"they upped the compression, changed the header, tweaked on the ecu, and some other small stuff. the new SAE rating took away roughly .8 hp from the entire toyota line (tacoma went from 245 - 235, same exact motor)"

Also they added oil squirters in all 07+ Scion tC's.

 

on page 227, of my owners manual, it says that 5w-20, 0w-20, but it also says that 5w-30is the best for good fuel economy and that 0w-20, is good for cold weather

 

I have an 05 and recently got my oil change at the dealer,they put 0W-20 synthetic.....

 

You should of asked them why they put that in instead of 5W-30. Whenever I look over any services done by someone else with my car I always double check on paper what was done and ask why if I didn't know already.

 

mine uses 5-20

 

I run Mobil 1 5W-20, and 1/2 quart of Lucal oil stabilizer

 

my oil cap says 5w-20 or 0w-20 so its not innacurate info
