Gary... are you hammering down on the Tiger throttle?
The 11.0 gallons per hour is higher than the book figures and gives you
13.7 mpg in the Tiger (statute miles)
If you got 16 mpg, your fuel cost would be $170, a little closer.
Your point-to-point Tiger speed is 131 kts.
Do you think the Tiger burns that extra gas in the climb to altitude?
What altitude and rpm do you cruise at for 11.0 gph?

PS ...it's more fun in the Tiger anyway....
PPS my comparison was Tucson to Bakerfield.
10-11 hrs by road - travelling thru LA - could add hours is badly timed
3.7 hours by Tiger - could fly around LA airspace....
The Tiger made a weekend trip possible.

Yes, that's pushing it. During a climb, i can burn 19.5 gph at near sea
level. If I throttle back to stay with a Cheetah/Traveler, I can get the fuel
burn down to 8 to 8.5 gph at about 128 to 130 knots true. The
Cheetah/Traveler is burning closer to 10 gph.
I fly to Lancaster at about 7500 to 9500 feet. I climb in stages to about
the halfway point because the plane is heavy with fuel. Level off at 3500
after take-off, 5500 at Columbia, 7500 at Fresno. On the way back, I have=20to
climb to 7500 to 8500 to get over the Tehachapi Mts. Then, I use the altitude
to get back the speed on the way back to Auburn. P pretty much descend the
entire trip, 500 feet at a time. By Columbia, I'm down to 4500 feet and hold
that to Placerville. Pattern altitude at Auburn is 2500 feet.

I didn't know about this thread before I left or I'd have taken better
notes.
I just drove to Poughkeepsie, NY from Wilmington, DE 210 miles according to
Yahoo vs. 140 NM via airnav. It took about four hours each way to drive it.
(nice drive going up Friday but nasty rain coming home; thats why we drove)
I burnt 19 gal of 87 octane in my Toyota Tacoma 2WD pickup. When I was
calculating a flight plan earlier in the week before I left I was
calculating I'd burn about 23.4 gal of fuel; 1.8 hours @ 6.5 GPH. I have the
auto fuel STC so the fuel used would be the same, only the qty different.
Add in the cost of the tolls for the drive and the tiedown fee if charged
depending on where I landed (I intended on going to KPOU) and the cost
difference would be a dinner out. My time is worth more than that. BTW that
is with an AA1B with stock O235-C2C DMA wheelpants and aux fuel tanks... No
need to refuel unless we did a fair amount of sight seeing while there.
I'm hoping to fly up again soon as I've been told the scenery flying up the
Hudson is truely awsume. Dicky Betts is playing at the theater we saw Blues
Traveler at Friday night sometime in May so a trip next month is probable.
If the WX is right I'll fly... Hope to have the IFR ticket soon... Any Blues
fans/Grumman pilots out there in the Northeast/MidAtlantic?

I've never done the math (just like I've never totaled my annual operating
costs) but this fits with my experience. I always use the large-SUV analogy
when speaking to non-aviators.
Unlike Gary's factor of 2.5 driving to flying time, I have found 3.0 to be
accurate. Most likely that is due to my east coast flying where major roads
between any 2 cities are less common. I have also been able to live within
a 5 minute drive to my airport.
Again, afraid to do the math, but I plan to seriously re-evaluate my general
aviation activities when 100LL averages $5/gal. Which entrepreneur is going
to invest in obtaining the MoGas STC for Tigers?

I just got back from flying out to my mom's place for the weekend San
Diego to Tucson, out Saturday, back Sunday. Decided to go on Saturday
morning.
Out 2:45, 23.6 gal
Back 3:00, 27.8 gal
Round Trip:
By Tiger: about 6 hrs, $210 gas, no TSA silliness
For comparison:
By Miata: about 12 hrs, $120 gas, Mojave desert
By Southwest: about 5 hours, $212 ticket, "please take off your shoes"
Twelve hours in the Miata across the desert? I'd shoot myself.
So, until Southwest starts letting me sit left seat (ok, Id settle for
right seat, and I do have a commercial multi, hint-hint) I think Ill be
sticking with the Tiger.
Michael
Ps.
I do agree with others who have written that as fuel costs increase, we will
become more "aware" pilots.
NMPG vs GPH? Enjoyment vs Distance? Flexibility vs Cost?You decide.
On this last trip, I had a 10 knot tailwind one direction, and a 30 knot
headwind the other. We have a lot more control over our flying than we
think...
