Yeah. If he has a Dodge V10 you have to understand the Ford V10 is a completely different animal. The Ford V10 is a modern 6.8L and the Dodge V10 is an older design 8.0L, so there's alot of difference in engine size for starters.
I've known a few guys who have/had Dodge V10s and none of them ever saw double digits for mileage. It was introduced in the early 1980s and is a low-revving, gas-sucking torque monster. The last version listed for 2003 commercial Dodge trucks was rated at 305hp/440lb-ft. Tell your pal not to bother wasting his $$ to get better mileage out of-it ain't gonna happen. The best way, like the other guy just said, is to change driving habits-keep the RPM under 2000, stay in OD as much as possible, avoid stop-n-go driving. Also start off easy from stop lights and eliminate as much weight as is feasible.
Driving my Ford V10 in that manner is the difference between me getting 10.5mpg and 12.5mpg for mixed driving. If I stay in OD on the highway I get over 14 easily and have gotten 15 on a few trips when I traveled at a constant speed long-distance. That's good mileage for a gas engine in a 6800lb pickup.
Take the V10 and wrap it in a Mustang or other small car - VOILA! Better MPG...

I'm trying to understand your question, are you deliberately misspelling and using bad grammer? I hope so. Did your oil change involve putting 5w20 back into the engine or did something thicker get put in? Thicker oil will cause more fuel consumption...

I have tried hevier oils and never seen a MPG change, right now I am running 20-50 for the summer and my MPG is the same as it has been.

Why in hell's name would you put a heavier oil in an '04? You are going to blow your warranty and any hopes of fuel conservation. Go back to the factory recommended 5w-20 or you are toast!!

I would not run 20-50 oil in my 04' V-10 !! Now why would you do that ?? I know 5-20 seems thin to what we use to run 20 yrs ago,,but man this is a new engine ment to run on 5-20,,,thats what they recomend, not 20-50 ,do what ya want I guess.
these all are tight tolence motors if you built a "old" style motor to the same tolerences you would use 5-20 oil in them too like some race cars
basiclly i would say your just grinding your cams down guess that will save gas (if your valves don't open as far)
i would say if your having a oil pressure problem and its hot try 5w30 or in bad cases 10w-30
i am not suited to a new verihickle if i had oiling problems with an `04 i would wax it up real good and shove it up the dealer's...well you get the point
