Knock and Ping (new question, I promise)
I searched the threads for information on why the 5.4L has the engine knock and diesel sound and found several pieces of information, but I have a new question.
My local Ford dealership acknowledged the problem and that while it is annoying, it's not something that needs to be fixed. In fact, the service center recommended that I use 4 quarts of 40W and 2 quarts of 50W on my next oil change and that the noise problem would completely go away!
Any one have thoughts on this? I'd hate to use heavy weight oil and cause problems with the engine but since they made the recommendation, I'm considering doing it.
Thanks for the help and sorry this is so long.

40W and 50W in Ga!? Wow that's heavy. I'm in Phoenix, Az. and always use 5/25. Thought I was losing my mind until I read this. I have an '06 that I occasionally "think" I'm hearing a knock. I'll swap out a qt of heavier oil next oil change. Let me know how it works out!
