Fuel treatments come with a lot of noise. That's why we let real drivers speak for the difference they feel.

Drew Pirtle

"I've noticed a huge change in my vehicle since I started using these. I bought them over a couple of months, and my car definitely runs better. They are super easy to just drop in your tank. I keep them right in my glove box and just take one out when I go to fill up and drop it in before I fill up. There's no residue left on your fingers, so you don't have to worry about anything rubbing off. They are in a convenient, small zip-up package. The packaging is very high quality, the same with the little pills; they don't crumble when you try to pick them up out of the bag, there's no smell, and like I said, they fit right in your glove box or center console, and the bag re-closes, so if you have kids, you don't have to worry about them accidentally opening the bag and then spilling all over."

Madison King

"I was honestly a bit skeptical at first, but Ferox fuel tablets actually made a noticeable difference for me. Before using them, my average gas mileage was around 27 mpg, and after a consistent use, I’m now averaging closer to 29 mpg. It’s not a dramatic jump, but over time it definitely adds up and saves money at the pump. The tablets are easy to use and I didn’t notice any negative effects on how my car runs. The engine feels just as smooth as before, and I like knowing I’m getting a bit more efficiency out of each tank. If you’re looking for a simple way to slightly improve fuel economy, these are worth trying."

"A friend mentioned this product to me and I was excited to find it on Amazon. My vehicle is 18 yrs old and was having trouble starting. I commute hundreds of miles weekly through inclement driving conditions. I'm so glad I tried FEROX! After only a couple tank fill ups I noticed a big difference. My car runs smoother, it's quieter, starts easily, and I'm not filling up as often as before. It's so easy. There's nothing difficult to understand, nothing to set up, just a tablet that you add when you fill up. And it even has separation marks for easy splitting in case you're only filling up 1/2 tank or so. No waste! I was also thrilled to find out it's Made in the USA. Whether you have an older or newer car, no matter where you live or how much or little you drive, USE this! It truly works. It's also a great gift idea for friends and family. Great product, I love it! Thank you FEROX!"

FAQ

Know Before You Drop A Tab

Ferox Red is designed for gasoline engines with fuel tanks 8 gallons or less, including powersports and small equipment. Even in mixed gas for 2 stroke engines.

Yes. Ferox Red is safe for modern small engines and fuel systems when used as directed. Our tabs are scored so you can dose the correct amount every time.

Most users notice smoother more powerful throttle response, stronger pulls under load, and a more consistent engine feel—especially during hard use.

Ferox Red can be used one-time, but many riders and operators choose continuous use for the best experience and long term engine protection & performance.

Just drop 1 tablet into your tank before you fill up. Use it every fill for the best performance and engine cleanliness.

Ferox comes in a drop-in tab:

  • No measuring
  • No spills
  • No storing bottles

While most additives clean the fuel system or emissions after the fact, Ferox focuses on combustion itself—helping fuel burn more completely to reduce buildup and inefficiency.

Ferox Red is best for riders, racers, and operators who push small-tank gasoline engines hard and want smoother, more consistent performance.
