Motor oil is the lifeblood of her engine, giving lubrication and also cooling come a complicated system of quick moving mechanical components under far-reaching load. Regimen oil transforms ensure that old, damaged down engine oil is replaced before it loses its chemical and also mechanical properties, for this reason maximizing protection versus wear. Organization intervals vary in between 12v, 24v, and 24v usual rail Cummins engines (see schedule below). Always follow the manufacturers said oil change interval and adhere to the alternative "severe duty" schedule if you fulfill 1 or much more of the requirements.

5.9L Cummins Engine Oil

All 5.9L Cummins turbodiesels (6BT and also ISB) attribute a 12 quart oil capacity (with filter change) and also share the very same oil filter. Engine oil must be replaced per the oil adjust interval chart below using the ideal viscosity listed in the applicable graph below. Overfilling or underfilling the crankcase may result in oil aeration and compromised oil pressure. Always verify oil level on dipstick after running engine and permitting to cool for 15 minutes (oil in the height of the engine must drain earlier into the crankcase prior to checking oil fill level). No Cummins nor Chrysler recommend the usage of a supplemental oil additive in 5.9L diesel engines. A high quality, synthetic engine oil is encourage for every engines. Constantly fill the oil filter with roughly 1 quart the clean engine oil before installing, i m sorry will assist prevent dried starts and ensure oil push builds easily after transforming the oil.

5.9L Cummins Oil change Intervals

Severe organization conditions encompass towing, hauling, control in stop-and-go traffic, taking frequent quick trips, operation in warm weather, operation in exceptionally cold weather, and also frequent durations of extreme idling; always following the organization interval that applies to your operating conditions. Most vehicles will fall under the severe organization category, uneven your van is used for the sole purpose of commuting and also your course sees restricted city driving.

Fleetguard is Cummins" organization parts brand and is the recommended replacement oil filter for every Cummins turbodiesels; protect against cheap aftermarket filters. Change the engine oil pan drainpipe plug when the edges of the head start to show signs of wear or the gasket establishes a leak. Replace the oil to fill cap as soon as it starts to present signs of degradation to prevent particles/pieces from dislodging and falling into the crankcase.

Diesel Hub recommends the adhering to Amsoil commodities for Dodge lamb models equipped through the 5.9L Cummins turbodiesel:


Amsoil Max Duty Signature series 5W-40 diesel oil Premium cold weather oil for maximum engine protection


Amsoil man-made engine oils offer:

• superior protection against fuel dilution and also oil consumption

• exceptional resilience against thermal, mechanical, and chemical breakdown of engine oil

• boosted oil flow and engine security in sub-zero temperatures and during cold starts

Amsoil is a top manufacturer of synthetic oils and lubricants, consisting of a heat of engine oil engineered to fulfill the stringent demands particular to diesel engines.


Synthetic engine oil is superior in every way, shape, and type than conventional petroleum based engine oils. Fabricated motor oil attributes a significantly higher resistance to heat breakdown, chemical break down (contamination from fuel dilution and exhaust soot), and mechanical break down (shear). It is backwards compatible with ALL engines nevertheless of age and type.

• Park the vehicle, set the parking brake, and permit the engine come cool for ~ 1 hour before changing the motor oil.

• ar a an ideal drain pan (minimum 12 quart capacity) listed below the engine oil pan drainpipe plug.
