LX4 is a concentrated, solvent-free formula designed to replace lost lubricating properties, reduce metal-on-metal wear, and help maintain smooth fuel-system operation without harmful alcohols or solvents.\u003c\/p\u003e\n\n\u003ch3\u003eHow does LX4 protect fuel pumps and injectors?\u003c\/h3\u003e\n\u003cp\u003eLX4 increases fuel lubricity—measured improvement up to 56%—so moving parts within pumps and injectors receive a protective film that reduces friction and abrasive wear. Regular treatments help prevent premature component failure that can result from dry or low-lubricity fuels.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRestores lubricity lost in ultra-low sulfur fuels\u003c\/li\u003e\n  \u003cli\u003eForms a friction-reducing barrier on metal parts\u003c\/li\u003e\n  \u003cli\u003eCompatible with common fuel system materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill LX4 work with my gasoline, ethanol blend, or diesel?\u003c\/h3\u003e\n\u003cp\u003eYes. LX4 is formulated to be versatile across fuel types, including gasoline, ethanol blends and diesel, so one product can be used for mixed fleets or small engine equipment.
