5-w20 is what i use. i dont think there is any dire need to go 0-w20.

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.
