February 12, 201214 yr #1 hi guys what do you guys recommend for diff oil in a FG XR6T & when to change it? every 10k? cheers
February 12, 201214 yr #2 I did a bit of research and decided on Nulon 80w140 Full Synthetic in mine.
February 12, 201214 yr #4 nulon, castrol or penrite full synthetic are all fine.changing it depends on your driving conditions/how much or often you tow etc.every 30 000 maybe
February 14, 201214 yr #7 yer dont go by what ford say too much!Mine wouldnt last that long anyway the diff leaks, another fine example of Fords quality build
February 14, 201214 yr #8 I run nulon full syn as mentioned above, but I do recall someone saying recently that the full synthetics lessen the limited slip effect...
