I have 50k miles on my car...
when should i change the MT fluid??
thanks

 

I would recommend it. MTF is one of those things that gets largely ignored when it comes to normal maintenance. For conventional fluids, 30k is probably a good interval. There have been a few interesting analysis' done with less mileage that would tend to support this.

 

If you are using Nissan OEM MT fluid every 10K:

I change every 30k miles.

 

the service manual says every 60k...

ALEX: The copper and lead you see here could possibly be left over from the factory. These levels are not terribly high, but we think it's time to change out this oil, especially considering the insolubles level. We suggest resampling after 10,000 miles on fresh oil for another look at wear. The TBN read 6.5, which would be a routine find for and oil of this viscosity with these additives in it.

There was EXACTLY 15K miles on this Nissan MANUAL transfluid.

Copper = 36 Universal Average = 10
Lead = 7 Universal Average = 1

INSOLUBLES = 0.4% Should be = <0.1%


So, those of you who don't test your oil MIGHT want to change your MT fluid every 10K instead.

 

MT90 every 25k.

 

For the Nissan-OEM fluid, an early change is probably best. However, no analysis baselines have really been established on the longevity of Redline MT-90, Amsoil gear oil, etc.

 

Only 8K more to go!

 

Isn't that like 2 years of driving for you?

 

No...more like 1yr, but I'm racking them up fast lately so things may start happening sooner.
