A while ago on a (hot rodders .com) forum a rather respectable gent had said if you run synthetic fluids all through your vehicle your gonna get better mileage. Even 1 mpg for my expedition would be neat.
The only thing i question, is it gets 116 here in my area, and the coldest day last year was 30° many o nights its 100° at midnight.
Would running a synthetic oil give the motor more pep and help promote better mpg or is my area the type where i may wanna run a thicker oil ? I know everyone says manufacture knows best. Mine has about 95k on the ticker and the cap says 530. Im considering to either go full synthetic next change or to a high mileage oil, if 100k is considered high mileage anymore....
