or if we see a generation of blown engins.

Thank you. I was under my 2008 P71 Crown Vic yesterday changing the oil. I put in 5/30, and then I had second thoughts when I saw the 5/20 on the cap. Should I dump the 5/30 and start all over again with 5/20? Will the 5/30 trash my engine?

Using 5w20 I lose oil in my 2004 Ranger 2.3 4cylinder. From oil change to when I want to change it again I find I'm losing more than half a quart. I'm thinking of changing it again now using 10w30 full synthetic. Is this a bad idea?

Great video Danny! Question for you: I’ve always ran 5W20 in my 03 Mustang GT. Would it be beneficial to make the switch to 5W30? Also, would making this change cause any damage/adverse consequences to the motor? Thank you, really appreciate it! 👍🏻

I live near Chicago and own a Fiesta ST. What oil would you recommend for winter and what oil would you recommend for summer?

So I have a 2015 Legacy and it calls for 0W-20 but it burns a little bit of oil. Maybe a quart in the 5K between oil changes. Can I safely switch to 5W-20

I have a 2006 civic w/257k and the oil cap says 5w20 but with that mileage should I be ok running 5w30 I live in central Tx

My car calls for 0w20 so that's what I'll use, but I might switch to 5w30 once the engine gets some serious miles on it.

I have heard that the first number in the oil viscosity rating is the viscosity number for the base oil. Additives allow the final product to function as a 30 weight oil (5W30) when the oil is hot. These additives break down over time with the result that the viscosity does not maintain the performance of the 30 weight oil when hot. So...if you wait too long to change your oil, you are really running straight 5 weight oil when hot. This thin oil will not protect against metal-on-metal contact in the engine when hot. I drive infrequently, but I still change my oil at least once a year. Usually get 3000-5000 miles on a change. So far, no oil related failures.

You'll know it's a good oil, when the worst motors are still going strong with the PUP, I too whatched the oil shootout video years ago, researched PUP, and guys in The subaru forums were sending thier oil out analysis after a change over to PUP , and had good results .

I had read the same info back in 2001, A friend had a 2000 ford taurus that took 5W30 and I bought a new 2001 ford taurus and it said 5W20 oil, our engines were identical and that started me wondering why. The 5W20 does not protect the engine as well as a thicker oil. I run Castrol Edge 0W40 oil in my 6 gen SS Camaro and my 2020 F-150 Coyote

Greta video. Thank you. Awesome motor

Hi Danny. I have 2007 mazda 3 2.3L with more than 100,000 miles. The cap says use 5w20 but my mechanic recommended 5w30 because of the high mileage. What is your opinion on this? Would you 5w30? Thank you.

I use Mobil1 5W30 with WIX filter in my 2.0L Ford, 3.6L Buick, & 5.2L Dodge! Every 5K miles.

A newer video has popped up. It showed 0W20 had more metal particles in it than 5W30 after both were run hard in a high HP engine.

Supercharged or Turbo? I'd go right to a 10w40 or 15w50 M1.

Avalon 176K miles going strong with 5w-30

Use recommended 5w-20 Mobile 1 synthetic in my Crown Vic Police Interceptor. Has 205k been using that since 102k it absolutely purrs doesn't burn a drop change it every 7500. Should I go to 5w-30. Live in Coastal Calif never got never cold.

The manufacturers don't care so much about longevity, as long at an engine lasts through the warrantee period (typically 36,000 these days) they are happy. On most vehicles, the oil weight called for in other countries, Australia for example, is heavier oil. That means that the engine will handle a 30 weight oil with no problem at all.

Ow oils slip off metal. The parts are dry if we park a while. Check dip stick. 5w30 stopped soot in tail pipe! Gas cleaner 2 tanks. Better running and quieter also.

Can I use 5w30 in a Malibu 2.5 Ecotec?

0w20 protects just as much as 5w30, but that lower HTHS thinner oil relies more heavily on its additives rather than viscosity index to offer the same protection at extremes. This means it is less forgiving if prolong high rpm, heavy towing , and prolonged oil changes on 0w20 when all additives have worn out and now more severely damaged engine vs same scenario if slightly thicker 5w30. I’ve done more major engine repairs for abused 0w20 Toyotas vs 5w30 with all things being equal on average throughout my 12yrs.

I've noticed better fuel savings on a thicker oil but might just be from having a really old and worn engine LOL it's not as sensitive as new engines would be I think lol

Can i use this on my isuzu trooper 4JG2 diesel engine 1994? We have no winter in our country Philippines. Pls advise.

I run 5W30 Mobil1 in my 99 since day one

My dodge caravan say 5W-20 can I put 5w30 in it

I just bought a used 2007 Honda CR-V...I was thinking of adding synthetic oil when the oil gets low. Is there any danger or problem if I mix regular and synthetic oil together? I was thinking adding alittle until I can change the oil at a later date

I'm in Northwest Georgia. I use Motorcraft synthetic blend 5w20 in my 2014 Mustang GT (63k miles) and 2012 Expedition (46k miles). I know the 5.4s can have issues if not maintained properly, so should I continue to use what I'm using or switch to 5w30?

how much fuel you save on 10,000km range by going from w30 to w20? thank you

how about run half of 20w oil and half of 30w oil , best of both worlds ? I have an 2003 honda accord 2.4 and this works great for me.

I have a 2018 2500 5.7 L hemi in my dodge. People are saying lifter failure and cam shaft failure are caused by the 20 weight oil. I’m always hauling heavy roofing materials up the mountain and doing mountain driving every day. Should I switch. I’m a roofer not a mechanic in a small mountain community trying to figure this all out. Thank you in advance.

In the Middle East, the temperature in the summer reaches 45 c , and car companies ask to put oil 5w20 .. unbelievable

Do you think 5w30 is safe to run in a 09 4.6 gt mustang it also says use 5w20 but it does get pretty hot in New Mexico I just put 5w30 oil in it I also just changed the cams with stock Ford cams timing chain lash adjusters an rockers an high volume meling oil pump because the stock cam got scored up from a roller rocker failing

I get it totally it depends on Mod's too.. I would run a 0/30 instead of a 5/30 in the winter's. I would only do that in Dec, to March, Then just go right back to the 5/30 when it's starts to warm back up around here.. 5/20 on a Mustang doesn't even sound right.. I have to use 5/30 on my 4 cylinder turbo Juke, And then use 5/20 on my GT it silly..

Good video...1st is go with Mobil one extended...it costs 10 cent more a quart and its as strong in every way that Mobil one makes...20k miles....2nd ACEA ratings..its a European rating but its used in the US to indicate the best possible oil...Mobil one 5w20 has a A1 B1 rating..very good but not the best...Mobil one 5w30 has a ACEA rating of A1 B5...that's the top of the top for overall oil performance...your 4.6 supercharged mustang with a 5W20 oil cap probably isn't the best oil...I'm bet money your theory is correct..5w30 Mobil one 20k is a better oil....I have a 2006 Camry 2.4 liter 4 cylinder...since it was new I put 5w30 mobile one 20k ..it has 420k miles...which engine is tuffer on oil...your 4.6 twin cam super charger...my camry says 5w30 without exception..it still gets 35-38 mpg....I got a 2003 low miles Grand Marquis..its similar to your mustang engine..it has a 4.6 single over head cam...it says 5w20...I use 5w20 but in the extended 20k Mobil one..it gets 25 mpg in the highway...its a great engine...it seems great but yours has 2X the horsepower...my Camry engine only holds 4 quarts...my marquis holds 6 quarts.....just image how good the 5w30 mobile one 20k mile oil is with only 4 quarts for 420k miles and always 10k miles oil change intervals..if I had the mustang I would go 5w30 mobile one 20k or 10w30 Mobil one 20k.....or the same weight oil in Amsoil signature series...ACEA ratings are on the back of the bottle..very few oils have the maximum ACEA rating of A1 B5....heres some proof that the extended Mobil one is as good as they say..when I reach 8k to 12k miles on my oil it without exception gets a mile or two mpg better than it did when the oil just got changed...that's extraordinary

It would but more wear and tear on your engine if the oil is thinner so it makes sense to go thicker

the dealer has been using 5W-20W in my 2006 toyota corolla; it calls for 5W-30W. Why!!! I have 1OOK on a bullit proof engine and have changed the oil on time since it was new. From my receipts, it looks like its been the last 2 or 3 oil change. Have some valve train noise from about the time they changed the oil, according to my receipts, Thanks Cobb County Toyota in Kennesaw Georgia for shortening the life on my engine. Asshats!

My Kia Rio manual says to use either 5W-20 or 5W-30. However, if it never goes below freezing (it doesn't here in Arizona), it's ok to use 10W-30.

Run 5w 20 in winter and 5w 30 in summer, got it, lastly, every manufacturer tests the oil based on numerous points of circulatory lubrication, pump, flow ports, filter type, ect. The viscosity, chosen is a choice based on all the factors, just sayin, consider all the above.

I run Amsoil 10W30 Race Oil. Great stuff!

Which grade you recommend in Toyota Corolla GLi 2010 model,

I have a scion tc. 165k miles. I run Royal Purple 5w20 but my car eats through quite a bit of oil (not visibly burning a lot) should i go up to 5w30 to help?

I care more about better protection and durability than I do about gas mileage

My wife has 2017 Ford Fusion with the base 4 cylinder 2.5 liter (not turbo-chaged) engine. 5w-20 is recommended per owner manual, but thinking I should switch to 5w-30 especially now as that vehicle has 110k miles on it. Any opinions?
