It's about time to change the rear differential fluid on my 94 signal turbo supra, just want to know which one to use because I have heard mix of opinions on this one. mobil 1, redline, royal purple? what grade? thanks
i use the royal purple 75w and all is good here.after changeing my stock oil[sludge] and now using the rp75w it seems smoother and less draging like feeling.seems to me it reduced friction. but since my stcok gera oil was like sludge i now know why..
