Save at the pump. Every time you fill up.

Savings vary by engine, fuel, and driving habits — see how to measure your own below.
One tablet. Molecular-level results.
Blaze tablets dissolve completely in your fuel tank and work at a molecular level — no additives, no residue.
Dissolves Completely
The tablet dissolves fully in the fuel and binds with the hydrocarbons on a molecular level.
Lowers Ignition Temperature
The active ingredients reduce the fuel's ignition temperature, improving the combustion process.
More Power, Cleaner Burn
Better combustion means more power with each piston stroke — and a cleaner-running engine over time.
Works in any engine that burns fuel
Cars, boats, lawn mowers, generators — one tablet treats 20 gallons. Small tank? Just break it in half.

Common questions about Blaze
How often should I use Blaze tablets?
For best results, use Blaze every time you fill your tank. Consistent use helps clean and maintain optimal performance of the combustion chamber.
Is Blaze environmentally friendly?
Yes. Blaze helps reduce carbon and other harmful emissions. Any fuel you save also eliminates the CO2 and emissions that would have come with burning it.
What type of fuel can Blaze be used in?
Blaze works in all hydrocarbon fuel blends — gasoline, diesel, ethanol, and methanol. For methanol specifically, apply the tablet several hours before use to ensure it fully dissolves.
What's actually in the tablet?
Carbon, hydrogen, and a molecular combustion catalyst.
Will it work with my lawn mower, boat, or small engine?
Yes — Blaze works in any combustion engine, large or small. One tablet treats 20 gallons; break it in half for smaller tanks, or use more than one for larger ones.
