If you only use the vehicle for short trips of 15 min or less then you will lose about 10% from the 'norm'. This is true for all vehicles on the road. It's just more obvious in a Prius. |

Replying to: kdhspyder (May 04, 2008 10:09 pm) Obviously you are very knowledgeable on Prius issues. Just two questions: a) assuming no gas spills, what are the adverse results of "topping" the tank, that is the extra 1-1.5 gallons after the shutoff engages? b)is the trip fuel gauge for the Prius inherently flawed, or are the discrepancies due to bladder issues, i.e. an elapsed reading of 57MPG,manual calculation of 50MPG?

Replying to: cheryl06prius (May 05, 2008 10:05 am) Keeping stats is not "obssessive-compulsive" it helps in learning and forming an opinion. Personally for me it only takes less than a minute to log it every two weeks. Being educated about the car helps to give answers to questions like the ones you posted. a) other than the problem with gas spills you may also damage the charcoal filter and bladder by overfilling the prius. This can be an expensive replacement in case it happens (do a search on the subject at www.priuschat.com). If you for whatever reason overfill drive the car some distance to use up the overfill rather than parking it. An extended period of the overfill condition will increase the chance of the damage to your charcoal filter system etc. b) Most people call the Prius gas gauge as "guess gauge". Most gas gauges tend to be not very accurate and serve as a guide only. With the Prius the added complexity is the bladder as you pointed it out. It expands/contract with age and fluctuations in temperature. These factors result in the difference between MPG calculated and displayed on the MFD. Tank to tank variations can be significant but long term they should be pretty close. Also some pumps shut-off earlier than others and the rate of speed you're filling up also effects how much you're able to put in the tank. Hope this helps and enjoy your Prius. Just drive it! Gabe

| I live in WV, in mountainous terrain, in a city of 20,000 people with lots of congestion and stop and go conditions. I can't go more that 2-3 blocks with sustained speed at any time or any place. Mileage with my other vehicles no matter the size or the brand has historically been around 15 mpg over a tankful. 90% of my driving is in the city and I'm pointing my question to those of you that might have similar or at least, sort of similar, conditions in your town or area. What is the worst expected mileage that you could surmise for my conditions? Would I get at least 30 mpg?? | |

I am considering a Prius but I have been hearing and seeing reports that the mileage is around 35 - 40 MPG under actual conditions which in my opinion can be matched by a regular honda civic. Can someone who owns a prius share some information on the actual mileage of the car in real time driving conditions. Thanks.
