the "6.7 emissions delete $$ savings"

ive been learnin a lil about the 6.7 emissions deletes. . .of course there are tons of threads where some poor soul has to make the choice to perhaps void his 100k warranty and do the deletes, or leave it alone and live with himself knowing he's shooting diesel down his exhaust pipe. not to mention retaining the emissions is like allowing your kid to smoke cig's at an early age hopin he doesnt get lung cancer, but hes got health insurance til he's 35 so you live with it.

anyways. . .i think it would be helpful for many to see some real world numbers of the long term savings from the deletes. ive browsed a buncha threads of this nature and havnt seen any math, so im sorry if its been said over and over but here it goes. . .these numbers are based on the hope that diesel doesn't average more than $3.00 over the course of the first 100k of truck life, also assuming every1 has the 100k engine warranty that they are in fear of voiding.

100k miles @ 12mpg = $25k
100k " @ 15mpg = $20k
100k " @ 18mpg = $17k
100k " @ 20mpg = $15k

any1 who is conscious of their oil "health" is gonna change their oil more frequently with emissions equipped vs deleted. . .

100k miles @ $100.00 a change every 3,000 miles = $3,300 (emiss equipped)
100k miles @ $100.00 a change every 6,000 miles = $1,600 (deleted)

so, depending on your mileage setup you will save anywhere from 3k-10k in fuel alone ($3/gal avg.), almost 2k in oil changes, and "get your kid off the cig's" peace of mind. as a man who loves his truck, and loves his rippin, the numbers tell me to do the deletes, bury the junk in a box in the backyard with hopes never to dig it up again. . .but itll be there if ya need it.

if its cheap it's not easy, if its easy it's not cheap

My numbers would be more optimistic.Oil change every 10,000 even though the oil analysis is still good. fuel mileage is 19 city 23 hwy.Did deletes soon after I drove it off the lot (500miles).

Good info.

To take that math a bit further...
The savings of about $5000 of fuel over an expected 7 years (15000mi/yr) is about $714/year of fuel savings.
Less Oil changes would result in about $300/yr savings.
So about $1000 overall savings/year to have deletes.
That doesn't take into account the times saved due to downtime for dealer repairs of the emission equipment.

yea i figured it would be helpful for a lotta folk who are on the fence about the deletes. the savings alone would pay for most/all of a motor replacement in the highly unlikely event that it breaks in 100k w/o a warranty. at least youll KNOW your motor wont fail from an emissions related issue, which is the primary failure factor among these trucks. math doesnt lie, and its nice to see it.

Good information here and making it a sticky would be nice too. I wouldn't put it in the 6.7 tech section since most newbie's are less likely to look there. Making it a sticky in the 6.7 performance section would provide much more exposure.

MINE 2007.5 dually somewhat stock
HERS 2001 2WD 2500 auto... it has a grid heater delete

I had 10 CEL's on my 08 in the first 50k miles and was in the dealer for those 5+ times. That was 5 days minimum w/o my truck with a few of those being out of town road trips causing numerous delays. All the CEL's were EGR/Emission related. That for me was the deciding factor. I've had ZERO delays due to emission equipment since my change.

Another thing to calculate is the cost of a DPF which if what I'm seeing is correct isn't going to last you much more than 125-150k miles. What is that $2000 bucks from the dealer? And what is a turbo from the dealer and the diminished use due to the EGR?

Looking at it another way... Let's see if I have this right.
12mpg at $3/gal is 25 cents/mile.
20mpg at $3/gal is 15 cents/mile.
So, going all out with deletes, plus some other performance products would run me about $2800 the way I have it figured(BlkMaxx & Mount, FloPro turboback, S&B intake, BOD horn, GH delete, EGR Cooler Delete, H&S boost tube).
***Theoretically*** I could recoup that $2800 in about 28k miles if I was to keep my foot off the onion.

This would be good for my CFO(better half) to learn.

You guys think 20 mpg is realistic for what I have listed above? I know 12 sounds pretty damn spot on for me now.

Excellent thread. I know there are alot of variables(driving style, hwy vs. city, loaded/unloaded, etc.) but this thread still opens my eyes. Thanks to the OP.

I was just figuring that out the other day but got sidetracked when I saw something shiny
To take it a step further, we all know that fuel is only gonna get more expensive so the true savings has yet to be determined.
Thanks to side2000 and and others for posting hard numbers that really put this into perspective
I agree this should be a sticky in the 6.7 performance section

The next cost savings I'm considering is changing my front axle to floating hubs. Essentially making my truck 2x while on the highway. With a savings of 2mpg I estimate it would take 7 years to pay for that mod. Not quite sure that one is worth it.
It will look much more appealling if diesel gets over $4/gallon again.
