We have 5 samples to send out tomorrow. One for the used Explorer I bought (have no idea what it is or how long it was in there), two for the SVTP GT (factory oil with 1,500 miles on it and RP HPS 5w30 with 5,000 miles on it, 6,500 total miles on the car), and two more changes for the SVTP F-350 (both RP 15w40 with 5,000 miles on them and heavy towing).
