Mobil Delvac 1™ SHC 5W-40

Mobil Delvac 1 SHC 5W-40 is a supreme performance, synthetic diesel engine oil that provides excellent lubrication including long drain capability, and long engine life for diesel engines operating in severe applications. 

The advanced technology behind this product delivers exceptional performance in turbo-charged as well as older naturally aspirated engines.  Mobil Delvac 1 SHC 5W-40 is recommended for use in a wide range of heavy-duty applications and operating environments found in trucking, mining, construction, agriculture and marine.

Mobil Delvac 1 SHC 5W-40 has all the advantages of an SAE 40 weight oil without the higher oil consumption inherent in multigrade oils that use very light base stocks to achieve low temperature performance.  Because of the unique molecular structure of the synthetic base stocks used, combined with a highly responsive additive system, Mobil Delvac 1 SHC 5W-40 does not volatilise as readily in the high temperature ring-belt area of the pistons of turbocharged engines.  It also provides stronger lubrication film strength at higher temperatures and low temperature performance reducing oil consumption and wear.


Modern high output diesel engines run hotter than older engines which significantly increases the demands on engine lubricants.  Current tighter engine designs reduce oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Top piston rings are located higher bringing the oil film closer to the combustion chamber where temperatures increase thermal stress on the lubricant.  Mobil Delvac 1 SHC 5W-40 can provide satisfactory lubrication at temperatures significantly higher than the upper limit for other extra high performance diesel engine oils.  It is also fully compatible with conventional mineral oils.  The key benefits include:

FeaturesAdvantages and Potential Benefits
