I am finally having the chance to drive the new 06 E350 with supreme spartan body on it. I am going to give it the proper break in time, but when I service, will Ford void the warrenty if I use Napa gold filters and amsoil synthetic? Also will Ford viod the warrenty if I were to install a Pyrometer? I was going to call my dealer and see how strict they are about gauges, and the oil. You want to talk about a tight fit, there is absolutely no room under the hood! Basically all the oil checks and fills are right there, but you can't even see the block from the hood. I pulled the "dog house" in the cab and it is very tight there too. I will post some pics as soon as I can figure out how to get them from my digi camera to the computer.
