Mobil Delvac1 Synthetic high performance diesel engine oil contains high-quality synthetic base stocks and a unique super-high-performance component additive system. It provides outstanding high-temperature detergency and all-temperature dispersancy, with optimized resistance to thermal degradation and oxidation, wear, and corrosion.
Mobil Delvac 1 carries an SAE 5W-40 viscosity rating. It has all the advantages of an SAE 40 weight oil without the higher oil consumption inherent in multigrade oils that use very light-mineral oil base stocks. Because synthetics have higher boiling points than conventional oils, Mobil Delvac 1 does not evaporate as readily in the high-temperature piston ring area of turbo-charged diesel engines.
Mobil Delvac1 has the same viscosity as most SAE 40 oils at the high end of the temperature viscosity scale. However, because of its higher viscosity index and unique molecular structure, it provides a better protective film at higher temperatures than conventional oils. Mobil Delvac 1 remains fluid at sub-zero temperatures as low as -54°C (-65°F) and provides rapid cold-engine start-ups and warm-ups.
Mobil Delvac1 can provide satisfactory lubrication at temperatures up to 100 degrees above the upper limit for conventional mineral oils. It is fully compatible with conventional heavy duty diesel and gasoline fleet engines. It also provides unsurpassed protection against soot related viscosity increases in low emission diesel engines.
Mobil Delvac 1 has long drain capability and can be extended in service far beyond the builder recommended drain interval in both diesel and gasoline engines. Consult your Mobil representative for specific recommendations.
Mobil Delvac1 will provide outstanding wear protection and deposit control in the most demanding diesel engines of Cummins, Caterpillar, Mack, Navistar, Detroit Diesel, and others. It is balanced to provide optimum engine life until overhaul, in both high-loaded, thermally stressed diesel engines and units operating at lower speeds in pickup-and-delivery service.
Mobil Delvac1 exceeds the requirements of:

- Detroit Diesel Closed Crankcase Application TSB 01-TS-07
- Caterpillar deposit performance
- 2.0% distillation at 700°F
Applications
Mobil Delvac1 is recommended for diesel- and gasoline-powered fleet vehicles, such as over-the-road, off-the-road, truck rental, pickup-and- delivery, utility, and school bus fleets. Mobil Delvac1 is capable of providing fuel economy benefits of up to 3% and more in heavy duty diesel engines, with as much as a 40% reduction in oil make-up in over-the-road service.
When Mobil Delvac1 is used in an engine for the first time, no system preparation is necessary other than proper draining and installation of a new filter. In an emergency, conventional oil can be used as make-up for Mobil Delvac1, but such mixing may lower the performance of Mobil Delvac1. Do not dilute crankcase oil with gasoline or kerosene in cold weather. The diluent will not improve cold cranking and may have an adverse effect on the performance of Mobil Delvac1.
In addition, Mobil Delvac 1 is recommended for extended drain performance in truck trailer-mounted refrigeration units.
