Marine Diesel Engine Cylinder Oil

Marine Diesel Engine Cylinder Oil

Mobilgard™ 5100 by ExxonMobil is a premium quality, extra high performance, marine diesel engine cylinder oil. The outstanding performance of Mobilgard 5100 has been demonstrated at the elevated peak firing pressures and liner temperatures found in modern marine two stroke engines. It has an optimum viscosity of over 20 cSt. at 100ºC and low volatility to ensure excellent lubricant distribution and oil film retention. Through the use of unique synthetic thickener technology and a balanced formulation, the high viscosity and low volatility is attained with little or no use of bright stock which can create deposit formation due to poor thermal stability. Mobilgard 5100 has demonstrated outstanding ring and liner protection and cleanliness under sustained operation in highly corrosive engines that are under slow steaming conditions.

Features and Benefits

• Excellent corrosion protection in newer, more demanding engine types during slow steaming operation.

• Excellent thermal and oxidation stability can lead to reduced deposits and sludge formation. Cleaner engines can lead to reduced component wear rates.

• Exceptional anti-wear properties lead to potentially reduced liner and ring wear and excellent anti-scuffing control.

• Outstanding detergency capability leads to potentially cleaner pistons and liners and can help extend periods between overhauls.

Applications

• Marine crosshead engines
