As a former service station owner who had at my disposal a full complement of engine analyzers, I relied exclusively on Chevron TECHRON to clean injectors and fuel systems. I can say with 100% accuracy that it works, with far too many documented cases of success and not so much as one failure. All results backed up with empirical data and complete before-and-after test results. BUY IT! USE IT! IT WORKS! A similar product which we used in carburetted engines was BERKEBILE 2+2 Gum Cutter and it too was excellent.
And if you're using cheap gas, you really need this!

No difference, but doesn't hurt.

I don't notice a difference after using it, but I'd still use it. It helps clean the fuel lines and injectors. I guess mine are clean enough. I tend to use it once...Read complete review

    On my 2011 Charger I was getting a Misfire. Car got an tune-up. Monroe Tech told me to get 2 of the Chevron 20oz and top off my tank. Kept getting the Misfire code 3 more time till tank was empty. One last clear of the code and tank was empty. I have yet to see the Misfire code again. So, Im a believer. Very Good Product.

      I have seen first hand before and after results using this Techron which is the only reason I continue to use it. Not saying others don't work, but I have seen this product work. I typically add a bottle every oil change or so... any more than that would be over kill personaly.

        This product was recommended by our mechanic. It's easy to use. Before you fill up your gas tank, making sure you're almost on empty, pour one bottle of this product in your gas tank and then fill with gas, preferably with Chevron gas. Increases gas mileage and cleans fuel injectors. We use a bottle every third fill up.Our van is a 2001 and has 220,000 mile on it.

          Comments about Chevron Techron Concentrate Fuel System Cleaner (20 oz.):

          I had always used BG 44-K with good results ,had trouble with my C5 Corvette fuel guage going out , came across the use of Techron in the forums . Techron cured the problem on 2 ocassions , I now use it on all my vehicles . Long story short I think Techron outperforms the BG 44K , not that the 44K didn't clean the fuel injectors well , but Techron has an additive that adresses Sulfur build-up on the electrical componets on fuel guage in - tank , I think due as result from not being driven regularly .

              Used this in all my vehicles and its helps maintain the smooth RPM's and keeps the gas milage high! When its on sale stock up,you won't be dissapointed!! If you have a sportbike use 1/3 of the 12oz bottle for every tankful and feel a better throttle response! Advance has the best sale when its BOGO so if you have multiple vehicles get a case!!! Be safe on the road from Shiftn Steel Sport Riderz!

                          I'm happy to help, Tom! Chevron Techron Concentrate Fuel System Cleaner (Part No. 65740) is able to be used in conjunction with an octane booster if you desire. The use of questionable quality gasoline can be concering and Techron is a great product for cleaning the fuel system in your vehicle 2006 Chrysler 300 Limited with the 3.5L V6. I have found that Chrysler recommends the use of 89 octane unleaded gasoline in your vehicle. If you are using 87 octane fuel and using an octane booster, you may be spending more on fuel and additives than is necessary.

                          The use of a Top Tier brand gasoline at 89 octane or higher can provide similar results with less cost per gallon. If your local fuel stations do not offer mid-grade (89 octane) gasoline, mixing premium and regular gasoline can help to provide fuel that is closer to 89 octane while reducing the need to purchase an additional product.

                      • Q:

                        My car has a 13 gallon tank. Is it safe to use the whole 20oz. bottle at once or should I just put part of it in? Will it really help increase my gas mileage (which has been going down as the car ages - it's a 10 yr. old Vibe), and make the sluggish acceleration better? Thanks!

One 20 ounce Chevron Techron Concentrate Fuel System Cleaner bottle treats up to 20 gallon tank and uses every 3,000 as part of a regular maintenance program. You can add 20 oz bottle in your 16 gallons tank and it will not hurt anything. This is a premium fuel system cleaner trusted and recommended by many major automakers to help restore lost fuel economy and performance.

                          Hi Rahman, glad to help you! This part should work fine on your 1999 Toyota Camry LE. It is designed for carbureted or fuel-injected spark ignition engines. This product can be used with diesel fuel in the light-duty indirect-injected diesel engines. It is not recommended for air-cooled 2-stroke engines.

                          Hi The Element Girl, glad to help you! This product is a premium fuel system cleaner trusted and recommended by many automakers to help restore lost fuel economy and performance. Its patented polyether amine (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.
