Duramax Diesel Oil selection & Oil adjust Procedures

Engine oil is exposed to too much conditions, being supplied as both a lubricant and also coolant inside the engine. Exposure to too much pressure, heat, and also contaminants such as exhaust soot and also diesel fuel degrade the chemical and also mechanical properties, necessitating regular oil changes. Engine oil should be changed every 10,000 miles or as indicated by the instrument swarm display. Regular towing, idling, and severe climate driving will certainly necessitate more frequent service.

Duramax Engine Oil Selection

There is no reason nor excuse not to usage a full artificial motor oil. Man-made oils are far superior to standard petroleum based engine oils and exhibit better resilience to chemical, thermal, and also mechanical breakdown. This translates into better protection against coking/breakdown of oil carry out to heat, shear resulting from too much pressures produced by moving parts, and oil air pollution resulting indigenous exhaust soot and fuel dilution.

We extremely recommend Amsoil"s line of full synthetic, diesel particular engine oil for all Duramax diesels. For much more information ~ above Amsoil"s artificial engine oil, see: Amsoil Signature collection Max-duty diesel oil (top tier product line) and/or Amsoil heavy Duty diesel oil (up to 4 times higher wear security than taken into consideration acceptable by present standards).

Engine Oil Viscosity

Temperature Range

SAE 15W-40

Ambient temperature > 0° F (preferred viscosity within temp range)

SAE 5W-40

Ambient temperature

Note that an SAE 15W-40 motor oil is recommended for all vehicles operation in approximately temperatures higher than 0° F, and SAE 5W-40 is forced when operation in temperatures reduced than 0° F. SAE 10W-30 is provided as one acceptable alternative for particular model year trucks, but it is not advised no one recommended.

• 10 quarts that engine oil and a new oil filter are essential to perform an oil change. We additionally recommend transforming the drainpipe plug every few oil alters as the seal often tends to degrade with age. In ~ Amsoil hefty Duty 15W-40 full synthetic engine oil for every Duramax diesel applications, or Amsoil hefty Duty 5W-40 full man-made engine oil because that cold weather operation.
