Check engine light on (O2 sensor)
I had my check engine light come on and typically its the O2 sensor. I used this product and saved the cost of replacing the the O2 sensor ($90.00)and bam, light is gone and restored power back. Great product and little cost to clean fuel system. If light doesn't go out you didn't hurt anything and you spent [$] bucks.

As good as any competitor for cleaning injectors
B12 is comparatively a bargain since the car owner will not have to take the car to the mechanic for regular cleaning of the fuel system. The fuel cleaner should clean the area around the fuel injector aperture. This ensures the spray pattern is maximized for increased fuel mixture, therefore may increase average gas mileage. This fuel cleaner comes with 16 oz cans that are easy to open with no tools required except for a small fuel funnel to protect your paint. This pint of solvent will melt anything it stays in contact with, not only your fuel residue, but your paint as well. Instructions are printed on the can. Wash it off with soap and water if you spill it on your car. The Berryman B-12 chemtool is one of the best fuel cleaners in the market and might clean all the water and carbon deposits that could keep your vehicle from functioning properly.

This Stuff Works
Verified Buyer -
I decided to try this having used SeaFoam and seeing/feeling no real difference. After one tank, my car had smoother acceleration; idled nicer; and saw a bit of an increase in mileage. It felt like my car had renewed life. Will be a main product for my car.

Poured it in the tank before filling up. Just did an oil change and throttle body cleaner as well as sea foam in the intake and Marvel Mystery Oil in the crankcase. Car runs smoother but did a few things at one time.
Bottom Line No, I would not recommend to a friend

Very Strong cleaner
Berryman's B12 is really powerful. Open the can and take a whiff and you know it is not just some watered down kerosene BS like a lot of other injector cleaners. I used it on a shop towel to clean the throttle plate on my 09 Mazda5 and the varnish and gum literally melted away. I put the rest in the fuel tank and noticed within 100 miles that the car idled smoother and the jumpiness off idle was gone (throttle plate was definitely sticking). I also used some in the garage as a paint stripper- I was spray painting and had a bad drip, I didn't have any real paint thinner so I just used a dab of this stuff on a clean rag and it took the paint right off the part! Very impressed- I think most injector cleaners are a waste of money, but this stuff is basically heavy solvent. I think it would be overkill to use it more than 2-3 times a year though, being that it's so caustic.
Bottom Line Yes, I would recommend to a friend
