Prius (2010-12) Fuel :: New Tires Lead To Drop In Gas Mileage
Last October I needed new tires, so I had Michelin Defenders put on my 2011 Three in place of the OEM Firestones. The Michelins perform well and are nice and quiet, but...
My gas mileage (both indicated on the dash and calculated) has dropped by about ten percent. In researching the two brands of tire, I found that the OEM Firestones are rated at 836 revolutions per mile, and the Michelins are 839. I'm wondering if this is the reason for the apparent change in mileage.
Prius (Gen 3) Fuel :: Mileage Drop (0.8 Mpg) While Not Moving
I turned on the car, CONS showed 56.0mpg,
backed out of the garage (about 20 feet) 55.8 mpg,
waited for the garage door to close 55.0 mpg (ICE started),
got to the end of the street (about 200 feet) 54.0 mpg
outside temp was 51F, humid, cloudy
had about 90 miles on new tank of fuel
I know you get big swings in fuel economy when you reset the trip on fill ups but I just thought it was funny that the mpg would drop 0.8 mpg while not moving.
Prius (2010-12) Fuel :: Sudden Drop In Gas Mileage
I commuted to LA 2-3x a week. The mileage on my car is now at 90k. I have had an average of 40 mpg since new, but suddenly it began to drop. We took it to our local Toyota dealer and was told it was most likely a cable that needed to be cleaned. That was $160. It didn't work.

I am using a 2012 Prius and I was running around 23KMpL average. For sometime I am seeing my mileage around 17 - 18 KMpL. What could be the reasons for this ?
The only change happened in between is that I had a accident which I had to replace the front buffer.
Prius (2010-12) Fuel :: Gas Mileage Drop - Averaging Between 41 And 43 MPG?
I bought a 2010 Prius II (150,000 miles on it) about two weeks ago. In that time the car has been averaging between 41 and 43 MPG according to the computer, and I calculated 41.3 MPG at my last fill up. I am concerned about the MPGs. I bought a brand new Prius in 2012, it was a III model and '12 year. That car always got 48 highway, and 50 in the city. From what I understand, the 2010 and 2012 models have the same engine and transmission set up and the only difference may be the software.
So my questions are; why am I getting 7 to 9 MPG less than my old (newer) 2012 Prius? What to do to get better mileage, but what actually worked? My checklist of repairs include; check 12v battery, change out spark plugs, just changed air filter, check brakes, oil change (using Mobil 1 full synthetic 0w-20), what else should I check/replace/update,
Prius (2010-12) Fuel :: Why Does Mileage Drop At Least 2 Mpg When Raining
It seems that my mpg gauge always drops by at least 2 mpg when it's raining, even if one goes slower because of the rain. Why is this?

I live in the suburbs, so I do a lot of stop and go driving. For the longest time, I would typically get 25 or 26 mpg city, as per the gauge. I would see the number climb to 41 or so in constant highway driving. I am pretty sure the fuel tank is about 10.5 gallons or so as when the low fuel light comes on, and there is only one bar left on the gas gauge, and I top up the tank, I never put more than about 9.5 - 9.8 gallons in.
All this being said, in the last few weeks I have seen a severe drop in MPG. The gauge is constantly reading about 19.5, when I hit the expressway it will climb a bit, but when I compare the miles driven to the bars on the gas gauge, the bars used to drop at about 20 miles driven, now each bar will drop at around 13-15 miles driven. We are having some extreme cold here in the midwest, as opposed to last winter when I bought the car.
Prius (Gen 2) Fuel :: 2007 - Mileage Going Down
We have a garden variety 2007 basic Prius. That description will tell you that I'm no Mechanic. The mileage was between 40 and 43 MPG for years. Now it has suddenly dropped to 33 and 35. The average temp here in Florida is fairly consistent at above 60 F, so that is not it. Oil changed at the dealer, and not overfilled. Tires at the right pressure. Worn to perhaps 50% of their avg tread life. Also, I had the 12 Volt battery replaced at the dealer a few months ago, and no change. Is there a way to check?

The stock 265/75/16 tires need to be replaced and I was considering swapping 285's on the stock wheels. Will I notice an increase in fuel consumption? I realize that calculating mpg will need to be adjusted due to larger tires since the speedometer will be slightly off.

View 9 RepliesTouareg :: Ticking Sound After Mounting Summer Wheels And Tires
With average temperatures going over 10 C, it's time to switch tires, so I did. I have a set of 20" ATP Inox wheels with Nokian NRVi 275/45 tires, that are only used for the summer (in the winter the stock 17" canyons are used), the wheels and tires are not new, they've been on the T last summer as well without any problems.
But now, I hear a ticking noise in all 4 wheels or tires when driving. The sound doesn't stop at higher speeds (only more difficult to hear due to wind noise), and it occurs on the same spot in every wheel rotation. It's like there's a big nail in all 4 tires, but: there isn't one, nor anything else, and there's plenty of thread left (> 1 cm).
The noise stops sometimes when braking or turning. I contacted and visited the dealer, and he couldn't find anything but assured me that it couldn't be that big a problem. What I checked:
- air pressure (3 Kg/cm rear, 2.6 Kg/cm front)
- all bolts properly tightened
- no nails, stones, whatsoever in the tires
- no loose cables, brake pads, or things like that
- thread wear is ok
- I have no TPMS so no lost sensors inside the wheels
If the problem persists, the dealer will take the tires off of the wheels and check inside, but according to me it's very unlikely that there's something inside all 4 tires.
Prius Plug-in 2012-15 :: EV Mileage Sudden Drop
I was driving up a hill today at about 30 mph with .9 miles remaining showing on my EV battery meter when all of a sudden it drops to 0 EV miles remaining and shows only 2 of the battery level bars (which is very very low), and the engine of course turns on. What happened?
I promise I did not push the EV power bar over its threshold. I monitor that like a hawk. I also know for a fact that it jumped from .9 to 0, because I watch that part like a hawk. This part of the trip is near the end of my drive home and I've done it about 50 times so far with no issues. With .9 miles left at that point on the hill I have always been able to make it to my driveway with .4 or .5 remaining, so this is very odd.
Prius (2004-09) :: 2005 - Cause Of Sudden Drop In Gas Mileage?
My '05 Prius has been going strong with just passing the 200k mark recently. However about 2-3 weeks ago after I replaced the PCV valve, I started getting really bad gas mileage. I'm talking about getting an average of 45 mpg in city/highway combo down to 30 mpg. Filled up my tank twice from empty so I'm pretty sure it's not just bad gas. Highway driving does slightly better than city.
Today I noticed that my acceleration from stop is just absolutely terrible. The car responds really slow and sluggish and takes a while for it to realize I want to go. Low speed doesn't get good mileage at all. It seems I get normal mileage at almost 65 mph, not sure why.
I don't think the 100 degree weather we are having here in Texas is causing THAT much of an effect because last year and two years ago during 100 degrees, gas mileage was normal. What to check? I searched and most talk about cold weather. I have a relatively new 12V gel battery so I doubt it is that but I can try disconnecting it.
Prius V :: After Changing Tires Mileage Drops?
Other than during cold winter weather, our 2+ year old Prius has been averaging 51-56mpg all around. Our tires needed changing and my spouse went to a tire dealer. The dealer recommended Cooper tires, a model supposed to get 50k miles. Almost immediately we now average 45-46mpg.
In looking back, we didn't buy tires that accentuate mpgs. Is there anything we can do short of selling the tires? And are they makes and models we should think about when it's time to change the tires?

View 18 RepliesPrius (Gen 3) Fuel :: Fuel Mileage Reduced When Driving In Rain
We gave the Prius a good workout in the rain for the first time today. Central Florida has been having serious amounts of heavy rain, creating water covered roads in our area. Normally the digital fuel mileage display shows around 55 MPG for most of our driving. However today it dropped to the upper forties very quickly.
We were running the wipers on continuous (low and med speeds), the AC (defrost) was running to keep the condensation off the windows, and the headlights were on. I wonder if the extra resistance of the water on the road also had an effect on the fuel mileage.
Even though we hit some fairly deep water and created large amounts of splash, the car tracked straight, the brakes worked well, and the power was totally uninterrupted. Other than the poor fuel milage we were impressed.
Prius (2004-09) Fuel :: 2008 - Sudden Drop In Fuel Economy - Water Leak?
I have a 2008 prius. Usually it gets me around 52-55mpg, I've had it since January. Since a couple of days ago its not giving me anything above 49. I know thats a normal number, but considering the fact that its usually quite a bit higher I'm wondering what the cause of the drop is. Also around the same time, when I pull out of my driveway I notice what appears to be a bit of water leakage. Its under the vehicle in the front center, and it only happens when I start the car for the day and pull out of my driveway (its on an incline).
