Just did the first oil change (For me) on my '03 sport. Put the Fumoto oil valve on it, (I have the 'side discharge') and that thing is really gonna pay for itself in the future! I used about a half roll of paper towels cleaning everything up! Put in Mobil1 5-30 synth, Pure one filter and will do the Diff. with synthetic this week also. Anyone know how the Motorcraft filters test against Mobil1 or Pure one? I like the last two, but if I can save 3 bucks.... I did see that it has the anti-drainback valve on it, but wonder about the efficiency of it. Also, as this was the first time I've spent any real time under the truck, I noticed that the entire underside of the body is covered in foil-backed sound/heat proofing material. Are all the late models like this? Thoughts about adding any spray on undercoating? (More'so for noise) I'm officially in the 'Mature' (Old fart-BBQ_HOTDOGS ) group now and don't want a race truck, but rather a quiet-reliable one. Thoughts?
