I would change my oil on this every 3000 just like my old 6.9. This is the first oil change I have done on the stroker. so I will check it 3000 miles from now. It has 61,000 miles on it. Which to me, is a baby diesel. It hasn't even reached it's peak potential yet. I also have plans for programmers and exhaust and air intake and all those other things. But yah cant build a good strong truck with a weak foundation. So I am going to make sure the truck itself is built to the hilt and proven before i start adding power to it. I wanna do some other stuff like a mag hytec trans pan and diff covers and all that other funky stuff. Make sure all the normal levels are level. Next will be a power train service. Making sure the trans, transfer case and differentials AS WELL as u joints, if greasable are all takin care of. I am also going to have it detailed before winter so it's all nice nice.
