Sam

My grandson added a couple of ounces of B-12 to his 1997 Sea Doo that was stalling and hesitating. Amazing results in only about 5 minutes of run time on the water. I’ve never seen anything work so well; so fast.

I’ve used the Berryman B-12 Chemtool fuel system cleaner in my 70 year old 1947 Ford 8n Tractor for the past 7 years that I’ve owned it to keep it running rite. One bottle a season keeps my 8 N running like a champ whether I’m clearing snow from my driveway, mowing the grass or simply giving hay rides. Hunka B-12 really helps battle those ethanol Gremlins.

A friend bottled, boxed and shipped this product in S. CA in the 60’s. We already knew it was great as we used it to get seasonal equipment unvarnished and purring after being idle all off season. Later working in a garage it was our prime tune-up solvent for fuel systems. I have always used this product for any fuel system and will never look back. It’s the best! B-12 & Marvel – The Magic Team!

Hello,
My daughters 05 Mercury Sable 3.0 DOHC with 73k was running awful and showing multiple codes such as: p0430 / p0174 / p0316 /p0305 / p0306/. A local shop wanted to charge $600 to replace several parts. Knowing I had used STP injector cleaner a week or two before the car started acting up I didn’t think any more cleaner was necessary or would even help. I was about ready to give in and pay for the repairs to help her out when I seen your B12 ChemTool product at a local Meijer and decided to give it a try. After a couple several mile test drives it started to run like new! No more codes either! I’m so thrilled that your product worked so well I bought a few more bottles for preventive maintenance in my other vehicles. We are so relieved and grateful to avoid a costly and unnecessary repair. “Thank you!” really “Thank you!”

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!

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!

Been using it for years . First heard about it at the drag races. VEry surprised , and even made skeptical , by the great price. Price has managed to stay low throughout the years. Have tried many other expensive,even professional, products. This one always seems to work. Stopped wasting money , and started saving it instead. Used it countless times on cars and trucks , new and old. Have even argued with auto parts employees over it, when they try to sell me seafoam or STP (on sale). Ive even had one say that its too strong and will cause my seals to dry /crack……. Nver happened . I used it for the whole lifetime of my Nissan,as a fuel addititve , and as a solvent to clean my injectors directly through the intake. always felt the diffrence immediately. Never ever felt like i wasted my money and got robbed (unlike others). Never had no engine trouble. Sold it at 280000 miles going strong. Repaired the valve cover seal , my friend (long time mechanic)thought i had a rebuilt engine because it was so clean inside. I have amazed and made many other believers of friends, by helping them tune up/maintain there car using berryman b-12. First they are skeptical, think its too good to be true, waste of money. Once they experience the difference in power. Smooth idle. Car even starts and feels and sounds different. Ive had some older cars feel renewed instantly. Now everyone is constantly wanting to use it on there cars, or asking me how to do it again. They all want to know so they can help other people/themselves with there car maintinance. First and only mandatory , and consistent product on my list for tune up supplies. Other items can be substituted , But for Berryman there is no close substitute. Thanks to Berryman for offering such a quality product and keeping it affordable. Helps many people , especially when times are tough to keep there vehcles running great!
