‎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

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.

excellent product quick shipping

This stuff works! I've noticed a difference in performance and emission tests are better with it than they were before using it.

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.

after only 100 miles I noticed a dramatic difference during engine idle, much smoother, 100 less rpm. Several times at traffic lights, I had to look at the tachometer to assure engine was still running, because it Was so smooth. I did not notice an increase in fuel mileage. I would recommend using a funnel to pour in the tank. the bottle threads are raised and coarse, much more prominent than other brands I have used. I got the bottle stuck behind the tank inlet flapper, and it took some careful prying for about 10 minutes with a long screwdriver to get it back out.

So far so good!👍🏻 I can definitely notice the over all improvements... smoother idle & performance. I use the oil additive too.

Made my 2004 f150 truck smooth like silk..and im still 1 quart away from an emoty tank..

I’ve always used their products in my diesel trucks. The additive from klotz I used in gas engines is no longer available. This additive seems to be nearly as good and much more available
