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!

Bert,

Actually, the HP and torque numbers that have been bantered around for the v6 "baby" Duramax are about the same as the original 6.6L v8 Duramax (300HP, 520TQ). That type of power is easy enough to get out of a smaller turbo-charged diesel with the proper set up.

Comparing a 5l diesel to the 8.1l is not really a fair comparison. If the current trends prevail, the 5l will produce no where near the power of the 8.1l. I suspect that it would produce somewhere around 250 HP or less compared to the 8.1's 330 or 340 HP. It would enjoy better efficiency, though.

someone in another post claims of hearing Chevy producing a 5L diesel engine for the 2006 or 07 model Tahoe/Suburban/Silverado. If my Calculations are right, that would put the torque rating in the mid 400s, about equal to a BB 8.1L with much better effiency. This is only here say, but a step in the right direction for someone wanting the best of both worlds...reasonable power and efficiency.

Some of that how long the vehicle last depends on the owners ability to keep a vehicle maintained. I have a 92 Chevy C1500 with 228k on it. I just have an issue with the premium that the dealers are asking for even a 3/4 ton truck anymore. It's insane.

scrity,

I would like to see some small 4 or 6 cylinder diesels in 1/2 tons with 5 or 6 speed manual transmissions.
This would be a better combo than we have with the small V8`s with more power and much better fuel efficiency.Just think of getting 25+ mpg MT and maybe 18 mpg pulling a 4000- 5000# trailer.This could greatly compensate for the present desparity in fuel prices.
I could live with that!Maybe help out with our foreign oil dependency also.

Best Regards,

To re-ignite this topic in a slightly different direction, and it has been mentiomed before, Diesels are omnivors in that they can consume veggie fuel as well as dead dino. They are also much more fuel efficient than the equivelent gas powerd engines. It could be argued that Diesel owners are more patriotic ๐Ÿ™‚ by helping to save the countries oil import bill and also, down the road, helping to create a situation where it will be feasable to grow our own fuel.

JIMNLIN,

Diesel here has not been cheaper than regular. At best it hovers right about at the same cost and as I noted, this winter went to $.40 greater at a number of stations.

You might expect to see more diesels at a truck stop wouldn't you? Don't diesel owners sometimes like to get their diesel there feeling it may be fresher?

I agree that in some parts of the country a gas rig is less in demand but around here I see plenty of 8.1s and 6.0s. I believe GM sells quite a lot more of the gas rigs nationally than the DMax but then too the demand for the DMax I think outstrips the supply. But even if GM were able to supply enough it remains to be seen if that situation would change.

But whatever. I think a lot of people want diesels today simply because they have become popular and might I add, a lot of guys feel the vitamin T swell in them when they think of a big bad turbo diesel..say it ain't so? I see big bad t-diesels all day long that no sooner see much hauling or towing than a compact does. That tells me something.

All I'm saying is that I have a resonably large and heavy trailer and my gas rig handles it very easily. The 8.1 engine is built tough for the very reason that 20% of output is aimed for the marine market. Check it out, you can read about the 8.1 in many marine sites in various states of tune. It's BIG engine and in standard truck form it's pretty mildly tuned. But I do get better mileage than older BBs and even some of the smaller gas engines when towing.

I don't care if people buy diesels, that's a personal issue. But again, the whole diesel thing really gets way out of whack on this forum.

Diesel fuel in NE Ohio is $.50 to $.60/gal more than 87 octane gasoline.I feel I`m getting the mileage that most folks get with 3/4 and 1 ton diesels.Of coarse most folks with diesels pull heavier and bigger loads than I do.
Even tho I would love to have a diesel[maybe just to have a Man`s truck!Ha!]with my setup and the desparity in fuel prices, I can`t really justify it.
If and when I go to a heavier and bigger TT, I will looking towards a diesel, but,even so,I would like to see fuel prices more in line with gasoline.

Mannlicher,

I am in the same boat as you. Since I tow a 26' TT only about 10% of the time that we actually use the TV (5.3L Suburban) it does not make much sense to trade up UNLESS we get a larger TT. At this point, I am pushing the tow limits with a fully dressed out trailer and we definetly crawl up the steep hills, but for 10% of the time I do this I can live with that.

Is a Diesel in the cards if we get a larger TT? YES. I too am unhappy with the gas/diesel price difference right now but would like to think it's a temproary aberation and the two prices will likely be similar in the near future. When we do go diesel, my feeling is to either buy one that's two years old with around 20k miles or wait for another round of incentives from the big 3. Chevy had a week 2004 sales year and the street thinks some engine and body changes may be in the cards for next year, so they could start giving some new trucks away soon. Cold be wishfull thinking but we will see.

Good luck
Dale

diesel has been cheaper than gas for 40 years ,its only been the last several months that you can use that excuse. I burn 50 percent less fuel than you . Saves on our countrys fuel supply.
Sure I traded a small block gasser,most folks did, for a diesel, and it don't make sense to trade up to a BB thats burns more fuel than my SB did. Makes more sense to get the power and better fuel milage from a diesel.
Sure the diesel option is higher because its a superior engine. I paid less for my Dodge/Cummins than , after rebates, GM was asking for the 8.1 rigged like yours. The 8.1 doesn't have a fleet average anywhere near the Cummins for a reliability factor. All the hotshoters I see at truck stops that drive GMs are DMAX not 8.1's.
Resale around here is very low for BB gassers and used diesels don't set very long on the lots. I have a buddy that has a used car/truck lot and handles Ford/GM pickups and SUVs. He's not taking any more BB gassers on trade. He has to many setting on the lot that he can't get rid of.
Trading old diesels for newer diesels. You bet. You get a quieter more reliabe, better fuel milage and lower maintance costs than the older engines. Recoup the extra cost?? Sure the diesel holds better sell/trade in than a BB and used a lot less fuel than a gasser.
Diesels make more sense for towing big loads than a BB gassers as far as reliability, fuel consumption especially the Cummins which BB gas can't compete.........JIM

Sack1, thanks for such well stated comments. As a recent convert from class C to 5er owner, its refreshing to see a bit of reality in the information posted here.
One last thought, and then I'll shut up. I've seen so many post from the diesel crowd on how they can pull almost any mountain at 60+ mph. Well, isn't part of the joy of RVing slowing down a bit and enjoying the beauty of nature???

Does all this mean there's no reason to buy a diesel? Not at all. But let's not make more out of it than exists.

Thank you and goodnight.



Sounds a bit like some good old fashion diesel envy...

I want to (again) point out that which seems to be glossed over by diesel fans.

Depending on where you live diesel isn't always cheaper (here) than regular and this winter here it has been $.40 higher, almost taking away any cost savings through extra mileage.

Comparing an older V8 (gasser) to a new turbo diesel and then proudly stating there's no comparison. Since when would anyone go shopping between an older truck/engine with a new one? It may be a comparison for the person trading up but anyone shopping new out there has the new BB gas engines as well as the diesels to compare. They are rated more closely on towing ability.

Recent gas engines are more fuel efficient than the older ones. Time hasn't stopped on the gas side of things either. In fact, GM is said to be looking at a line of V10s for a broad range of vehicles, including their trucks. If diesels were the only way to go why would they spend millions to do so? (Ford and Dodge boys can keep your comments to yourselves)

The initial extra cost of a diesel is substantial. Why does that seem to be ignored while proudly proclaiming that mileage is better?

On the subject of resale value it matters on how much percentage retained of the original cost. Not just that a diesel will have a higher resale value. Take a look at any vehicle valuation guide and you'll see that they both retain a similar percentage of the original cost down the road. Maybe not the exact same percentage but nothing shocking that I've seen. Just as a more expensive Cadillac will cost more initially than a Chev it will most likely be worth more at trade-in.

On the issue of engine longevity, GM for example, rates both the 8.1 gas engine and Duramax as 200K engines. That sounds about the same to me. Just because an engine is diesel does not mean you're going to see 300k miles roll around. When's the last time you had a vehicle that long? Would you likely want to be towing that nice new trailer with a 15 or 20 year old diesel? 300,000 miles is 15k each and every year for 20 years. Yes, some people rack up considerable miles but do you? Would you?

If you trade your diesel to supposedly take advantage of superior trade-in value wouldn't you likely be forfeiting that longevity point?
Look anywhere on this forum. Some people touting the longevity issue have had several diesels over a relatively short period of time. Again. look at the number of PSD 7.3 owners who decided to buy a 6.0 or the Dodge owners who just had to have an H.O. Cummins when their only a few years old truck was still serviceable. Did they recoup the diesel's extra cost with fuel savings or take advantage of extra engine longevity?

Remember too, even with a fairly heavy trailer full throttle is rarely needed to get down the road. Full throttle is the only time any engine will produce maximum power (at any given rpm). Too many people like to bench race and state factory torque and HP figures. That's great but that's not what gets to the ground. I have plenty of power. I barely have my foot in it running down the open road. The engine just purrs along, quiet and smooth. I can get about 9.5 mpg average for a tank while towing. I know that diesels return only a few mpg more for the same trip with similar weight/style of trailer. I do not get 6 or 7 mpg like some insist I must because for no other reason than that I have a "gasser". You can expect a diesel to return from 20 to 40% greater fuel mileage than a comparable gas engine. That's all well and good but proudly stating that one gets 15 mpg in town somehow pales when many sensible cars can return twice that mileage. Do you fire up your big heavy-duty truck just to pick up some washers and light bulbs at the hardware store? That's a waste of fuel no matter what's under the hood.

Does all this mean there's no reason to buy a diesel? Not at all. But let's not make more out of it than exists.

Thank you and goodnight.

I sure like my diesel... It is our first and we will continue with a diesel far into the future. Towing we are getting 16-17mpg at 62mph (hand calc'd).

Hi folks,
This is my first post so you`ll have to bear with me thru the learning process.
I have been reading this forum for a year or so and I have gleaned some very good information.
First of all, let me say that I would love to have a diesel.If I towed big heavy loads I would have one, probably used.[My German-Irish ancestry finds it hard to justify $40K for a tow vehicle.]
I drive a 2000 Dakota,4.7 V8,5sp,3.92 LSD.I sized my trailer[~97 Flagstaff 25FK]to my truck,thanks to you folks on this forum.I get 18-19mpg around town[mostly freeway]and 18-22mpg on trips.I get 12.5mpg towing my [4000# loaded] trailer.
Diesel fuel in NE Ohio is $.50 to $.60/gal more than 87 octane gasoline.I feel I`m getting the mileage that most folks get with 3/4 and 1 ton diesels.Of coarse most folks with diesels pull heavier and bigger loads than I do.
Even tho I would love to have a diesel[maybe just to have a Man`s truck!Ha!]with my setup and the desparity in fuel prices, I can`t really justify it.
If and when I go to a heavier and bigger TT, I will looking towards a diesel, but,even so,I would like to see fuel prices more in line with gasoline.
Thanks for listening.

14mpg while pulling the 5er or just driving to work. I have towed with a gas v-8 and a diesel 7.8. The diesel has a lot more power to tow a heavy loaded 5er. Most of the time, unless you look back through the center mirror, you don't even notice the 5er back there. Having towed with both gas and diesel, I would always choose a diesel again. Also, look at the number of 18 wheelers that are gas compaired with the number that are diesel. There must be a reason you do not see gas powered 18 wheelers on the road. Happy trails...
