Product review: Hot Shot Gasoline Extreme

Hot Shot’s Secret Gasoline Extreme has impressed me. It has rejuvenated my car from something I already liked into WOW! A performer I really enjoyed!


Like yours, my car has sat quite a bit over the past few months. Being shut in has not been much fun for anyone. While Arizona seems to be getting back to normal, I’m still not doing my daily commute to the ClassicCars.com offices and making the occasional trip to the grocery.

However, a couple weekends a month, I shoot over to Orange County, California, from Phoenix to spend time with my three daughters. It has become a routine drive, 378 miles each way. That equates to a 10-hour round trip – of course, I have a record and really, my average for the trek each way is a hair over 4.5 hours. My car, a Mercedes CLK350 Convertible has made the trip dutifully.

injector cleaner

A few months ago, I was chatting with one of the PR people at Hot Shot’s Secret and she told me about this injector cleaner. As always, I am pretty skeptical of “mechanic in a bottle” products but agreed to drop eight ounces (which is recommended to treat 10 gallons of fuel) of the snake oil in my gas tank for the round trip.

The collateral information says, “Gasoline Extreme is a powerful injector cleaner.” Needless to say, we put a lot of different types and brands of gas in our cars. In my case, I have downgraded to mid-level-fuels rather than the usual premium as I just refuse to pay $3 or more per gallon. The result is deposits that gum up injectors and valve guides. My car does not run badly, has plenty of pep, but I was in for a surprise.

Hot Shot’s Secret claims, “The fully-formulated, concentrated cleaner removes combustion chamber and intake valve deposits while cleaning injectors, valves, pumps, rings and pistons. Gasoline Extreme lubricates key components in the fuel system, including upper cylinders, while restoring fuel economy, power and performance.”

A long drive in the car, such as the one I take to California, usually does a good job of blowing out the carbonite, but this stuff was amazing. I put about 10 ounces of the fluid in my tank prior to a fill-up before leaving. The car ran well on the way, but the surprise was on the way back. It felt like getting a fuel-system flush. There was seemingly more power and more throttle response as I made the trip back to Arizona; the car just felt more slippery. Interstate passes were almost effortless.

I will continue to use this treatment. It really made a genuine difference. Sometimes mechanic in a bottle snake oil works. …and by the way: I set a new record.

  1. All subjective, no quantitative results. Nothing to refute the claim that this is just bilking the car owner of hard-earned money. “Slipper?” “Seemingly?” Come on! This is insulting to everyone’s intelligence.

  2. Ridiculous and anecdotal. You present as an ‘expert’ and offer no value to the average consumer trying to make wise purchases to maintain their car. Makes me think you’re a hired Gun.
