2010 MPG Stats - Post Them Here

[Motorman]

Plus guys and girls,
According to this RITA | BTS | Table 1-11: Number of U.S. Aircraft, Vehicles, Vessels, and Other Conveyances there are approx. 42 million passenger cars and trucks in the US as of 2009. If 1 million Pri were sold in the US, Pri owners are getting better mileage than the other 97.5% if we get 45-55 mpg.

Damn, so close to two milestones. Just filled up tank and was 2 days shy of an entire month between fillups and was 12 miles shy of getting 450 miles out of tank... Not bad considering the cold weather we've been having.

You are either getting really poor mileage or you had several gallons left in the tank when you filled up.

I had averaged 49-52mpg until i did my 30,000 service....new engine and cabin filters.....now i'm getting in the low to mid 40's.....i bought filters at toyota dealer so they are oem.....

My result, for a bit over 2 years (late Nov 2009-mid Jan 2012), a hair less than 47.0 mpg:
905.1 gal; 42527 miles; 47.0 rounded up to the nearest tenth.

As about 85% of what I do is highway, I will be happy if I reach 48 mpg one of these years.

Travel range:
Home base: Pickles Gap, AR (central Ark.)
Easternmost point traveled: just E. of Indianapolis, IN
Westernmost: Oregon Coast
Northernmost: probably Sequim, WA
Southernmost: Big Bend NP, TX

Hello All,

Got my brand new 2011 Prius III two weeks ago, it now has 433miles and the fuel light is flashing. My driving has been mostly highway with about 20% city. Is this gas consumption OK for the first tank? Thanks.

I wouldn't worry too much unless things don't improve after 5,000 miles. Mine improved steadily over that initial break-in range, even as temperatures remained somewhat on the lower end (daily hi/lo average was 31º for my first 5k) -- my avg speed is 35-40 mpH per tank, and also about 20% city (or less).

Other factors on first tank are whether anyone else drove it, before you took delivery, and if the tank was truly full -- it can be a full gallon down before the indicator moves one mark (depending on mpg).

If your average speed is something over 40 on a regular basis (as reported on the dash/trip odo), and temperatures are on the lower side, you may have to wait until spring to start getting 45+mpg.

Beyond temp & precipitation, acceleration and overall driving habits are big factors, and you'll find that if you're mindful of fuel performance and adjust for it, mpg should improve as a result in time.

I suggest saving your gas receipts so you can calculate actual gallons over an extended mileage range to see how your performance truly is -- my HSI reports 5-7% over what the actual mpg is. I reset TripA at each tank fill, and TripB at roughly 5,000 miles, which works out to about 3 months for me, so I get a quarterly average as well.

Good luck and enjoy

The fuel gauge is very conservative. It started flashing at me the other day at around 450 miles. I filled up about 20 miles later but could only put 9.8 gallons in, when a full tank is supposed to be 11.9.

2010 Prius II, 1st full tank 556.9 miles, consumption 53.1 mpg, avg speed 37mph.
tires are at 40/40, no A/C (February), not much heat either as it's been warm(40's amd 50's). when i filled up the car took 11.3 gals. bottom fuel light had been blinking for 35 miles. I was waiting for it to disappear until i realized i was already on borrowed time. yikes. since that tank i have blocked the bottom (bumper) air dam. no blockage on the upper dam. hubcaps removed (as if that matters)

[pretendersfan]

I am averaging 58mpg!
