And 5W30 is specified on newer engines because it provides more power and better mileage than thicker oils.

5W-30 is recommended and since its thinner than 10W-30 the engine will turn easier resulting in more power.

Toyota Canada recommends 5w30 year round here in the Canadian Climate.

I think 10w30 is what I run in my 2.7;

when in doubt.. 10W-30. it's a one size fits all type oil.

i think the newer engines recommend 5w30 for all-around usage.


Just for kicks, I actually called two different Toyota Stealerships. And just as I suspected, one recommended only 10w30, the other only 5w30. Interesting. I'll probably change it out with the remaining 10w30 I have from the pickup. I have 5 quarts left, no need to waste it all.
