You are there! Five percent of 20 is 1, an increase of 2 mpg on 20 mpg is 10 %.

hey, guys: quit belly achin' about the speedometers being off. i'm from the old school where all speedometers were off; this is pretty typical, and it doesn't bother me in the least. my gps shows about 56+ mph when the speedo shows 60.
 
as for mpg, i'm getting around 24-28 in my sprinter 2500 118" wheelbase regular roof line. but i drive with fuel economy in mind. those of you who are watching your mpgs carefully, consider your speed and load (obviously) but also your roof profile. i'm still pretty happy with my sprinter and will have it for a long time (i sure hope so, anyway). the better mileage (compared to the usual gas engines available with the domestics) and better inside dimensions will convince me i made a good decision for a long time.
 
i'm also seeing more mobil 1 0w-40 on the shelves in the local auto stores and at wal mart.

a lot of mfgrs are now making their speedos read fast intentionally
VW does it but you can punch the right code into your climate control unit and it will display the accurate speed digitally
 
reason for the fast reading speedo is litigation concerns
go figure - that was from the vw na technical director

MPG ratings are averages.
 
With economy in mind, a given vehicle, with the same driver will not deliver the same mileage when driven under different conditions. Hilly conditions will result in lower figures than relatively flat roads. Adding or subtracting weight will affect mileage.
 
If your truck is carrying around a lot of cargo weight, it will not deliver the "AVERAGE" mpg. One that is near empty may deliver better than average.
 
A GPS will most likely reveal your speedometer is reading a bit higher than actual speed, but your odometer will be pretty much dead on.! I can't explain it, it is just the way things are sometimes.
 
Anytime anyone contemplates paying extra to get a few more miles per gallon, they need to do the calculation before the fact, rather than after the fact!
 
To drive 100,00 miles:
Consider 15mpg with gas $2.50 gal.. It would cost $16,667 for fuel. Now 22mpg with diesel at $2.70 a gal would cost $12,272. Diesel will save about $4400 in fuel.
 
I used a 20 cent higher price for diesel because of prices in my ares. Yours may vary.
 
My understanding is that there is a slightly higher maintaince cost associated with diesel and possibly additional additives that gas engines don't require.
That would make the above $4400 figure lower.
 
Even if the savings were the $4400, it would take over 200K miles to break even for an extra $9000 purchase price.
 
Keeping in mind that higher or lower fuel cost will affect numbers.

And really you must consider that the extra $9000 purchase price for a diesel Sprinter is an upfront cost and that the $4400 fuel savings are received over the 8 or 10 years it would take to drive the 100,000 mi.
 
This is a "time value of money" calculation, which I can't do without some investigation, but it can be approximated as an interest calculation. If you buy the 15 mpg gasoline Ford or Chevy van and put $9000 in savings at 5% interest compounded anually for 9 years, it would turn into $9000(1.05)^9 = $9000(1.55) = $14,000.
 
Of course, a Sprinter has features that the Ford and Chevy vans do not. When the gasoline Sprinters become available you will be able to separate the premium for a diesel from the premium for a gasoline Sprinter. Very possibly it will turn out that a gasoline Sprinter may make more financial sense than a diesel one for many who want a Sprinter.
 
Also it may be an important value to you to save fuel whether it makes economic sense or not. Note however that in doing fuel use comparisons between gasoline and diesel you should really use the weights of fuels and not the volumes. Diesel fuel is 15% denser than gasoline, (and gasoline has 87% of the density of diesel fuel). So to correct the mpg of a gasoline engine for the difference in density you'd multiply the gasoline mpg value by 1.15 to get a corrected mpg value equivalent to that of a diesel. Therefore, the 15 mpg of the Chevy is corrected to 17 mpg for comparison to the diesel value of 22 mpg for true amount (that is weight) of fuel used for environmental purposes. You do not make this correction for cost because motor fuel is sold by the gallon and not by the weight.

Yep!
 
To be fair, if fuel should go considerably higher and the vehicle was to be driven for several hundred thousand miles during that 9 years, the savings of a diesel would become apparent.
 
Of course there may become an even greater cost difference at the pump between diesel and gas, if/when Bio-diesels are forced upon us and higher cost plus poorer mileage kick in.

Fuel cost saving of diesel vs. gasoline by jim314

So in the previous post (#58) I calculated the original est $9000 in purchase price savings of the gasoline engine would accrue $5000 in interest over 9 years, but to compare you would have to assume that the fuel cost savings of a diesel would be saved and put at interest each month or year. Over 9 years this would grow to some amount which could be calculated, and which would be in the diesel's favor. That is, one would subtract this amount from the $14,000 advantage for the gasoline engine to get a net monetary gain for the gasoline engine.

True! There is a big IF! IF the savings were actually put into a savings instrument.
 
Figured on a yearly basis of 11,111 miles driven, the diesel would save $488 a year. The $9000 would grow $450 the first year.
 
At 22,000 miles a year the diesel would save $976 and the $9000 would still have only grown the $450.
 
If that $976 were saved in a 5% instrument and the diesel maintenance cost are not overwhelming, the diesel is a winner.
 
As stated earlier, the diesel needs lots of mileage to be worthwhile.
 
Average homeowner that wants a van for trips to Home Depot or occasional camping or towing would probably be better off with the 15 mpg V8. Me thinks.
 
Maybe Dodge will slip a V8 into it while Mercedes is not looking!

The 2007 Sprinter will be available with a gasoline engine--a 3L V-6, I think.

money saved always has a time-value (interest rate equivalent) whether you put it into an "instrument" or not.
 
What you are looking for is a MARR (minimum accetable Rate of Return) for your investment, and time-value of money is always a part of that equation. More money saved earlier is better... and money saved over time is less so.
 
Since I got my Sprinter at a $7000 (+/- $500) discount, I don't have a problem getting my investment back...
 
Money saved on maintenance, extended service intervals (if efective), and reduced shop down-time are more intangible in nature when compared to MPG and initial cost.
 
At least in the passenger model, I don't see as big a difference in the Sprinter compared to a GM or Ford product for price on a 3/4 ton or 1 ton model basis. That is, of course, if you don't mind (or, like me, prefer) Rubber Mat flooring and simple/sturdy (Sprinter) instead of carpeted and plush (which most GM and Ford vans will be).
 
My last Astro/Safari listed for nearly what I spent on my Sprinter and the Sprinter still gets better mileage than the Safari mini Van!
