How to Get a Higher Gas Mileage on Prius
53 MPG is not bad at all. Here are some tips that helped me improve my gas mileage from 43.3 MPG to 62.1 MPG.
1. Don't go over 65 MPH on the freeway. The fuel efficiency drops drastically between 65 and 70 MPH. You will get the best gas mileage at 55 - 59 MPH.
2. USE CRUISE CONTROL on the freeway. You WILL see an immediate result with this.
3. USE CRUISE CONTROL in the city as much as you can. You can get on cruise control at 25 MPH or above.
4. When you accelerate, don't slam on the gas. Go easy and gradual. If you are at 25 MPH or above, you can use the "up" and "down" shift on cruise control to accelerate or decelerate.
5. If you see a red light ahead of you or when you KNOW you'll have to stop soon, let go of gas and start coasting. The less you have to rely on the brake to stop, the better gas mileage you get.
6. You won't get as good gas mileage when your outside temperature is below 40 F or above 90 F. The idea temperature is between 50-70 F.
On your next trip, try going steady at 57 MPH with cruise control on the freeway while having your "Trip Information" on your screen and see what it tells you. I think it will raise your eyebrows. Good luck :)
Currently sitting at 61.7 mpg
On this tank of gas, I have gone 620 miles with the average reading 61.7 and I havent even started using the last fuel "bar" yet. I have almost 20k miles on my 2006 Prius. Like almost everyone I've heard talk about, I have experimented with trying to find the best gas mileage. I have 2 secrets: 1) I drive in "neutral" as much as possible and 2) when I drive on the highway, I draft behind big semi trucks, or just a big truck/suv can help too, but not as much as a semi truck.
I drive mostly in the city and usually dont go above 50 miles per hour. I dont have a lead foot and accelerate at a casual pace. What I mean to driving in "neutral" is by looking at the energy monitor, the one with all the arrows. Once I slow down to 40 miles an hours, I carefully place my foot on the gas until there are no arrows at all. This is tricky and can take a little get used to, but since I've started doing it, my MPG has finally gone above 60, and is still climbing. It was always dancing between 56 and 58. Now every time I drive my car to work (26 miles), it keeps increasing another .1 to .2 MPG.
When I do drive on the highway, I drove from West Palm Beach, FL to Jacksonville, FL and drafted almost the entire way. My MPG rose from 57 to 60 by the time my trip was over. When drafting, a lot of people say it's not safe, but I found that you dont have to draft 10 feet behing the semi's. I'm far enough away that another semi could fit between me and the one I'm drafting on. I cruise at 70 miles per hour and watch as the average MPG actually goes up. The yellow bar graph is solid at 60 to 65 all the way across.
It takes discipline and patience, but it works.
