Fantastic item. Works as it should. Stinky. Beware when working outdoors near wasps nests. They will attack. lol

No more Ford power steering whine. No more shutter on a Hyundai transmission. I've purchased this product a few times. Use the while bottle for trans or diffs, everywhere else you can use sparingly. Highly reccomend... its magic in a bottle. Just DON'T smell it... worst smell ever that lingers

I tried so many,but non of any didn't work as good as this one . My LSD diff locks so well and quickly ,I never saw something as effective as this one

The product has a really obnoxious odor, however it really works! The gear oil I used had friction modifier in it but didn't correct the grabbing/ locking in the limited slip differential. One 4oz. bottle of the Ford friction modifier fixed 90 percent of the issues inside of 10 miles! After doing some figure 8s in a parking lot I suspect all grabbing will be gone.
