The truck started with no problems (but it was above 70 outside today). I will report back when it is a "cold start", basically below 50 F.
Still have problems at WOT (lots of BLUE smoke) but I am working on that.

So it is an improvement .. I am glad it actually did something in the right direction. Evryone on here was kind of cutting me down about it, except for you LOCO .. thanks and I hope it actually works.Its amazing that thin(synthetic) oil flow might be the cause of it. and incase you are under warranty(100,000 engine) don't tell your dealer you were running synthetic, because depending on how hard up they are they might call you out on that if something happens. by the way, where you from. your having weather like me. I am in Tennessee
