One small tablet dropped in your tank before you fill up helps your engine burn more of every gallon completely — better mileage, cleaner injectors, and lower emissions, in the car or truck you already drive.

Every engine leaves some fuel only partially burned. That unburned fuel doesn't disappear — it turns into carbon deposits in your injectors and cylinders, and gets pushed out as extra exhaust. Here's what that's quietly costing you.
Many drivers pay 50–60 cents more per gallon for premium, chasing performance a cleaner-burning engine can deliver on regular.
Deposits in injectors and combustion chambers reduce efficiency and push maintenance intervals closer together.
Higher hydrocarbon and CO output from incomplete combustion makes it easier to fail an emissions check.
Lower mileage means more trips to the pump — small losses per tank add up fast over a year of daily driving.
No engine modifications. No new hardware. Just a catalyst that goes to work the moment it hits your tank.
Add one tab sized to your tank right before you fill up. That's the entire process — no tools, no mechanic.
An organo-metallic combustion catalyst attaches to fuel molecules and lowers the temperature needed for them to fully ignite.
With more of every gallon actually combusting, you get more miles from the same tank and cleaner exhaust out the pipe.
Gas and diesel molecules need to reach a fairly high temperature before they'll fully ignite — and combustion chamber heat is never perfectly even. The pockets that don't get hot enough leave fuel half-burned, which is where carbon deposits and extra emissions come from.
Green Fuel Tabs lower that ignition threshold, made from organic, natural ingredients with no detergents, and formulated with a patented quick-dissolving design so tab particles don't clog your fuel system. The result: more of every gallon converts to usable power, and existing deposits gradually clear out the longer you use it.
The average customer sees 10% to 25% savings at the pump with each fill-up.
More complete combustion means less unburned fuel leaving the tailpipe as toxic exhaust.
Made from organic, natural ingredients — nothing harsh going through your fuel system.
Used by thousands of drivers in cars, trucks, and fleets for over two decades.
Doesn't alter your fuel's properties, so it won't affect your manufacturer's warranty.
Registered with the EPA (#23772000) and backed by a money-back guarantee.
Whether you're driving a compact sedan or a full-size pickup, there's a tab pack sized to fit.
Each tab treats 10 gallons — a perfect fit for a compact or midsize car's tank, and a low-cost way to try it for the first time.
Each tab treats 20 gallons — matched to bigger tanks on full-size trucks and SUVs, gas or diesel.
A high-mileage SUV owner's mpg climbed from 20.4 to 24 — about two extra gallons of range per fill-up, with noticeably stronger throttle response and a cleaner-smelling exhaust.
After switching to a single tab with regular fuel instead of premium, one driver reported the car running better than ever while picking up about 70 more miles per tank.
A twin-turbo pickup owner measured a 21% mileage improvement, stretching a tank that used to run about 660 miles to over 815 miles.
Yes — it's safe for all gas and diesel engines, made from organic, natural ingredients with no detergents, and uses a quick-dissolving formula so no particles reach your fuel system.
No. It doesn't alter the properties of your gas or diesel, so it doesn't void a manufacturer's warranty, and fuel-related warranty protections are covered under federal law regardless.
Many drivers who previously used premium for performance find they no longer need it, since the tab helps regular fuel burn more completely — worth testing over a few tanks to see what your engine prefers.
Track your mileage over a baseline of a few tanks before starting, then compare after using tabs for 3–10 tanks. If you want hard data, an emissions retest against a baseline test is the clearest before-and-after proof.
There's a money-back guarantee — if a tank of fuel doesn't save you at least the cost of the tab, the difference is refunded, up to the price of the product.
Green Fuel Tabs are EPA-registered, backed by 25 years of use and a money-back guarantee, and work with the car or truck you're already driving — no shop visit required.
