Sorry, should've done a quick search.
I read the manual, and can't find where it says this. The only things about cold starting I could find were "Do not race a cold engine" and under the "How to save fuel section pg 215", it says
Could you please give me a reference to where it says its BAD for new car engines? Still unsure whether I should leave the car for a while if it doesn't damage it..
Cheers.
I had to pull out my manual and search this just for you...
Go to Page 201. "Engine should be warmed up by driving, not in idle..." continue reading that section in the manual.
I only heard its "bad" which by that I meant you are adding unnecessary wear and tear to an engine that does not require 15seconds+ warm up time. Imagine you leave your car to warm up each morning for lets say 3minutes, and over its life that add's up. Its best to leave it for few seconds, and drive very easy to warm it up, which is even recommend in the manual.
Your adding unnecessary wear and tear because in idle the oils don't move around properly while warming up in idle, so gradually warming up by driving lubricates the engine properly.
The MAX I would do in an Aurion is 1 minute in freezing Melbourne winters where it can be 5 degrees on some mornings.
My dad is old school and thinks I need to warm up my car like his old 92 carby engine
Hope this helps.
even in my twin turbo i wouldn't let it sit idle... i'd slowly drive it off and not rev it past 3thou.
different chains of thought i guess!?
