Mobilgard HSD Marine Diesel Engine Oil 20W-50 is an extra high performance, multigrade diesel engine oil from ExxonMobil, formulated for severe service high-speed diesel engines in marine applications. Its advanced chemistry controls oil thickening from soot build-up and high temperatures, resists oxidation, corrosion, and high temperature varnish deposits, and holds a stable oil film at all operating temperatures for reduced oil consumption and strong wear protection, with the extra film strength of a heavier 20W-50 grade for hot engine rooms and worn engines. With a 9 TBN reserve it protects engines running on low or high sulphur distillate fuel. It meets API CI-4 and is recommended for applications requiring API CF, CF-4, and CG-4, Cummins CES 20071 and 20072, and MAN M 3275-1, covering modern low-emission and older high-speed diesels such as Caterpillar 3500 Series and smaller bore, Cummins, Volvo, Daihatsu, and Yanmar engines. Supplied in a 5-gallon pail that is easy to carry aboard for top-offs and compact engine rooms. A proven choice for tugboats, fishing fleets, crew and supply boats, and dockside generator sets across South Florida and the Caribbean. American Oil Wholesale stocks Mobilgard at our Hialeah warehouse minutes from PortMiami and the Miami River, with wholesale and bulk pricing, next-day delivery across Miami-Dade, Broward, and Palm Beach, and EXW Miami for export and marine suppliers.
