I know I've seen posts on this before, but for giggles researched what my Corolla has for oil around the world. In the US 0w20 recommended. I think the manual says 5w30 in an emergency but should be changed back to 0w20. In Europe 0w30, 0w40, and 5w40 seem to be the options according to a couple different brand oil sites.

This makes me wonder...all the people on here asking, "can I run xw.xx in my car?" the answer has to literally be "any viscosity from 0w20 to 10w40 is fine." Aside from warranty issues, where I'd use what the manual says to be safe.

Thoughts, opinions, memes, facts, lies? Discuss.

Pretty much the truth.

Lots of mention from people that went from a 5W-20 to a 10W-30 and saw no change at all in fuel mileage.

I am really glad that 0W-20 exists for those folks up North in Jan/Fab, though....

Europe uses 30 and 40 in 90ish % of ICEs. The mandatory 20 is NA only.

USA=CAFE. I think that pretty much sums it up.

+1. My mazda states in Canada and Mexico to use 5w30, it that's not available then use 5w20. In the USA i must use 0w20 for the warranty.
Supposedly the skyactiv engines were designed for 0w20 , but that does not jive with the owners manual.

It's all CAFE.

My 2007 Accord specs 5w-20 here in Canada, but 5W-30 the U.K. Maybe because of colder Canadian winter temps? confused At any rate, I'll stick with 5w-20 per my manual, easy enough just to follow Honda's recommendation.

I understand in the USA the viscosity vs CAFE issue, but if the manufacturers run tests on engines to see what oil weight gives the best fuel economy, wear protection, ease of starting why not pin it down to
Quote:
one
weight and say "5w-30" world wide to cover both hot climates and cold climates per engine?

I wonder if CAFE dictates that a particular grade (say 0W-20) must be used even for warranty for it to count towards average fuel economy.

The truth is - most owner manuals say that in "high heat or towing higher viscosity oils may be used to prevent engine damage". So use what you want, and good luck finding cases of "rejected warranty due to oil viscosity"

Do engines last longer in Europe as a result?

What I find hilarious is guys thumping their chest saying they use 5w30 because they think it's thick oil. Sorry boys, it ain't!
