Mack’s Bulldog mDrive Transmission Fluid SAE 75W-80 for the company’s mDrive automated manual transmission is a fully synthetic heavy-duty transmission lubricant formulated to provide lubrication, component protection and fuel economy.
The fluid’s high viscocity index helps reduce viscous churn while providing smoother gear meshing and easier pumping and filtering, strong lubricating films at higher temperatures and added low-temperature fluidity for quicker starts, easier shifts and reduced wear during cold startups.
The fluid is formulated for added shear stability to enhance viscosity and film strength for better wear protection during severe operation, and its thermal durability and oxidation resistance help protect against deposit formation while contributing to long seal life, extended service intervals and up to 500,000-mile oil drain intervals.
It is available in both five-gallon pails and four one-gallon jugs. For more information, go to www.macktrucks.com.
