Had a Service Fuel System Error code. Fuel Guage dropped to Empty & stayed there.
Used a double dose of Techron & it cleaned my Fuel Sending Unit. It supposedly gets gunked up on the fuel level contacts with Sulphur contained in fuels. A day later Guage came back & error cleared.

Is supposed to save my mileage.

Didn't notice any difference in fuel mileage. Dealer recommends adding, I think it is just a profit maker for the two.

      Comments about Chevron Techron Concentrate Fuel System Cleaner (12 oz.):

      I have a 1992 Chevy Truck that I drive once or twice a week in stop and go traffic. If it sits too long without running hard the throttle body injector malfunctions (runs rich). This truck has to withstand ethanol in the gas that attracts water into the fuel from the humid air. I use good gas but the only thing that fixes the problem of stalling and missing at idle (and it works within about 20 miles if you drive highway speeds and double the dosage)is Chevron Techroline.

      They add also it to fuel at their tank farms.It is backed by research done over 40 years by one of the largest oil companies on the planet.

      This will not fix bad plugs, wires, distributor cap, etc. I also change fuel filter once a year to get rid of water build up.

        way my car performs.

            Comments about Chevron Techron Concentrate Fuel System Cleaner (12 oz.):

            I use this product or one equal to it when I change oil, so I can be consistent and keep my fuel system clean. If you don't drive much you better use it more often. If you have two vehicles and drive one more than the other it will need cleaning more often especially if it sits for long periods. I retired in 1996 and worked less and fished more. When it got where I couldn't fish I almost stopped driving my 1989 Ford F150. First both fuel pumps F & R tanks went out. Got that fixed and it started missing and shaking. Still trying to clean my fuel system where it don't miss. The mechanic thinks it is the fuel injectors and should get better driving it more and use fuel injector cleaner. Never let your vehicle sit. If you don't use it sell it. Repair cost so far $275.00

                      The bottle says to add when near empty. Should I add the bottle to my fuel tank and then drive with it to fill up with gas (4 miles) away or should I add it to my fuel tank at the gas station, just prior to filling up. Which is recommended?

                        Hi MKFLA, happy to help you! The Chevron Techron Complete Fuel System Cleaner 12oz (Part No. 67740) is a premium fuel system cleaner trusted and recommended by many automakers to help restore lost fuel economy and performance. Its patented polyetheramine (PEA) technology is unsurpassed as cleaning deposits from intake valves, fuel injectors, and combustion chambers. It is safe and effective to use in all ethanol fuels, including flex fuel like E85. For further information, I would suggest that you contact the manufacturer directly at 1-800-822-5823 and they would be in a better position to help you.

                      I have a 2007 C230 Mercedes. My check engine light comes on and it recently misfired and the vehicle shutters when slowing down. Prior to the check engine light, I may have purchased a tank of bad gas. I took the vehicle to the dealership and they were unable to pinpoint the issue. If I were to drive out my gas and add the Techron and top off at another gas station could this possibly resolve my issue?

                        Hi Angel the Newbie, glad to serve you! If the check engine light is flashing, then it means your engine is misfiring. A solid light can mean anything from a loose/faulty gas cap to a transmission issue. This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present. In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. The code will tell you what may have caused the light to initially turn on. However, I would suggest that you take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.
