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

Best gas treatment on the market! Improves gas mileage and makes your auto run much better.

great cleaner has all of the right stuff in it

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.

I needed a fuel system cleaner for my 2020 Nissan that I have never done a cleaning on. Came accorss this product and the reviews were amazing. So we gave it a try! Its cleaning power is top notch. Gave me my power back when accelerating! Very effective!

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.

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
