    I have a cummins isx 2012, and I pull 55 tons gross. Which engine oil should I use, regular T4 or semi synthetic? And which company is better rotella or delo?

    And finally after how many kms should I change the oil, when using regular t4 and when using semi synthetic.

    Lots of variables there. I'd say pulling those loads 20k miles on dino oil, 40k on synthetic.

    Synthetics definitely have advantages. May or may not be worth it. If I went synthetic, I wouldn't use a blend

    I'm Driving a 2012 isx.

    Delo400 non synthetic is what it likes.

    Motor is quiet and oil consumption is the least. It currently has a leak. Delo slows it down considerably.

    Another company I see occasionally. Uses Rotella. Their motors aren't very quiet.

    Don't even think about using mobil. The motor will sound like a tank ready to blow up.
