What synthetic weights of oil can be used in the manual transmission, turret, and differential in my 91A? I went to Mobil 1 in the motor last week. Would 75W-90 do for all the above? Redline or something else? And if Redline, where might a guy find the stuff locally? This ought to be a long thread ;-) Thanks in advance!
