I have a 1999 Dodge Status with 184K miles on it. I was considering replacing all of my fuel injectors as I had at least two of them barely working and I had rough idling and poor gas mileage (~10 MPG). I witnessed the HEST test and I decided to try the B-12 Chemtool ($4.99 at my local parts store). I put a can of it in my empty tank and then filled to a 1/2 tank with premium. Holy Cow!!! My injectors are all firing :) Yay!

this is a revised update by me on the continued use of using b12 chemtool in my gas tank. at every fill i use 4ozs in the 11.75 gal tank. i’ve noticed the following mileage increase – almost 4 miles, no hesitation & quicker start up. my kia rio 2008 runs as good as the day i bought it new. by the way i just turned 307,000 highway miles on it. i’m truly grateful for this wonderful product of yours.

I have several High Performance cars that sit in my garage and are only driven on weekends. I noticed my Porsche was making a coughing noise along with a slight backfire when I first started it up. After putting in a can of B-12 Chemtool fuel treatment within two weeks the problem was gone! The product is great and I highly recommend ot to anybody. I use for all my cars now for maintenace purposes.

The B-12 Chemtool additive is GREAT! My rototiller would not start, due to the additives Delaware mandates in our fuel. Using one ounce of B-12 and new gas, I’m back in the tilling business and ready for spring.

I have a 2006 Mitsubishi Lancer Evolution. The car is completely stocked and has about 35 thousand miles on it. I came across the B-12 Chemtool, and was talked into buying it. I tried it with absolutely zero expectations. Well, to put mildly, Wow! What a difference. My car had been suffering a low RPM detonation problem– I am talking normal driving right off the line. Within 25 miles of having a full 15 ounces in 14.5 gallons of fuel, the detonation was completely gone. My car had been detuning itself because of this problem for at least a year, and now all of the sudden I feel as if I have 50 more horsepower. I have gotten five other people to try it and everyone agrees that Chemtool is awesome.

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.

A little over a year ago, there was an acceleration/hesitation/stumbling issue with my wife’s ‘99 Blazer. Well, this is what has been changed out since from beginning to end: plugs, wires, distributor cap, MAF sensor, fuel filter, air filter, thermostat, coolant temp sensor, and finally, the ignition coil. I had completed all necessary oil changes at intervals, cleaned throttle body intake, flushed and refilled coolant. This has stumped me for some time and I have taken it to two different mechanics and they have told me to do all that you see above after doing diagnostics with no codes and pressure in all lines. Finally, it was my local auto parts shop guy that recommended me to stop using gas with Ethanol and use Berryman’s B-12 Chemtool Fuel Injector Cleaner for two weeks. Well, I must say that this stuff is magic in a bottle. I have been through Lucas, STP, Chevron, and all the names in the Walmart’s as a fuel additive. The first day, letting the gas run down in the tank, refilling with non Ethanol high test and using one bottle of the Berryman’s, and the car no longer has the issue. Thank you to not only all the people that recommend non Ethanol gas, but the clerk who recommended this product. The very first day running the car was noticeably different and now a few days later, my wife says there still is no problem. Looks like I would recommend this to everyone reading.

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.
