Chevron Techron High Mileage Fuel System Cleaner, 12 oz, Pack of 6

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. 🚗⛽✨

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 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.

This is "good stuff". Both cars have noticeable improvement when passing other cars.

There is no alternate universe where you can test your vehicle's performance over the years using this product, versus not using it. But as my car passes the 130,000 mile mark I feel the need to do as much as possible to keep it running smoothly.While there is no single standardized, independent "seal" from a third-party testing agency (like the EPA or an independent lab) widely published for public viewing, the formula relies heavily on Chevron's proprietary Polyether Amine (PEA) technology. Independent mechanical testing and user feedback provide robust evidence of its effectiveness.Automotive experts and mechanics have conducted before-and-after endoscopic testing on high-mileage engines. They verified that a single treatment of Techron High Mileage Fuel System Cleaner significantly removes carbon crud from combustion chambers, cylinder heads, and intake valves.Product reviewers consistently report reduced engine hesitation, improved idling, and restorative fuel economy (often 2-4 MPG gains). Experts on enthusiast forums frequently discuss the base chemistry. Users and mechanics universally advise applying one bottle to a near-empty tank, then filling completely, typically doing so every 3,000 to 5,000 miles.

Stops engine ringing/dieseling at low to medium rpm in 260,000+ mile Toyota Sienna. Much cheaper and easier than replacing the still original fuel injectors.

The only engine /gas additive I recommend!I drive a Kia optima ‘18 and it’s at 156,000 miles only because I use this product along with AT 205 liquid polymer seal! It gives life to reduce internal engine wear and it improves the efficiency! This helps the carbon build up on my direct inject engine. Not too expensive and recommended to use at each oil change at about 3500- 5000 miles mine is an engine oil burner soo I change my oil more frequently!The only additive you need if you drive a gdi car!

The very best!
