Did some math. I think you will find this interesting.
As many of you know. I replaced my 5.0 liter F-150 with a 1.5 liter Fit. Well, I have put enough gas in the Fit to get some decent averages to compare to the F-150. Here is what I have found:
1994 Ford F-150 (17 gal. Tank) Average distance per tank: 272.53 miles Average gallons per fill up: 15.877 gallons Average cost of fill up @ $3.63/gal: $57.63 2007 Honda Fit (10.83 Gal. Tank) Average distance per tank: 375.52 miles Average gallons per fill up: 9.357 gallons Average cost of fill up @ $3.63/gal: $33.97 Drum roll please... The Ford / Honda Difference Average distance per tank difference: 102.99 miles Average gallons per fill up difference: 6.520 gallons Average cost to fill up difference: $23.66 I am very satisfied with the savings. I believe this vehicle will actually pay for itself. :thumbup: |
Nice! See, math IS fun:thumbup:

Awesome! Glad to see you are saving some serious dough. How many thousands of miles are you going to have to drive before the Fit pays for itself? I have found this to be a more useful tool in conceptualizing "savings."
For example, I've considered buying a small, fuel effecient car as my daily driver. Unfortionately I determined that I would have to drive that car for a very, very long time to pay for itself. Maintenance cost+higher insurance+payments-trade in...etc etc. I have a feeling that your upgrade is enough that you will end up breaking even alot quicker then I would. (I don't know your cost or trade in value to calculate it myself). Congratulations on your upgrade! When its time for me to get a new vehicle I think I'll likely go your route and go smaller and for FE. Have fun with the new vehicle...and with that money you will save. |
Average saved every 375.52 miles driven: $45.44

More math for more fun:
Cost per mile: F150: $57.63/272.53 miles = .2114 cents per mile (gas only) Fit: $39.97/375.52 miles = .0904 cents per mile (gas only) So, by driving the Fit you're saving 12.09 cents per mile. Over 12,000 miles you saved yourself $1450.80 in gas only. Depending on what you paid for the Fit, difference in insurance, repair costs, increase in fuel costs etc. You could be driving for FREE (compared to the F150) in 5 or 6 years. |
I love you guys! Ok, I will be open with you fellas. I paid $9,900 for this 2007 Honda Fit. Interest rate at 4.99%. It only had 65k miles on it when I bought it. Now it has 68k (give or take). Full coverage on the Fit is $40/mo. I carried liability only on the F150 and it was $23/mo.
SO, do more maths and figure out when the car will pay for itself! |
You also need to look at other parts of owning an F150, tires are a good example, tires for an F150 start at $96 each and go up to $140 or more each, tires for the fit start at $57 each and go up to $81 for the expensive low rolling resistance tires of course $67 for cheap LRR tires.
The fit also holds around 4 quarts of oil where the F150 is 6 quarts, so a truck like that is going to cost more all around to own and operate. |
About $120 per thousand miles in fuel savings or $12k per hundred thousand.

This is great and millions more need to do it but I wonder why now? Why not 2, 10, 30 years ago? :confused:

Because it didn't matter much back then to most people. You know things are changing when today's Yahoo page brings about hypermiling techniques as an article.
6 Driving Tactics to Save Gas This Summer - Yahoo! Autos |
Yahoo practices its usual stellar journalism. I had expected better than base fearmongering from Popular Mechanics, though.
Quote:
I'm sure that a search of Popular Mechanics will show at least one or two solid facts about engine braking. Nice job, guys, and thank you so much Yahoo, for giving this crap a wider audience. Yes, it's good to put out the word that people can save a lot of gas on their own. It's better to hire a writer and do some research. |
Jesus, if I am coasting downhill in neutral, I would use a downshift to control my speed if it became excessive. Pick the gear to maintain the desired speed.
Back when most of the laws were written, the Plymouth's with freewheeling had mediocre synchronizers at best if at all. The freewheeling had to be engaged or disengaged when the vehicle was stationary, and the brakes were very marginal at best. Combine that with Route 33 or 50 east through the mountains of Virginia and West Virginia and you have the recipe for a disaster. These days you can downshift your Honda into 5th, 4th, or even 3rd at 70 MPH down a 7% grade, or just slam on the brakes. Even without either of those options your steering and handling would be light years better than the old mid 30s sedan. regards Mech |
I'm trying to remember the last time I had to accelerate out of a potentially bad situation, especially one going downhill. Ummm.... nope, none in the last 30 years anyway.

Inbetween people forgot all about it. So what's the tipping point? Probably not dollars/gallon. Not when you see people filling up at a station that's 20 cents/gal higher than another station 2 blocks down the street. Probably not Peak Oil. That's been known since the '70s and we all know how consumption has been between then and now. Must be percentage of household budget. Say, 1000/mo total budget, 200 of it for fuel? Doesn't really matter if fuel is $1/g or $4/g, the household will adjust miles driven and fe of vehicles used to consume that 200 no matter what? Yes, I think that is it. |

It works far better with a MC than with a car. Quote:
If it's that steep that you need to use engine braking to prevent a runaway, DFCO is fine. If it's not so steep, it may well be enough to coast downhill using no gas at all (EoffC) or very little (EonC) without developing into a runaway - aero drag will control your speed. Well, maybe not for basjoos ;) |
Congrats Dunkler!
Regarding the quoted article: "If the engine stalls", how quaint. Last time that happened in a car I had, it was my Camry and the timing belt had broken. I PUT it in neutral and coasted into a handy parking spot from about 40 MPH. |
Getting back to the math
Quote:
After year 4 when the Fit is paid off and the insurance rate drops we'll assume the cost to own the Fit is the same as the F150. Note that the Fit will be cheaper on maintenance and repair but we don't have numbers to assign to that savings. Now, the cost of the Fit over 4 years = $12962 divided by the estimated savings based on 12000 miles of driving per year at $1450.80 works out to 8.9 years to break even. Since the insurance will continue after the 4 year period, (but drop by $17 after year 4) it's more like 9 years. If the F150 was sold for $3000 the $12962 initial 4 year cost drops to $9962. $9962/$1450.80 per year fuel savings = 6.8 years to break even. Also as mentioned, the cost to maintain will be much less on the Fit so that will further reduce the break even period, but we don't know by how much. It's probably safe to say though that the Fit will begin to payoff at about 6 years or so if fuel prices stay the same. This exercise shows that spending money on a vehicle to save fuel makes sense, but only if you are going from a blatant FSP to a real miser. Cost to purchase a vehicle can pay for alot of gas and could make the purchase folly if not done properly. It seems to make the most sense if you are about ready to replace your vehicle anyway and/or drive alot of miles and expect to keep the vehicle for a long time. |

I imagine that you will save enough on the low mileage fit in maintenance costs (oil, tires, etc) to offset several thousand dollars against the (presumably) high mileage f150 (more frequent and more expensive tires, oil, expences associated with a high mileage truck etc). I wouldn't be suprised at all if your payoff turned ito something like 5 to 5.5 years. |

I would rather write a program to do the math, but in this case Edmunds has a great website calculator that figure True Cost of Ownership.

Dunkler, sounds like you made a really good decision! I wish more people would use a little math in thier vehicle choices. Seems most decisions here in the land of cheap gas are made on emotion.
Hopefully you are getting rid of the F150. For the money you will likely spend on repairs, if you need the hauling capacity you could buy a trailer hitch and a harbor freight trailer and have 1000 lbs of carrying capacity. My harbor freight trailer has seen alot of abuse in the 6 years I've been using it and still works well. It's really ugly now but it more than doubles the hauling capacity of the little truck. It's light too, could easily be pulled by the Fit. |
Hey man, thanks for the encouragement. I did sell the F150 and got out of it what I paid for it! During the couple of months that I have had this Fit, I have noticed a significant decrease in money spent on fuel and an increase in savings! I am so pleased with this car I can't hardly stand it! I am in the process of making some reversible aero mods to this car to get closer to my 50mpg mark in this thread: http://ecomodder.com/forum/showthrea...ead-17883.html

If you're really smart you'll pay as much as you can afford on the loan for the Fit to pay it off sooner. Every extra penny you pay when you make your payments will reduce the payoff time and interest paid. Remember, when you make a payment you are first paying the interest that has accumulated since your last payment, whatever is left over from your payment goes towards the principle. Any amount over the scheduled payment will add up fast in savings. Even splitting your loan payments into 2 equal payments twice a month insted of once a month will reduce your total interest that you will have to pay as well as reduce the payoff time. If you don't believe me ask any banker and they will tell you the same thing. The banks hate it when you make more than the scheduled 1 payment per month since they lose money on the interest they could have charged you.
