10 oz Bottle of Lubegard Standard Fluid Protectant Additive LUBEGARD® Gear Fluid Supplement is designed for use in all manual transmissions, manual transaxles and final drives that require gear oil. LUBEGARD® contains LXE (liquid wax esters) and their derivatives, a blend of high grade petroleum oil and synthetic base oils and a complete anti-wear formula.

Lowers temperature and extends fluid life; improves heat transfer from fluid to the case wall and out the gear box; improves gas mileage by reducing drivetrain power loss, improves all cold weather stiffness, improves all synchromesh transmission shift characteristics; reduces tooth drag and absorbs shock loads, thus improving the life of all gear units; lowers friction on bearings and gears with high wiping stresses, especially hypoid gears; minimizes oxidation and varnish deposits; suppresses lubricant foaming; safe for new MTF fluids.
