      Reposted because I originally calculated the time as 5x too fast.

      Measured using an Arduino temperature sensor placed in front of the vent, plotted in OpenOffice. I idled longer than normal to collect more data.

      * Idled for 6 minutes to warm up engine and clear snow
      * Drove 5.5 minutes to store (1.4 miles/2.3 km)
      * Shopped for 18 minutes (vent off)
      * Idled for 7.5 minutes (ate a breakfast sandwich)
      * Drove 5 minutes home
      * 3.5 minutes with car off and vents still on high

      Vent was set to highest temperature, max speed. The dips while driving occurred at stop lights. Not sure about the noise while in the store.

      Next time I suppose I should drive the van longer to determine the max temperature.

      Any idea what might cause the temp to increase in short bursts during the downward trend when it’s off?

      inb4 everyone comments on how modern cars dont need the engine to be warmed up

      but you can actually see from your own data that the engine was still warm after shopping as the temperature slope is nearly infinity. so like realistically the only reasons to eat a sandwich alone in a parking lot is

      1) was starving, couldnt wait 10 minutes to drive home
      2) avoiding home situation

      Your minivan probably is not even the sort that benefits from being warmed up.

      I guess I’m sensitive because I live in a metro area with extreme air quality issues, but hell stop idling vehicles. It’s so 1970s. To me, it looks like having a glass of wine and smoking while pregnant. Soooooo old fashion, like times have changed, and that isn’t adequately responsible anymore.

      I want to see highway speed temps. Then a full throttle acceleration from stop back up to highway speeds.
      The heat output after a full throttle session is always a noticeable increase.

      Lol. 10 min idling, 5 min driving. Just walk next time.

      Btw idling is illegal in Germany. You drive right away.

      These discussions around idling and warming up a car are always funny to me…

      I certainly understand a newer fuel injected car really only needs a few moments to get the oil circulated and fuel ratio set.

      However….

      I sure as shit turn the shower on and let it get warm before I hop in.

      I remote start my car to get the cabin warm before I get in.

      I was always wondering how the heating in a car works. Good to know! Especially that the temperature seems to plateau while idling.

      I always wonder if the heat would go up faster if I rev my car while in neutral. Seems like it probably would!

      Everyone in here complaining about the idling actually live in a climate that plunges below zero to negative double digit temps?

      Why does it seem like it cooled off so much faster the second time it was off?

      Seeing this makes me appreciate my EV. In negative temps I timed how long it takes to get warm air out of the vents: 1 minute 15 seconds.
      In similar temps in my previous ice vehicle, I would let it idle for 5 minutes and would only get warm air in the last 5 minutes of my 19 minute commute.
