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!

Average cleaner

I haven't noticed much of a difference. I bought 2 more to see if you need to use this a few times before getting any serious results

            I used Lucas gas treatment and in one tank of use the Fuel Level Sender became unreliable. Gave very low reading. I drove 500 miles and no improvement.
            This product cleaned the senser in one tank. As an example my car has display that indicated "Miles To Empty" Before the Lucas the miles driven plus miles to empty would add up to 325 miles. After the lucas it added upto 200 miles. I was not sure if I could not get gas into the tank to filled level (Gauge only went to 3/4 )or it was the sender. After the Tectron the guage goes to full and the two readings add up to 325 miles again

              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.

                    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 .

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!

                              Happy to help you JoSaturn! Using this Fuel System Cleaner (Part No 65740) may help clear up some of the fuel system. If you are having a misfire a check engine light along with a trouble code may appear. If you do have a trouble code you can take your car to one of our stores to have the code read and that may help pin point what is causing the misfire if the fuel system cleaner does not clear up the misfire.

                              Happy to help with your question! This fuel system concentrate will not harm your turbos at all. This cleaner works on the fuel system. The turbo will be separate from it (air side), this may be come an issue as far as cleaning the induction system. So that you don't get very much carbon to go through the turbo you would honestly need to take off each part of the system and clean it while off the vehicle.

                              I'm happy to help, Jason! This Chevron Techron Concentrate Fuel System Cleaner (20 oz.) (Part No. 65740) is engineered for use at 1 oz. per gallon. You can use the cleaner in either way that you have described. Since you'll have a couple of gallons in the tank already, you may not want to add a full 20 gallons or you may want to add some additional Techron. Sometimes a second treatment is needed to achieve the full benefits.

                              If you would prefer to fill the gas tank on your 1999 Chevrolet Suburban, you could use two 20 oz. bottles and a 12 oz. bottle (Part No. 67740).

                            Will this work with my 2001 BMW 530i?
                            My fuel gauge is fluctuating a lot and maybe the float only needs a clean-up!

                              Happy to help you with your question Miba12! This fuel additive would not work for a situation like yours. This fuel system cleaner would help to clean out the fuel injectors and valves. If your fuel gauge is fluctuating it may possibly be an issue with your fuel pump. I would suggest having a certified mechanic have a look at your vehicle before you make additional purchases.

                              Hi TK, Hi JP, happy to help you! This part will work fine on your 2005 Ford 6.0L diesel engine. 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.

                            Can this product be used in conjunction with an octane booster? I've been using really cheap gas recently?

                              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.

                            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!

                              Hi Laura the Librarian, glad to assist you! 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.
