[QUOTE="01cobravortech, post: 13299640, member: 14885"] In the process right now of getting a 15k sample on my Amsoil 10W-30 SS oil. The fears about going to a different weight than Ford recommends...are just not substantiated. In fact, some of the brands that some folks use simply aren't as high quality as some think. I've used Amsoil 0W-30 in the winter before and I'm strictly staying with their 10W-30. And the UOAs I continue to do on these long intervals between oil changes, show outstanding wear protection and they show that I can run their oil beyond ranges that most people wouldn't even dare to go to...out of unsubstantiated fear mongering from the 3k oil change crowd.
