I had a engine that was surging and would stop running. I added B12 to five gallons of gas. With in a couple of days of running the machine it cleared up and now runs smoothly. I have tried many different additives. This is the only one I will ever use from now on.

This is Berryman's strongest cleaner in their lineup. It works incredibly well.

Ran this through my son's Focus platinum with an O2 code. I knew he hadn't cleaned the injection or fuel system. By the time he had run ½ of the tank (6 gallons) of fuel through the car the light went off and the car ran much much better. 1 ounce per gallon of fuel. Very impressive.

I actually purchased this to run through a 60+ year old tractor engine. It had been sitting for quite a while while I did some work on it (none of which was related to the fuel system or carbeurator. After the project was finished, everything worked fine for a few minutes, then the engine would sputter as if it wasn't getting any gas. This condition would be worse if I was running it at higher RPMs. This happened a few times and once even died but it started back up after a couple minutes. On a hunch, the easiest thing was to run some carb cleaner through it. I portioned it out to match the amount of fuel in the tank and then ran the engine hard for about 45 minutes. It ran perfectly without any sputters along the way. Did this really help? I don't know. What I do know is after I ran this through the carb, the problem I was having did not happen again.
