Okay guys got another one for you, this truck I bought brand new in 2011 with the intentions of it not seeing a lot of miles that's why I have my 250, the truck sees mainly highway miles I pull a bass boat to Texas twice a year and that's about all the towing it see's maybe a 28 foot boat every now and then. Truck has 70,000 miles on it and is paid for so I'm just going to keep it, I've been running Oreilly auto parts Dino oil with a motorcraft filter and change it every 5,000. I feel foolish for running cheap oil but I had the intentions of the truck not seeing a lot of miles. What's the best all around oil for this truck? I have a buddy that runs gulf pride syntheic blend and loves it. What's your alls thoughs?
