In preparation for getting the pinion leak fixed, I wanted to ask if there's any preferred diff fluids to use. I was looking at Amsoil Severe Gear, RP Max Gear, or possibly Redline Shockproof and leaning towards Amsoil.
And then I'm unsure on 75w90 vs 75w140. Most of the Cobra's time will be (spirited) street driving, but I would also like to survive the odd open track day.
