High performance heavy-duty diesel engine oil
Mobil Delvac 1 ESP is a fully synthetic, high performance heavy-duty diesel engine oil that helps extend engine life while providing long drain capability and potential fuel economy for modern diesel engines operating in severe applications.
Mobil Delvac 1 ESP maintains outstanding performance at significantly higher temperatures than other high-performance diesel engine oils and with its long drain capability potentially can help increase operating efficiency and lower overall cost. It is also fully compatible with conventional oils.
We recommend it for use in a wide range of heavy-duty applications and operating environments, such as:
All super high performance diesel applications, including modern low emission engine designs with Exhaust Gas Recirculation (EGR), After treatment systems with Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs)
On-highway engines operating in both high-speed/high-load and stop-and-go conditions
Off-highway engines operating in severe low-speed/heavy-load conditions
Virtually all diesel-powered equipment from American and European equipment builders
High-performance gasoline engines and mixed fleets
Refrigeration units
