As a gas XD owner, let me comment. 19,000 miles, Pro4X, had the alignment issue, corrected. Had loose clamp on tail pipe, fixed. Had transmission shift issues, new TCM & ECM flash, perfect. That's it.
On the resale value, diesels being better. In say 8 years, with 150,000 miles on both my truck and an identical diesel, will the diesel sell for more? It better. It's 5 grand more to start, my oil changes at dealer, 40 bucks, diesel, 250+, $2,500 difference. Here in FL diesel runs about 20% more than gas, so there's another $1,500 or so. The diesel would cost me another 9 grand to own based on these numbers alone, it **** well better fetch more on a used lot, but 9 grand more? I doubt it.

 

Are the oil change intervals the same in the gas as diesel, are you going 10k between oil changes?

I'm just saying based on your current miles that's only 2 oil changes. So say every 5k on gas or double the oil changes for comparable mileage, diesel oil change is more like $100, gas $60. So oil changes alone are cheaper on the diesel at 15 over 150,000 @ $100 being $1500 total vs $1800 for gas. Now the fuel filter changes will add another $1500 so for a total of $3000, that's about $1200 more over gas and if both owners do their own maintenance the diff probably stays about the same.

Here gas is $2.39 vs diesel at $2.49. Let's say the diesel averages 18mpg over its life and the gas avg is 14mpg. Diesel would use 8,333.33 gals vs 10,714.28 for gas. This equals a fuel cost of $20,749.99 for 150,000 miles at 18mpg costing $2.49, the total for gas is $25,607.13 for 150,000 miles at 14mpg costing $2.39.

So overall I don't see where the diesel cost anyone more to own other then if a major failure happens, but I bet a major failure on a gas model can be pretty expensive today with all the technology in both gas and diesel models.

Now with 150,000 I'm willing to bet the diesel has a value of $10k or more over the gas. New trucks are only going up in price and no one wants to buy a used gas truck with 100,000+ miles to tow with but most are ok doing that with a diesel since they longevity and ease of towing (not screaming in rpms) out performs gas models.

This is just my opinion, I went with diesel because I hope to own it for 15+ years and put 300,000+ miles on it and somethings do cost more for maintenance on a diesel but not that much more. Also diesel avg fuel mileage only increases with miles while gas will see a point where the avg lowers. My GMC 6.0 avg 9mpg in town when I traded it with 143,000, new it was over 10mpg in town. Hwy it was 14.5mpg for its entire life.

 

I get my oil changes done at my dealer, and before the "lifetime coupon" is factored in, the cost is $43 and change, not $60, so there is $86 every 10,000 miles based on 5k intervals. I have yet to see anyone on this forum that has had a $100 DEALER oil change. Most complain of upwards of $300 by the time you add the fuel filters.
You can't factor in a delete as a savings on DEF or DPFs, the delete will cost you more than the lifetime costs of both of those together.
My Pro4X averages 13.8 in town and 16 to 18 on the highway depending on speed and conditions, I would need to turn about 17 and 22 in a diesel just to break even with the added fuel cost here in FL.

 

So what you gas guys are telling me is that 4 more quarts of oil more then doubles an oil change price?

I assume the gas takes 6qts vs 10qts for diesel, fleet guard oil filter cost less then $7. Fuel filters cost less then $90.

Ok so compare diy costs for an oil change, probably $20 diff from gas since oil diff is 4 extra quarts, unless you put the cheapest oil in it and a diesel guy puts the most expensive in.

Do you gas guys change your oil every 3k, 5k, 10k miles? I bet a large number of gas guys have changed their oil 3 times by the time the diesel guy changes his once.

Most guys that own diesels I would think also tend to do most of the maintenance on them. I'm not saying it is cheaper to own a diesel, just that the added expense over gas isn't crazy high.

Should be using a fuel conditioner with every fill up.
Don't Forget the fuel filters @10k
Nissan allows 5k Dino or 7k Synthetic changes for gassers.
While under warranty the safest practice is to have the dealer or shop do the oil changes on either model. Documentation reasons.

 

The Chevy diesel option is 9 grand up front, that's a $2,000 dollar difference between the gas and diesel, while more, not that significant.

I clearly stated DEALER oil changes in my comparison, I am fully capable of doing my own service, but for the $17.99 I pay at my dealer, I'm not getting my hands dirty.

 

Well yeah at that price, but would you say that's a normal everyday price? Heck my wife's Honda CRV costs $60 for an oil change and $45 with a coupon.

Are you getting full synthetic for that price or Dino?

But if you change your oil and I do mine, both with the same oil the cost diff is around $20. Now in 30k you would change your oil probably 5 times or maybe 10 if using Dino to my 3 times.

Again I never said the diesel wasn't more expensive to maintain, it is. I'll have replaced fuel filters, added def and maybe paid more for fuel, oil changes will be even if not a tad cheaper on the diesel. Transfer case, transmission, front rear diff, coolant replacement, u-joints etc etc will all be similar. So in 30k the diesel may cost $300 - $400 more to maintain if we both do our own maintenance and use the same products. At 90k that's around say $900 - $1200 difference.

In 5 years with 90k on both a gas and diesel model which do you think will be worth more money at resale?

Now yes not all will have the same maintenance costs for gas or diesel, such as you with such cheap oil changes but again it's saving you a few hundred over that time not thousands and actually may not save you anything if you decide to change it every 3k.

While fuel costs more for diesel at the pump over 90k miles the overall cost of diesel will probably be the same as the gas, so again not a huge diff there.

My overall maintenance on my GMC with a 6.0 wasn't much cheaper then my 03 Dodge Cummins. I did pay $25 for Dino oil changes every 3k vs $60 diy every 15k in the dodge.

I guess all I'm trying to say is the diesel may cost a little more to maintain over its life but it isn't $4k more. To me it's worth it as I did not like pulling heavy loads with a gas engine screaming.

 

XD gas wins!

Yeah Nissan did the full microphone drop routine on this particular debate.... ????
