PSC said it would take 7 days to deliver this product to us and it arrived on time in good shape. PSC also makes it easy to track your order. The amount of Mobil product we bought from PSC saved us $1000.00 over the next bidder. The Mobil products are always specified on the type equipment we install, and in my opinion, no other brand name product compares. Thanks PSC for your timely service.
