Has anyone out there actually used motorcraft 5W20 full synthetic oil in their vehicle and are they pleased ? . Also it looks like Pennzoil Ultra Platinum might be an excellent oil ........... not available in Canada yet as far as I can determine. Has anyone in the US used the ultra platinum yet .........specifically the 5W20 full synthetic?

I'm sure someone has used Penzoil Ultra Premium, and had good results so far.
But the key words are "so far."
I think most people have had good results using full synthetic overall, but I think it's a bit premature for most Ex users (particularly owners of newer model Ex's) to offer real results on the use of full synthetic in their trucks. Maybe 2011 and 2012 owners can offer the best advice, but even then, the best advice can be given from someone who has used a particular brand, synthetic, and viscosity over several years.
I find it difficult, and particularly unbelieveable, for a person to attribute the improvement of a vehicle's performance or the prolonging of a vehicle's life, to the use of a specific brand, type, or viscosity of oil, without accounting for the almost unlimited other factors of a vehicle's life (environment, conditions, maintenance history, driving style, manufacturer defects, etc). Unless we dissect our engines every few months and study the effects of the oil, no one really knows what's happening until problems arise. And usually problems attributed to motor oil that appear right away, are likely due to using the wrong viscosity or outright bad oil.
I can say that I've used full synthetic for most of my adult driving life and have not suffered from any major problems. But can I solely attribute my good luck to the oil? Not necessarily. I'm sure folks who use standard oil and have excellent maintenance history have just as equal chance of prolonging the life of their cars as I do.
