Kubota Heavy Duty Engine Oils are engineered to meet the most demanding lubrication requirements of todayﾒs naturally aspirated, turbocharged, and supercharged diesel fueled engines, including engines with cooled exhaust gas re-circulation (EGR). They are formulated with advanced additive technology (including foam control and soot dispersancy additives) and premium quality basestocks to protect engines against undesirable deposits, corrosion, oxidation, wear, and viscosity and thermal breakdown under severe service conditions. They meet the highest API (American Petroleum Institute) Service Categories for modern low emission diesel engines. These oils can also be used in transmission, hydraulic systems, and other industrial applications where the manufacturer recommends the use of an engine oil.
