Why not use multigrade? 120-130 1967


I put mobil 1 15-50 in my M400. I drove it around for
a couple months, and the shifting problems I had with it
didn't get better. I pulled out the oil and put in some
mobil 1 gear oil. The 15-50 motor oil had lots of brass
in it and there was also some metal on the drain plug
magnet. I didn't flush out the transmission prior to
putting in the new oil, but I recon that lots of that brass
and those filings were new and caused by the 15-50.

Weirdly, my M400 is dead silent on the road, it is just
a bit stiff going into first sometimes (this mostly went
away by overfilling the transmission with the gear oil).
