    I had oil change done at local Speedco yesterday, did oil analysis as well which I could upload on here.
    According to oil analysis oil doesnt show any unusual wear, etc and Ive only had 15,000 miles on it. Its 15w40 Delo 400 that I run in Cummins ISX15 @483K miles on it.
    I was thinking should I extend it to 20K miles and do another oil test. Previously as company truck they changed oil @30k mile intervals on this truck but I've noticed oil consumption after @20K miles so I think oil would degrade at 20K miles and this is probably when oil should be changed.

    Every truck engine and every warranty stipulates different intervals. Factors such as type of use, road/off road, idling time can contribute to the longevity or lack of when it comes to pm service life.

    Filters are another aspect. Some may need a fuel, engine coolant, water separator filter with every service or every other service.

    Your best bet, if the engine is still under warranty is to follow the manufacturers guidelines so as to not void the warranty.

    Doing PM services way before they are due is a good way to spend extra money that you don't need to.

    I change it 12 to 18 k. At 18k the oil pressure drops on my engine running down the road. I shoot for 15 k. It's cheap and why have dirty oil running through the turbo? If I'm sitting in the Dakotas looking for a load out, then I'll change it early at 12k..

    Once your oil hits 5k, it is dirty.

    It is the additives that break down that is a concern. Oil doesn't.

    One reason why I install bypass systems on all the trucks is to keep it cleaner than it would normally be plus allows me to add additives back into the oil without the need of changing it.

    Sure, go ahead and extend those oil drain intervals.
    Let me know how that works out for your ISX!

    The first thing you need to do is get a real oil sample done. Not Speedco, Petro, etc.
