low gas mileage

Its all to do with power. No matter what, stop and go driving is bad, and because the engine is so under powered it has to work pretty hard at highway speeds. Having low milage shouldn't be an issue. About the engine not stopping i honestly don't know. All i can say is that 33 in town is pretty good, so unless you talk to Toyota to see if its just a defect, i'd try and be happy with what you're getting. (I have a 1994 F-150 and get only about 12, so do try and be happy) About more road car then town car, i'd say its somewhere in between. At 40mph its great, but highway speeds and stop and go not so much. Hope this helps. P.S. New Prius just released so you might want to start saving... just an idea

Short trips kill mileage on any car. Well maybe not electric. But you obviously still use gas. Remember the engine is still cold and doesn't warm up to optimum operating temperatures. Cold weather only worsens it. And yeah, stop and go not good. Also remember mileage is based on that, mileage. So obviously if you don't drive much you only calculate what you've driven.

stop and go driving is where the prius does the best with mpg but if you are only diving 2 or 3 miles at a time you are not recharging the batteries enouph. you need to drive further than that and you are also not warming up the engine and there fore you are not warming up the coolant in the storage tank. you need to drive more than that and also when you accelerate from a stop be gentle and have the car run on electric only for as long as you can. you should be getting around 40mpg.

If you're running the A/C the engine will continue to run so you can stay cool. The engine needs to run to turn the A/C compressor. Also, if you're using the radio and other electronic devices, the engine will have to kick back on to keep the battery charged up by running the alternator. You should be getting your best mileage in stop and go driving when the Prius is using more of the electric motor than it is the engine.

The gas engine will not shut off unless its completely warmed up - this is to prevent the wear and tear of starting the gas engine cold over and over. Also, as someone already mentioned, if you are not driving long enough to recharge the hybrid battery, the gas engine will not cut off either. How short are your trips?

One of the problems of answering these kind of questions is that we don't have all the facts... The Prius is designed to be a gas saver-- BUT ultimate gas savings is left in the hands of those who drive. 1). Make sure your tire pressure is correct. It is better to err on the higher side than the lower side. Do an Obama! 2). How you drive makes a HUGE difference on the mileage. Do you speed out of stop lights or ease out? Do you speed in general? Maintaining a steady speed and more importantly a steady input of power will help your mileage. Finally what year is your Prius? Is it the first generation or the second?

We have a 2005 Prius with nearly 50,000 miles on it that we bought new 3 years ago. We averaged about 45 mpg over all those miles. Most of them were around town with my wife driving back and forth to/from work - about 25 miles each way. We have also made a few trips of maybe 1,000 miles total each. We also have taken short - less than 5 mile trips to run errands. My experience is that the car does get worse miles on real short trips - I would estimate 40 mpg or so. As brought up by other replies to your question - How you drive makes a big difference in the mileage that you will get. You will get much better mileage if you take it easy on the accelerator and the brake. Try that for a tankful and see how it works. If that does not improve your mileage at least 10% and since you have a newer car that is still under warranty, I would take it to the dealer and explain your problem. The car could be out of whack and now is the time to figure it out and have Toyota fix it on their nickel. TRUST ME on this. We just had our Skid Control ECU - one of 14 computers on the car fail. The part alone was $1600 and we had to pay for t because the car was out of warranty. Good luck -

I have a 2014 Prius that I bought in June '14. It is now February '15 and since December my mpg has decreased from approximately 45 mpg to around 30 mpg. I still drive the same route to work, so I don't understand why the mpg has changed so significantly, maybe it's the weather. I'm going to wait for the weather to warm up to see if the mpg goes back up. If it doesn't I'm going back to the dealer to have them take a look at it because this is a new car and a 1/3 drop in mpg is significant to me.

I have 2013 prius 3...first 12 month are 40~48mpg...but after that milige down to number...to 30~35mpg... I want to couple defferent toyata center.. they say "you are driving so bad... " all my falt... they still advertising that prius have over 40mpg.... Toyota... Do not believe anymore...

So much of Prius driving depends on how you accelerate, brake, and the distance you drive each time you turn on the car. If you all read the driving tips on this and other sites, you might come to understand how to coax the most mileage out of the engine. I bought my Prius in March of 2007, and I still average 52 mpg per fill up. But most of my driving is on rural roads with light traffic, so I set the cruise at 55 and watch the scenery go by. By the time I get to congested areas, the engine is hot and my mpgs improve even more. I've literally saved thousands of dollars in gas purchases since 2007 when compared to my previous car, a '94 Accord, which got 30 mpg. Were my mileage to drop below 48 mpg, I'd be concerned. I've got around 170k on the odometer.

I have a 2010 Prius. I used to get 45 to 47 miles per gallon. Within the past month it decreased to about 30-32 miles per gallon. Driving the same as before. I wonder if it is due to very hot weather, and using a lot of the AC.

Hello I would like to know why my 2010 Toyota prius gives me 28 average

Hi, i would like to know why my 2017 prius gives me a 40 mpg when it spouse to be 55? Thanks

I see a lot of questions on this topic and no answers. My 2008 Prius has gone from about 45 mpg last year to about 35 mpg. Tires at right pressure. Driving same: combination of city and highway driving.

When the aux battery starts going bad the mileages goes down. Its the small battery in the trunk only used to run the computer. Test w a volt meter, should be 13.5 to 14. If any less, replace.

Change fuel injector or clean

I have a 2016 Prius Two and I’m also experiencing the same issue in regards to MPG’s going from 50 to about 30-35. It’s been about 6 months now and I thought by changing the sparks, Air filter & fuel injection clean it would make a difference. A lot of people seem to be having the same issue, anyone find a solution? Btw, The dealer has been no help whatsoever! Any help is greatly appreciated.

Replace fuel injectors , spark plugs or may be egr And clean egr pipe and throttle body

I have a 2010 toyota prius 3 and I average around 63 mpg on my prius. I recommend lots of braking to regenerate the battery's energy and not to much acceleration. Don't do full throttle everywhere because that overworks the engine and hurts mpg SIGNIFICANTLY! stay in the drak green zone as much as you can because thats when you're using the battery. However, if the battery looks low, increase engine speed to the light green zone to recharge the battery using the engine. My prius has 534,781 miles and still does super high mpg using this tactic!

my Prius C averages 50 mpg, but when I drive with air off and windows down, I got a reading of 70 mpg this morning on a 7 mile trip. I drive slow, less than 30 mpg on the back roads do not jump start, but this morning, for the first time, that 70 mph dropped to 39. I turned the air on, drove 7 miles home on the highway, doing 50 mph, and it bought the reading up to 49.8 mpg. car is not under warranty. I have 140,000 miles on it.

I had a 2007 Touring Prius years ago. I bought it used and I was only getting about 30 MPG. A year later the belt was squealing. I brought it to my Toyota dealer and they replaced the belt and cabin air filter. I don’t think the cabin air filter has anything to do with the mileage but The mileage jumped to 45 on the low side and 49 on the high side. My answer is check the belt?

my Prius C has resumed giving me close to 70 mpg on short 7 mile trips with the air off. With air on, I am getting 55 mph, the usual milage. on aa 7 mile highway trip. I think my very low milage experience was due to weather that day close to 90 degrees.

The first five minutes of any trip with a cold prius will get low gas mileage as the engine warms up. This takes longer in the winter. If you make many trips that are less than 5-10 minutes long, you can expect to see low mileage (in the low 30s where I am in NY in the winter). It doesn't matter if it is highway or stop-and-go. Until the car warms up, your mileage will suffer. After the first 5-10 minutes, you should see better numbers. As always, you can improve those numbers with proper tire inflation, gentle driving, etc - but it's not going to change the fact that a Prius gets poor mileage for the first few miles of any trip. This is because the engine stays running non-stop until it gets to normal operating temperature to prevent lots of cold starts which are hard on the engine. Once it's warm, the engine goes back to switching on and off as needed.

My 2007 Prius is giving me 7.8 mpg. When I fill the little tank I check how many miles the tank full gives me. 7-8 mpg that is not good at all. help.

I have toyota prius 2014 3rd generation. Get very low mileage, on high way about 15km/ltr. I have changed the fuel injecter, throttle, spark plug, air filter, gear oil and also change HV battery, i bought new HV battery of Toyota CHR which is very expensive but still no improvement in mileage. If anyone have idea thats what the reason. Normally in short trips it gives 19 or 20 km/ltr but in long journey about 15km/ltr.
