I have a 2015 DX3 with the ISL Cummins and 11,600 miles on it. My engine is using some oil, about a quart every 1500 miles, just curious if anyone else is noticing any oil usage.

It seems looking on line that some ISL / ISC engines use oil and some don't. I bought it used with 6,000 miles on it and since I could not get a good answer from the dealer when the oil was changed I took it to a Freightliner dealer and had a complete PM done. Initially after the oil change I didn't notice any loss but lately I have. I have one more local trip this coming weekend and then I'm going to get it PMed again so at that time I am going to question the Freightliner dealer and get it on record in case of future problems.
