I recently bought an 18 Mustang GT with the 5.0 and many people are having ticking issues already. I am looking to prevent this. In many cases, this is a bottom end problem causing cylinder wear. There are quite a few guys saying Ceratec quietened the engine down. I'm looking to get some suggestions on a good additive that will reduce friction and provide a good layer of film that is resistant to high pressure/sheering without having any detrimental effects or corrosion issues.
