Lets keep this on point without the name calling or other inflammatory remarks. I don't like using the edit button but I will again if this keeps up.

Kind of interesting what your average is, when I tracked out 2000 V10 DRW pulling our 5th wheel to Alaska we averaged 8.94 over the 11K mile trip with the trailer attached 95% of the time and when it wasn't it was in town driving no highway.

My towing is all short trip stop and go with a dump trailer.

 

I have a 2002 Ex 4wd w/3.73 285 75R16 and no mods. Recently returned from a 3400+ trip and averaged 12.8 for the trip hand calculated. I think the the worst tank was around 9 and the best was 13.6. Trip saw everything from plains to Rocky Mtns to desert. Of course I had hoped for better but was not surprised. However I was very disappointed in the performance climbing through the mountains.

 

Just got back from towing our TT to the Grand Canyon, averaged 9 mpg but for 300 miles we were not towing but did have 8 of us in the Sherpa at 70 mph and got 14 hand calc.

 

2010 6.8 V10, ZF6 manual, Super Crew 8' box, 4:10 limited grip rear 31,000 miles. Bone stock. Has been averaging 15MPG unloaded.

 

Hi all,

I run a 2000 V10 in Spain where standard fuel is 95 octane and premium is 98 octane. It also runs on lpg. 95 octane costs €1.40 a litre and LPG €0.77 a litre.

Without a trailer I get 15 mpg (US) on 95 octane and 13.5 on LPG. With a 10,000 lb trailer I get around 7.5 mpg on 95 octane and 6.6 mpg on LPG.

The above are generally steady at 56 mph, loaded or unloaded.

I have a 2005 6.0 psd too but love the V10 gasser

Andy, nice to see those full sized trucks working over there!
Just to avoid any confusion, EU 95 octane = US 91 Octane and EU 98 Octane = US 93 Octane, same fuels otherwise just a different testing method for the ratings.

 

Cheers Tom,

I had no idea about the difference in octane ratings, so that cleared up a bit of confusion for me. Is there any benefit to running 93 octane as opposed to 91 as it's around 9% more expensive?

Not really unless you have done some motor work that would require it like increased compression ratio or turbo/super charging it. 91 Octane is considered "Premium" fuel around here (some stations do offer a 93 Octane too), I normally run 87 but will fill it with 89 if I'm going to be towing in any mountains. I run an SCT tuner with tunes from Mike at 5 Star Tuning, running around town solo I use the 87 Economy tune, for flat land towing I use the 87 Performance tune and for pulling in the hills I run the 98 Performance tune. The tunes really do wake the truck up, transmission performance is much better and the fuel map and timing is adjusted to take advantage of the higher octane fuel. You may want to contact Mike and see if he could write a custom tune for you to take advantage of your local fuels.

 

I'm always in mountains, I get 10 empty and less towing. I won't look at towing numbers. California GAS is bad. I get better numbers with I get gas in Arizona.


The engine is smother they my wife's Passat. I have ZERO power train issues.

 

I just did a trip from Riverside Ca to Bay Area 880 miles round trip and I got about 13.1 mpg combined city and highway. 01 f250 crew cab short bed 4" lift and 35s on 3.73 gears only mod is K&N intake and 215k miles on original v10.

 

I'm not on here much anymore, but I recently moved from Northern California to Southern Oregon and my trusty '04 Lariat went from high 11's to mid 14's after the move. For one thing, the gas is MUCH better here, plus I live in the Rogue River area, which is flatter. In fact, a couple weeks ago I filled up in Central Point where I work and the next tank calculated out to 15+. I have always believed the area you drive in has a huge affect on mpg and my experience has proved that for me.

 

with an 8inch lift, 37inch tires that are 13 wide, unloaded, i calculated i get about 8-9 mpg with my 99 2v 6.8l v10. its a little rough on longer trips, i end up having to stop quite a bit

 

I will say I've never seen 13 mpg and want to know how some on here are getting 15. My 99 F150 5.4 never saw 15 either. Maybe you se the cruise at 54 or something?
