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

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!

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...?

Great product for cleaning injectors on a Ecoboast direct injection engine.

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.

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

Gas MPG was around 20 I'm getting solid 23-25 in city now
