Thanks again for all your help and suggestions. Lesson learned tryed to do extra on the oil change with the additive. next oil change I do think I will go Synthetic as it does sound like the way to go.
someone said the synthetic is better in the winter..above..so with the powerstroke u can go back to the regular oil ?...or once u run the synthetic u have to use it all the time ?

I stay with the synthetic year round..My engine used to romp, romp in the middle of the summer time (truck in the garage at night) when i used the dino 15W40. No problems now with synthetic... I will never go back to dino..
same thing happened to me when i tried lucas. first start of the day, my truck would have the romps and run a little funny until it warmed up. Didnt matter that it was 90* outside. Went back to 15-40 and all is fine.
I must say though, I wish walmart carried the rotella 5-40 synthetic so I could try it out.

You can change from synthetic 5W-40 to regular and visa versa. For example, many folks run the Shell Rotella synthetic 5W-40 during the winter then change back to Delo 400 15W-40 during the warmer months.
Wal-mart doesnt have it available for your oil change. I always take my vehicles to walmart cuz the price is just hard to beat. $41 and change gets the oil changed in my truck right now. Last time I priced it, I could barely get a 5 gallon jug of 15-40 for that price. I keep asking, but until they have it, i am going to stick with straight 15-40.
I run the regular rotella in my excursion and my 1984 300 turbo diesel benz...my next oil change ill try the synthetic in the truck...by the way COSTCO is where I get my oil...its a wholesale place...and I believe they carry the synthetic also..
