How Many Gallons of Oil Does a 2021 6.7 Cummins Take?

A 2021 6.7 Cummins engine takes approximately 11-13 gallons of oil, depending on the exact model and configuration. For most applications, a 12 or 13 gallon capacity is recommended since this provides enough oil to ensure proper lubrication for all of the moving parts within the engine. It’s important to make sure that the oil filter and other components are compatible with the size of your specific engine before you purchase any additional oil because not all engines have identical specifications.

Additionally, it’s essential to frequently check and change your vehicle’s oil in order to prevent wear and tear from occurring over time which can cause costly repairs down the line.

What Oil Does a 2021 Ram 2500 6.4 Hemi Take?

The 2021 Ram 2500 6.4 Hemi requires 5W-20 oil for optimal performance and engine longevity. This type of oil is specifically designed to protect your engine from high temperatures, wear and tear, as well as being able to withstand the high compression of a V8 engine like the 6.4 Hemi in your Ram truck. When you take your truck in for an oil change, make sure that you request 5W-20 synthetic motor oil; this will provide superior protection against sludge build up while also providing better fuel economy than conventional oils due to its low viscosity.

It’s important to note that the manufacturer recommends using only Mopar or Pennzoil brand motor oils with the 6.4 Hemi – any other brands may not meet all specifications set by Chrysler/Fiat Chrysler Automobiles (FCA). Additionally, it’s best practice to use a full synthetic motor oil when changing out your vehicle’s fluids every 3 months or 5000 miles (whichever comes first) so that you can ensure maximum performance and reliability from your Ram truck’s powerful engine!
