The other one is Amsoil sell gallons and quarts of 75w-90 api/gl-4 (MTG) Prices vary and its a full syn. If you have a GM store check part # 12346190. This is a GL-4 BUT might have friction adders. Try tightening the bolts on the tail shaft housing, this may top the leak depending if it's a gasket or rtv leaking. Happy holiday Rick L. |
Rick, I have actually called Redline, they recommend the 75w-90 NS(non slippery) for the Toploader, it is crated GL5 but he said that was closest to the the EP
oil that was OE in the Toploader. Also has no friction modifier at all. Another option was Redline 75w-90 MT90 this is GL4. Problem is, they are both
synthetic and as I have stated, I have read and heard to stay away from
synthetic in the Toploader.
I have made sure the bolts were tight, made no differance. Would you happen to know the Torque spec on these?
Happy Thanksgiving to you too...Dave
