Differential oil additive?
Hi everyone.
I am after some info for a F250 7.3L Turbo, 2003 model.
Changing the diff oils tomorrow, I'm using 75w140 GL-5 full synthetic (as required).
On other Ford high performance vehicles I have used an additive; Ford MOTORSPORT Friction Modifier M-19546-A
Can anyone tell me if this I can use this in the F250 LSD diff, back & front?
Also, what type of diffs do these F250's have?
Thanks in advance.
