Prius (2010-12) Fuel :: Hot Weather Mileage Decrease
I don't have a lot of data yet, but the last couple of times we had temps over 80F, my mileage took a significant hit - about as bad as when temps are below 20F (more than 10%)... Shutting off the A/C doesn't change things much...

Gas mileage as stated by Suburu for the 2015 Outback (2.5 engine) is 25-33 with a combined of 28. Mine has never attained that and it has been steadily dropping. Now it is displays as 19 mpg. It is new and has just under 500 miles on it, and I read that the break-in is 1000 miles. That being said, shouldn't I be seeing better MPG than that?
BTW - I am hoping that I am just not being fair (to the car and to Suburu) and that I'll be up in the advertised MPG's soon after I hit 1000 miles.
Ford :: 1998 - Engine Stumbles In Warmer Weather
I am 2nd owner of 98 Ford Explorer Eddie Bauer V6SOHC. Vehicle is almost showroom condition w/ 70,000 miles and properly maintained.
Problem: engine seems to stumble quite frequently and is most noticeable when ambient temp is above 60*. Highway speeds , 40MPH doesn't matter. RPMS drop but it has completely shut down only twice in the last 9 months.
There are no codes. Plugs and wires changed several months ago, fuel pressure checked by Ford and it's ok, injectors cleaned at dealer, MAF seems ok so I am at a loss. Since there are no codes diagnostics don't work. Except for the issue above, this is a very nice reliable vehicle.
Ford F-150 - 1997-2003 :: Truck Struggles In Warmer Weather But Not Overheating
I've got a 2001 F150 and lately, since the weather has warmed up, I've had a problem. After a few minutes on the road, the engine seems to be lacking power and is running hard. It also seems to shake a bit too. It's not overheating and the gauges don't show signs of high temp. My drive to work is 40 minutes and by the last 10 or 15 minutes it seems to be OK. ... A month or so ago when the weather was cold, I had problems keeping coolant due to leaks but that problem seems to have diminished. I don't know if any of that is connected to the original problem or not.

Above 0 Cel.(32F.) 145 F-165 F. even in summer towing. Winter when it gets -20 my trans temp gets warmer (not towing 165.F or higher) When it gets to -30 my trans temp gets to 175 F. or higher I have never looked at trans temps before on any vehicle that I have owned. I like that these trans get warmer when it is cold out and colder when it is hot out.
View 5 RepliesPrius Plug-in 2012-15 :: Cold Weather Driving (Rattling Noises) - Gas Mileage Down
Today, I experienced the coldest temperatures yet on my drive to work. At one point, I saw a '24F' shown as the outside temperature (although not unusual for April in Minnesota):
Expected: My gas mileage was down a bit. I was impressed it wasn't as bad as I would have expected from our 2005 Prius, though.
I should have expected: On the last 1/2 mile or so, when driving slow on the little bit of EV left while in the forced HV mode, I accidentally accelerated too much and forced on the ICE again (it had been previously on earlier in my 22 mile commute). This time, however, it was different because it didn't shut off immediately. I think the ICE had to do a second warm up. I'll have to watch that more closely next time (darn that cold weather)!
Prius (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.
Scion - Xb :: 5 Speed - Gas Mileage Varied And Fuel Mileage Increased
I've had my XB 5-speed for nearly a year and 10000 miles. It as been dead on reliable and fun to drive. My gas mileage has varied from 26 to 31 in mixed driving and from 32 to 35 on the highway. I use premium fuel only because I can get it without ethanol. My fuel mileage also increased a couple of mpg due to getting the power robbing ethanol out. True it is probably not enough to offset the extra expense but I like not having the stuff in my car. My only dissatisfactions has been with the transmission gear ratios. They are way to low. This torquy engine could easily do with a ratio that would drop about 500 rpm for more relaxed highway cruising.
As it is, though, my XB will go up any hill or long grade without breathing hard! Another is the instrumentation. I don't mind the center mounted set-up but speedometer and trip meter for mpg ratings are both inaccurate. My speedo reads about 2.5 mph high and the fuel mileage read out has about the same error, also on the high side. I have the stock 16" tires. The clutch has a narrow engagement band and can be difficult to be smooth on. The car is fairly quiet, is comfortable and this years hot, humid summer has shown it has one of the best air conditioners I have ever experienced in a car. I thought it might be an electric unit rather than a belt driven compressor because there is absolutely no perceived drag when the compressor kicks on.
Prius V Fuel :: Mileage Decrease From About 43.3 To 38.5 MPG
Recently returned from trip from Austin Tx to Monroe LA. Gas mileage decreased from about 43.3 MPG to 38.5 MPG. A little annoyed by this but I guess I can attribute this to the increased weight in the vehicle. Still taking care in for other thing. Maintenance needed light came on & I assume it may be for a 15,000 mi checkup since it is nearing that mark.

2011 Prius for wife. Mileage has always been upper 40s to low 50s until the last week or so, now she is seeing 35 mpg displayed.
I have asked for a check at fill up. I just pulled the car out to wash it and noticed the engine came on right away, same when I put it back into the garage. In the past we would get part way down the driveway before the engine came on. Also did a code check and no codes found
What are the approximate outside air temps? 40s am 70s pm.
Prius C Fuel :: Mileage Dropped From 45 To 40 Mpg
I've had my car going at 45 mpg the past 2 years. I just hit my 45k mileage mark. I drive mostly on the highway to work so getting 45 mpg is pretty good for me. This last few fill ups, I noticed my gas mileage has gone down to 40 mpg. I thought it was a mistake if it was just once but the last 7 fill ups has been that way. It just went down all of a sudden and has stayed that way.
View 3 RepliesPrius (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?
View 4 RepliesPrius V Fuel :: 2012 - Mileage Is Down To 30.6 MPG
My 2012 Prius v (lowercase v) has about 80,000 miles on it, my work commute is 180 miles round trip daily. I had been getting 40-44 for about the first 18 months of owning/driving the exact same commute. In February I noticed when I filled the tank that the range showed around 370, which seemed odd, it was always over 400. I started tracking my mileage and it declined quickly. By mid-March I was getting a range of 320-340 with each fill up, and calculating MPG of 29-31. The dealer has had the vehicle for over a month now and can't find "anything wrong with it". Ummm, the MPG has dropped about 30%, isn't that something wrong?
View 19 RepliesPrius C Fuel :: MPG Going Better In Warm Weather
I have noticed that due to warmer weather and more Prius C owners that the MPG's are going up. No many in the 40's mpg anymore. I enjoy people posting and obtaining over the EPA of 50 mpg, the 60 mpg figure appears to be fairly easy
to obtain with the Prius C.
On our Prius the last mpg was 52.3 calculated this is real world driving with my wife driving 75% of the time and she does not drive strictly for MPG's.
I believe we should all take a minute and pat ourselves on the back as all the countless gallons of gas we our saving and will be saving for our friends and neighbors who have no choice but perhaps to drive large cars and pickup trucks...
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 (Gen 3) Fuel :: 2015 - Gas Mileage Per Tank
I recently purchased a new prius 2015. When I first got the vehicle and filed up it would say I had approximately 600 miles to go now it says I have approximately 400 something and I actually get a little under 400. So how many miles do you get let tank? Are they mostly highway or town miles? When you fill up how many miles does your car say you have? Also I was wondering how to actually get battery meter to ever say full I can never seem to get the last bar. And when I purchased the car they told me I couldn't go any faster then 15mph in ev mode but I actually can't go any faster then 8 mpg which kind of mashes the feature useless.
View 7 RepliesPrius (Gen 2) Fuel :: Gas Mileage 48 Mpg Around Town And 55 Mpg On Highway
My 2006 Prius used to get GREAt gas mileage - 48 mpg around town and 55 mpg on the highway. Recently and all of a sudden, my mpg's have taken a nose dive. I now get 35 mpg! When I'm on the highway, I barely get 44 mpg. I took it to the dealer and they couldn't find anything so they are insistant that it's my driving, oxygenated gas and/or my tire pressure (even though they didn't check the tire pressure).
My driving hasn't changed; my friend with a 2004 Prius buys her gas at the same station and she's still getting ~48 mpg so I'm thinking it's not the gas; and I am OCD about keeping my pressure constant. (I own a compressor and check the tire pressure A LOT.) I drive 5 miles to work - about 15-20 minutes - on relatively level paved roads. About 2-3 times a week I travel longer distances at highway speed. I wash and wax the car fairly regularly to reduce wind drag. I have noticed periodically when I'm coasting downhill, my mpg's are less than 20 mpg so I'm thinking something's terribly wrong.
Prius (2010-12) Fuel :: Eco Mode And Bad Gas Mileage
Well been playing with all the mode to see what they do and the one thing I have noticed is I get worst mileage under ECO Mode. Why it doing this.
View 19 RepliesPrius (2010-12) Fuel :: Mileage Uphill And Down
So, I was in Wash. State for a while this month and rented a Prius. I decided to check some mileage on mountain roads, and here's what I got. All of these are indicated by the computer, so they are probably 5% or so high. Unfortunately, I did not see either the maximum incline or average incline of these roads posted anywhere, so unless someone else knows them, these numbers are not worth too much scientifically:
UPHILL:
Going uphill on I-90 to Snoqualmie Pass from the West (from Seattle), at 70 mph (the speed limit), fairly steady, with a few decreases for traffic and curves: 18.6 mpg.
Going uphill on US 97 to Blewitt Pass from the north at 50 mph, also the speed limit: 27 mpg.
Going uphill on the Olympic National Park road to Hurricane Ridge, speed limit varying between 35 and 25, with a couple of sections as low as 15 mph: 22.1 mpg. (Maximum incline here might have been 6 or 7 percent).
On the Hurricane Ridge road, I reset the Trip Meter A about a mile from the top (interestingly both segments of the uphill trip registered 22.1).
DOWNHILL, mostly:
The Hurricane Ridge downhill produced an interesting number, because I didn't reset the thing at the top, so I had a mile of 22.1 mpg at the beginning. You go down for about 18 miles, losing about 5200 feet of altitude to nearly sea level (Strait of Juan de Fuca). We kept driving, and at 24.7 miles (so about 6 miles of driving near sea level), the mileage gauge still showed 99.9 mpg. (I took a picture, but it's too fuzzy to put in here.) It was a couple of more miles before I noticed that the trip mpg was down to about 91.
