ok I have an all stock 05 f250 with 6.0 Powerstroke. It has 125,000 miles. I live in North Ga. so the temperature around here is all over the board. I don't drive the truck daily so I only change the oil maybe twice a year.. Last time I went with the t6 5w40 syn.. I plan to change the oil fairly regularly 3,000-4,000 miles. My mechanic recommended that I use "cheaper oil" and change at least every 3,000 miles... He recommends Delo 15w40.. Thoughts??
I really just want everyone's opinion on what oil I should use because I don't like going long intervals but I don't know that I like the idea of not using " the best" .. Meaning I do like the idea of using Syn but is it a total waste at 3,000-4,000 miles... If I go with 15w40 it would probably be Delo or Delvac as those are cheap and available.
