Those are some pretty good numbers. It's cool to think that you can go 38 miles with .7 gallons of gas - I mean, think of how far the average person could go with .7 gallons of gas, maybe like 20 miles or so.

I've been having to drive pretty long (100-120 mile) trips down route 17 in NY for the last week, so I've been learning the route more. At first, I was getting about ~44MPG, and then I had to rush back one day, so it was only 41-42, but the last trip, I got 47 going down and back up, so I'm pretty happy with that.

Yeah, I did a GPS check when I first did the run. Hrmmmm, now that I think of it, the 210 feet is for my other home to work route. I'll bet this route is more than 210 feet. I will have to double-check that number on Friday.

This is my "milk run" MPG, the route that makes up for all my other city-putzing MPG and bad-traffic MPG.

I just checked, and this route has a 434 foot drop, not the 210 I originally cited. Soooooo, on a goldilox day, I am almost positive I would get a "record" MPG.

But, I took it again today and I was reminded of why I hate this route. Lot's of tailgaters pushing me to drive too fast. Everybody follows the 0.25 second rule instead of the 3 second rule. I had to sit by a trucker with a cellphone to his ear. Arghhhhhhh !!!!

Last tank I got 49.0 mpg. I wish I'd filled up right after I got in town after the trip instead of driving around for 15 miles of city driving...it might have squeaked to 50 mpg. This was with a full load of cargo aboard. I'll have some highway trips during the summer without load that should be very very good, but there will also be a lot of city driving in the tanks, usually with 1-4 passengers, which makes for worse FE (though better than if they were in another car).

Hello -

Los Angeles fire weather is helping me out :

Trip: home to work

ROUTE : 10 West -> 710 South -> 105 West -> 405 South -> Exit Freeway => Roughly 27+ miles
----
NET ELEVATION CHANGE : ~210 feet drop
----
SCANGAUGE "CURRENT" READINGS :
62.1 MPG,
0.4 Gallons,
211 Water Temp Max,
27.6 Miles,
2106 RPM Max,
0.6 Hours,
60 MPH Max,
45 MPH AVG
----
IAT READING : Hot Air Intake led to Input Air Temp readings of around 130+ degrees F.
----
WEATHER(.com) :
92 degrees F,
Sunny/Fair,
14.5% Humidity,
37.5 degrees F Dew Point,
30.05 in. Pressure,
----
TIME : ~10:15 AM to ~10:51 AM, ~36 minutes
----
RECENT CAR CHANGES : Car is actually missing rear wheel skirts (me lazy)
----
HYPOTHESIS : None. Just want to reinforce the "good MPG" I get in fire weather. If I had all my aero-mods, this could have been a record. I didn't really have any turtles to follow. Check out that low Max RPM!!!

Nice job

Nothing like a good wildfire to boost mpg!

Hello -

I have the dubious distinction of getting my record on an even bigger wildfire day, :

HYPOTHESIS : Fire weather. Sad to say, but fires mean high MPG. What is really scary is that the traffic wasn't goldilox. I hit some traffic jams on the 105 West that normally would have killed a good run. However, I had such great MPG leading into the traffic jam that I still beat my old record by 1.9 MPG.

17,07 in the Mustang. Thanks to good weather, this is the first time in 26 days I've filled up the Stang!

At the end of June, I started out on a cross-country trip in my Scion xB. There were four memorable legs on that trip.

First was a 75 mpg downhill run from Truckee, CA to Reno, NV, involving a 2000' elevation drop, over a 40 mile distance. At the 35 mile mark, I was still averaging 80 mpg!

Second was a 58 mpg downhill run from a summit to Ely, NV, again over a 40 mile distance.

Third was a 165 mile drive from Gallup, NM to Tuba City, AZ involving no net elevation change. It was a perfect day on a perfect road, climbing mesas that offered long 5+ mile runouts, with no traffic, allowing me to slow down to 35 mph and drag my glides out longer. I averaged 59 mpg for that 165 miles! That's 211% of my 28 mpg EPA combined mileage for 165 miles.

Fourth was my whole drive home from Gallup to the Bay Area. I averaged 51.5 mpg for 1213 miles - 184% of EPA. for over 1200 miles.

My worst mileage was 32 mpg driving at 70 mph to meet some friends. In spite of that, and despite hauling four people and all our gear up and down the length of Florida with cruise control and AC running, I averaged 44.7 mpg for 7238 miles.in the Scion.
