MotorKote on Cummins ISX?

Doubt it would help, maybe time for rings.

 

Doesn't Cummins have a special oil developed to help remove carbon packing on the rings? I'd put more faith in what is recommended by the engine manufacturer over any snake oil additives.

 

Inframe beats motorkote every time. Don't you OO's make the BIG BUCKS!? All of us company drivers just work for chump change.

 

It won't do anything but make a mess if you put it on it. If you put it in the engine it might help.

 

Made by valvoline, Cummins sells in at the Cummins shops

 

motorkote is not a thick oil. its super thin. lucas would be a better choice.

 

I would not use any oil additives.
Major producers spend ridiculously large sums of money each year on R and D. Doubt some random snake oil will be better than that.
Like others have said, go get the special Valvoline Premium Blue Restore oil from Cummins specifically engineered by Cummins and a major oil company to solve your issue. Get the recommended filter as well. The oil is unfortunately somewhat expensive, however it has some pretty exotic ingredients that drive the cost way up. Make sure you get the Restore, they have like Extreme but thats not the one.
Otherwise you are looking at a rebuild.

 

Root issue is carbon packing. Pistons/ liners need to get updated to arp style liners.
Vavoline did have a special oil to fix/ patch the issue, it has since been discontinued.

 

They should make enough for an inframe,
