View Full Version : Switching to Full Synthetic Oil

Does anyone have any suggestions for using Full Sythetic oil? I currently use 5w20 Castrol and was going to switch to 5w20 Castrol Syntec Full Sythetic. Hoping that it might get a little better MPG. I am currently getting around 18.5 to 20.2 mpg depending on traffic, etc.

I'm running Mobil 1, 0W30. Great winter starts. I'm also averaging 21 - 22 mpg, and based on oil analysis will be using a 7500 mile oil change interval.

I second the use of Mobil1. Great product!

Moved to Clinical Rounds.
Here's some reading!
I have used Mobil 1 and am now using Amsoil.
I believe the benefits outway the extra expense.
