I have used B-12 for over 20 years on my motorcycles, lawnmowers and anything else that needs a little help getting started and cleaned.

I started using Berryman B-12 Chemtool about six months ago. I find my engine runs smoother and gas mileage has gotten a lot better. I will continue to use this product.

I used B-12 in all four of my Chevy Astro Vans! The lowest mileage on any of them has been 300 thousand plus. B-12 is great.

After using B-12 Chemtool® Total Fuel System Cleaner my car ran like a fine tuned machine again. B-12 Chemtool® is great.

Berryman Products have proven to be a class act in maximizing performance, starting and saving on gas mileage. I have noticed a cruising speed, acceleration and overall car performance from using the B-12 product. As a direct result of my car’s performance, I have gotten 15 of my close friends to use the B-12 with all excellent feedback. I’ll keep getting people to use this product.
