How to Test Ferox Yourself

The best way to understand Ferox is to test it in a vehicle you already know well.

1

Choose a Familiar Vehicle

Start with a car, truck, or piece of equipment you drive regularly. Make sure you know your previous MPG, distance to empty, and throttle response feel.

2

Drop In the Correct Tab

Add the recommended Ferox tab to your tank before fueling. It's okay to use multiple tabs to make sure all your fuel is treated. Ferox can also be broken for different measurements of treatment.

3

Fill Up and Drive Normally

Use the vehicle the same way you normally would. There is no complicated process.

4

Pay Attention Through the Tank

Notice throttle response, engine smoothness, cold starts, MPG, distance to empty readings and how the vehicle feels during everyday driving.

FAQ

Know Before You Drop A Tab

Ferox is a compact, solid fuel treatment tab designed to elevate the way your engine runs, fuel burns, and emissions clean. It’s not a liquid, not a gimmick, and not an additive—it’s a catalyst, and simply a smarter way to fuel every tank.

Yes — Ferox is fully compatible with diesel. What's great is the same pack you use in your gas lawn mower works in your big rig or F350. Why? Because Ferox doesn't shift fuel properties, it only improves combustion which means it can go in any fuel.

Our Green Pack is formulated for larger fuel capacities and offers optimized combustion for diesel engines, helping them run cleaner, stronger, and more efficiently.

The only difference between each pack is how much fuel each tab treats. Any of our tabs can be used in any type of fuel.

Ferox Blue - treats 20 gallons per tab, with 10 tabs in each pack

Ferox Red - treats 8 gallons per tab, with 10 tabs in each pack

Ferox Green - treats 50 gallons per tab, with 6 tabs in each pack

Ferox Sample Packs - treat 20 gallos per tab with only 4 tabs in each pack

Just drop 1 tablet into your tank before you fill up.

It dissolves instantly and treats the entire tank as you pump.

Use it every fill for the best performance and engine cleanliness.
