Because back in 2000 they didn't care as much about MPGs as they do now.

 

back then all the pickups got crappy milage. my inlaws ranger only gets 13-15mpg. compared to a full size, us dak guys get better than them too, and faster! lol

 

My 98 5.2 got 10 on a bad day and 15 on a good day

 

Yea even my small 2.5 is not very good on the MPG scale trucks were not made for MPG back then even though you would of thought the new at that time 4.7 would of had better MPG.

About 1995 to 2006 they were on the bigger and bigger car/truck mania in America MPG was not looked at it was POWER that people wanted gas was cheap back then.

 

You got a couple of options. A deal with the mpg, B. Ditch the truck for a car Or C. Buy a diesel lol I opted for option C lol

 

We really like the truck, so I guess I'll have to deal with it. lol
I understand what you're saying about the need of mpg back then, but you would think it should have better than this. Especially a 2-wheel drive, EFI, over drive tranny 60 mph @ 2,000 rpm and small tires.

 

A 4.7 2wd 60mph on the highway should be able to at least get 16. When my tranny went in my truck I was driving a 4.7 grand cherokee and around town I got 15-16 and highway was 19mpg. That was me being kinda hard on it lol.

 

2000 rpm @ 60mph. what rear end do you have in there? im at 1550 @60. that could be your mpg issue. towing my camper with the o/d off doing 70mph im at 2500rpm and still get 13-14 mpg. weird.

 

Prob different gears. Im the same way in my ram 60 at 2k but I have 4.10's

 

That is weird !

With some searching, it's either a 3.55 or 3.92. The truck was ordered by the original owner (I'm the 2nd) with the tow package, so do you think it's the 3.92 ?

With no manual, where else would the information be ?
In the vin tag ?
Maybe a tag on the pumpkin ?
