Hot Shot’s Secret Gasoline Extreme 32 oz – Treats 50 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

Goes in every gas engine I own Amazing product

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.

Why did you pick this product vs others?: Saw this product on a car engine show. According to the pitch, it supposedly increases gas mileage by cleaning the injectors. My observation after using it in a 48 gallon tank, & driving 500 miles on interstate: vehicle computer showed that MPG increased about 1.1 MPG; gas gauge appeared to drop slower than normal; trip computer indicated that "Miles To Empty" also dropped slower. With my next tank refill, MPG started declining. Now .6-.7 MPG less than when product was in the tank. I can only conclude that whatever is in this product coats the sensors, thereby making the vehicle computer think that it's consuming less fuel. Would I use again? Undetermined. Update 7-29-25: Completed another 980+ mile trip. Vehicle calculated MPG at 75-80 MPH (interstate) was 13.4!! I'm buying more before the price increases, or some government agency makes the company change the formula.

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

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.

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
