Fuel FAQs

MPG X-Caps are a concentrated fuel additive family. Marketplace Global describes X-Caps as a multi-functional fuel additive compressed into fast-dissolving caplets or related product formats for gasoline and diesel engines.

The fuel product family includes standard X-Caps for many personal vehicles, Mini Motos for small tanks and small engines, and Xtreme Crumbs for larger tanks, commercial vehicles, fleets, heavy-duty equipment, or bulk-treatment situations.

Marketplace Global describes X-Caps as a concentrated powdered or granulated fuel detergent and combustion additive format, rather than a highly diluted bottle with a large amount of carrier fluid.

Marketplace Global states that a standard one gram X-Cap generally dissolves in about 25 to 40 minutes, depending on the aromatic quality of the gasoline or diesel fuel.

Marketplace Global presents X-Caps for gasoline, ethanol-blended gasoline, diesel, and biodiesel applications. Visitors should still use the correct format and amount for the actual tank and application.

Marketplace Global’s FAQ language emphasizes using the recommended size of X-Caps with each fill-up for maximum benefit, because the product treats the fuel in that tank.

Marketplace Global lists octane support as one of the product benefits. Any result depends on the fuel, vehicle, engine condition, and how the product is used.

Yes. Mini Motos are positioned for smaller tanks and small engines such as motorcycles, scooters, ATVs, lawn equipment, generators, snow blowers, jet skis, and similar applications.

Results vary. Fuel economy, smoke, emissions, power, octane, and engine cleanliness can be affected by vehicle condition, maintenance, driving habits, fuel quality, load, weather, and many other factors.

Choose based on tank size and use case. Standard X-Caps are commonly positioned for many personal vehicles, Mini Motos for smaller tanks, and Xtreme Crumbs for larger or commercial tanks. A representative can help compare options.
