I'm going replace the OEM tranny and gear oil very soon and after reading on forum which deal with the E46 ( BMW 3-series 99+) I've understood that the preferred aftermarket oil is either Red Line or Royal Purple.
Price not being an issue, which of the two companies would you gents recommend?
Now keep in mind that it can hit -30 Celcius here in the winter time, so cold weather 'performance' is a factor that I need to consider.
I've e-mailed Royal Purple about which oil they recommend, and i'll be adding this info to the thread as soon as I get a response from them.
Red Line suggested D4-ATF for the Tranny and P/S and 75W90 for the Differential.
Any preliminary opinions?
