Updated on November 15th, 2022 by SearchForParts.com staff

In this article, we will discuss the M2 Freightliner equipped with a Cummins ISB 6.7L engine and the capacity in quarts for each truck by year and model. If you own a Freightliner or have a fleet of them, great choice and a great semi! We will list as much detail as possible regarding the oil for the engine sorted in an easy-to-read table including the viscosity. Although in general, most sources say 12 quarts for the Freightliner M2 106, the best way to check is by searching your engine on the Cummin’s website for the oil capacity.

For your convenience, the link is below, and on their site, they provide more information on how to find the number. After looking up the engine please review our line of synthetic oil products for your semi-tractor trailer below. We even have a top filter to go along with the synthetic oil for the Cummins ISB 6.7L engine even if it is not a Freightliner M2.

For years between 2007 through 2016, most Freightliners that have a Cummins ISB 6.7L engine will need 3 gallons or 12 quarts of oil with a filter. Please check your engine’s 8-digit serial number for the owner’s manual to confirm before changing the oil. The 8-digit serial number can be found on the engine’s dataplate which is on the rocker cover or on the side gear housing. Search Your Cummins 6.7 Owner’s Manual Here
