Combustion catalyst — not just a detergent additive
Compatible with ULSD, biodiesel B5-B20, and all diesel engines
Anti-Gel Protection Down to -40°F
Fuel Ox Cold Charge prevents fuel gelling, improves cold starts, and stops ice crystal formation in fuel lines. Northeast, Midwest, and mountain fleets trust it from October through April. Zero gelling incidents reported in fleet trials.
We switched our 120-truck fleet to Fuel Ox last winter. Fuel economy improved 6% across the board, zero gelling incidents in sub-zero temps, and DPF regen frequency dropped noticeably. The ROI paid for the additive in the first month.
