Re: Oil Change Time ... Which and Why >>
Amsoil, Mobil 1, Royal Purple are all great 100% synthetic and will provide the very best in lubrication and protection. I've used all three and see no difference in performance, oil consumption, or fuel economy in my 2004 Z06 Corvette, my 1999 Dodge Dakota, or my 2003 Toyota Camry...
When I changed the fluids in my Z06 I went with Royal Purple and use it to this day. I did discover that the 6 speed shifts smoother and more consistent using Royal Purple over stock GM lubes.
Dodge Dakota SLT 4X4
My Dakota uses Mobil 1 in the motor and Amsoil full synthetic in the automatic transmission, front and rear differential.
Toyota Camry XLE
The Camry uses Mobil 1 in both the engine and transmission...
