[QUOTE="Atsah, post: 346813, member: 186"] Oil, If your going to use conventional oil 15W40, Motorcraft is what I used with good results. If your going to use a synthetic 5W40, Valveline extreme blue is good oil. I would stay away from Rotella oil in the 6.0. Mobil 1 5W40 is also good oil as is Amsoil.. If you do run a 5W40 oil you can use it year round, if you use a 15W40 in the spring summer and fall, I would recommend a HD 10W30 weight in the winter. Oil = 15qt's with the filter change. Motorcraft or Racor filters You have TWO fuel filters, one near your oil filter housing and one on the framerail under the drives seat. No enough, old burnt oil in a 6.0 with fuel filters that have not been changed for a long time will cause serious problems in a 6.0 to say the least. Fuel filters should be replaced every other oil change.. Considering your second to last post, If I were you, I wouldn't even be trying to start the truck without changing the oil and fuel filters, just to elimate that being an issue to start with.. If the oil is low, burnt and old, that may very well be what is causing your issues to begin with.. The sooner you change the oil and change your filters, the better.. Good quality clean oil at all times is essential for a 6.0 to run correctly.. [/QUOTE]
