i have a 99 b2500 xcab with the 2.5l 4 banger. The truck has 91k on it

my question is this thing is epa rated to do 20 city, 27 highway.

this weekend i did a 630 mile round trip ride on flat interstate, with the back loaded up with a propane bbq grill that was slightly taller than the roof of the cab, a mountain bike, various other camping equip covered with a blanket ac on 2 notches, and 70 mph average speed.

my question is shouldnt i get better than 21 - 22 mpg?

my friend had a 96 xcab ranger with the 2.3l and no ac and fully loaded he got 26 mpg

just was wondering if this is reasonable or if i need a tune up ... this is my first long trip in this truck, and i plan to drive it to wisconsin in 2 weeks, so if i can get more mileage out of it i would like to. I am already planning on running some fuel injector cleaner thru it.

 

sounds about normal...my bro has a 2.5 is is regularly getting around 23.

 

If you want to get better mileage, turn off the AC. I'm not a doctor, I don't know the % parasitic drag coefficient of the AC compressor, but I do know it sucks a lot, especially from a 4 cyl. I never use my AC, it's always windows down,,, but on the other hand, I have my windows down summer, winter, rain or shine.

 

1st i think that mileage was about normal for that load... but do pay attention to your tire pressures. you can go upto the max cold repeat cold pressure that should be labeled on the sidewall. of course running with no a/c and windows up on the highway will help. and slow down!!! 70mph will suck fuel..

 

sounds about right, my grandpa gets around 22 in his all the time. when i drive it about 21. the 2.5l isnt that great of an engine imo

 

I still got 21 when I lifted my ol 2.5L and geared it!.... Where you place your foot is key!

 

Yeah, i get like 23 while mixed driving. However, I normally take 100mile trips, and i notice my gas mileage when i am driving fast. So slow down, i notice a difference between 60 and 70mph. Your stuff in the back plays a role along with the a/c.

I get like 28 nowadays when i drive conservatively on the highway.



I got a Scanguage, and am going on one of theose 100mile trips so i'll let you know how it goes mileage wise.

 

ok cool that its ok and i dont have to spend mad money ... the only reason i was even runnin the ac is i just got my front windows tinted and cant roll em down for a week, and it was over 100 outside

 

I get about 19 to 20 in mine but then again I like to get where I am going....quick and fast. When I had a 3/4 bed full of stuff on the way back from Kentucky, I got like 24-25. Something like that.

 

I get about 23 miles a gallon out of my 2.5l 5-speed. Though the a/c dosen't suck it down as bad as you all say it does, but i do notice a slight loss of power

 

well i have all the pressures at 40 my dad says go up to 45 and i might do better.

also an update on mileage. towed a 5x8 uhaul trailer 300 mi round trip yesterday and got 17 mpg which i figure isnt too bad for doing 65 mph in 4th gear (heard its bad to tow in overdrive)

 

another update on mileage, best to date is 24 mpg doing around 70 with the ac off and bed fully loaded

 

Okay, i totally forgot. On mytrip. I was getting an average of what i'd say 26mpg read off the Scangauge. I was doing 75ish+ the whole way with nothing in bed. I could tell it'd read higher when i was traveling 60mph and less. So i should drive slower to save gas....oh well...

 

i agree fully, i have started being a little easier on the right foot, and bought a scangauge, and i am getting around 29MPG now

 

I got 14 mpg on my last tank. Something's not right.

 

WRONG!

do not take this guys advice, you should NEVER run the max psi on the sidewall.

go by what the door sticker says.

anything above 35psi is retarded imo.

 

true according to my scanguage when im idling i use like .69 Gallons Per Hours but when i turn it off i use .39 GPH

thats with the "Max A/C Setting fan speed 4"

 

update ... im getting 25 with just my mtn bike in the bed ... and thats on this ****ty 10% ethanol wisconsin gas.

Plan on going to milwaukee next week without the bike (500 mi round trip) ... ill see how it does then

 

24 with the bed empty going to milwaukee.

oh well i guess thats how it goes.

 

mine gets around 22-23

 

whats up fellow wisconsian ... havent made it down to GB yet ... moved here at the end of may for the summer from CA.
