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.

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.

I think I'm getting the hang of this car after 3 months. My mileage has been steadily increasing as the weather has gotten warmer and as I've adjusted my driving a bit. If I drive fairly normally i get about 55 mpg (HSI, ~52 mpg actual). If I'm more careful I get closer to 60 mpg HSI. If I'm really careful I get over 60. My last tank was 61.8 (HSI), and 59.6 mpg from the fillup (see attached). I put 10.13 gallons in the car for 604 miles. I call that 60 mpg, and I'm pretty pleased. This is for a week of normal commuting which includes lots of hills, about 1/3 surface streets, 1/3 state highway, and 1/3 interstates with occasional stop-and-go. It is pretty hot here these days so the AC runs constantly. I have only seen my mileage get better with time so I haven't seen it roll over as the weather has gotten really hot, but that may be that any affect is counteracted by my learning to drive this car.

I am suddenly getting 8 mpg decrease both long and short trips. Rotated tires, checked psi and did an alignment but couldn't find cause. I remember my old car had an engine thermostat and when that was stuck open or close the mpg decreased a lot too.
View 19 RepliesToyota - Prius :: 2012 - Mileage Decrease Upto 50 Miles Per Gallon?
I bought a 2012 Prius new and averaged just under 53 miles per gallon for the first 15,000 miles regularly. I have a long commute so my driving mix of city/highway is pretty consistent. When starting the car one morning there was a fairly loud series of clicking sounds from the engine compartment, which then stopped. From that point forward the mileage has dropped to just under 50 mpg. Same driving habits. I am bringing the car if for it's 20,000 mile check up shortly. Any ideas if something happened to the battery I should ask about? It is still under warranty.

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.
Prius (2010-12) Fuel :: Winter Mileage Very Low 42 - 43?
Temps average maybe around 10-15F in the winter so mileage won't be great. Tires are up, grill is blocked. We're getting about 42-43 on the HSI which means about 40 mpg in reality (I've checked this many times and Toyota is off by 3 mpg on average in our car). But Mike in Maine shows up with a 60+ mpg in 15F temps, and I know my fellow Alaskan, Spiderman, is getting 50+ easily. My commute is more highway than stop and go. I don't use P&G but I'm very gentle with the go pedal. I feel that I should be getting closer to 50 here, even with the temps. Is this too much to ask? Maybe it is...
View 12 RepliesPrius (2010-12) Fuel :: MPG Fluctuates With Weather
Well, for the past few weeks the weather in Los Angeles had been a little on the cool side. I didn't notice the cooler weather, but I noticed that the computer says I was getting around 51 MPG for almost the entire tank (the warning was blinking so I think I used about 10 gallons).
Then today, the temperature rose to around 90 degrees. I noticed the heat. All of a sudden, my computer MPG rose to slightly above 52. I think that would be difficult to do as it must average out the entire tank an extra 1 MPG. And correct me if I'm wrong, but if I got 51 MPG over 10 gallons of gas, in order to raise the gas mileage by 1 MPG in the next gallon, I must get around 62 MPG for that last gallon.
Prius (2010-12) Fuel :: Mileage Dropped After Maintenance
I have 2600 miles on my 2012 mdl II. A month old. I have been averaging 47.5mpg since day one based on miles driven and gas put back in tank at each fill up. I have used only Mobil bottom 87 oct gas.Last fill up got me 48.2, very nice, then I filled up with mid grade 89 oct as it was all I could get then. The next day I was in the dealer for my 1000 mile checkup. when I got out my battery was down to 25%, okay no biggie. Then from there on out I notice my mpg changed alot. The comps used to read 49.1-50.1. Now it reads 42.2-44.1. I drive the same way and my 85 mile round trip to work hasn't changed. My first fill up since the dealer, got me 45.0 mpg. wow a big drop off.

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.

The humidity has an affect on my MPG. I noticed that my MPG went from 49 - 52 MPG down to 44 - 46 MPG when the heat & humidity started here in June. Yesterday a cold front came through and the humidity dropped. I filled my tank up and noticed my MPG is back up to 49 MPG, so the only thing that is different is the humidity. The cold & humidity does affect the MPG (approx 4 - 6 MPG).

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,

View 19 RepliesPrius (2010-12) Fuel :: Gas Mileage Went Way Down / AC On Nonstop With Higher Temps
I knew when I bought my car it wouldn't get optimum mpg as no car would with the many short trips I have to make every day but I have 5000 miles on it already and have averaged approx 46 with all the city and highway combined.
I took it into Toyota last week for the tire rotation and ever since it has been horrible. There were 120 miles on the tank and I refilled because I couldn't stand to see it staying around 39 on the computer. I have never seen that before. I checked the tired and they had brought them down to 32psi so I put then back to 40/38 and refilled.
Not noticing much of an improvement, sadly. Hovering at 40 mpg still. Weather has changed a lot. Temps much higher daily mid 80s to low 90s. This is my first summer with the car and yea the ac has been on nonstop with the higher temps.
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.
