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.

    Comments about Berryman B-12 Chemtool® Carburetor Fuel Injector and Fuel System Cleaner (15 fl. oz.):

    B-12 is a great fuel system cleaner. I have used this product for years to clean carbs and fuel injected systems. This is great at eating up old gunk left behind from old/stale gas. I had a snow blower that didn't run for 2 years and had bad gas. Drained the tank. Poured about 1/3 bottle of B-12 let it sit for an hour then topped off with new gas. The snow blower started right up after that.

              I used this product along with Berkebile Oil Company 2+2 Instant Gum Cutter to clean the carbon deposit from the secondary air pump system on my 2005 BMW 545i. Took about an hour but it worked like magic. Combination of both products opened up all the ports. NO MORE P0491 P0492 ON MY CAR.

              I had tried Seafoam in the past but seafoam is not as strong and will not break away carbon. Dont waste your money on expensive stuff when they are not as potent.
