You use a gallon of fuel for every 5 hours of idling in the xD. So 2-3 minutes of idling a day will use up about 0.2gal, or at $3/gal - 60 cents worth of gas.

 

Well that and that i drive my car at least 2 times a day usually more so that multiplied by 2 or 3 even. Which ends up being about half a gallon thats a decent amount of fuel.

 

Can I answer the first post with an extremely easy answer. Most vehicle you are familiar with have an anolog (needle) for the temperature guage. The Scion xD and Toyota Yaris models do not, therefore they have a light. Green when cold, Red when overheating.

 

Not sure if this matters to anyone or not, but this has been my experience so far (keeping in mind I just got my car Friday...lol!)

This morning when I got up to go to work at dark o'clock, it was 15 degrees out. I started the car 4 minutes before I wanted to leave for work -- when I got into the car, the green/cold light was still on and remained on for approx 2 more minutes so 5-6 minutes total. The past couple of days when it was closer to 30 degrees out, the light stayed on for just 2-3 minutes.

I understand the premise of not letting the car idle/warm up unnecessarily, but on the other hand, when it's below 30 degrees out, I'm assuming it;s a good idea to let it warm up a few minutes. Can hardly wait (j/k) till it's below zero out there!!!
