I have royal purpe gear oil that ive been wanting to change.... you cold out to do it... is it a good idea to do it ene though i highly doubt it has ever been changed? i have a 5 spd.. how many bottles/ liters does it take? just wanted your opinions thanks a lot

 

The gear oil should be cnaged every 30K miles.
It will take from 4.5 - 5 bottles to fill it up.
Make sure you get the right stuff for your weather conditions

 

it's 10 quarts isn't it? something like that.

 

5 quarts

 

About 10 for the automatic, about 5 for the manual.

 

thanks a lot
