As a result, this product meets or exceeds the requirements of the latest API and ACEA industry specifications for diesel engine oils, as well as the requirements of many major American, and European engine manufacturers.

¹ Please refer to the owners handbook for OEM application requirements and oil drain intervals for your vehicle or equipment.

² Compared to an SAE 15W-40 engine oil. Actual savings are dependent on vehicle engine type, outside temperature, driving

conditions, and your current engine oil viscosity.

Features and Benefits

Mobil Delvac 1™ ESP 5W-40 is an outstanding lubricant solution for modern and latest engine technology equipped with emission after-treatment. It was developed by ExxonMobil to maintain unsurpassed oxidation stability³ while also delivering exceptional low temperature fluidity and pumpability for smooth starting in cold down to -35°C. This feature, in combination with the sophisticated additive system, ensures exceptional engine wear performance and supports long engine life. The low ash formulation protects at the same time all exhaust after-treatment devices to maintain cleaner air requirements. The advanced engine cleanliness performance prevents deposits and keeps the engine running like new for long and efficient engine life.

³ Based on PC-11 industry test data.
