    Used it with Mobil One synthetic on my 2016 Challenger and it finally quieted the beast down....

    Many vehicles need this, check if your project requires it. I use it when necessary and it is a great additive.

    I bought this for a 2020 Ram 1500 classic. The additive seems to work but my rear end still makes an ever so slight noise upon sharp turns when accelerating, and when its cold. Now when I say it makes a noise you have to really listen for it and it only last 1 or 2seconds then its over with. And from what I have read this is a normal occurance for this type limited slip rear end. I dont remember it making the noise before the oil change, but I wasnt listening for it either, and after the oil change I was listening for it. So Im going to say its fine. The noise hasnt got any worse, and doesnt do it regularly.

    I use this and 3 quarts of Mobil1 75w90 LS gear oil in my 2002 Tundra. Without this additive, the LS clutches will chatter.
