    Bertha (not her real name) had 1200 miles on her when I headed from Huntsville to Rock Hill, SC to visit my new granddaughter. I'll try to refrain from posting baby pics...(but they are both my baby!).

    The drive each way was 427 mixed interstate and back road miles. I tend to seek out back roads more often in the Prius Eco (adding the Two is redundant). Back road routes are sometimes a shorter distance than pure interstate but can take longer to drive. I figure it added another 30 minutes each way and eliminated 60 miles. Below are my findings.

    Drive to SC temps were mostly low 90s with AC on Eco/Auto set to 74f. Door to door showed 73.2 MPG. I was impressed. Drive home temps were 95 - 101f (taking a slightly different route to keep it interesting). Same AC settings as before except temp set lower to 72f. Averaged 71 MPG. Not as good as the trip there but the AC was working harder and a bit more interstate miles for the trip home.

    I've read all the stories here about dealers failing to properly inflate tire tires upon delivery (really!? that just can't be), so when I arrived home with barely 2000 miles on her, after cooling overnight, I finally decided to check the pressures. What? Dealers really are dumb as rocks. All inflated to 33 psi, and this is an Eco which recommends 39/36. Imagine the mileage I would have gotten with proper inflation. This is the same dealership that claims to have never before had a request to change the one-touch blinker from 3 to 5 and didn't know it was possible.

    They should be paying me.

    Would love to see a photo of that MPG with associated miles.

    Trip B was reset upon leaving SC. I ran some short errands today which added about 10 miles and subtracted some MPG from my above figures (very hot today and parked in full sun, but the AC worked like a champ!)

    Another view of Trip B for July 6, but notice July 4th! OK, I admit, there was a 3000 ft elevation drop involved that day.

    Here is my total mileage which has never been reset. Interestingly, the EV Driving Ratio is the same as trip B.

    Tyre Pressures - sometimes it can be the gauge(s) - I find they vary quite a lot. The other thing, in 2000 miles, they could have dropped a little. My Fiesta would drop about 2 PSI in 6-8 weeks, same in each tyre. They tyre place said that's normal, seeing each tyre is the same.

    When delivered, they would have had about 50 PSI, so the dealership would have dropped them. If their gauge or yours is wrong, that would give an apparent error. (I test-drove mine before the pressures were adjusted - it had just come off interstate transport truck - and the tyres hadn't been adjusted - it rides considerably smoother now that it has been prepared properly with correct pressures).

    Excellent results - but the average speed is "slow". I am driving today to Stuttgart and I am not taking any side roads, otherwise I will never get there....let's see what this baby does at 60MPH average ;)

    PS: when I leave the dealer, I always go immediately to the first gas station to check the tire pressure level - I have often found them, either with the pressure changed or less than what they should be... no comment....

    PS2: welcome granddaughter!

    I appreciate your urge to protect your car's anonymity. It shows your human decency.

    True that, but the Eco has Nitrogen filled tires, which in my experience, lose less pressure over time. Also, since all tires had the same low reading, the front tires would have had to have lost 6 lbs psi vs. the rears losing 4. Dealer fail.

    I used two different gauges. One was digital, the other analog. Both gave the same reading. I suppose both could have been wrong but...

    I've not been able to get compressed air at a gas station in the US in over 20 years. Some stations have coin operated air available, but more often than not it is out of service. What I should have done is check the pressures before leaving the lot.

    Thanks! She's a beaut. Three grand boys and now the girl. Does this mean I'm getting old? Don't answer that!

    I try to be thoughtful. Her butt may be ugly but I still love her.

    My previous car came with a "GOO + Compressor" - but I ordered the spare donut tyre instead - the compressor wouldn't fit any more, and I've still got it - it's a very capable compressor for tyres, with a fairly accurate built in gauge. But I've got a traditional gauge which seems to be accurate. We still get FREE air at all Petrol Stations.

    I only fill mine to about 78% Nitrogen ;).

    I'm thinking of adjusting mine to 5. I find that if I'm exiting from a Motorway or changing lanes, flick the blinker in one-touch mode, and don't cross the lane marker almost immediately, the Lane Departure Alert yells at me. 5 blinks would give me a little more time.

    Sorry - no, it's when you only partly push the indicator stalk (without pushing it far enough to lock it in to stay on), it only blinks either 3 or 5 times - designed for a lane change, rather than turning them on and then off again. That is on all models. With LDA appointed models, if it senses you don't have the indicators on when changing lanes (or crossing any line), it nags you with a couple of beeps.

    Really? Where is that documented? Never heard of that. And why would nitrogen be better?

    So where and how is somebody in the USA supposed to inflate their tires?
    If this is true nationwide, not only most US drivers drive cars with horrible mpgs but also drive with likely under inflated tires most of the time...?
    (Btw: to be honest I think most people worldwide do that, I hardly see anybody inflating tires at the gas stations in Munich. I wanted to buy myself instead a portable inflator to do that more often)

    I adjusts mine promptly at 5, 3 is not enough for the same reason you mention. And also because most Facebook drivers don't look very often in front of them and think you moved into the lane without ever using a blinker because they were too busy doing something else other than driving and looking the traffic ahead of their nose.
    Carista app+dongle did the job really well. :)

    Nitrogen may have benefits in some situations, eg racing, high speed etc. It may also maintain tyre pressures a little longer in a tyre. But the last report I saw said that it was of dubious economic benefit for normal motorists - as any benefits are balanced out by the cost of maintaining Nitrogen in the tyre. It is only slightly lighter, and more inert than air. I'll stick with the 78% Nitrogen in normal air.

    No, sorry I meant where is it written than the two Eco is delivered with nitrogen filled tires?
    And where can you find nitrogen tire filling stations?

    Here you get nitrogen from tyre service places. No idea about two Eco - we only get a limited 2 models here.

    Fortunately, I still find working air hoses at many gas stations. (Some are $1.50.) The attendant will usually turn on the machine for free. I still use the old "pencil style" tire gauge. Seems to be ok.

    I would much rather use a portable air compressor at home. Can anyone recommend a good one?

    "RoadNoise", I like your user name! And when I was doing my little 100 mile trip yesterday, that's all I heard! At highway speeds of 60, 65, 70, sometimes the noise becomes unbearable for me (depending on the road surface.)

    You got excellent gas mileage on your long trip. That's very encouraging. Congratulations on the beautiful little granddaughter.

    Thanks! I wish I could say the same for the Prius, but she is low maintenance (the car and the baby so far)!

    There is also an option for 7 blinks if desired.

    It is a dealer installed option and they said it was in there (but consider the source). I also have those green valve stem caps indicating nitrogen filled tires.

    I would say that many if not most cars on the road in the US have under-inflated tires. This is just my opinion based on my own human tendencies.

    When the time comes for new tires I will buy them at Costco, which uses nitrogen exclusively at no extra charge. When the dealer performs their scheduled maintenance (free up to 25,000 miles) I will insist that nitrogen be used when adjusting the pressures during rotation. The differences are minor but nitrogen molecules are larger than other gasses contained in ordinary air so less pressure is lost over time (I have observed this personally). Also nitrogen does not hold water vapor like air does so the interior of your wheels/tires are less subject to the corrosive effects of moisture. Again, the difference are so minor that I would never pay extra for it, but when free? You bet.

    Get a proper compressor with a holding tank. It doesn't have to be a large unit (mine has the "pancake" holding tank). Got it on sale at Harbor Freight.

    At one point during the trip my score was 98! Didn't last very long and probably won't occur again soon. I conscientiously drove the entire 800+ miles attempting to eke out every last mile I could, which was a bit exhausting. Will I do that again? Probably. I just can't help myself.
