No not Lysergic acid diethylamide! LOL 😂
Q: How much limited slip differential additive? I have read elsewhere to put 1 bottle of oil in, then whole bottle of additive, then top up with second bottle of oil, to drain hole. Can anyone advise please. Would really appreciate OUR members input. Thanks Steve.

Diff Lube and Diff Additive
4oz GM Additive x1
32oz GM Lube x 2
You need all the Additive, but the diff will not hold all the quantity of Lube
Put the Additive in and then use one and a part bottles of lube up to the Fill hole
And then Shake but do not Stir.

When I had my diff rebuilt, Gary Ramardi (in the US) recommended two bottles of additive, so that's what we added. I put that in first, then added the GM oil to fill.

Than, take the car to a big open space and do a few (about 12) gentles figures of eight, to get the additive fully worked into the clutches.
