Saturn 1.9 sohc oil viscosity vs mpg
It's coming up onto time to do a service on the poor Saturn
I am wondering if there is the potential for some low hanging mpg fruit to go down to a 5/20 full synthetic over the 5/30 conventional I'm sure is in the car.
I plan to also service the manual trans was well.
Thoughts
