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. 🚗⛽✨

This fuel system cleaner does the job well. You can feel a little more smoother ride. Is easy to put in on your fuel tank. Seems that it holds durability. My 2008 Kia Sorento has almost 180,000 miles on it and still holding strong and with this on your tank gets a little extra power by cleaning the fuel system. Use it especially if you’re using a non-Top Tier gas station. But no matter if I used Top Tier gas like Shell, Chevron, Exxon or Costco you can’t go wrong to use once or twice a year. Recommend it.

Excellent product, functioning effectively as a fuel system detergent. Vehicles with saddle tanks often accumulate deposits on sending units, leading to erratic gauge readings. Multiple applications gradually restored precision to the indicator in my classic. This insight, shared within an enthusiast community, yielded comparable positive results for others.

The best injection clean in the market

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.

High mileage Honda with 230,000 miles was hesitating in the morning. Added one bottle to 12 gallon tank and the vehicle started running smoother immediately. I researched all brands and this had the best scientific data to support effectiveness. I am sold on this brand and will buy again.

I’ve been using this for years. My car always mor pick up compared to other brands and Amazon was the cheapest I’ve found. Great product!!!
