ChevronTechron High Mileage Fuel System Cleaner, 12 oz, Pack of 1

One of the best products out there. Backed by science. 2nd largest concentration PEA product (PEA is basically the best cleaning agent for this sort of thing). Noticeable difference after using.

This is a good additive for you car. I bought it because I always keep a supply of it. I do not use it every time I fill my tank. It is better use it after your car is close to being empty. Put it in first before filling the gas tank. With the long neck it makes it easy to put in your tank without spillage. Since my car is a 1999, it has helped me keep my car running good. It does not run hard at all. Buying it from this site is a great value compared to getting it at the auto parts store.

Delivered on time and undamaged. Product works well.

It really helps with the gas mileage. I put it in when I'm getting ready to fill upMy tank

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 useHelps maintain fuel system cleanliness, especially important for high-mileage enginesEasy to pour, good packaging, and widely availableCons:I didn’t see a dramatic increase in MPG, just a slight improvementIt’s not cheap if you're using it regularly, but I consider it preventative maintenanceOverall, 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.

This is a top product for cleaning fuel injectors. I noticed a significant improvement in my engines performance.

I was skeptical at first but it cleared up the rough idle in my truck

A good product, and hopefully fulfills its intended purpose.
