Diesel vs gas......................

OK folks, there have been a few to many diesel vs gas threads that have shall we say gone to "Hell and a hand basket"! So if all of you would put in you BEST, no flaming reasons for going gas vs diesel, pro and con, I will either leave your thread, or copy and paste pertinant info to the 4 posts of pro and con of diesel or gas. This can include the GM 8.1 vs Dmax or Ford V-8/10 vs PSD etc too.

Be real and honest in you answers, not hear say, flaming etc PLEASE!

If posts are good ones, I will leave, if inflamatory or trolling in nature, they will be deleted! I will get this stick'd to the top for future parusing for those that need this type of info.

Added 6-23-04

We are getting closer to answers I am looking for etc.



Stuff like Ken's - T-Bone posts are good. There are a few others of you that have not posted, some with a 9 point question and answer type to figure out how you went with one or the other. If you are one of those, PLEASE repost in this thread. I may have to look up whom has done this and PM you, but if you think this is you, you now know what to do.

Also, for those of you with $ per gallon for either fuel right now, I would prefer to see a post with ...."in my area, diesel is typically .10 less than unleaded" then explain your numbers. As currently in the Seattle area, diesel and unleaded are any where from 2.05 -2.30 per gallon, with mid test .10 more and premium about .20 more, with equal high low splits. Two weeks ago those prices were upwards of .30 -.40 per gallon more. people were posting $ per gallon that were for me. "I wish" If someone is reading your post a year from now, they may want to know where your paying 1.65, when the price of fuel is over $3 per gallon. Let's keep prices out of it if possible.

Bert and tin tipi, got into a good discusion on the pros and cons of RPM's, drive train etc. I would prefer to NOT see the quote of the other in responding threads, maybe just write a quick wording of re tranny gearing, instead of the whole 40 words or so in that paragragh, so the repsonse is shorter if possible quicker and easier to read etc.

I have deleted some 15+/- posts, that were off topic etc. Please note, I am trying to keep this at the top, as the ONLY gas/diesel thread in this area. So if one is trying to decide, we do not have to go thru this BS any more. As such, I will be deleting ANY future posts close to resembling this type of topic. I may have to change "this" title to a better one, if one has a better sounding title, to be more positive, better claification, let me know here, or in a PM/e-mail, what ever you feel most comfortible with.

Again thank you for all of you that are keeping responses positive, etc.

Also we could use a few more positive reasons to go gas, as many can see I have both gas and diesel, both have a place! Both have positive reasons to buy that fuel, lets keep the threads etc to that purpose only!

I had an 05 Chev LLY DRW and I got ~15 mpg empty on the highway. I traded it in with 106,000 KM on the clock (<70K miles) and the new buyer discovered that it had 2 blown head gaskets. Nice. I now have a 2010 Dodge MC CTD DRW and get ~10 mpg on the highway.

I did a bit over 23mpg on a 80 mile commute today with my 6.7L F250. I only have 3000 miles on it so it is not even broke in yet. Towing 8000-10000lbs gets me anywhere from 10-14mpg.

The engineers who came up with the idea of dumping raw diesel into the DPF to clean it should be shot... Right after the engineers who came up with the idea of a DPF... And those right after the politicians who changed the emissions standards...

I have owned 5 diesels from 1999-2010. The bad mileage didn't start until the DPF's came into play. Which is why I sold the 2010 and went to the 2007 LBZ Duramax. I get a constant 12mpg hand caluclated pulling my 2011 Keystone Sprinter 323BHS with a dry weight of 8650lbs. My Duramax (6 speed auto) gets 14mpg in town and 19-20hwy. I have a mild tune that does boost the mpg and power up some. 450hp/730tq. I didn't know a 5.4L could pull a 5th;)

Hey! He started it! Now you're telling your fish tale. I've owned six diesels. If I ran slow enough to watch grass grow in the median, I got 12mpg with my diesels. Otherwise I averaged 10.5mpg.
I get 11-14 city, 17~ hwy 70mph and 8.5~towing our mid profile 5th wheel 65mph in sunny mostly flat Florida with my 5.4L F250. Hills, mountains and wind knock it down considerably. Ok, now your turn. :B

I get 23-24 running 62-65 empty with my 8300 pound 11 F350 CC. Towing our fiver (around 11,000 pounds) I get anywhere from 11 to 14 at the same speeds.


That is some great mileage! I only get 20-22 with my 5.4L F250 at those speeds and 10-12mpg towing our 5th wheel 65~mph. :B


BS. A 5.4 2WD F-150 with 3.31 gears struggles to top 20MPG...the only was an F-250 will manage that is downhill in neutral with the engine off!

Maybe off a cliff. I have a 5.4L and have never seen anything close to those numbers. It gets 12mpg (at best) pulling my 4000lb ski boat. My Duramax gets that pulling my 10,000lb TT.
In my opinion, Gas vs Diesel is kind of like Mustang V6 or V8. Both get you to the same place in the same manor, just one is a little more expensive (and more fun) to drive.



Exactly... The best I ever saw was 19mpg in my 5.4L Expedition. And that happened once, from Jacksonville Fl. to Norfolk Va. Towing my 7000lb trailer, it dropped to about 8.

In my experience with a PSD only one i like it was 99 f350 with 7.3L.
670K miles when totaled by SWIFT truck.

We had a 6.0L witch was junk:replaced by ford @37K,99K,175K,280K and when blow up @340 we give up on 6.0L and went to dodge witch we got @440K miles on the original motor and still in service.
Under load 6.0L fuel mileage was ~9mpg,V10 same load 9.7mpg
My 06 V10 was replaced due some idiot stripping the plug thread.(truck was owned by large corporation so they did not care on putting bend new motor in it).I got 334K miles on the chassis now.
If it blows it won't cost me $14K to replace it.

Keep in mine the all the trucks pull 15-19K lbs trailers full time.

I need my trucks to work ,not to sit in the shop like the 6.0 did.time lost while diesel in the shop i take lower MPG and less down time.

In the end V10 vs 6.0 in 5 years of service was cheaper truck to operate.

But if you want to have a big exhaust and turbo wisle go ahead and buy a diesel.

sounds like the 7.3 gave you your moneys worth.We use to have 2 12v cummins in our fleet and 2 24v cummins along with my chevy 454.The 12v cummins definitely got better mpg but they loved to swap trans more than swingers swap wives.They were reliable though and got about 12-14mpg

The 24 v cummins were absolute******we constantly took one truck to drop off while we picked up the repaired truck,cracked blocks,turbos,injector pumps,etc.oh and these junkers only got about 10mpg all with less than 100k problems started at about 25k miles

All in the mean time my 454 never skipped a beat only downside 9mpg.All these dodges were bought cause the Ahole foreman at the time was a diesel only guy and recomended to boss he go diesel to save.To this day my boss says that was the biggest mistake he now has all gas motor 6.0 chevys but i will say some only have 125k and feel like they are on their last leg too but as far repairs they werent familiar with the repair shops like the diesels were.

Roadrescue, That's the reason I chose 30% higher rpm on the uphills and 30% higher fuel consumption. I use my truck for work every day as well as for towing our 5th wheel. My Cummins Rams treated me well but the newer diesels from all three are simply too costly to repair if something goes wrong. And too much to go wrong.

256k on my work truck usually has about 3000 pounds of material in a 12ft flatbed.Gets oil changed every 7500 sometimes 9k.Only needed a trans changed at 158k since front pump went out.Truck still runs solid and good.May burn about a half quart of oil between oil changes.
Hasnt had to have injectors cleaned or changed either!
