RE: V10 8.0L MPG
One of my co workers keeps bragging that his 2001 diesel gets 20 mpg while my v 10 only gets about 10 mpg. He has now replaced somthing call a lift pump for a second time 2 x $3500 and one other expensive diesel specific item (I can't remember the name right now). I think he is into 8-9 grand in repairs for just the diesel parts. The repairs I've done to the V 10 engine: throttle position sensor $50, plugs about $70, K&N cold air intake $400, plus regular oil changes (I run full synthetic as it is good for an extra .5 mpg). That being said, I glad I live close to work and don't have to commute with it.
