I already use 5W30 full synthetic in my 2008 4cyl Highlander.


Why not switch to 5W-20?

Is 5w30 a thick oil now ?

Yes, it can be. See here. That's an HTHS of 3.5 or greater.

See page 271. This is owners manual for 2015 Camry sold in Russia. It is in Russian, but oil specs are in English.


weird, i'm seeing oils specs on the page 517 and not 271. nothing unusual here for the 4 cylinder, we have see that before from other countries (non-USA), all oils are good from 0w20 to 20w50, with some cold temp restrictions.

now, here is the shocker for the V6 engine. the 5W30 is only good for under 10C, only 10W30, 15W40, and 20W50 are good over 10C.

this is contrast to the USA recommendation that specifies only 0W20 or 5W30 oils for this same engine (depending on years).

WOW, this would explain why my 2GR-FE engine in RAV4 developed knocking noise when toyota dealer serviced it with 5w20 despite my objections (my year specification was 5W30).

this manual also shows that the V6 engine requires higher octanes in Russia. not so in the USA.

looks like there are more lies in USA than Russia. Who would have though?

which engine do you have, I4 or V6?

No shock to me. Makes perfect sense.

the octane rating could be calculated differently, like it is in europe. 95 Ron is the lowest available grade in europe, typically.

Here's a Toyota one from Oz, different engine, but indicitive that depending on where they are targeting their market, they offer "different" promises.

Both engines in the book (Hilux) can handle the lowest common denominator 91RON...but obviously the 1GR-FE is being neutered on "regular" by some anti knock process, that is freed up on premium.

My 1990 4Runner with 3VZE gave same cost per mile on regular and premium...more per tank, and more power on premium.
