Mobilgard™ 300 C system oil
Mobilgard™ 300 C is a next-generation system oil specially engineered to help improve cleanliness in two-stroke crosshead diesel engines. Its balanced formulation combats deposits and sludge buildup, especially in the most susceptible engine components – such as the piston undercrown and crankcase.
Mobilgard 300 C system oil may help:
- Result in cleaner engine components, helping bearing and gear life
- Provide balanced anti-wear protection, even under high loads and at extreme temperatures
- Protect against rust by enabling water separation
- Extend maintenance intervals and lower operational costs
