I recently changed my rear diff fluid using mainly amsioil 75-140 but was a bit short so I topped it off with a synthetic blend 75-90 fluid to make up the difference. Probably only used 2-300 ml of the semi syn fluid and almost 2 courts of the amsoil. I initially didn't think it would make a difference but of course now I am worriied the two fluids may not be compatible with each other. The amsoil site states their fluid is compatible with all conventional and synthetic fluids, but I am still a bit concerned. What do you guys think?
