Hot Shot’s Secret Gasoline Extreme 12 oz – Treats 20 Gallons – Concentrated Fuel Additive for Gasoline Engines, Fuel System and Injector Cleaner, Restores Engine Performance

PEA is a great detergent to keep fuel system clean and hopefully reduce carbon build-up. Top tier gasoline has great detergents in their gasoline. However, if you are not using a top tier gasoline this should help. According to instructions use every 10,000 miles. Other PEA users suggest every oil change. I am going to use it at every oil change. Word of caution: the package arrive and the one container was leaking. I hope someone from Amazon reads this and does a better job packaging the product. Tape around lid or individual plastic bag for each bottle.

Let me ask you a question do you want fuel treatment clean out your fuel system this is what you need not going to say it's going to help fuel mileage for sure but definitely a great for helping your engine out

You know, I have never personally ripped apart any of the engines in my vehicles, so I cannot say that my engines and injectors are actually cleaner because I use Gasoline Extreme. But, I can say that I do keep my vehicles a long time, do the required regular maintenance and add 20ozs of Gasoline Extreme to each gas tank at every 5000 mile oil change. As a result, all of my vehicles run well and remain dependable. In the absence of always being able to get top tier fuel, I believe it does help w/cleaning and lubricity. After doing some research, I also think there is credible reason to believe that the added detergents and cleaning additives are beneficial to engines.

Goes in every gas engine I own Amazing product

Helps I think Not sure

great cleaner has all of the right stuff in it

It seems to be running better, but I’ll wait till I went through whole take

I am thoroughly impressed with this product, it actually delivers on the hype. I used this in my 2016 Altima that was averaging between 37 to 39 mpg depending how much in- town driving I did and after using the Hot Shots, I was getting 42 mpg my last fill up. I will basically pay for itself after a few tanks.

Great product, good container design. I use it twice a year, with winter tire changes as a reminder, and supplant with Hot Shot's Every Day Diesel or Winter Defense at fuel-ups.

I’ve been using Hotshot Secrets lineup of additives in many vehicles over the years; and this gasoline extreme works well! From small engines, to everyday drivers if your gas powered car is running rough, try this first. I’ve seen slight MPG gains from this, smoother running engines, & easier to start situations. Would purchase this again
