I will need to refill my 7 1/4 differential soon, and since it is a Sure-Grip I want to amke certain that the lube that goes in is going to be good for the plate clutches. The axle came from a '66 Dart. I recall back in the day, there was a lot of caution notes about using incompatible lubricants. I picked up a bottle of Castrol Hypoyle C gear oil which the part guy swore was OK. On the bottle it claims that it .."Meets the service fill requirements of conventional and limited-slip differentials."
My question is simply, do they know what they're talking about? Or has lube oil engineering gone that far since the last time I checked (about 30 years!)?
