this stuff works
first used on a four banger that had developed a knock from running without water due to a broken hose in the arizona heat, and after fixing the hose, adding water, and regularly using the restore product, i put another 50,000+ miles on the car before selling it on many years later. i am convinced it has saved me thousands in repair bills and has extended the life of, and quieted tired and noisy motors. i now use it as a preventative in my antique cars with great success. it won't bring back the dead, but it'll often restore lost performance dues to wear.

This product is not as good as it once were.
I have used this product in the past and have had good luck with it. But I don't know if the formula changed or what but as I have looked at other people's reviews of this product is either a Love or hate. My situation is I use this product drove my vehicle and then I've been noticing the oil PSI indicator has been going lower and lower and lower to the point where was almost at zero I had to think what did I use and was this product I went back online to see the other negative reviews especially from Amazon and they are very true I had to drop the oil in my car with also adding a new filter and the PSI level went back up to normal. While draining the oil from my motor I noticed it was very thick. I don't know what is going on with this product but I really don't think it's the same as it once were.
