Prolongs engine wear

I’ve always used this product in truck engines. Now I’m using it in my car. It’s especially beneficial for the turbo that not only spins at a tremendous rate but also gets very hot.

Slick 50

I started using this years ago. I had an old car that drank oil. Once I forgot to check the oil, for about a month. When I check it, there was no oil in the engine. So I ran about, all that time, with just slick 50.Read full review

11 tanks full for the price of 10!

I have used this stuff before, it lived up to all that was claimed of it. Plus, added smoothness. Eleven tank fulls for the price of ten!
