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

Works well in small equipment, pressure washers, lawn mowers, etc. to keep that fuel system clean and working. A small cost to avoid bigger problems, especially with the quality in today's gas.

Have been using this on my cars since they were both new (I started with the regular and then moved to the high mileage one). My cars now have 180k and 160k miles on them respectively and are going strong. I take very good care of my cars and this is part of my regimen. I would recommend it!

ive used this in all my cars. The low RPM throttle response improves so much. engine runs smoother too

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.

The fuel gauge on our 2006 Toyota 4Runner was not working properly. After refueling, the gauge would sometimes read full, sometimes half full. It was very erratic. After using the Chevron fuel system cleaner on two fill ups, the gauge started working correctly again. It's been over a month and the fuel gauge is still working correctly. I've ordered a couple more bottles for future use, if necessary.

This is a "blind" 4 star lol. I don't know what it does to the engine/car but this is my to-go brand for fuel injector and so far no issues with the car. I can't say it's because of this or the car has perform great...maybe a placebo affect? But at 130k on the car, adding this to a regular oil change doesn't seem to hurt...?

I'm a long-time user of fuel treatments. The good ones really do work to maintain good fuel mileage and a good idle. I'm aware of what are reputed to be and seem to be the two (maybe three) BEST brands. Chevron Techron is one of those brands. This is my first purchase of the High Milage version, but one assumes it is just a more concentrated offering of the usual product.

Rate for high mileage vehicles should do it every Oil Change. Keep those injectors clean.
