Has anyone used Mobil 1 synthetic oil viscosity 0-30 in their pruis? Ive been using synthetic 5-30 since car was new.
I own a 2006 Pruis with 63000 Miles. I changed the fluid in the trans @ 50,000 with OEM fluid. I was wondering if anyone out their ever used 100% synthetic in their trans. Is it approved by toyota & what would be the advantages.
