G50 limited slip growling on turns

[irobertson]

I just put my car back together and put Mobil Delvac in the G50.
It is shifting much better than it did with whatever was in it, however, I am noticing that on tight right hand turns I can hear the limited slip making a growling sound. I don't recall it doing this with the old gear lube.
Anyone notice the same thing with theirs?

Not to worry; Delvac contains no friction modifiers which helps make the LSD work better but you can get some clutch chatter in tight turns.

No harm, no foul.

Thanks Steve

What Steve said. If you don't track the car and aren't concerned with max performance there are LSD friction modifiers you can buy and add without having to change the oil again. You just add a few ounces and it makes it more slippery.

Does Mobil 1 75-90 contain the lsd additive? Is the additive necessary in the Delvac for street driving? Thanks.
