FAQS

Everything you need to know about Green Fuel Tabs, Green Fuel Oil, and fuel treatment for diesel engines is answered simply and clearly.

What is a diesel fuel additive?

A diesel fuel additive is a product added directly to your fuel tank to improve how your engine burns fuel. Unlike basic fuel injector cleaner products that use detergents, Green Fuel Tabs work as combustion catalysts. They change how fuel burns at the molecular level, allowing more complete combustion, better mileage, and far fewer harmful emissions with every cycle.

What is the best diesel fuel additive for trucks?

Truck Fuel Tabs are purpose-built as a diesel additive for trucks, RVs, and heavy-duty diesel engines. Each tablet treats 50 gallons, and the 6-tab fleet pack covers 300 gallons (1,140L). For commercial operations that need bulk coverage, Green Fuel Oil is available as a 1-gallon concentrate treating 5,000 gallons or a 55-gallon drum for large-scale fleet and trucking operations.

Can Green Fuel Tabs help reduce vehicle emissions?

Yes. Green Fuel Tabs are specifically designed to reduce vehicle emissions, including CO₂, carbon monoxide, sulfur oxides, nitrogen oxides, unburned hydrocarbons, and fine particulate matter (PM₁₀). Because more fuel burns completely on every combustion cycle, far fewer harmful gases leave the exhaust. Independent testing shows emissions reductions of 40 to 80 percent, making Green Fuel Tabs one of the most effective ways to lower your vehicle's environmental impact without any engine modification.

How long does it take to see results from fuel treatment for diesel engines?

Improved throttle response and smoother performance are typically noticeable within the first few tanks. Full benefits, including maximum mileage improvement and complete removal of pre-existing carbon deposits, are generally realized after approximately 4,000 miles or 600 hours of engine operation. The exact timeline depends on engine age and the extent of existing carbon buildup.

Are Fuel Saver Global products safe for my engine?

Yes. All Fuel Saver Global diesel fuel additives are EPA registered and built on proven combustion chemistry. They do not modify engine management systems, do not boost octane artificially, and are fully compatible with both diesel and gasoline engines. They do not void standard manufacturer warranties when used as directed.

Which product should I choose: Green Fuel Tabs, Truck Fuel Tabs, or Green Fuel Oil?

Choose Green Fuel Tabs for everyday cars, pickup trucks, and light-duty vehicles. Choose Truck Fuel Tabs if you operate heavy-duty diesel trucks, RVs, or fleet vehicles that run on large fuel tanks. Choose Green Fuel Oil if you manage a commercial fleet, agricultural operation, or industrial equipment requiring high-volume bulk fuel treatment for diesel engines. Not sure?
