Engine build dates
I have a 2004 F-250 SD Crew Cab. The date on the valve cover driver side is Aug 15, 2003. Is this an 03 motor or an 04? VIN is 1FTNW20P14EA55370. Now, having asked this question, what improvements were made in the 04 build?
Thanks in advance for any and all replies.

they moved some components in th 04 changed the turbo a bit in other words they tweaked it

Hello,
I have a March 03 6.0 that doesn't get good fuel mileage, my VIN # is 1FTNW21P23EC50908. I was told by my local dealer it was because I was using 15-40 Delo oil. I was also told Ford won't do anything about poor fuel mileage. I get anywhere from 14-17 mpg, mostly around 15.2. I have almost 16,000 on it is there anything I can do to improve this?
I also am thinking of replacing my wife's 7.3 and am a little apprehensive of purchasing a new 6.0. I understand that the injection system is being revamped. Is this true?
Thank you,

If I'm not mistaken ford uses delo 400 and bottles it under motorcraft for diesel engine oil.
