I was wondering if any one else has tried this! I have a posi in my 67 vert. When I bought it the rear end popped bad when turning. I bought the expensive GM additive and the popping went away. I change rear gears and added new oil. You guessed it the popping returned. Just for the heck of it, or because I pinch pennies, I used a grease suction gun and removed about two onces. I then replaced it with Marvel Mystery Oil. To my pleasure the posi popping went away. Any comments?
