Mobil Delvac 1™ LE 5W-30 synthetic diesel

Mobil Delvac 1™ LE 5W-30 fully synthetic diesel engine oil is especially suitable for heavy-duty diesel engines using low sulphur fuels and biodiesel fuel formulations – including main propulsion engines for lifeboats and tugs, as well as generators and winch engines.

It is formulated to withstand extreme operating conditions found in modern engines. This includes engines with inter-coolers and turbochargers, as well as older, naturally aspirated engines.

Mobil Delvac 1 LE 5W-30 engine oil may offer:

• Outstanding wear protection for prolonged engine life
• Improved fuel economy potential*
• Extended drain intervals, enabling fewer oil changes and less oil disposal
• Excellent low-temperature performance, enabling easier startup in cold weather

*Compared with conventional alternatives.

High output, low emissions engines significantly increase demands on engine lubricants. Tighter engine design reduces oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Thermal stresses on the lubricant are increased with the use of inter-coolers and turbochargers. Higher fuel injection and cylinder pressures and retarded timing improve burn efficiency, but also increase engine temperatures, volatility, and soot loading of the oil. The advanced technology in Mobil Delvac 1 LE 5W-30 delivers exceptional performance in these severe conditions while protecting emissions systems.
