### ⭐⭐⭐⭐⭐ Works

Works as expected

### ⭐⭐⭐⭐⭐ Price

STP is always a good product.

### ⭐⭐⭐⭐ Good, but Didn't Fix
*by A***G on September 27, 2019*

I think my Ranger has a valve cover leak, but I wasn't sure how big it was so this was my first attempt at trying to fix it out of curiosity. The leak must be too big, cause even after an oil change the leak got bigger as well, so I figured I probably should have left the old oil in there, but I had a reason to change it anyways, so now I go on to fix the leak with new gaskets. Probably did some good as I love this product otherwise! Edit: Upon further inspection, no more leaks after doing the valve cover gaskets, and everything seems to be good! This stuff should now help everything last.
