Differental Fluid Question
I Have A 75 Vette And Am Going To Change The Differnetal Fluid And Add The Gm Additive However I Have To Order The Additive And Differental Gasket And I Have An Event To Attend This Weekend. My Fluid Is Low Due To A Leaking Differental Gasket. I Have Some Valvoline 80-90 Fluid And Some Crc Additive For Posi-limited Slip Can I Use This Stuff
This Weekend? My Rear End Is Limited Slip And It Reads Limited Slip Fluid Only. Will The Crc Posi-limited Slip Additive Hurt It?

If the Crc stuff meets the GM spec it should work fine. Just by it's title it sounds like the right stuff. You shouldn't have any problems. The tag on the diff. housing just means you have to use the additive.
