AMSOIL diesel oil guide for trucks, vans, SUVs and diesel engines<\/figcaption><\/figure>\n

For the 2024 Ram 2500 Pickup equipped with the 6.7L 6-cylinder L ETL L Diesel Turbo engine, the oil capacity is 12 quarts (with filter). The recommended viscosity is 10W-30 for temperatures above -18\u00b0C and 5W-40 for temperatures below -18\u00b0C. AMSOIL recommends using Signature Series 10W-30 100% Synthetic Max-Duty Diesel Oil<\/a> (DTTQT-EA<\/a>) paired with an AMSOIL oil filter<\/a> for optimal protection.<\/p>\n

What oil does a 2024 Ram 2500 6.7L Diesel take?<\/h2>\n

The 2024 Ram 2500 with the 6.7L diesel engine requires an oil grade of SEO39. For optimal performance, use 10W-30 viscosity when operating in temperatures above -18\u00b0C. If you are operating in extreme cold (below -18\u00b0C), a 5W-40 viscosity is recommended to ensure proper lubrication.<\/p>\n

AMSOIL product recommendations<\/h2>\n

Based on the specific requirements of your 6.7L Cummins diesel engine, AMSOIL provides several high-performance lubrication and filtration options to support heavy-duty operation.<\/p>\n

How much oil does it take with a filter change?<\/h3>\n

The total capacity for the 6.7L diesel engine is 12 quarts when including the oil filter replacement. When performing an oil change, follow these steps: after filling, start the engine and let it idle for several minutes to check for leaks. Stop the engine and wait 30 minutes to allow the oil to drain back into the pan before re-checking the level.<\/p>\n

Diesel maintenance notes for this vehicle<\/h2>\n

Maintaining a Cummins diesel engine requires attention to filtration and fluid integrity. Because these engines utilize turbocharging and complex emission systems, using high-quality lubricants is essential to manage soot levels and protect turbocharger components. Always verify specific service intervals against your owner’s manual or official Stellantis documentation.<\/p>\n

Common diesel oil-related concerns and how AMSOIL products may help<\/h2>\n
