Techron Fuel Injector Cleaner, 12 oz, Pack of 1

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.

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

Not as good as the concentrate plus but less expensive. I like to let this and similar product get sucked thru the brake line directly in the combustion chamber to hit carbon deposits, cylinder chamber, plugs and injectors rather than mixed with fuel and pulled thru the system. I wouldn't do this repeatedly too much but once every 3-5k miles is a great idea, especially if you have direct inject (GDI).

Good and uses a lot

PEA is a must for a top job in injector cleaning. Yes I usually use other cheaper things that work almost as well. I have one vehicle that's doing so much better with what I've done with it, that I'm stepping it up a few more notches. Yes, it's worth it.

Works great

Ordered before and was good. This time came in grey bottles with Spanish directions. Prod date was 07/2021 so old stock. Chevron says shelf life of 60 month so only five months left. Not good to get old stock.

arrived in a timely fashion and in good condition
