Mobil Delvac 1 ESP 5W-40
Mobil Delvac 1 ESP 5W-40 is an advanced full synthetic diesel engine oil for hard-working engines, including compatible engines with emission-control systems. It supports engine cleanliness and protection during demanding operation.
Protection and performance
Mobil’s Delvac 1 ESP product information describes a low-ash formulation developed for engines with exhaust after-treatment equipment. Its additive system helps control deposits and protect against wear while supporting those emission systems.
Resistance to oxidation helps limit oil deterioration and deposit formation. Cold-temperature fluidity and pumpability support winter starting and lubrication, while corrosion resistance helps protect critical engine surfaces. Together, these properties support protection from cold startup through normal operation.
Choosing the right diesel oil
Compatibility depends on your diesel engine’s required viscosity and performance specifications. Ask our team whether Mobil Delvac 1 ESP 5W-40 meets those requirements, particularly for engines with exhaust after-treatment equipment.
Included with your oil change
Our full-service oil change includes up to five quarts of the selected diesel lubricant, a new oil filter, and a multi-point vehicle inspection. Windshield washer fluid, tire-pressure checks and adjustments as needed, and applicable chassis lubrication are included. Engines requiring more oil receive the additional quantity for an extra charge.
Recommended service interval
Mobil 1 Lube Express of Michigan recommends service up to 5,000 miles for this option. The displayed mileage is our shop recommendation; diesel maintenance needs vary with engine design and vehicle use. Follow the oil-change schedule and specifications required by your engine manufacturer.
