Hot Shot's Secret Gasoline Extreme 1 Quart Bottle

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’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

Goes in every gas engine I own Amazing product

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.

Couldn’t tell any difference at all, and this stuff is too expensive for it to not work. Fortunately found one that solved the problem a lot cheaper. Hots Secret makes great diesel fuel products but the gas treatment is a waste.
