Update (finally):
August 6, 2011 was the original date I started collecting. This was collected on February 6, 2013 for a total time collecting of 549 days.
Started collecting when the truck only had 15,280 miles. As of the collection date, the truck has 38,294 for a total mileage during collection of 23,014 miles.
Damn that's a lot of oil....
