    Describe the issue

    Great oil for old cars. Drained oil for oil change and oil looked great probably could have continued using it for a few thousand more miles. But I’m old school and still like to change my oil every 3000 miles or once a year depending on what comes first for my classic cars.
    Bottom Line
    Yes, I would recommend this to a friend.
