ISX CM2350 Oil Usage and Fuel Economy - Suggestions?

[ynot]

Pull the compressor outlet pipe off the turbo, too check for oil leaking. You can also pull the lines off the air compressor they've been known too leak oil as well. It's a 14 motor so it should have the updated pistons too stop carbon packing, so hopefully that's not your problem cause the only way too fix that is a rebuild.

Your oil usage seems extreme but maybe this could be part of the problem... if the truck was using a lighter an or different oil, changing too shall has changed it wear pattern an will take a couple oil changes too settle in
