What Type of Oil Does a Freightliner Cascadia Need?

Updated April 12, 2024 by SearchForParts.com

The Cascadias come with so many different possible engines such as the Caterpillar C15 14.6L, Cummins ISX, Detroit Diesel 60 Series 14.0L, Detroit Diesel DD15, Detroit Diesel DD13 12.8L, DD16 15.6L, or the 14.8L Mercedes-Benz MBE4000 12.8L. In our personal experience when assisting customers, the variety of so many engines available can get a bit confusing when looking for a compatible oil and filter to protect your Freightliner. Some years may have a different engine as well.

For example, the 2013 may have a DD15 instead of a DD13 (we searched and found that this is possible since some are for sale with this engine type). Since we want to avoid any confusion when searching for the type of oil you need by year, we will list the oil needed by engine below and give you tips and ways to search for the exact engine. Our team has made it easy for you to find resources to look up your engine type, oil, and a compatible filter! We hope you find this helpful since everything you need to know is here to find out how to discover what kind of engine you have (we have a video link below).
