How much oil are your cummins diesels using between oil changes? My first 3000 miles I used none off the stick, then I put in Mobil Delvac 15W40 and now with 3000 miles I'm down about 1/4 inch on the stick off full. Thanks, Chad

 

37K on the clock and have yet to burn any oil.

sometimes when the engine gets nice and hot you'll have some oil blow out of the breather(totaly normal) if your towing.

 

171,000+ and all I lose is the amount over the full line on the dipstik. And that blows out the breather tubes. My motor doesn't leak any oil...........


Good luck with your ride.

 

burns/ blows out the breather 1qt to 5000miles in the winter. doesn't lose any in the summer.
