    Valvoline 50w-90 High-Performance? Diff oil help?

    I see people running 75w-90 as well as 75-140. Local auto parts store has 80-90 and 85-140. Also looking at Valvoline High Performance since Royal Purp is 20 a qrt. Anyone tried this and it not blow a diff apart?

    Going to pull the diff cover off since PO destroyed the drain bolt plus I have the Condor diff busing to throw in, main question is high temp rtv good enough since I can't find a gasket locally???

Maybe the species that communicate with each other through a filter of your comfort are less evolved that the ones that just communicate? Maybe your problems are your own to deal with and maybe the public giving a shit about your feelings is a one way ticket to extinction.

      I meant 80-90 in the Title.

      Also, the diff cover can be removed with the diff still attached correct>??

          Not sure about the cover... but I've been running Redline 75w90 NS since I got the car, no issues.

              RTV (ultrablack permatex) is just fine.

              You can do it in the car, but it's hard to get/keep things clean and keep the RTV from
              getting wiped off when you weasel the cover back on- you end up having to bend
              the back tab back some.

              I use the heavy weight in the street cars, and the lighter weight in the race car.
              For no real apparent reasons... and it seems to work fine.
