I don't understand everyone's belief that a diesel costs more to fuel and maintain than a Hemi. I have an 06 2500 QC with the 5.9L CTD and an 11 1500 RC with a Hemi. I drive 100 miles round-trip to work and for me the diesel is cheaper to use as my daily driver than the Hemi.

The diesel gets 24mpg (Hypertech tuner, Airaid MPX, 4.10 gears, camper shell). At $3.89 per gallon (current local diesel price) it works out to $162 in fuel per 1000 miles driven.

The Hemi gets 17mpg (Stock, 3.55 gears, tonneau cover). At $3.71 per gallon (89 octane at the same station) it works out to $218 per 1000 miles driven.

Maintenance wise, I change the oil in the diesel every 5000 miles myself with Shell Rotella oil - about $45 for oil and filter

So far have changed the Hemi oil once at 2500 miles when I wanted to get it on Mobil 1 (only has 4891 miles on it so far) - about $35 for oil and filter

If I change every 3000 with Mobil 1 in the Hemi, and every 5000 with the Rotella in the diesel, the cost for oil changes is basically a wash.

Granted, the 6.7L diesel with the DPF BS can't make those kind of claims, but in Virgina diesels are exempt from emissions testing so a DPF delete is on option here.

I have 118,900 miles on the diesel and have only replaced the tires and brakes once and have had 2 transmission services performed. Sure the tires cost more for the HD truck, but I got 70,000 miles out of my stockers - my dad is on his 3rd set of Good-for-a-Years on his 05 Hemi QC with similar overall mileage, so again cost is a wash. Sure the brake pads for a 2500 cost more than for a 1500, but I don't have to change the spark plugs every 35,000 miles either like in the Hemi.

The diesel is my daily driver and workhorse hauler...a Hemi is a toy, in fact I get 14 mpg hauling the Hemi around, so it's cheaper to trailer it than driving both to the track!!

Oil changes in the new rigs are closer to every 3000k miles, even the overhead thing says time for a change when it reaches that point. Until I delete and run bypass filters, I will change the oil every 3000 miles to prevent excessive fuel dilution in the oil.

Frequent short trips for a diesel are probably the worst thing you can do to them short of the obvious.. But if youre set on a 2500, get a diesel. In my opinion a HD gasser makes no sense.

Even doing oil changes at 3000 miles, it's only $10 more per oil change for Rotella in the diesel versus Mobil 1 in the Hemi so the fuel savings still more than makes up for it - granted it doesn't require Mobil 1, but I want it.

100% agree for my purposes....the only concession I would make is if someone wanted a mud-buggy with the HD axles and a motor they could rev the snot out of to get wheel speed.

Excellent Point.

Keep in mind you have a 5.9 and it appears to be a 2wd. aka fuel mileage machineee. My 4x4 6.7 non-deleted gets just about the same mileage as my Titan did but diesel is 4.00 a gallon vs gasoline which is 3.65ish around here, so the benefits for me are pretty much non existant. But to the OP if you want to own a diesel for fun... you only live once. Do it.

Yeah, don't buy a diesel and expect to get 24 mpg. I have a 2004, which I think is one of the better years for fuel mileage, and with 4.10 gears, the best I get is 17 mpg. I've heard people claim they get 24 mpg, but I'm sorry, I don't believe it. At least not on a regular basis. At least with my truck, you can't go by the overhead consoles mileage, its off quite a bit, you have to hand calculate it.

So what I am figuring is for 2012 models

2500 Diesel mpg > 2500 HEMI mpg

2500 Diesel mpg ~ 1500 HEMI mpg

For about the first 50,000 miles after I bought the truck (new), I would hand calculate every tank and the overhead display was always within .2-.3 mpg. IMO this is an acceptable variance, because when the pump shuts off, sometimes I squeeze in another $0.75 sometimes it's up to $1.80 because I like to get it to a nice even amount. In fact, when you factor in that variable, it can makes hand calculating inaccurate by .2 to .3 mpg. I used to get about 17 mpg too, then I added the Hypertech programmer and the Airaid and the mpg took off!! They paid for themselves within the first year. In fact, it's been over 25 mpg on a trip back from NJ before. When I got to work today the overhead read 24.2 mpg. I had to drive around the base a little today and it dropped to 23.5 but by the time I got home it read 24.0 again and I haven't reset it in MONTHS. I just set the cruise and go for my commute (Stafford, VA into Washington, DC) and yes, it is a 2WD. I drove all week and still have 1/4 tank left with DTE reading 235 miles - it's all in how you drive.

When comparing 2012 to 2012, I don't believe that the 2012 diesels with the DPFs get similar mileage to the 2012 Hemis...the DPFs are horrible. Yeah, it kinda sucks to buy used, but if considering a diesel, get a 5.9L without the DPF and spend some money on refurb work instead of buying the new garbage if you aren't willing/able to do a DPF delete.

BTW, how can burning raw fuel in the catalytic convertor (this is basically what happens with DPF regeneration) be BETTER for emissions??

Default Diesel VS Gas

Has anyone considered the difference in cost when purchased new, A friend of mine was quoted 6000 more for the diesel. That's a lot of driving over the gas.

That is a good point, I just checked the window sticker on my 2006 (yes, I still have my window sticker )and the diesel option was $5555 and then you have to factor in the cost of a 2500 over a 1500 to be able to even option the diesel.
