Diesel Fuel economy

Postby waterfowlhunter » Sun Feb 22, 2009 7:02 am

I will be buying a New (or used to get away from the DPF crap) Truck this year. I am looking at the Dodge and GM diesels and wondering what fuel economy your getting with STOCK trucks. My Neighbor and his son both have silverados and both are claiming 21mpg + but only after they got about 5000 miles on the trucks. they were getting around 12 at first. The prices are WAY down on trucks right now and it looks like it is time to buy.

Thanks

My friends 03 2500HD gets about 21 highway, which I think is pretty average amongst all the diesels it seems. Good call on staying away from the DPF equipped trucks.

Your not gonna get one without DPF unless you go back to 07 models, or do a DPF delete. The dodge guys have bout got it all worked out and getting great gains with it gone. I get around 18-20 in my 5.9. :thumbsup:
If they're dumb enough to be lured in by plastic you're really just doing them a favor.

Right about the DPFs on all accounts. I have heard of some tremendous gains with a DPF + programmer, even more if you add an intake and exhaust.

If you take a DPF off make sure you put it back on before taking it to the dealer if its warranty
get a 08 power stroke than buy a turner called spartan {250} than you can turn on and off any program you want
mpg 12-24 depends on how you drive and pulling

Theres guys on cumminsforum with a dpf and egr delete talking 24 hand calced, thats pretty good for a 7000# ride. I just got back from arkieville and the overhead said 21.5 which is propably more like 19 and a half. I can live with that especially with diesel at 1.75 right now. :thumbsup:

Neither I nor any of my friends have stock trucks, but we've got a couple of them well over 600 rwhp and getting 24 on the freeway, expect about 19 on a stock GM

Actually it depends on the dealer/service dept. And yes, Spartan is the cat's meow to these trucks. Now they have a 275 tune out.

Your going to get all kinds of different answers and its all based on peoples different driveing styles, where they live, city, hwy, speed, etc etc. I don't think your going to see a jump at 5k, you will at around 40k but 5k seems a bit soon. If you want answers but don't want to be overwhelmed by a big forum site PM me and i'll tell you a good site with good people. OH just for crap&grins, I get 14 in the winter and 23ish but its not stock and I havn't driven it in the summer yet with all the new mods yet either. Plus my MPG's are low because I can't keep my foot off the skinny pedal for hearing that sweet turbo whistle.

It will probably end up being a GM as I get the employee discount and my dad gets extra discount vouchers all the time. I can get a supplier discount on a dodge but not sure if they will still be around in the comming years.

I read that International will purchase the Jeep brand and GM is trying to buy chrysler but does not want the dodge division. I also read that international is going to bring the scout back out and supply MB diesels in the entire jeep line.

It will all depend on if I can find a used one with VERY low miles at the right price. if Not I will just buy new and deal with the DPF. My plan is to be burning Cooking oil in it after the warranty is up.

:hijacked: Not to sidetrack here, but the International/Jeep thing is just a rumor. I've heard and read that a couple places but found it isn't true.

If any of the big three go down we all go down, so buy what you want there not going anywhere.
