Default 2500: 2012 vs. 2013

I'm curious which is better for the 2500...2012 or 2013? From my understanding the emissions system on the 2013 has changed and now requires diesel exhaust fluid (i.e. pee). A lot of folks seem to be deleting/modding their 2012s and below to improve emissions.

Would a stock 2013 emission system be better and not need to be modded, or is the new emission system just as annoying?

Excuse my question. I'm not a diesel person.

This is just my opinion. The answer depends on the big picture of how the truck will be used. If the truck is gonna be left stock, as far as emissions, the 2013 is a better choice. The DEF system on the 2013's will work slightly better and give slightly better MPG's than the older system. If you are gonna delete the emissions, the 2012 is a better choice. But here's the problem. The EPA cracked down in November of 2012 on the performance tuner manufacturers and they are no longer producing "offroad" or "race" tuners that will delete emissions equipment. There are still a few older tuners sitting on shelves here and there but they are becoming more rare everyday.

Both emissions systems suck for sure. But I just bought a '12. Couldn't pass up the huge savings, and I'm not all that impressed with some of the changes for 13's

Thanks for the info. What kind of gains were the 2012 models getting with the tuners and emission deletes?

I've heard that the 6.7 Cummins is probably one of the best, if not the best, diesel engines out there right now. It's a shame they had to muck it up with all the emissions stuff.

It depends on how you drive/use it. I recently made a trip from south Ga to Atlanta. I averaged 17 MPG. Personally, I think that is amazing considering the truck is lifted, running 37 inch tires and I spent most of the time driving 65 mph to 80 mph. Normally, I average close to 16 mpg (combined city/hwy).

It all depends on what you want. Both are fantastic trucks

IMO. I'd go 12 because it doesn't require def fluid.

Now if I was looking at laramies or loaded slts, then 13 for the new screen.

You won't be disappointed with either truck, both will hold value, and both will get the job done

Wandell,

16 is awesome with the lift and huge tires. I get 17 (combined city/hwy) with the Hemi, and my truck is completely stock.

Diesels will hardly be affected by lift wheels and tires. They are built to tow heavy weight and still be efficient. Adding tires is like adding weight to a trailer. The only thing really effecting the mpg is the wind resistance. We had a 06 2500 Mega Cab 5.9 that averaged 19-20 hwy and after 8" of lift and 37" toyos on 20x12 Fuels it averaged 17-18 hwy. Granted it was a 5.9 but most diesels arent affected as much as a hemi is by lift/wheels/tires

That's good to hear. I'm getting my lift on soon, and although I don't really care what mpg I get, the more the better. Less in the fuel tank = more on mods

You are right about wind resistance. We took a 2 1/2 drive to the beach last week. Traffic wasn't bad, but with the curvy two lane state roads there was no passing. Traffic was also slower than usual. So I just chilled and backed down the cruise control. I was only able to drive 45 to 55 mph most of the way. The result? 20 mpg!!
