High Viscosity Synthetic Blend 80W 90 for API GL-5, MT-1 service Mack GO-J, SAE J2360. Synthetic materials are the greatest option for long-term performance. To find out how to fill and flush your engine, consult the manufacturer's engine service manual. If none are offered: 1) Disconnect the upper and lower plugs on the bottom unit gear case and drain the old oil entirely. 2) Place the fill tube in the lower hole. For simple installation, we suggest utilizing the STAR BRITE Lower Unit Quart Pump (#27400), Lube Tube (#28600), and Adaptor (#28401, #28402). 3) Slowly re-lubricate the device until fluid reaches the upper hole's lip. 4) Reinstall the upper plug and firmly tighten. 5) Remove the bottom stopper and fill tubing from the lower hole. Retighten firmly.
