Techron High Mileage Fuel System Cleaner 12oz

As good as any, better than most.

Seemed to improve function in old honda

To improve engine efficiency

Best fuel additive in my opinion. Dont expect extreme numbers like +10 mpg's or 30+ horespower, realistically added 3 mpgs to my daily drive and my tank lasted 4 days longer than usual.

Great product! Actually makes a difference.

Seems to be a good gasoline system detergent.

This product keeps my vehicles running at there best performance and gets there best gas mileage! I having using the gas treatment in all my vehicles since 2008!

Keeps your Intake system clean

My Subaru has no fuel filter. It had a hesitation in the throttle. 2 bottles cured that 100%

Have been using this product for years.. Keeps injectors clean..

I used the product for my 2007 Ford suv

Techron is the best out there. Makes a big difference in my wifes high mileage car. her car runs and sounds great. I also use it in my lawn mower, just a little and it helps. My lawn mower is 14 years old and it makes a big difference. Only brand i buy.

Car responded to additive

Excellent product. I've used it for over 10 yrs on all my vehicles. Improves fuel economy and does a great job restoring lost power.

This stuff works

I drive a 2023 truck. Always used Licas but tried this because it was BOGO. Used it then my engine had a hard time starting, never happened before. It almost stalled a few times, which it's never happened before either. Went back to using Lucas brand and engine runs good again.

I use the regular complete system cleaner and fuel injector cleaner with great results. I’m using the High Mileage fuel system cleaner for the first time because I’m storing my car and it says it helps stabilize the fuel for 24 months. Time will tell if this products works.

Techron wins every competition of fuel additives.

I can definitely tell the difference after using. I used two small bottles at the same time in my Impala

Does the job!
