So my buddy and I went out to his shop to change the diff fluid. I bought everything ahead of time according to Haynes manual and owner's manual.
Anyway, AFTER we drained the diff fluid I noticed that a tag on the cover of my 2001 GT diff said use 75/140 synth only. Of course we had 80/90 dino oil
Car was apart, no choice but to use what we had... That was 3000 miles ago and so far no problems. How high of a priority should I make it to correct this situation. Do I even need to? And yes, I did at least have the friction modifier and used it to spec...
