In my line of work, I deal with after hours approving or denying cost increases for a variety of PM and repair procedures for a large corporation. I just had a supplier call in for a cost increase approval for a PM service for a disel genset. They wanted $44/qt for 5W-30 synthetic oil. Even with 100% mark-up, I can't for the life of me think of a HDEO 5W-30 syn that would cost $20/qt. What could they be using??
