## Description

Techron High Mileage Fuel System Cleaner is specially formulated to clean and protect classic cars and all vehicles over 75,000 miles.

One 12oz bottle holds up to 21 gallons of gasoline. Recommended Use: Gasoline, ethanol, gasoline/ethanol ignition engine hybrid vehicles Will not damage catalytic converters or oxygen sensors. Not recommended for diesel engines Not for aviation use

Review: 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.
Review: Great product for my vehicles, use it offer to keep it run clean. Buy it several times a year, works very well.

## Questions & Answers

**Q: Is there any reason why after using this that I should also use Chevron's fuel injector cleaner or does this do the same thing?**
A: The fuel injector cleaner is for use every 1,000 miles after the initial use of the complete system cleaner when doing an oil change. My Kia recommends using Chevron system cleaner at every oil change, and I'm also going to put the fuel injector cleaner every 1,000 miles after the oil change. You don't put, both in at the same time.

**Q: I found an old unopened bottle of the original concentrate, not the Plus. Probably 10 years old. Is it still OK to use.**
A: Yes, its fine to use.  The ingredients don't go bad for maybe 20 plus years or more

**Q: it's a real pain to open Techron bottle's seal.  do you guys have any tips on opening it easily?**
A: I punch the seal with the end of a closed pocket knife. Makes a large enough opening.  You don’t need to peel off the foil seal.

**Q: How is this different than the older techron "fuel system cleaner," that also is supposed to clean injectors?**
A: pro guard is not as concentrated as the full strenth black bottle that i have used for years at my repair, with the new fuel injection systems that have come out the last few years,They have carbon built up problems on the valves.I would only use the full strench in my cars every oil services

*by R***E on February 18, 2026*

With these fuel additives, you can never be quite sure if they offer any benefit at all-especially if your car is running fine before you use them. I look at it more as preventative maintenence, as it seems to make sense to use a bottle in the gas tank every few thousand miles. And I feel better when I do. Peace of mind is priceless.
