Hot Shot's SecretGasoline Extreme 16 Ounce Bottle

Works great performs as advertised

Great to improve my mileage. I added 3mpg tp the car and it drives smoother. Make sure you know the size of your tank and calculate the proper amount to add to the gas tank. Don't dump the whole bottle without checking.

I don't normally write reviews unless I am impressed with something as I "expect" items to work as described. I have Ford Mustang that doesn't have a lot of miles on it but is 6 years old. I had a "rough idle" when you would start it up after sitting for awhile, but after about 30 seconds it was gone. It was worse when the weather was cold and moist and I left it parked in the driveway all weekend. I bought a bottle figuring it couldn't hurt. As directed, as used half of a bottle in my tank. I drove it down to almost a 1/4 of a tank (just over two weeks) and it still had a rough idle so I put the rest of the bottle in and filled it up again. I didn't notice it right away as the weather got hot, but the rough idle had stopped! It started up perfectly every time - even after sitting all weekend. I canceled the appointment with the dealership to look at it. I'm sure this saved me a lot of time and some money! I also noticed a gas mileage improvement shortly after I put it in my tank. I didn't buy it for that, but it is a nice feature!

Used this in my 2019 LR Discovery HSE (gas engine w/about 32k miles) Filled with 91 octane. Definitely felt better pickup after half tank. Gas mileage was slightly better but can’t tell if it’s cause of this or the Hotshot oil additive I recently added to my oil after oil change or a combo of both!Just added some to my son’s 2019 Tacoma too!

So my fuel guage was off a little. Fill up truck and gauge said 7/8 if a tank.. after just 1 bottle guage started working correctly. Now was a 20 yr old truck so sending unit had some tarnish on contact points. Better gas mileage after use.

We will soon find out if it works

Have Used A Lot Of Hot Shot Products For Years , With Good Results

Great product

Great product. Better fuel mileage and performance. Gonna order again.

Improved my mileage from a typical 13.0 L/100km to 11.2 L/100km (hwy driving on a regularly maintained truck) . I liked it so much I ordered 3 more bottles for other vehicles and future use.

Wasted money, didn’t work for my car, no change in gas mileage
