    Oil life
    By  ROBERT,  a  Verified Buyer  from  Edgewater,(Maryland)   on  September 13, 2021

    Describe the issue

    This oil seems to break down at approximately 125 hours. The oil turned black and got really thin. This caused my oil pressure to drop 7-10 lbs. I’m going to give it one more try before I witch brands. This oil is being used in a Cummins 5.9QSB that is in my boat and they recommend 250 hour oil changes. This oil will never make it that long. Thank you for your time.
    Bottom Line
    Yes, I would recommend this to a friend.

    Run this in my 2007 pre-DEF engine since new. First ran for 15K and then tested results with SOAP analysis—results were excellent. Now run the oil at least 30K miles, changing filters every 15K. Good MPG and cold wx starts to 0 degrees F. Highly recommend for towing and tough engine use conditions.

    Great diesel oil for pre-dpf engines
    By  ALEK J,  a  Verified Buyer  from  NC  on  July 30, 2021

    Describe the issue

    I've been using this oil nearly exclusively for the past 15 years in my 2006 Duramax. I average 35,000 miles between oil changes and monitor every 10-12k miles when I change the filters. Amsoil has always provided great protection for my engine. The high TBN lets me use the oil longer than any conventional oil and my truck is running great with 256,000+ miles. Great oil, I'll continue to use it.
    Bottom Line
    Yes, I would recommend this to a friend.

    Going for 50,000 mi
    By  ALEK J,  a  Verified Buyer  from  NC  on  July 11, 2021

    Describe the issue

    I’ve been using this oil for 15 years with excellent results. High TBN promotes its use for extended oil change intervals. I’ve run several 40,000 mi intervals. Just added the PPE oil pan and filter adding an extra 2qt capacity to the engine, and draining 99% of the old oil. Hoping to get 50,000 mi on this oil!
    Bottom Line
    Yes, I would recommend this to a friend.
