For my 1970 Nova with 4 cylinders, I have used the same AC Delco limited slip lubricant twice in the past three years. The rear differential has 11 gears and is posi-traction. While I didn't notice any changes in the product, the old fishy smell I used to get from similar products I've used in the past was no longer present. As a result, I removed the differential cover and completely, rather than just draining the old oil through the fill/drain plug, drained my differential. My oil was Lucas Oil (LUC10043 80W-10 If you have to refill the differential, use 90) heavy duty gear oil. Our testing performed after the service did not indicate any grinding, which was expected given the Lucas product meets or exceeds GL5 grade oil. You will probably have problems mixing different gear oils if you have not drained your axle completely. Otherwise, you will likely have Thanks for your patience with my lengthy reply. I wish you the best of success
A differential that contains a limited slip or locking must be installed on the rear axle (only applicable to the rear axle). differential oil will never be a locker or limited slip, so just change it when you replace the oil in the front differential. As a result of changing an open differential with spider gears to an Auburn locker, I had to use this oil

As a result of my differential grinding, I was hearing a loud noise. It never occurred to me that this could On my Corvette, I thought the rear needed to be replaced. I was able to do it. The noise was gone almost immediately, and finally after about 3 days it was completely gone. My belief would not have been confirmed if I had not experienced it first hand. I wouldn't have tried it despite so many people telling me to if they hadn't told me about the Corvette forms.
Did not pour or smell like what I am used to. As a result of this, as well as the Valvoline gear old, the clutch packs in the 69 Chevelle Posi unit would lock up in low-speed When trying to turn off a stop sign, the car was shaking, crunching, and lurching as if something had been tossed into the As a result, I drained the fluid back out, it had been nasty after driving for 2. I then refilled it with a different brand of each fluid and my troubles went away. Just glad that it wasn't the rear end I just installed that was the problem. I don't know if it was the additive or the lubricant.
Although it may sound silly, it's because the fill plug on the differential is in a cramped place and I specifically bought this for the easy fill nozzle in the picture. You do not get a nozzle to fill it easily. The nozzle spout is why I chose this one over another. I know I can use tubing, a funnel, or put it in a different bottle and squeeze it in, but it one of the reasons I picked this one over another was the nozzle.
In my 98 GM Limited Slip, I had a chatter after using synthetic oil. Now, after using GM oil along with this, the chatter is gone.
For the last 40 years, I have been building posi differentials and the AC Delco has never failed to mitigate.
I find it amazing that 4 ounces of gear fluid would be such a great elixir of life out of 64 ounces of gear fluid. After studying chatter problems for two weeks, I decided to write one myself. Obviously shortly after my idiot mechanic had performed a bunch of 100K maintenance, while he was trying to isolate the problem. After a long time, I came on to limited slip. It was changed to a limited slip but not with the fluid. However, this stuff perked it up like a champ and all problems are now gone. The savings I achieved were at least $500 more than what I had paid in dealer fees. This is good stuff.
There is an old car that I have that has a "posi" The additive I use has never caused me a mechanical problem, and I have always used it.
