MILES ALL SPEC 15W40 is formulated to meet or exceed the warranty requirements of all manufacturers of diesel and gasoline engines. This oil is formulated to meet the Mack EO-O Premium Plus '07 specification and API CK-4/SN specification for use in EGR equipped heavy-duty diesel engines in high output service. Advantage 15W40 Premium Plus meets the performance requirements of most diesel engine manufacturers such as Caterpillar, Cummins, Detroit Diesel, Ford, Mack, Navistar, and Volvo. It can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel engines, turbo-charged or non-turbo-charged and well as gasoline engines. Since the introduction of ultra-low sulfur fuels, high TBN oil is no longer a crucial need. Field tests have shown our CK-4 oils retain TBN levels for longer periods due to the advanced technology of the new additive chemistry. This oil meets or exceeds all the requirements of API CJ-4,CI-4, CI-4 Plus, CH-4, CG-4, CF-4 and SN. ADVANTAGE 15W-40 also meets the extended drain requirements of Cummins CES 20076, Mack EO-O Premium Plus, and Volvo VDS.
