    Use Shell/BP in my car so I haven't noticed any difference in 5000 mi. maybe if I used lower quality gas it would make a difference.

    I use this to clean carbon from intake and valve by dripping into a central vacuum port with the engine running at 1500-2000 rpm. I use a special service tool for this.

          Comments about Sea Foam Motor Treatment for Gas and Diesel Engines (16 fl. oz.):

          Used in both of my 2002 Honda's with nearly immediate results. Noticed after first tank (one I added product to) of gas that my gas mileage increased in both vehicles. I track this with every fillup and went from 30 to 34 mpg on the civic and 20 to 23 on the Odyssey. On week 4 since last application and MPG is holding steady. I did not change where I purchased my fuel nor the Octane I used in either vehicle. I will be running this every month in both vehicles.

              I've usually put this in the gas to clean injectors and rid the gas of any water, but I put half a can in the oil before an oil change and felt that it loosened up some of the junk, making the new oil stay cleaner longer.

                This product appeared to work but you need to use a large volume of product to treat one tank of gas. Lucas oil lasts longer with a similar price

                  Have a ford 500 with 215000 mi was on a trip to florida and the engine light came on. Not knowing what to do I stopped at advanced auto he checked it with his handheld comp and said it was erratic idle. Then he told me about Sea Foam we put in a can and the light went out 2 days later and the car runs great with better fuel mileage.

                            No, the Sea Foam Motor Treatment for Gas and Diesel Engines should not be added to engine oil. Add 1 oz. Sea Foam Motor Treatment per gallon of gasoline. You can mix up to 2 oz. per gallon of gasoline if necessary. Mixing at less than two-thirds oz. per gallon will impair the effectiveness of Sea Foam.

                            SEA FOAM Motor Treatment is a 100% pure petroleum product that safely and effectively cleans internal fuel and oil system components, helping your gasoline or diesel engine run cleaner and more efficiently and will not harm engine components, seals, gaskets, catalytic converters or oxygen sensors. It liquefies gum and varnish deposits or internal engine contaminants, removing carbon deposits, freeing sticky valve lifters and rings, improving idle quality, pinging and hesitation problems. By using SEA FOAM to eliminate varnish and carbon buildup, mechanics can more accurately diagnose mechanical problems that may exist. As a fuel system additive, Sea Foam will clean carburetors, fuel injectors, clean carbon, gum and varnish deposits. For 2 Cycle and 4 Cycle Gasoline Engines, Diesel Engines or Rotary (Wankel) Engines. RECOMMENDED AVERAGE MIXTURE: a). Normal gasoline grades (including 10% and 15% ethanol blends)-1 oz. Sea Foam Motor Treatment per gallon of gasoline. b). Diesel fuel (including low sulfur and ultra-low sulfur blends)-1 oz. Sea Foam Motor Treatment per gallon of diesel fuel. Note: For above two grades a). and b). - SEA FOAM Can be mixed up to 2 oz. per gallon of fuel if necessary. Mixing at less than two-thirds oz. per gallon will impair the effectiveness of Sea Foam. c). For FACTORY-DESIGNED E-85 Fuel engines- 2 oz. Sea Foam Motor Treatment per gallon of gasoline. d). 2-cycle, gas/oil mixed fuel engines- 2 oz. Sea Foam Motor Treatment per gallon of gasoline. SPECIAL NOTE FOR OIL INJECTED ENGINES: Sea Foam Motor Treatment is ONLY added to the fuel in the above recommended concentrations. DO NOT pour Sea Foam Motor Treatment into the oil reserve tank for oil injection!. e). Fuel injector cleaning machines in a controlled environment use Sea Foam Motor Treatment as their safe cleaning agent mixed with gasoline or ethanol blend at a ratio of 50% gasoline or ethanol blend & 50% Sea Foam Motor Treatment.

                            A:

                            After warming up your engine. Keep the engine running at a high idle and locate either the PCV valve or the brake booster vacuum line. Choose which one you'd like to use and disconnect it. Using the PCV valve pour about 1/3 of the can in. If you use the vacuum line, pour 1/3 of the can into a container and then use the vacuum line to suck it out of the cup. If the engine stalls before you get it in, try sucking the fluid in slower. You may want to cover part of the line with a finger. When you have 1/3 of the can in the car turn off the engine. Pour 1/3 can of Seafoam into your fuel tank. Pour 1/3 can of Seafoam into your oil via the crankcase. Wait about 5-15 minutes. Start the engine back up. You may need to give it a little gas to keep it from stalling. Expect to see a fair amount of smoke, so you'll want good ventilation. Idle your car for a few minutes and then take it for a drive. Expect to change your oil in the next few hundred miles. Seafoam is not for long term use in the oil.

                            If your exhaust is "dirty" chances are your burning oil or have excessive carbon output due too an over rich fuel mixture. Fix those problems & the exhaust should clean up on it's own, unless the converter has been compromised. You can't "clean" a trans without a flush & you should change the filter too as well as drain the torqconverter. If you have a shop flush it with a machine make sure they change the filter too. Most don't & say it isn't needed, but when you change the eng. oil & don't change the filter you pump the dirt right back in not to mention a restricted flow that could cause slow shifting or even slipage. If your trans has a lot of miles on it, 60 to 70 thousand miles, I wouldn't reckomend changing the fluild at all. It may just go out completely. If you are experiancing minor slipage or slightly erractic shifting drain about a qt of fluid and add Trans X.In the least it's a "kill or cure" shot, but worth the risk.

                          i think my suzuki high pressure fuel pump is stuck. How can I use sea foam before taking to the shop, i.e., can I mix say clean gas 4 parts to 1 part sea foam for initial cleaning?
