Found it for $55/gal on Amazon. It said in description 70w80 and also in other places 75w80 so I called redline and it's the same thing the tech said. Good to know.

I will do both my mirages and let you all know when it's done and my take on it.


Here is a link to the quart bottle as well: Red Line (50204) SAE 75W80 API GL-4 Manual Transmission and Transaxle Lubricant - 1 Quart
