*Assuming normal duty cycle
**OEM-supplied, intervals may vary
***If engine is equipped with an optional coolant filter, it will need to be replaced at the same intervals as the oil filter.
****Extended Coolant drian/flush/fill intervals may be followed when certain requirements are met. For more information on these requirements, refer to the Cummins Coolant Requirements and Maintenance Service, Bulletin 3666132.
Cummins recommends the use of a high quality, diesel engine oil, such as Valvoline Premium Blue™ or Valvoline Premium Blue Extreme Life™ or their equivalents, and high quality filters such as Fleetguard® or their equivalents.
ReplyDeleteI typically use the Baldwin Filter brand for my Cummins applications, OEM CAT for the CAT Engines and OEM Mercedes Benz for the MBE900 Series.
When you spec. your oil for purchase or bid, make sure it MEETS Cummins Spec. CES 20081 API CJ-4. Some less expensive oils will say designed to meet, or not show both numbers. Your engine is easily worth about 20 to 30K, spend the money on quality motor oil.
I currently use MOBIL 1300 15w40. I have had extended drains, Oil test after after oil test with Oil Sample history, never an issue with this brand.
Synthetic Oils
ReplyDeleteUse of synthetic engine oils (those made with API Group 3 or Group 4 Base Stocks) is permitted, subject to the same performance and viscosity limitations of petroleum (mineral) based engine oils. The same oil change intervals must be applied to synthetic oils that are applied to petroleum (mineral) based engine oils.
Re-Refined Oils
Re-refined lubricating oils can be used in Cummins® engines, if they have an API license signifying they have been tested and meet the minimum standards for that quality level. It is important to be certain these oils are actually re-refined and not just reclaimed. Re-refined oils have been treated to remove additives and wear debris, distilled, and refortified with additives.
Friction Modifiers
Do not use oils containing supplemental friction modifiers in Cummins® diesel engines, unless the oil supplier can provide evidence of satisfactory performance in Cummins™ engines. Obtain the oil supplier's commitment that they will make sure the oil is satisfactory or do not use the product.
Break-In Oils
Special break-in oils are not recommended for use in new or rebuilt Cummins® engines. Use the same lubricating oil that will be used during normal engine operation.
Drain Intervals
Correct oil and filter change intervals must be maintained for each specific Cummins® engine model. A sharp increase in component wear and damage can occur if excessive oil drain intervals are followed. See the appropriate Operation and Maintenance Manual to determine the appropriate oil drain interval for your engine and application.
Monograde Oils
Use of monograde oils can affect engine oil control. Shortened drain intervals might be required with monograde oils, as determined by close monitoring of the oil condition with scheduled oil sampling.
Non-Classified Oils
In some parts of the world, oils meeting present API, ACEA, or JAMA classifications might not be available. Advice may be required when using non-classified oils. Oil suitability and service intervals can be determined by close monitoring of the oil condition with scheduled oil sampling.
