    Coming home today , 42 deg F in Elk Grove ,50 in Aurora.
    Wind E6MPH.
    32.0 miles , fcd = 72.6 x .943 = 68.5 MPG.

    litesong , there is a "bit" of truth in what your mechanic is saying. What I do is measure the width of the rotor , then decide
    if it needs to be replaced. If it ain't broke, don't fix it. If you really trust your mechanic, he may be right.
    Of course, what do I know ? I trust almost no one. But I have an honest and competent mechanic.
    On the Prius, the first brake job was at 118 K miles. We did replace two of the four rotors.

    Ha haaaa! Just the man I want to talk to. What were the reasons you replaced two, not all four, rotors? I suspect your rotors were in better or as good condition as our rear rotors on the 2016 manual Elantra, which just recently got changed, because my wife drives it, who is a safe, but not an efficient driver. Haven’t had any brake work yet on our 2013 automatic Elantra, which I drive, almost exclusively. Some time ago, my mechanic has said, it might be a while before the 2013 Elantra needs brake work. Personally, I think with easy careful driving, rotors won’t need changing when the pads do, except for any rusting……. Thank you for your answer, Edwin.

    Rotor change if below thickness spec, or warped and cannot be safely turned and smoothed out on a metal lathe. That's what I've heard.

    I replaced my own disc brake pads eons ago to get better "bite." I never got around to the rotors.

    There's nothing wrong with replacing just pads and postponing the rotors , as long as you're doing the labor yourself.
    That said , I don't do that stuff myself anymore , lol. When my trusted mechanic wanted to replace only two of
    the four rotors . he said the rears weren't badly worn ( scored ) and within the thickness tolerance.

    One HUGE advantage of doing it yourself is that you find out what wears out first ( for your particular driving style).

    Today 42 deg F in Naperville , 35 in Elk Grove. Headwind all the way , NE8.Also , someone spread molasses ( light rain ) all over the road
    while I was sleeping . making it very sticky. 35.1 miles , fcd = 56.7 x .943 = 53.5 MPG.
    If this wind continues ( and it sometimes does ) I'll have a good trip home.

    I've never needed to replace a rotor or drum in roughly 850K miles on the 4 cars I've owned. The Mazda, which did most of that total, got new pads and shoes a couple of times; the others never did.

    Got lost on the way to work. Not really , but I missed a turn and had to go south on an unfamiliar road ( Wolf ).
    Wasn't too bad , except timewise. 17.6 miles , fcd = 52.8 x .943 = 49.8 MPG.

    Oh, oh……Was driving near the southern border of King-Snohomish County bottomland & stopped at one of the Wildlife Recreation Areas. Heard from a birder that a rare area Whooper(pron.-hooper) Swan was in the region. So driving around some more, I spotted a number of parked vehicles. Approaching closer, I saw binoculars & a tripod-mounted spotting scope & knew I was about to strike paydirt. Stopping the Elantra & getting out, I was quickly invited to see the Whooper Swan, who had settled down with Trumpeter Swans. The really expensive Swarofski spotting scope gave a distant,turbulent, but good view of the Whooper! Similar to a black-billed Trumpeter, the Whooper has about half its bill covered in bright yellow. All the birders had a good time viewing & talking. The Whooper normally ranges from Japan, Korea, china, & russia, all the way to Britain & to Ireland. Of course, Lucky Binocular had to see the Whooper, too. Even tho 17 power was much lower than the 50 or 60 power of the Swarofski, the smaller lens of Lucky, really helped to cut the air turbulence & showed the Whooper fairly well. It is only the 2nd time the Whooper had been seen in Washington state. I wonder if it could have flown high enough to catch part of the jet stream from russia? I’ll have to read up on the Whooper Swan.

    PS….Generally, the Whooper flies considerably below the jet stream, at about 1000-2000 meters, to take advantage of many fields to feed. However, at least one Whooper was known to fly as high as 26,000 feet!

    I appreciate you and Edwin taking the time to record stats and posting. I don't know how you guys do it, what with life going on and all... :D Your passengers (when there are some) must be very understanding. It would be nice if your Tesla would provide you with a means to extract all that info automatically in a format of your choice. Maybe someday. Just ask Elon.

    Edit: My wife and I run (different!) trackers on our phones to capture business miles when there are some. Time, date, locations, distance are all there. So a merge of this kind of info along with your choice of notations and something that's already captured by the Tesla back end would be nice...

    Yes, it tells me psi of each tire and goes orange if too low and I keep a battery operated pump in the car which I can set to whatever pressure I want :cool:
