I live in Seattle. I got my Prius about a week ago and its been great. However, I see an average of 43mpg. I haven't driven much, just 300 miles since I got the car. I dont dry much on freeway. Any idea why so low milage? I will greatly appreciate any insight, tips, tricks...

You won't get the most fabu mileage for a few thousand miles. Tires, car, driver, all have to get broken in some. Also, the weather is a factor. Warmer weather, better mileage. Be patient. You'll get there.
We've all asked the same question.

These conditions can reduce your milage:
Low tire inflation,
Cold weather,
Short trips,
Low and high speeds,
Hard braking.

If you are expecting to get the milage on the window sticker you should lower your expectations. I would suggest that you set a goal of about 50 mpg.

I think that it is too soon to start worrying.

shart trips are the #1 killer

You don't get better than 25mpg for the first 5 minutes if the engine is cold. When you need to make a short trip, try to add other errands to it. If your dropping kids off at school, go ahead and run by the post office, grocery store, etc while you are out.

Driving habits will affect mileage, but to a lesser extent than you might think. I frequently stand on the throttle hard and still get 46 (avg this tank). Most of the aggressive acceleration is to show whichever nay-sayer that's in my passenger seat at the time that the Prius is not a dog and actually is more peppy than a LOT of Sedans out there.

Anyway, if you can combine the shorter trips into one you will see better mileage.

Well, my dog is very fast. She corners so quickly and so tight that she gets grass stains on her shoulders. Many automobile drivers would envy her relative speed and acceleration.

In Florida, for example, a greyhound is considered a racing animal, and cannot be classified as a "pet." Incidentally, a recent news article said that some owners/rescuers are trying to change the designation.

I have a friend who have 2 of them. They make great pets, even though they made a racetrack out of the back/side yard. Most counties license them like any other dog.

My neighbors have 2, and they're really sweet (unless my dog is nearby, then they all have a snarlfest). I wonder what the news report was talking about, though, when it mentioned trying to change the law to get them registered as "pets." Oh well. :)

SeaPrius: Might be another case of "NSD". Any oldtimers remember this from the old Yahoo Prius group?

"NSD" is short for "Natalie Style Driving". Several years ago, when the Prius was new to everyone, there was a nice woman named Natalie who only drove her Prius on short trips of a few miles each, with about at least an hour between trips.

Since early model US Prius don't have the "thermos bottle" feature which now keeps new Prius' radiator fluid warm, Natalie got really low mileage for a Prius (much lower than what SeaPrius reports.)

I suspect SeaPrius may be seeing the result of a similar driving style, combined with the current relatively cool weather in her part of the US.

It's likely you'll see your mileage improve somewhat as the weather warms up, but if (if) you typically drive like Natalie, averaging around 45 - 50 MPG in your shiny new Prius is probably about what you should expect.

And, as others have probably suggested, you might try keeping around 40 (or 42) psi in all 4 tires to see if that helps your mileage.

In any event, you're still getting about twice the mileage of most of the other vehicles on the road!

Enjoy your new Prius!

Proper tire inflation makes a big difference

Due to chilly, rainy weather I had procrastinated on checking tire pressure and was averaging around 43 MPG. When I finally paid $0.75 for air at my local BP station :)x) and added about 3 psi to each tire to get them up to recommended pressures, my MPG immediately rose to around 47.

But whatever happened to free air pumps at gas stations? They seem to have gone the way of the dinosaur around here!
