Hello I own a Cummins isx15, 2015, prostar
519,000 miles.
Oil consumption has increased to around 1 quart per 500 miles .
So 3200 miles I usually have to put 1.5 gallon of oil.
I went to the tech and had the engine front gasket replaced, I don’t have no leaks.
also had put a “no maintenance filter” to help with the blow by oil lost . I know with this type filter there will be some oil consumption but this really high.
I don’t have white,blue,black smoke.
Def deleted
engine runs at 200-230 oil temp
Water temp is always less than 200 F
should I add additives ? What type of oil should I use. ? Or is this freaking normal?
Thanks O/O

Sounds like your ready for an inframe. Get an oil sample ASAP. Put some Lucas in there and take it easy.
Xenergiserx Thanks this. -
Is the DPF still there?

Carbon compaction of the rings, which has caused streaking in the cylinders. Common problem in that year ISX. There is a special valvoline oil that is $100/gal. It has a detergent in it that reduces carbon compaction and supposed to reseal the rings. I’ve tried it once and actually was able to get another 50k miles or so.

Mine started using oil at 540k and progressively got worse until I had it tore down at 684k .
All 6 liners were polished , rings carbon packed and cam was shot.stuckinthemud Thanks this. -

Hell mine was using so much the last 10 months before the overhaul I quit changing the oil and spun a new filter on when the oil pressure started to drop a little .Isafarmboy, Farmtractor9900, AModelCat and 2 others Thank this.
