Techron High Mileage Fuel System Cleaner

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. 🚗⛽✨

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

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.

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!

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.

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.

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 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.
