Rear diff fluid with ls additive in an open rear end???
I am looking at servicing my rear and front differentials. The only fluid I can find in 75x140 is Royal Purple (I know, there is a different weight for the front). The catch is, the RP fluid I am looking at has the limited slip additive. Will this be OK or will it mess up my open rear/front differentials. Thanks!
