Hey guys, I just recently got some Amsoil signature 5w-50 and the recommended Amsoil filter to go with it. After I got everything done, I ran up town about an hour later to get some errands out of the way, and as soon as I came to my first stop after the car had been completely warmed up I noticed it was making this random tapping sound; almost reminds me of someone smacking two ball bearings together, or those little firecrackers you throw at the ground that snap. Needless to say this is fairly concerning, so I figured it couldn't hurt to see what you guys think is going on. A friend of mine was saying if the sound doesn't go away, to try going back to the Motorcraft filter, and maybe try something thinner, such as a 0w-40 or 5w-30. He thought that the oil might not be getting hot enough, and the tapping was possibly stemming from that. The car is a 2014 Track Pack GT. I would appreciate any thoughts on the matter from you guys. I've been a long time lurker, but this issue made me sign up.
