Today I Purchased 3 Quarts Of Synthetic Oil To Go In My 4:10 Rear End (75-140) Is There Another Additive That I Should Put In There??

Do the figure eights in a parking lot and if you feel the LSD catching, then get some DC additive and start with a half bottle. Then repeat the figure eights. I put Aimoil 75-140 in two years ago and added the half bottle, recently I added another 1/4 bottle. SNOKING

Also you may want to get one more quart mine took 3 1/2 with plus additive
