Hi guys, I am looking for the right Red Line oil for my differential. My Miata is a model 90 with the standard differential (NO limited slip). What's the right stuff to go: 75W90 or 75W90NS? Thanks, Ralf P.S.: BTW, just subscribed to the mailing list - hope to get tons of good tips... P.P.S.: Another question: Did anybody observe an increased fuel consumption after changing the ignition timing? If not, are there any other drawbacks?
