So while I believe Amsoil SVG gear oils are top notch I am beginning to wonder if they are worth the extra cost.
Had the rear diff gear oil changed in my F250 recently. The Indy shop guy said it was dark and needed to be changed. Front diff was changed also but he said it was not dark like the rear diff. I am not in 4WD mode very often.
The rear diff gear oil (Amsoil SVG) had 53K miles on it. Very minor amount of towing and only 50 miles with my boat on a trailer (9000 lbs) and seldom anything in the pickup bed. So I would not consider it severe use.
I am thinking Valvoline full synthetic would do as good a job for less cost than Amsoil SVG.
I would have expected the Amsoil SVG to go 100K miles before it looked dark.
