I use what the manual recommends. 5W-30 right? Its early and I can't think but I'm pretty sure thats the magic number. May switch to a lighter weight soon to see if those MPG gains are for real. 1500 more miles until 20,000.

Nigal, since the Yaris only takes 3.9 quarts of oil there should be no reason not to use the best oil possible. I picked up 4 quarts at Summit Racing for $26. That is less than I'd pay the stealership to put dino oil in my car.

Well that's not too bad then. I think I payed about that much for 4 qts. of Mobile 1 . I'm not seeing a 0W20 weight oil on their web site though. 5W20 should be about the same, yes?

I know a bit more about oil.
In general, the first number tells how thin the oil can be when temp at cold, and the second number tells how thin the oil is when engine running hot.

So... it stays like 5-20 when hot.
So... it stays thiner than 5-20 when engine is cold.
So... it is pretty much ready to go even when the engin is cold.

Since we dont push hard our cars in any typical day, this Eneos oil stays thin to give engine easier load and therefore it saves gas a bit more. The downfall: since the oil is not as firm, the engine delivers less power . The other good thing about it is.... I think it is alright to chage oil every 10k mi (believe it or not), but i think I will do it every 6k mi.

Do some google about motor oil if you want to know more.

yes theres a lot more things that can be mentioned about oil viscocities and weights. but didnt think it was relevant here. i dont want to sound like a know-it-all, that gets annoying really fast
good info though

At least you realize it. I could give you a couple names you could PM to remind them of that very fact.
