Save a tree, go by RV!

[N941WR]

I was running some numbers from a trip we took on Saturday and thought I would share them with you:

By AIR:
Distance: 241.3 statute miles
Time: 1:40
Average MPG: 34
Fuel used: 7.1 gallons
Average hourly fuel burn: 4.3 GPH
Average ground speed: 145 MPH (Strong head winds)
Fuel Cost: $30.18 (@ $4.25/gal)

Average cruise power setting: 65% ~ 88 HP

Here is where it gets really interesting...

I checked with MapQuest to get the numbers on the trip, had we driven, which we had done a number of times. Here are those numbers:

Distance, if driven (Map Quest): 342 SM
Average time to drive: 5:28
Average ground speed: 62 MPH

If trip is taken with Nora's Honda:
AVG MPG : 24 MPG
Estimated fuel: 14.25 Gallons
Estimated fuel cost: $44.18 (@ $3.10/gal)

If trip is taken in my Truck:
AVG MPG: 19 MPG
Estimated fuel: 18 Gallons
Estimated fuel cost: $55.80 (@ $3.10/gal)

I'm curious how clean my O-290 runs with the duel EI w/ the wasted spark ignition and leaned out...

With burning that much less fuel than either of our vehicles, taking the RV might have just been the "green" thing to do.

Good numbers Bill.

One thing jumps out at me though, you may want to get that Honda looked at. 24mpg Our civic gets 41mpg

Brian,

Nora drives a '98 Honda Trucklet AKA CRV and with the AWD, 24 MPG is about as good as it'll get when driving through the mountains on the way to Grandmother's house, which is what this trip is based on.

I was just ribbing you. Plus mileage like that helps justify the RV, not too mention to fun factor.

[N941WR]

Not a problem Brian.

But it looks like you should drive that trip and not fly...

If trip is taken in hydroguy2's Honda Civic:
AVG MPG: 41 MPG
Estimated fuel: 8.3 Gallons
Estimated fuel cost: $25.86 (@ $3.10/gal)

[hydroguy2]

Yeah but, what's the fun in being a mindless drone plodding along with the other ground pounders. We flew a C-182 gas guzzler for breakfast the other day....just for the fun of it.


must get RV flying

I'd gladly pay an extra $5 to save nearly 4 hours

I don't know why I stay awake at night thinking about such things, but I do...

When you figure in the material, energy, etc. involved in building an airplane vs. building a car, even HyrdraGuy's Civic, I wonder what the net-net it the "environmental impact" of taking the RV over the car might be. It is possible that the RV is significantly more environmentally friendly than the car. More so, if I were burning auto fuel.

That would be some interesting numbers to know. Anyone?

OK, I can go back to sleep now.

My wife drives a '97 CRV. 22-24 is about the best it gets. What's interesting though, is I have '97 Isuzu Hombre' (AKA Chevy S10) that I wound up with in a trade that makes 24-25 mpg.

Nice numbers! I probably won't go with a 290, but that's motivation!

I typically get between 41 and 44 MPG, but my 90-day mileage average is actually low now because of winter gas and cold weather. In the winter I'm well into the mid 40's.

I keep a MPG log here: http://www.gassavers.org/garage/viewgaslog/12?
