Little bit better this tank. had another 80 or so miles to empty, but I like getting gas before it get below an eighth of tank. 575 miles, 9.483 gallons, 60.64 mpg calculated (64.8 displayed).
Yes, weather was a factor... I did have a 70 mpg day (50 miles) since it was about 40 in the am and 50 on the way home. I've also gotten better w/ pulse and glide. Letting off the gas and going into ev or just high mpg w/ ice on. I'm also taking the back roads to and from work. Distance is the same. With the lower speed, I get better mileage, but it takes another 10 minutes or so each way.
Hmmm... why doesn't my fuelly sig image update. I've got 4 fillups @ 59.1, but it hasn't updated here. I must be doing something wrong lol.
It's been a couple of days, and when you click the image, you get the correct image/data, so I'm almost thinking it's a caching issue... It usually "fixes" itself after several days...
Clicking takes you to the Fuelly page. I believe PC uses a CDN (content delivery network) for caching because I have seen some CDN errors when PriusChat is down.
570 miles, 9.849 gallons, 57.9 mpg calculated, 62.6 displayed. Some mixed weather temperature wise... but I'm still getting around the EPA numbers in winter, so it's all good.
Having driven my Gen4 for about 4000 miles, my numbers have stabilized pretty well. My situation: I live in Singapore, where it's never cold. At all. So low temp starts and heating are a non-issue, but air conditioning is 100% on (in Eco mode). I drive for Grab, the local replacement for Uber. So I see a lot of low-speed roads and parking lots, interspersed with larger roads and some highway runs. Mixed urban/suburban. Best sustained fuel use: 3.6L/100km, 65mpg. (Nighttime run, lots of 35mph roads) Worst sustained fuel use: 4.6L/100km, 51mpg. (Sunny afternoon and lots of stop n go. Before window tinting) Average: 4.1L/100km, 57mpg. In hot weather, keeping cool is 20% of my fuel use. Sigh. All numbers based on calculated usage, which is about 5% higher than the dashboard number.
I just go by what the Prius says on the dash. I am not too into the details of each fill up. My Prius in the trip computer says 49.5 MPG from the very first mile of the car. On my current tank I am averaging 50.5 MPG which is a mix of city and highway miles. I focus mostly on how many miles are on the trip computer for the tank shooting for high 500's for each tank and wanting the fill up to be just shy of 10 gallons. Winter driving conditions right now and 50-52 MPG on a tank for me is pretty good considering my use of heat at 70-72F.
Sorry. All the other figures in that posting were mpg and 50.0 mpg would be a reasonable average for a tank in the given situation. I just realized they are both the same thing. 50 mpg x 10 gal = 500 mile tank.
We are all professionals here. Most of us low ball our mileage. It's more like 55-56MPG. 550+ on a tank. When you start seeing 60+ MPG posts in the winter, you can call BS. I have not seen any of those claims on a non plugin Prius.
Actually 60+ is possible on Gen 4 in warmer climates. A few in California have seen those averages. I think 70 is stretching it, though. EDIT: Look no further than the first post in this thread. I believe @krmcg averaged in the low 60s for quite a while.
That is what is great about gen 4 Prius. A bright full color display showing mileage so people can take photos of their mileage achievement at the pump.
We've had a mild winter so far here in New England, so I've been able to stay above the EPA mpg rating so far... (calculated, not the dash). I've been driving back roads to work instead of the highway, so that further inflates my mileage... AND the dash reads 5% over the hand calculated mpg... SO... the devil is in the details... and there's always more to the story. Starting a new job in a couple of weeks, and It'll be colder in Feburary AND a highway only commute, so my numbers are going to take a big dump and come back to earth I estimate that I'll be down in the low 50's...
My calculated seems to be pretty much consistent with EPA for the winter months, which is no small feat. I don't drive every day, but on the days I do I've been generally pleased with what I've seen. Weather has been decent this winter, it's not Florida but it hasn't been bitter cold like past years. Knowing the cars behavior from watching the Scangauge, I don't run heat until I get on highway so ICE doesn't run unnecessarily.
Warm weather driver here. I have not gotten less than 600 miles from a Gen4 tank, and that includes running the aircon 100% of the time. Hit 65mpg over a four-hour span at night, when aircon use is minimal. And this is while working as a driver for the local Uber-analogue. So my routes were "whatever Google Maps says is the fastest". On a round trip with a controllable path I have no trouble seeing someone getting 70mpg. One possibility is that I have the Eco tires? I'm not in the US, so the trim levels aren't equivalent. Tires become kind of a big deal at these efficiency levels.
