Again, will ignore the snide remarks from our resident sales guy. My comment about my personal warranty carefree lifestyle is that I've already gone to the "dark side" by using Rotella T6 5W-40 in my engine. Clearly not what's recommended by FCA, but I'm comfortable with it based on the other certifications it has and I had a fair amount left over from my Audi A8L maintenance. The difference here is that the cost of having to drop a new engine in my car wouldn't even introduce statistical noise into my financial situation. That's probably not the case for a lot of people.
