Features:

  • Cleans, restores, protects the entire fuel system (fuel injectors, carburetors, intake valves and combustion chambers)
  • Restores: lost power, acceleration, lost fuel economy, and operation of the fuel gauge sensor
  • Reduces: rough idle, engine surge, hesitation, and spark plug fouling
  • Improves: cold start performance, and fuel stability for up to one year
  • Automobiles and trucks use every 3,000 miles or at your next oil change. All other gasoline engines use as needed (motorcycles, dirt bikes, boats, ATVs, RVs, water craft, lawn care, etc.)

I run old garbage so I buy these six pack at a time

When your a cheap bastard and run old garbage, keeping the mileage somewhat respectable is key. Techron does that. Pop a bottle in at 1/8-1/4 tank, run it down and fill a fresh tank full and add another. Say hello to your aunty for me.

Essential for reviving a long-unused BMW

I was lucky enough to happen upon a cream-puff BMW 3 series, garaged, one owner, rarely driven in last 7 years. I wondered if I was buying a ticking time bomb, since it sat for so long. Had the dealership check it, change the oil and brake fluids, air filters, etc. But my local BWM-trained mechanic told me to put Chevron Techron in the gas tank before driving it around to clear the fuel line of sediment and gunk. I did so, drove off the stale gas, refueled and a month later, added another quart. It's running like a top. So glad I got this advice.

This is the concentrated version of Techron - Techron Fuel Injector Cleaner is the lower concentration

This is the stuff, the real concentrated stuff. The version labeled 'Techron Fuel Injector Cleaner', which is for example what Costco sells, is the same stuff, just a much lower concentration. If you are having fuel system problems, and think Techron might cure it, you want this concentration. The other version is better suited for regular use to try and prevent problems, but I still prefer this version for that task.

Seems to be more than a placebo! I recommend!

I purchased this right after I changed the spark plugs on my car. The spark plugs were a huge improvement on their own, but I wanted to clean out some of the carbon in my engine as I had noticed a bit of build up on the old spark plugs. I poured this into my gas tank right before filling it up as the directions indicated and by the time my car needed to be filled again it seemed to be running better than ever. I bought my car used, and the engine seems to be running better, cleaner, and more powerfully, than when I got it. A lot of that is from the high end spark plugs I added, but the carbon cleaning that this introduced served it purpose in maintaining my vehicle.

Fuel gauge works now !!!

Fuel gauge in GMC Envoy stopped working. Followed the directions and dumped it into a fresh tank of gas when I filled up. After about a week the fuel gauge started working again. Seems to do what it claims. Thanks!!

does make a differece

I have a Mazda Miata with 50,000 miles on it. I use premium GAS, I noticed the engine is not as smooth as I would like it . so read some of the reviews here and decided to use Techron anyway even if I use premium gas. after the first bottle, I already notice a smoother engine, I plan to use another one before I take it for an oil change

Fixed my problem after one day

I have a 2008 Nissan Sentra with almost 150k miles, the check engine soon light came on and after using a reader said it may be the catalytic convertor. When I brought it to the shop they told me if it was the cat to just drive it until it starts acting up because they are expensive. I bought this just to see what would happen. I followed the directions and the next day the light went off by itself. I haven't had any major problems so cant say if it is acting better but I'm very relieved that the sensor is no longer showing.

Works for what it’s supposed to do. Please read below!

Man the more I read reviews on here the more I have to laugh at how stupid the world has become. The first thing you need to understand as if it wasn’t spelled out enough is that this is NOT an engine cleaning product in any way shape or form. People mentioning that it hasn’t fixed carbon buildup in their engines clearly don’t know what this is for. As it’s mixed with your fuel and sprayed through your fuel injectors into the carburetor where it literally explodes it will never ever ever be in a position to clean your engine of carbon buildup. It won’t fix a car with major mechanical issues as I get the feeling a lot of people think it will and as for gas mileage, the cleanliness of your engine (which this doesn’t fix) is the single biggest determining factor in that (crap in your engine reduces space around the pistons and the chambers and affects compression ratio etc etc). This stuffs primary function is in particular cleaning your little fuel injectors which spray fuel over the carburetor head. I have no reason to believe it doesn’t do this. Now if one of your injectors is old and faulty - no it won’t fix it. If, there is mild buildup of crap in the injector head or opening it most probably will remove it - same way draino will clean your pipes but won’t fix a broken one. Simple? Got it? In terms of what I actually felt with my car? A little extra beef in the pickup - it hasn’t turned my RAV4 into a Ferrari, but I have felt a little uptick in pickup. This would seem consistent with some freshly cleaned fuel injectors probably being a fraction more efficient with their job of spraying fuel. So for goodness sake don’t read and believe the jilted claims of people here pissed off that a $20 bottle of refined fuel hasn’t fixed 2Gs worth of engine issues. This stuff is fine and some regular use will stop you ever having to fork out $250 for a mechanic to clean your fuel injectors if they ever got so gunked up. Cheers.

This product actually works for my car!!!

I bought this in September and used it in my 2010 Honda Odyssey right away (at the gas station) just before filling up the tank. Soon after adding this product we noticed significant changes in the vehicle. Below are few things we have noticed: 1.Engine ran so much smoother all of a sudden; similar to what one would experience after a fresh oil change but much better. 2. Significant improvement in the vehicle speed pickup as it was accelerating much better. 3. Slight improvement in fuel efficiency. I noticed an improvement of 11 miles per tank in my first ever use. Additional info: In my research I found that this is the concentrated mixture of the same additive called Techron that is found in the Chevron gas which is a top tier gas. Most auto forums I follow have advised to use this twice a year for the older vehicles and once a year for newer vehicles just before the oil change; too much can adversely affect the fuel lines/parts so in moderation. Always use top tier gas in your cars which has all those fuel additives. I personally prefer Costco for the fuel savings and it being a top-tier gas in most places if not all. Overall this product works for me and my cars that I ordered more for the later part of the year. You cannot go wrong to try it once especially in those older cars that run rough, sluggish and need a performance boost as this product cleans the internal moving engine parts which are essential for the engine's health in the long run.

Good price - read directions before using.

I have no idea whether this works or not because it is a preventative, but it is a whole lot less expensive that buying it at the dealer. Dealer recommends it at regular intervals if most of your mileage is city driving. Please note - read the instructions. I used STP and other similar products in my very old car, and it always said to use with a full tank of gas, so I almost did that in my new car without reading the label. This says to pour it in the tank when it is empty and then fill it up. I guess that makes it more concentrated because it doesn't mix through all of the gas in the tank - only what is close to the bottom?
