I will soon be changing out to red line syn. and as far as i've read on here, some are using 75w90 ns and some are using the MT-90 ? which one is best? thanks in advance.
I just got my second shipment of redline from larry at dirty parts. I'm getting ready to do my 30k service, so I am replacing all the driveline fluids again. I ordered:
3 quarts of Mt90 synthetic gear oil for my MT6 (had a quart leftover)
5 quarts of 75w90 synthetic gear oil
