With it telling you three different oil types I would contact a dealer. That would be the safest bet with the most accurate answer. If push came to shove I would follow the owners manual but we have no idea what's been done to your truck in the past. Could have had a different motor installed etc.
Edit: the dealer can also pull ALL the information on your truck by the vin number.
