Question(s) for Innovator
The owner manual does not say what oil shoud be used, I did a search and everything points to a 75w90 oil, about 2.9 quarts of it, but nobody says anything about GL-4 or GL-5. Most gearboxes use GL-4, unless high pressure between teeth require GL-5 (like most rear differentials), but the the high pressure additives found in GL-5 are not syncro friendly, as they are probably made of bronze, so I am really split here. I really need to try a different oil (Red Line) because my second gear is so sloppy it takes away much of the pleasure of driving this car.
