Engine oil consumption

Never looked at the oil level when you drove a company truck? Did you never bother to look at tire pressures or brakes either?

You didnt even bother to tell us how many miles and hours are on your engine.

 

Quarts, I have never put a quart of oil in a truck engine.

 

Mandeep your engine needs rebuilt.

 

what year is your cummins isx ?

 

That’s a lot of oil.
My 2016 D13 with 430k Miles requires no additional oil between oil changes. 20k mile interval.

But then again I’ve heard Cummins is known to consume more oil than Volvo engines

 

If you're adding three or four gallons of oil between changes, unless there's a serious oil leak someplace, then you are ready for an in frame. It is not normal for a broken in motor to go through oil like that.
