Anyone have any opinions on Red line gear lube? I read really good things on it and heard some others that have used it claim in made their rear end quieter over other brands. Also I see a lot of people using 75w140. Is this preferred over say 75w90?
I used 75W140 as it was recommended in the Ford/Shelby owners supplement/manual.
I see the early cars show 75W140 and later cars..at least 13-14 models show 75W85.
When I watched this video, I was blown away! I had no idea this is what the oil actually does. It makes sense now why the cover is shaped the way it is, and how an aluminum version with cooling fins would actually be a great upgrade!
