Mobil Delvac 1™

Premium performance heavy duty diesel engine oil

Mobil Delvac 1 high speed lubricants are high-performance synthetic diesel engine oils designed to help extend engine life and protect components at high temperatures. Mobil Delvac 1™ ESP and Mobil Delvac 1™ SHC are highly suited to modern, high-output marine engines.

With over 30 years of specialist synthetic formulation expertise behind
them, ExxonMobil’s research and development engineers have created the
Mobil Delvac 1 synthetic range with state of the art technology to deliver exceptional performance in the latest high performance engine designs.

Outstanding wear protection
Mobil Delvac 1 synthetic lubricants offer outstanding wear protection with increased stability at high temperatures*. That means they have better resistance to thermal degradation and oxidation* that can lead to sludge formation, deposit build-up and viscosity breakdown.

Extended Oil Drain Intervals
Mobil Delvac 1 ESP delivers up to ten times the drain intervals**, which means less vessel downtime, more efficient operations and reduced labour costs associated with oil changes and waste oil disposal.

* Compared with equivalent mineral oils
** Based upon field testing of Mobil Delvac 1 ESP 5W-40 in high-speed, 4-stroke marine engines, and compared with conventional heavy-duty diesel engine oil. Actual results may vary by engine type, maintenance, operating conditions, environment and prior lubricant use. Drain intervals should be established through routine used oil analysis.
