Hello all I'm new to the site and new to diesel's in general. I am looking at getting a truck for my side business but also I do commute 50 miles a day. I don't need a tow rig just want the higest MPG diesel made which I think is the 1994-1998 12V cummins right?

I dont need a extended cab, or long box just a reg cab reg box my only requirement is 4WD.

When I started my search there are a few options available but they all have 150,000 to 230,000 miles on them. What do you look for at this miliage?

Also the manual is a better trans correct? I would like a auto for the wife to drive everyonce in a while but not required.

Any mods to the 12V to get 25 mpg highway? New gears, exhaust, etc.

Thanks a lot I hope to learn lots on here. I'm a mechanic nut with almost every toy and usually power hungry (100hp nitrous shot on snowmobile, 220 hp jet boat, Subaru STI stage 2 380hp 400 TQ, etc) but this is the first time looking for mileage! Thanks!

First at 230,000 the engine just started to break in, don't worry about mielage on these engines they run forever.
Manual will last longer, the autos aren't all that bad in my opinion there are worst. 2wd will give you better mpg.
Striaght pipe exhaust, highflow air filer(k&n). 3.5 rear, narrow 30" tires. after market intercooler, aftermarket intake, etc.

Keeping your foot out of it will improve your mileage over anything else.

How do the trucks hold up to that mileage, pretty good or what would you look for there? Wheel bearings, ball joints, etc etc. Thanks!

with 150k i would hope to get a 98, but i would pay around 10 g's for a 96-97 standard cab long bed 4wd 5-speed manual. a buddy of mine has a 96 2500 std cab long box 4wd, a few mods and is getting between 18-22 mpg depending on the right foot and where you are driving, the best 12v is 96-98.

My 1995 gets 27-28mpg easy. The 12v's are the easiest on fuel, my 1999 24v gets around 24-25mpg as well.

That is a loaded question it all depeon gears and how it is equipped and what you are carrying in another words to mant variables for a straight answer but on average I have heard roughly 15 to 20 miles per gallon :thumbsup:thumbsup:thumbsup:thumbsup:thumbsup:$::$::$:

I think you can realistically get 18-24 mpg in a 12 valve depending how you drive it. some guys claim near 30 mpg, but I call:BS: the 1st gen 12 valves had a pretty high ratio option 3.08's. those together with a 5 speed might get you real close to 30 with a light foot. as far as I know the P-pumped 2nd gen trucks had 3.54's or 4.10's. I dont think they came 4wd, shortbed and manual. 5 speed equals longbed and the heavy duty dana 80 rear. im not biased or anything but if I were you I would look for the truck in my sig, or better yet the rare as hens teeth `98 quad cab(4 door) 12 valve. good luck :thumbsup freinds dont let freinds drive duralacks or powerhoax

dont get a k n' n air filter or really any oiled filter cause teh turbo will suck the oil right out of the filter espesially when it has been re oiled and cleaned. and that oil will ruin your turbo. havent had one happen to me but im not going to chance it and have to have a new turbo put on her.

regarding price, i found a bunch of 4x4 manual trans diesel trucks for under 10k, all with less than 230k miles on autotrader.com.
that's where i got mine, paid $9800 for it.

Mine gets about 20mpg both in town and highway on summer fuel.

When i was driving it home i definately knew when i got a tank of winter fuel, this thing hates it. my milage dropped to about 12-15 doing the same speed on winter fuel!

Not sure what the deal was there, it was getting the same brutal fuel economy in town for a while but its starting to get better even though its still running winter fuel...
