    Cummins suggests changing the oil at high mileage intervals based on mpg for x15 engines. Seems like a lot of miles on an oil change. What is everyone else doing? A lot of you will probably say do it more often but don't want to if it can be prolonged safely.

    Every 3,000 miles. Seriously, changing engine oil more often doesn't really help it last longer but using the right oil and changing at the right intervals will make a HUGE difference on the wallet and help conservation.

    Well ask any ISX owner how their cams liked extended oil change intervals. I see no reason to trust what Cummins says for service intervals after that even with the X15 being a different engine.

    A defect on ONE engine does not dictate the laws of physics.

    Well if you think going 1,000+ hours on oil is ok, have at it. To me, 500 hours max. Oil and filtration have not advanced a whole lot in the last 10-15 years.

    Get you a bypass filtration system. Change filters every 12-15k. Send oil in for testing. Most go around 80-100k miles till it needs to be replaced

    80-100k? That's insane.

    You got pictures of the filtration system you put on? I would like to see how it looks since we have the same trucks.

    I do my ISX-

    Engine oil
    Oil, fuel, fuel water separator filters
    Chassis lube
    every 20,000

    $300 give or take.

    Coolant filter and air yearly.

    New camshaft installed = $5000 or 17 oil changes

    I'm at 700K miles
