Chevron Techron High Mileage Fuel System Cleaner, 12 oz, Pack of 1

The Chevron Techron High Mileage Fuel System Cleaner works exactly as advertised. After using it, my engine runs smoother and idles more quietly, and I’ve noticed better acceleration and fuel efficiency. It’s easy to use—just pour it into the gas tank—and one bottle goes a long way. Perfect for keeping older vehicles in good shape. A solid product I’ll keep using regularly. 🚗⛽✨

Well known product. Works, all my cars run better with it. Competitive pricing.

I'm a vehicle additives freak. But my shop said I was wasting money on what I was purchasing. They suggested Techron. Noticed a BIG difference after one tank. I have a 2000 Jeep Wrangler that's been turned overlander. Lots of extra weight. But after using this, wow! Power galore. Mileage, so far, up 2mpg. Not earth shattering, but up.

This is a high quality fuel cleaner. I use this in my Ford 2.0 ecoboost engine which has direct fuel injection. I believe this keeps the valves clean.

I've been using Chevron Techron High Mileage Fuel Additive regularly in my 2019 Volvo S90 Plug-In Hybrid, and it's definitely earned a spot in my maintenance routine. While hybrids don’t rely on the combustion engine as heavily, I’ve found that a dose of Techron every few thousand miles helps keep the fuel system running smoothly, especially when I switch from electric to gas. Pros: Engine runs smoother and feels more responsive after use Helps maintain fuel system cleanliness, especially important for high-mileage engines Easy to pour, good packaging, and widely available Cons: I didn’t see a dramatic increase in MPG, just a slight improvement It’s not cheap if you're using it regularly, but I consider it preventative maintenance Overall, it’s a solid product that does what it claims—cleaning injectors and helping reduce hesitation or rough idling. I’ve noticed less engine noise and more consistent performance since incorporating it into my maintenance schedule. Not magic in a bottle, but a worthy addition for any high-mileage vehicle. Would definitely recommend, especially for hybrid owners who want to protect the fuel system during infrequent engine use.

I bought this for my 1997 F-150 with 156,000 miles that was running a bit rough. After using this product on two fill ups, my engine is running smoothly. I WATCHED youtube videos on the product. It works.

Used it on my Tacoma and it's been running smoothly!

This is the gold standard of fuel system cleaners. I am a mechanic. I swear by this stuff. It uses higher amounts of PEA than other fuel system cleaners. If you don’t believe me, just look up The Motor Oil Geek on YouTube and listen to his testimonial. This is an American product that outperforms the rest, including Red Line or Liqui Moly. Red Line is also a great product. But this is cheaper, and better. You only need to add this to your vehicle’s gas tank every 3,000 miles, so it isn’t expensive if you consider that. I personally do add it to the tank more often (when finances allow) because of the increased fuel economy I notice. I’d you want to keep your vehicle running in top shape in these tough economic times, look no further than Chevron.
