Chevron Techron Fuel Injection Cleaner - 12 oz, (Pack of 6)

Been using these for years now, I bought a 2020 chevy silverado in 22' I been using these since day one. Never gave me any problems I always do a oil change and put 2 of them in one tank. Every 5k miles as part of my oil service. One time I drove 500 miles in one tank. I have a 5.3l v8 with 33x12.5r20. So for me thats very impressive fuel mileage for wide tires.

Best injector cleaner on the market. Did research and bought this. I'm disabled and my mom is 89. We both had new plugs and wires replaced. My car still idled rough. Sometimes my mom's caravan was slow to start. We both had other extensive work done. We both fill up about every other month. Never driving more than a few miles at a time. I put a bottle of this in my car with about 6 gallons of fuel left. Put a bottle in my mom's van with about 10 gallons left. We both drove a few times with concentrated levels before filling up. My idle is no longer rough and have more power. My mom's van starts right away. I went to AutoZone and got two bottles of Chevron Techron fuel system cleaner. More expensive but I believe in this product. Google praised it. Now I am a believer. If you know anyone that doesn't drive much this could save you money in the shop. We both spent money on parts that didn't fix the problem. Ethanol is the problem.

Good brand, added a couple of times and mileage went up and the engine smoothed out with a little more power, wish I knew about this product a long time ago

Used the two bottles already on my two vehicles. Works great!

Had a rough running engine and then added this to an empty tank and refueled. [I had been throwing internal engine codes] Hard to tell how much of a difference it made but definitely appeared to do something. Still need another reset and see if the codes come back, but I think it was a good first step. The price here was good, and it was simple to use. My father is a mechanic and swears by it. I am not convinced it will fix the problem but am will to keep throwing it in every couple tanks. I wish I would have gotten the multipack.
