I am planning to change the fuilds in my auto transmision and the differential and would like to know what is a good oil to use in each of these . I have a 99 Z3 2.8 Ken
I just had my manual trans and differential oils change at 74K and it jumped my mileage about 1.5 mpg according to the computer. Warning! Warning! BMW trans oil runs about $35 a quart. Manual trans takes 3 quarts. Automatic more. I understand Redline make good oil. J B
