i know when it comes to the parts for the 2.3 we ALL use motorcraft when its available. well what about motorcraft oil. in the "how many quarts w/ filter change" thread, it is obvious we prefer the motorcraft filter. everyone tells me to use mobil 1 or valvoline conventional oil to break in my 0 mile motor. well i cannot find mobil 1 conventional oil anywhere (AZ, bastards, wal-mart, ect.) they are all synthetic. and im sure there is better oil then bent valvolines or quaker shake. why not break my motor in w/ motorcraft 10w30? no one, when i asked, recomended this to use in my motor.
