I just wanted to say wow!!! I purchased a quart of this product put it in my new truck with 25,000 miles on it and noticed a big improvement in acceleration. I told my friends about it and put some in their trucks with 150,000 and 90,000 miles on them, they called me at work and ask "what the heck is in that stuff it runs and pulls like it was brand new" I have since given out 6 quarts as gifts!!! So I really just wanted to say THANK YOU and when will I get my selling bonus???
