NO BS! My 1987 Ford Ranger 5sp 2.3 efi Has been used to haul 2 adult horses, with trailer and 1/2 ton of hay thousands of miles up and down I5 over the years. I used it to pull my 2008 Freightliner around town when I accidently ran it out of fuel. I’ve delivered 2 ton loads of hay throughout western Washington, this truck has over 225k miles on it and I would drive it to Maine tomorrow without giving it a second thought.
My dad INSISTED I use Berrymans and ONLY Berrymans on my 1st car and in the last 40 years I’ve owned 4 Vehicles, the last being my Ranger, all super high milage and I’ve used only Berrymans products (and routine maintenance). Now I might be the luckiest car guy alive or… It might just be the 40 years of Berrymans products. Myself? I don’t believe in luck. Use Berrymans. It’s good stuff!

1999 Ford Ranger 3.0 with 168,000 miles. The truck had an issue where sometimes when I started it (cold), it would run rough and throw a misfire code. It progressively got worse to the point where it was happening practically every time I started it. I knew it couldn’t be the spark plugs because they were practically brand new with only about 5,000 miles on them. So, I decided to try an injector cleaner as my first troubleshooting step. I chose B12 Chemtool because it was cheap and I understood that it was one of the more powerful cleaners. After pouring the entire 15oz can into my tank and filling up, it only took about 10 or 20 miles before I noticed that the starting problem had gone away completely. I am honestly impressed enough that I wanted to submit my testimonial to this website because I hope this product is able to help others as it has helped me. I plan to use B12 Chemtool in all my cars routinely, say, every 30K miles to make sure the fuel system in clean to prevent this problem I had with the truck.

I tune up and repair small engine equipment as a hobby and source of extra revenue for neighbors, friends, and their referrals.
The other day I picked up a 7.25 HP lawnmower with a Briggs and Stratton motor that was completely locked up due to running out of oil.
I added B-12 to the Crank Case, and slowly turned the blade after letting the solvent work for 6 hours.
After finally freeing the blade completely around, I was able to start and run the mower with ONLY B-12 in the crank case.
I thought it was a gonner, but B-12 did the job!

1995 olds 88 3.8 L nock sensor problems causing 21 MPG. Now with B12 Chemtool I am at 29-31 MPG

Plain and simple, best stuff I’ve found. Best price hands down . Outperforms all others I’ve tried. Value can’t be beat. Never let me down . Never disappoints. Personally used it in over 20 cars, many repeatedly , with no adverse effects /damage to the vehicle. Great stuff. No B.S. Money well spent! Glad its going strong and is available in more places than ever, still for a hell of a price. Thanks Berryman again!
