Features and Benefits

Mobilgard HSD+ 15W-40 engine oil is formulated with optimised base oil technology, containing severely hydro-processed base stocks and a tailored additive system to deliver extended performance – up to 50 per cent beyond OEM-recommended oil drain intervals (ODIs).* This proprietary formulation delivers excellent wear protection, great oxidation stability, outstanding TBN retention, and excellent resistance to oil consumption, oxidation, corrosive and abrasive wear, and high-temperature deposits.

Advantages and Potential Benefits
Outstanding oxidation stability Extended ODI capability*; reduced low-temperature sludge buildup and high-temperature deposits
Excellent soot and viscosity control Greater engine efficiency, long engine life and long oil life
Component compatibility Long gasket and seal life
Low ash formulation meeting API CK-4 requirements Protects life of exhaust after-treatment systems (DPF, DOC and SCR)

*Results may vary based on vessel/engine condition, load and environmental conditions. Consult OEM or ExxonMobil before implementing extended ODIs.
