What would be the best manual transmission oil for a 1993 G20? Also, how much will I need?
I ordered Motul Gear 300 expecting that it is a gl4. They sent me a gl5 and I called them and asked them to send me a gl4 and the person looked several times and came back with an answer of "thats the only kind of Motul Gear 300 we carry." So, according to him (didn't get his name) I assume thats all they carry. BTW, a gl5 fluid will list gl4 also since it exceeds it.<font face="Verdana, Arial" size="2">Their web page lists two and one is a 75W90 GL4. Or is that just one product with two ratings??</font>
