I have relied on Amsoil products for many years, and never been disappointed.
Once my 4.6 is broken in, I will run Amisoil in it. I have heard that the Ford/Motorcraft/Autolite engine oil filter is one of the best, does anyone know that to be true? I have always run OEM Mopar oil filters on my Cummins equipped trucks because I heard that there was once filter failure troubles with some of the aftermarket oil filters and Cummins would not warranty if a filter that they did not approve of was used (they have a list of several non mopar filters that are approved) Does any one know if Ford does this as well?
