65k Differential Fluid Change
Bought my Z from the original owner at just over 59,000 miles. Today I changed the differential fluid at just over 65,000 miles. The fluid was very dark, but not black, and definitely smelled burned. I suspect the fluid was the production fill. Additionally, the magnetic drain plug had a heavy coating. The coating came of with paper towels and had the viscosity of a thick paste.
Given the heavy coating on the magnet, I will be changing this fluid during my next oil chage. I'm sure there's still a decent amount of metal coating internal surfaces, and will be washed away by the new fluid. If you have not changed the differential fluid in your Z, I recommend you consider doing so.

i did mines @ 55k and the fluid was a dark honey color.
also, compared to the 350Z, changing the RD fluid is a tight squeeze for the 370Z, as I had trouble getting my torch wrench to fit with the exhaust piping in the way. |

Did you mean "torque" wrench? I'm pretty sure you didn't use a torch during your fluid change. |
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. |

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. |
I change mine ever 60k miles with redline, been good.
On a side note filling it can be a bitch, i'll post a pic later of the pump I made. Used a new syrup pump from starbucks cut down it fit in a redline bottle. |
^^ I agree, I do lots of hwy driving and I know for a fact that fluid heats up pretty good at those speeds over time. I'll probably change it again during my 18k oil change...just to see what it looks like after about 12k miles of use
^^ @ 90 ST.....dude, just get the cheapest pump from any auto store like auto zone, it worked perfectly for me |
