To keep the entire fuel system clean, use Techron High Mileage every 1, 000 miles or as needed for your high mileage vehicle. 1 One 12oz bottle treats up to 21 gallons of gasoline. Recommended for use in: Spark ignition engines with gasoline, ethanol and gasoline/ethanol blends Gasoline hybrid vehicles. Will not harm catalytic converters and oxygen sensors. Not recommended for diesel engines. Not for aviation. Review: Worked For Me, I’ll Use It Again - 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. Review: Best you can buy - 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. ## Features - Restore power and performance - Restores lost power and performance by removing gum, varnish, and other fuel system deposits. - Maximize fuel economy - Keeps engines clean, and protects from deposits that rob engine efficiency and reduce fuel economy. - Protect the fuel system and fuel gauge sensor from various types of corrosion - Multiple corrosion inhibitors protect metal components (both ferrous components like iron and steel, and non-ferrous components like copper and silver) from the damaging effects of corrosion. - Vehicles with higher mileage accumulation can suffer from the effects of age - including carbon build-up and corrosion in the fuel system.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked For Me, I’ll Use It Again *by M***G on July 7, 2026* Recommended by nearly every reviewer and I find my car running smoothly, less sluggish at stop and go.
