Put a little over 6000 on the 2004 F150 FX 4 this summer. Got only 16 MPG in States with 85 octane gas but improved to a little over 18MPG when Gas was 87 Octane. Changed oil once. That was in Bend Oregon. Have been using 10-30 Mobil One for the last 5 changes. this last one was at 5000 miles. I am not using any oil at all. Dip stick was the same, oil not bad. 200,000 on the clock now. The 10-30 and the new VCT's that were installed before I left seem to have eliminated the tick. Have a code now. "Engine stumbles on first 1000 revolutions" Getting ready to get rid of the champions and put the new motorcraft 515's in. Think I am going to all new Coils and maybe injectors when I have the timing chain installed. Any place that sells the timing chain(Oem) for a good price? Any suggestions when I have this done? You know best prices and any good aftermarket stuff?
