I wanted to compliment you on your products. I’ve just purchased a bottle of B-12 Chemtool Fuel Treatment. I have two cars that have more than 200 thousand miles on each of them and I am a full believer that your products have helped them last this far. With future maintenance, which I will do with your product, they will last me another 100 thousand miles. Thank you and y’all are doing an outstanding job, and I will definitely recommend this to the people I know.
