65k Differential Fluid Change

D.Stillwell

I changed mine at around 6k miles and already it looked like crap. Also with the factory fill I used to get this light burning type smell coming from the diff when driving hard..I think the factory fluid is garbage

Now that is all gone, I used Motul 75w90 its very easy to DIY on this job.

It would be interesting, albeit expensive, to see what the Motul product looks and smells like at 6k of similar driving.

From what I've read, it is reported by those with differential fluid temperature sensors in their 370zs that the fluid temp continually rises when driven at constant high speeds. For those who regularly drive an above average number of highway miles, I reccomend more frequent differential fluid changes than the interval specified by Nissan.
