Excellent product, functioning effectively as a fuel system detergent. Vehicles with saddle tanks often accumulate deposits on sending units, leading to erratic gauge readings. Multiple applications gradually restored precision to the indicator in my classic. This insight, shared within an enthusiast community, yielded comparable positive results for others.

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.

A fuel system cleaner that works. Made my Kia Sorento run smoother.

I filled up with chevron 89 gas, poured in the high mileage treatment and my check engine light finally went out after the second tank of Chevron 89. It saved me a $2000 converter replacement. Like the Japanese say, “Cheap gas is too expensive”.
