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!

My check engine light went on and the mechanic tested found it to be the CAT, i saw a forum someplace and they suggested Berryman’s B12. Soon as I added it to a full tank in my Honda check engine light off in 2 days.
I had a harder time with the 2000 Miata. I added the B12 and my car kept firing randomly which caused me to remain wherever the heck I was until it took pity on me and started. I waited for another fill up and added more. So I get to a mechanic and he says I need a $700 new CAT. My car sat in that lot not starting for over 1/2 hr. Finally it started, I get on the highway and couldn’t get it past 40mph. I pulled over and revved the engine for under a minute and pulled onto the highway with a brand new race car. I’m waiting and waiting for the 60 to get here to clean it all up. Instead of a new $700 CAT cost me $4 for a can of cleaner.

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!

Several years ago while working at a gas station a guy came in with his car smoking and limping along. Glen, the owner, told him that it needed a valve job and would cost a couple hundred bucks. The guy said something like, “OK, I don’t care, just fix it”.

The guy left and Glen, the station owner, parked it at the far corner of the station lot and poured in two cans of Berryman’s Chemtool into the oil and another can into the gas tank. He let that car sit out there idling for about three or four hours. It smoked like a burning tire for quite some time. He shut it off, changed the oil and filter and I took it for a test drive …. ran smooth as silk.
He then steam cleaned the engine, painted the heads and valve covers and charged the guy for the valve job.

Berryman Tire Sealant is a great product! It is hard to find in the gallon form in East Texas, but searched all over and found it at Carquest Auto Parts store in Lufkin, TX. Works better than Slime in your ATV’s.

Hello
I recently bought a tractor from the 50’s and as soon as I got it home I noticed I had a tire leaking, and it would be $275 to have someone come put a tube in it. I asked around if there were any good tire sealants that were up to the task and basically got told by everyone that they are a waste of your time and money. Well….I’m stubborn and I don’t always listen to others, so, I did a little online research and decided I wanted to try your product. I bought a gallon from a farm store and pumped it in the tire. As I was airing the tire up I could hear the leak and then it stopped just like that! It’s been a week, I’ve been using the tractor and it’s holding pressure just fine. Thanks for a great product!

I used Chem Dip today to clean the CRAB on my Farmall 450 tractor and now it runs great Before today the tractor would not run unless it was at full choke,I had rebuilt it but only used spray cleaner at that time. Submersion cleaned everything completely and now it runs perfectly.
