That's what the little lights said. (it was on a long downhill run with a trailer pushing me) Just how accurate are those little overhead indicators on the Dodges?

I saw as high as 99 mpg on our '98 Park Avenue when going down long hills and that was as high as the display could go. Just think of the average you could get if all your driving was long downhill runs being pushed by a trailer! <g> By the way, how low did the mpg get on the long uphill run towing the trailer?

(it was on a long downhill run with >> a trailer pushing me) [quoted text clipped - 11 lines] > > Ron Didn't really have any LONG uphill runs, but on those where it was somewhat, we got around 12 to 12.5 by the lights. A check over 365 miles put us at 13.64 mpg overall. The truck has 15k on it, it has been said that you can't really tell what the mileage will be until you have 30k. So, we'll just keep an eye on it. Right now, it's too much mixed city and highway miles to get a good read on it. Steve >>> That's what the little lights said.

I have noticed a difference between winter and summer diesel also, with summer diesel getting better mileage. My '06 averaged 19.05 mpg for 6,000+ solo miles in MT last summer, but only 16.16 mpg for 5,000+ solo miles in south TX this past winter. MT ends up being almost all rural driving while the south TX is mostly urban driving. Of course there is no up and down in south TX like there is in MT. <g> Ron > On both my '01 and '06 Chevy 3500 Duramax the mileage kept creeping up > until I had over 25,000 miles on them.

Most was two lane highways with speedlimits of 45-70 at elevations of 4,900'-11,000'. Most of my south TX driving was on urban expressways with 55-60 mph speedlimits and city streets.

I really couldn't tell you what a 55-65 average over say a thousand mile trip would be, because I haven't done it yet. I might get a chance to do some of that speed driving once we get moved, and get a fifth wheel. For now, it's faster Interstate speeds. A friend of mine said he took one of the older ones ( like a 97) on a trip to Alaska with a fiver and got 15.5 for the whole trip. I'm SURE that was a lot slower.

Well, those of us who don't know everything sure apologize for the pain we cause those of you who do. Steve > Well, those of us who don't know everything sure apologize > for the pain we cause those of you who do. Aw, shucks. I didn't mean nuttin' by it. :) You'll notice that even *I* do make mistakes (EXTREMELY rare <bg>), demonstrated publicly with my "double sig" on my previous article. I can't even run my own newsreader. <sigh> Signature:) JR >> Well, those of us who don't know everything sure apologize >> for the pain we cause those of you who do.

Steve >> And it was a small 5er or he drove a lot of solo miles. >> [quoted text clipped - 4 lines] > > Steve "Will", you actually read what he post! It was a comment I fthought was fairly obvious and bacause of tthat ,in retrospesct, I propably should have said anything. Ron With 5000 miles on my '06 3500 Dodge I got 21mpg one time from Tucson to Phoenix, going about 60-65 without A/C. It is downhill. Now with 9500 miles on the engine, I get 17 mpg at 75-80 mph with A/C. Without A/C I get over 18, same speeds. > That's what the little lights said. (it was on a long downhill run > with a trailer pushing me) > > Just how accurate are those little overhead indicators on the Dodges? > > Steve Pitifully bad mileage in my opinion. I put over 10,000 miles on my Cervelo last year and didn't burn a single drop of gasoline or diesel. I guess I could count water instead. I can get about fifty miles on a quart of water. That makes 200 miles a gallon. Try beating that you air-polluting, huge carbon footprint, global warming hastening, fat, out-of-shape couch potato. For recreation you pollute the air and cause the world to get hot and melt the poles. Disgusting.

That's what I was saying. Both of those numbers are fairly useless except as a Gee Whiz item -- MIGHT be "accurate" but still meaningless. If ya shut down completely and coasted, the indicator(s) would register as close as they're programmed to infinity. So? We've had mileage computers in several vehicles, and have always found them extremely accurate when displaying trip or average mileage. The instantaneous indication is mainly for amusement. Sorry if you were just looking for an argument. Will Sill GILLETTE'S PRINCIPLE: "If you want to make people angry, lie. If you want to make them absolutely livid with rage, tell the truth." >I see where "Steve B" <ExSurDO2Diver@Neptune.com> contributed: > [quoted text clipped - 25 lines] > GILLETTE'S PRINCIPLE: "If you want to make people angry, lie. If you > want to make them absolutely livid with rage, tell the truth." Sorry you misconstrued the comment on 43.3 mpg instant temporary measurement as a claim to good mileage, as would be gained by using gas magnets and/or louvered tailgates. You DID notice that I said I was on a long downhill run with a loaded trailer hooked on. Didn't you? I'm sorry that you missed the sentence that contained the meat of the message, and that was an invitation of comments and opinions on just how accurate the mileage indicators were. I had one in a car once, and it seemed to be hooked directly to a vacuum line. It was just a turning pointed thing, not digital numbers. When you hit the gas pedal, it would decrease the number. When you let off the gas, the pointer would go to a higher number. As stupid as I am, I figured out pretty fast that its effectiveness as a mileage indicator was suspect. I wasn't looking for an argument. Just sensible lucid answers from people's hands on experience. Sorry you were not able to provide same. Steve I see where "Steve B" <ExSurDO2Diver@Neptune.com> contributed: >I wasn't looking for an argument. Just sensible lucid answers from people's >hands on experience. Sorry you were not able to provide same. Off yer meds, Steve? Sorry I assumed you were genuinely interested in why you were getting high numbers while coasting. I won't make that mistake again. Virtually all of these on-board computers that provide a mileage number do so by mathematically comparing fuel flow with speed data. They are very precise but will not give a useful instantaneous number when parked idling or while coasting. Will Sill The Curmudgeon of Sill Hill >I see where "Steve B" <ExSurDO2Diver@Neptune.com> contributed: > [quoted text clipped - 13 lines] > Will Sill > The Curmudgeon of Sill Hill f.ck off, Will. Reread the thread. You're the one who couldn't answer a simple question. One paragraph, you make insults, and in the next, just go right into a lecture stance. You're a piece of work. A piece of sh.t. Plonk.

Hehehehe! I just LOVE it when a "connection" is made with someone with obviously THIN skin. :) > Reread the thread. Admittedly, you inquired about Dodges. However, I suspect that Will's reference to Volvo was no further departed from Dodge than the comments of others. ...and it was no more irrelevant than "43.3 mpg on Dodge 2500 Cummins". > One paragraph, you make insults You made the first insult. > You're a piece of work.

You both need to go back and reread and follow the conversation a little better. Steve I see where Jim Redelfs <jim.redelfs@NOSPAMredelfs.com> contributed: >Hehehehe!

I promise not to lay awake agonizing over his momentary loss of sanity. Will Sill The Curmudgeon of Sill Hill > Steve is sometimes a sensible guy So I thought. > sometimes a nut case. I'm still not convinced. Still, I don't see any point in coming out swinging. > I promise not to lay awake agonizing I dunno... It sounds like Captain Morgan and Coke time: Two of my three daughters are here and EVERY one of my four (and-a-half) grandchildren are being put to bed as I type. Life could be worse. Signature:) JR > You're over the hill, Will. > > Steve ---------------------------------------------------------------------------------- Absolutely has nothing to do with RVs, but that comment reminded my of the James Taylor song with the line something like: "I don't know when I got to the top of the hill, but I intend to enjoy the ride down the other side". Rock on James Taylor (and Will Sill). <grin> Mark |
