"If SAE 0W-20 is not available, SAE 5W-20 oil may be used. However, it must be replaced with SAE 0W-20 at the next oil change."
I want to know what's up with that ^^^ statement. Either 5W-20 is going to grenade the motor or it isn't. Is there some sort of "counter" in the engine that knows how many times in a row you used 5W-20?

I saved a copy of the 2001 letter sent by the EPA "allowing" Ford to use 5W-20 to qualify their engines for CAFE, and it basically states almost EXACTLY what edhackett wrote. "We will allow you to use 5W-20 but you have to be sure and tell all your dealers and the quick lubes to use it and print it very clearly on the oil cap and in your owner's manuals...blah, blah, etc..."
