‎Hot Shot's Secret Gasoline Extreme 12 Oz, Concentrated Fuel System Cleaner, Fuel Additive for Gasoline Engines, Fuel Injector Cleaner - Increases Fuel Economy & Restores Engine Performance

Stuffs pretty good. I used two of these over the passed few months in my 2008 Expedition. With 180k miles I could clearly hear the injectors. After using this in the tank for the past two oil changes it's absolutely silent. Avg mpgs have gone from 14.7 to 15.8-16.0mpg (city) in my last 2 tanks of gas. I'll jeep using one every few months. But I'd recommend this if you're experiencing the same issues.

It really clean the system truck roon smother

For years, I used 44k once a year in my '15 edge sport to clean up the fuel system. I always had noticeable results using it, but this stuff seems to be even better. Within 1/4 tank, there was a larger increase in power than I'd ever seen with the 44k. Fuel economy is back to when I bought it with 45k miles, and I just passed 135k this week. Engine idles smoother cold now, though at temp it's always run beautifully, so that hasn't changed. I wasn't expecting results that matched 44k at a lower price, but... this exceeded it. I still believe 44k is a great product, but, now this is my go-to.

Can tell the difference since using this will continue buying for sure

Hard to tell if it works but didn't have any issues. 'Seems' to do its job. Maybe more of a placebo.

Great product. I use this a couple times or so a year to keep everything clean and running smoothly.This is my 4th or 5th time purchasing this stuff and I love it! Used to be a lot cheaper but it is what it is lol.

Have used this product in many different vehicles...5 stars! Everyone should use this every 5k - 10k miles! Does exactly everything the manufacturer claims...

This does what it says
