Prius (2010-12) Fuel :: Humidity Impacts On Mileage?
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).

If i am driving say for 15 mins on the highway at 65-75 mpg with a few brakes and accelerations in between due to other cars around, is it better to use the cruise control (i have adaptive cruise control on my prius v) and let the car figure out the throttle and braking or is it better to just drive by myself without using cruise control? i read about the different pulse-glide driving methods.

View 5 RepliesPrius C Fuel :: 2015 - Using Cruise Control Would Give Better MPG?
I just got a new 2015 Prius C Three and have been reading up as much as possible. I wanted to know if using cruise control would give me better MPG. If it's just a matter of 3/4 mpg difference, then I would use the cruise control to rest my feet. But if its a big difference, then I would avoid cruise control.
My daily commute from Germantown, MD to Alexandria Va and back is about 40 miles each way: total 80 miles. 90% of that highway on I-270 and I-495. I leave after morning rush hour and again drive back after evening rush hour.
Last couple of trips without cruise I have been getting around 50~52mpg.
Prius C Fuel :: Using Cruise Control To Maximize Regeneration?
Did use cruise control to maximize battery changing when coasting to a red light or slowing down for a speed zone? Just keep in mind your vehicle will slow down fairly rapidly with no brake lights- so I tend to to do this during those glorious moments when there are no cars behind mine. When you see an approaching red light (with cruise control on) just hold the cruise control switch down and the vehicle will automatically power the generators to max. In this way you will not lose any potential battery charge to the actual brake pads. Be advised also the generators will stop and the cruise will cancel automatically at 22mph which is usually slow enough to avoid engaging the brake pads until you are pretty much stopped. Just thought I would share a neat trick with fellow hypermillers. **Also note this may be a less effective charging method than long drawn out braking but is most effective for rapid slowdown situations like unanticipated red lights, speed zones or expressway off ramps ect. and requires some skill to do safely.

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...

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.

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.
