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

Over 140k miles and use once a year for the past 5 years. Car runs and idles almost new. Great product

Recommended by nearly every reviewer and I find my car running smoothly, less sluggish at stop and go. The additive may have solved a gasoline quality issue. I intend to use it every year.

The active ingredient will survive combustion and clean your Catalytic Converter.

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.

used in F150 eco junk. 3.5. cleaned out carbon. runs best it ever has. 98.000 miles. also. 05 Buick 3.8. runs great. ill use. every oil change. alot of wrenchers swear by it. it works.

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.

Great stuff if you own a C5 Corvette. Helps with the fuel gage sticking issue.

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!
