Reply to comment by Lovv in 30 minutes of car preheating in sub-zero conditions produces as much particulate emissions as driving 97km in a gasoline car, or 20km in a diesel car “These findings do not suggest to stop preheating cars; instead, we could reduce the emissions by using similar methods that are in place for engine” by giuliomagnifico

I’m not personally concerned with interior temps. The practical benefit to having a preheated block, to me, would be three fold mostly:

  1. Lower fuel costs/emissions
  2. Lower engine wear
  3. Helping on the rare days I need to de-ice the windshield.

Even on days where it’s well below freezing and I need to drive for a decent distance I usually leave the heat off until the coolant reaches operating temp. I honestly don’t like the warm, dry air blowing on me when I’m already bundled up and comfortable. Even when the fam is in the car I do this. The kids are bundled up just like me and usually have their own blanket to keep them nice and cozy.

Heating up the interior is only something I’m concerned about on long trips. Eventually then cold will creep into my feet or I’ll want to take my gloves and scarf off to get more comfortable, but that’s always well after the coolant is up to temp anyway.

I bought electric block heaters for both of our vehicles, but then things worked out for us and we moved to a house with a garage. It never gets much colder than freezing, since it’s attached, so I haven’t felt the need to install them. There would obviously still be some benefit, but it’s not as pressing of a concern now. I’ll likely install them when I do the first coolant exchange. They install in the block drains, so it’s s bit of a job, too.

I have a garage but I do not use it as there is a lot of salt use where I live. Salt and water are much worse for your care than salt and ice.

Anywho thanks for the discussion.
