Why Your Number May Differ

Cummins B6.7 oil capacity is not always one fixed number. It can change by model year, vehicle setup, and oil-pan configuration, so use the row that matches your vehicle before refilling.

warningBefore You Fill
Add about 0.5 qt less than the listed capacity first, start the engine briefly, wait a few minutes, then verify with the dipstick and top off gradually. Do not rely on a generic engine answer if your vehicle is a different series, chassis-cab, medium-duty, or special-package configuration.
