Thanks for watching, guys! We look forward to hearing your thoughts and feedback on this controversial subject!

Ive got an 02 Durango 4.7 i use that T4 triple protection 15w40 all year i live in new jersey never had a problem the 15w40 is good till about 15 degrees F

I can't believe I actually enjoyed learning about oil! I swear Ben & Ben make everything more interesting.

You learn something new every day!! Cheers mate 👍👍

The best explanation about oil codes and viscosity. I have been watching lots of videos none of them was clear even the engineers doesn't know how to explain. Your explanation is so simple and understandable. Thanks.

Really useful advice like always, great work guys👌🏻💪🏻

Thank you for this quality video, definitely enjoyed it!

Thanks for the video, I didn't really learn anything in particular but it was good information well presented and your video quality is fantastic. Happy holidays! :) Personally I'm a huge fan of synthetic, I picked up about 0.5MPG consistently switching from conventional the previous owner had in the vehicle to synthetic 5w-30 in my 08 Ford Escape V6 with 215K miles. When I switched from conventional 5w-30 to Royal Purple HPS 5w-30 in my 92 Chevy 1500 V8 I actually gained 1-1.5MPG and the engine got much quieter. I did try regular (non-HPS) Royal Purple in the Escape and it was not any better than other synthetic so no point in spending extra and I use whatever brand I got on sale, Valvoline, Havoline, o'reilly oil, etc.

Amazing video you guys are awesome this really helped me with my Subaru

EXCELLENT job ! ! ! You took a confusing subject and made it understandable.

My Dodge journey: 5w30 on winter 10w30 rest of the year. *New Hampshire and Massachusetts

I really appreciate the nicely installed insulation for the backdrop

U guyz never disappoint! Best video on engine oil grades

Great information and break down!

great video, shared and liked

Actually learned a lot from this!

Nicely explained

One thing look at also is oil analysis trends on forums for your specific engine and oil brand it tends to like. For duramaxs for example it really dont matter what you dump into them, oil analysis is always great. Some engines do show better results with some brands like amsoil or other real high end syn oils.

great vid! i was wondering how oils of 0W, 5W, or even 10W up behaves during summer season, say 25 degrees C.

My personal opinion is if your owner's manual says you can use 5W-30 or 10W-30 then there is no reason you can't use 0W-30. All three oils are giving you the same protection at operating temperature as a straight SAE30 oil.

I live in Canada and we get some really cold winters up here in Northern Ontario, we also get some really hot days, so I use 10W-30 Mobil 1 Full Synthetic Annual for the Summer and the 5W-30 for the winter. Don't forget to check your oil every fill up. Also in the winter don't just start and go. Let her warm up. Most modern cars are coming with remote start on the keyfobs they give so take advantage of that and click your keyfob a good 5 - 10 minutes before your ready to go. Also I like to not drive the car until my oil reaches at least 0C. Ill get in my Charger after 5 minutes, check my oil temp and and if its still in the negatives I'll sit in her give it a minute or so then gradually rev it up to a higher rpm for a few seconds. This creates a bit more heat. I'm not gunning it, I'm just bring it up by about 500 to 1000 rpm and slowly so its not working that hard. It gets it warmer a bit faster and better than just putting it in gear and driving it. Once I'm up to 0 I'm off. From there temp climbs relatively quickly. Winter is coming. :)

That's brotella to you sirs

Luv how the video starts 😅

Castrol 0w40 is amazing. I have almost 160k miles and haven't had problems. Recommended for the vq engines.

Hey man. Im driving accord 2.4 9thgen. The factory suggest to use 0w-20 engine oil. However, i already turbocharge the engine. Need to upgrade the viscosity to fight the heat. Should i'll go for 0w-40 or else. Thanks

Putting back some life in an old thread. W can sometimes be referred to weight or winter. For viscosity it is recommended to keep around what is advised by the manufacturer. This is because the oils gaskets, bearing tolerance level etc are all tested at the manufacturers recommended levels. Running anything lower can also cause minimal oil leaks and running anything much heavier can also cause gaskets to die out a lot quicker. My thoughts and experience. BTW great channel guys, deserves more recognition ! Love the video edits....

did you prop the boards up at the same angle for each test? seems like you were holding then up by hand. They would definitely affect outcome.

Awesome video as always fellas!

The gymbal shots are addicting

RVA crew shown' up!

Does not matter, as long as you use approved oil, it will not affect your engine.

You should run whatever it specifies in the user manual, from there, many people have done tests with many different oils in sub-zero environments. Mobil 1 is one of the better oils.

I run 10w40 in my corolla all year long, it calls for 5w30, but the engine is worn and it burns through it too quick, when it gets really cold wich is hardly ever, I live in Virginia usually doesn't get below 20 here I let it warm up for 10 mins, if anything running thicker oil has helped it, it seems to make better power and it doesnt burn through it as quick

Question to ponder uppon. 🤔 what about a high mile engine, the wear on the piston rings and bearings. Wouldnt that require a higher viscosity to conpensate oil presure. i.e. if a new engine requires for example 5W-20 for the first 75,000. Once it passes that mark shouldn't it be a thicker viscosity due to the wear on the internal componets. ? What are your thoughts on this as only cold starts where discussed in theory...

The only thing I don't understand is what anything higher than 0w even exists.. Even if the outside temperature is warm surely a thinner cold start oil is always better? I can only guess the chance of burning/leaking during the warm up

This is scientific because this is what you would call observational science. I hear alot of guys say that in almost all of the videos.

Plz recomend engine oil for bike in temp btwn 5 to 25°c

my car is running on 10w30 but in here winter is very harsh, can i run 0w30 or 5w30?? it runs on 1jzge vvti non turbo

Mobil1 0w40 is the best oil i ever used No matter if its used in winter or sommer All of my six cylinders got it and everything got better

that rotella t6 0w40 must be new oil, never seen it before.

I'd like to see warmed up oil versus cold of the same weight. According to your explanation the warmed up oil would flow slower than the cold.

I always just squeeze my pizza over the filler it's a perfect winter top up ✌🏻

On my 2014 WRX, Subaru says to use 5W-30 full synthetic. I switched over to Shell Rotella T6 5W-40 for the Winter. I may go back to 5W-30 in the Spring/Summer and see how things go. I'm more interested in what brands people are using. My first oil change was with Mobil 1 but a lot of people in the Subaru community said to move away from it since it breaks down quicker than other brands in the EJ25X motors. Last 2 have been with Shell Rotella, but the garage I will be having do work on my car at uses MOTUL exclusively.

At start-up, I want to know that some oil has remained (clung to) my valve train, from the previous run (at operating temp.) Won't the synthetic completely drain away from the valve train?

This channel is like a fine wine keeps getting better!

T6 40 weight in my 03 tdi. 5w in summer and 0w in winter.

Are they in Celsius or Fahrenheit?

Guys i am planning to buy an old car i always dreamed of (Opel GT). What do i need to consider for fuel? I read that our gasoline is not too good for carburators

So I can safely use 0w-20 over 5w-20? I live in L.A. so it never falls below freezing.

This is why I leave my power strokes block heaters plugged in during the winter....

Great video production. Little actual info about oils.

Even after 1p video i didn't gotvthe fact how the viscosity is less when its cold than hot , i men in cold viscosity is 5(less) when running hot 30(more ) , while it get hot it should be thinner and thicker in cold

What if the temp goes up to 70 in Feb. It does happen.

The same oil I use all year round.

Baby oil for Hondas

0W is good for -30 and 5W is good for -25. Either one is fine. New England doesn’t even get to these low temperatures.

MT winter is average morning about 0C or 30F. I use 15w40, easy.

Since when does Jason from engeneering explained wear a cap?

5w-20 all year round just like the manual calls for.

TL;DR Use whatever is recommended in your owners manual...

I use 10w 60 Mobil 1

Conventional is hard to find? About a third of what Advance currently carries is conventional.

i have a chevy cruze the wife and I use for commuting and errands we live in idaho. We run full synthetic 5w30 which is whats recommended and might consider doing like my dad used to do and switch to a lower 0w30 at some point.

I use 5w-20 oil recommended by the manufacturer regardless the climate

So the thing that I still don’t understand is what is the benefit of a higher weight at all?

I live in southern CA and was told by my mechanic to use liqui moly 10w60 in my 2008 997 porsche 4S

So I run 5W-40 from my Audi dealer in my 2013 Audi S4 with 77k miles on. Totally stock, do I need to change the oil in winter. Also I do my oil changes every 10k.

😂 Mobil 1 CONVENTIONAL!! 8:29 The correct name of The CONVENTIONAL oil is: MOBIL SUPER

Is there any reason not to use 0W year round?

But it’s summer for me (in Australia)

Compare a cold 5w-30 to a lukewarm 10w-30.

0W-30 Castrol Euro Blend for my BMW E82 128i. Runs like a champ at 167k miles.

Where's subaruuuu!! 😂😂😂 need more of that

Why not run a 0W oil no matter which climate you live in since it would be thinner and provide better protection at startup than a 5W or10W in all cases?

Question. Why use 10w when 0w is clearly superior ?

Anyone here ever use Lucas Stabilizer Pure Synthetic in below zero weather?

4:50 seating in your...engine ?

No car reviews??

The way this dude pronounces syrup.

It bothers me that you call it conventional Mobil 1when it says "Mobil Super" right on the bottle you're holding.

What kind of engine oil should you use in the winter? Watch up pour oil down boards for 10 minutes to tell you we don't know...

Read the Owners Manual!!

Were is the legacy

The w in the numbers doesn’t mean winter it means warm viscosity.

Use 0/20 full synthetic Best in winter.

What about rotarys do they use mtn dew as oil ?

Great presentation. Just a shame you didn't answer the reason I clicked on your video

Luckily i don't have winter in my country

How about -10 or -20...

So is letting you're car warm up before you drive it when it's cold out a good idea, or is that a myth?

Use the same oil in the winter and summer. Sleep easy...

Didnt know you had to use different oils for the seasons #themoreyouknow

0/20 or 5/20 in cold climate.

0w20 will flow faster with any full synthetics. Just follow your owners manual, as we do not live in the North Pole, no need to overkill.

Doesn't the "W" in 10w30 stand for weight, not winter?

learn yourself, then teach others. 0w40 and 10w40 will NOT behave same in operating temperature. also 10w40 and 10w60 will NOT behave same in cold condition.

Want an opinion from an actual chemist? Synthetic is best. There are 5 groups of oil. 1-5. 5 being the purest structures that are made in the lab (esters, polyglycols and silicone). You don't really run these in their own but are often additives. Group 4 are laboratory built oils as well which are synthetically built polyalphaolefins. These have fantastic range of benefits from higher flash point, viscosity, range of operating Temp etc. These are your best oils. Example being Amsoil and potentially Pennzoil Ultra/Platinum brands (Pennz is made from natural gas which mimics a lot of the behaviour including better viscosity). Grade 3 is the majority of the rest of oils...Mobil 1, Castrol, Royal Purple etc. Etc. Group 2 and below = do not purchase.

I disagree with your stigmatization of conventional oil. A conventional oil will protect more-or-less as well as a synthetic oil of the same grade, just will typically need an oil change more often due to less oxidation stability. Also note that per API standards, a 0/5/10W-40 oil is allowed a minimum High Temperature High Shear rate of 3.5 mPas, while 15w-40 has a minimum of 3.7 Thus, the oil that flows worse at low temperatures can conceivably protect your engine marginally better at operating temperature.

just use your owner Manuel.. nothing else

It triggered my OCD that you just dumped the oil right on the table in your viscosity tests. Lay something down bro.
