Not really a problem, I'm just curious really. In the morning after the car (92 240) has sat all night, I'll get in it and without fail the car will start immediately. It almost seems like it starts after less than one revolution of the engine. This morning it was 18 degrees and it started instantly. However, after sitting all day at work (9 hours) it takes 5-7 revolutions of the engine to start.

What's the difference? Both starts are dead cold starts after a similar length of time and similar ambient temps.

I don't get it.

 

Some things we are just not meant to know: many factors affect starting behavior, 5-7 turns is not too bad...

 

is it sitting at a different angle when parked at work?

 

No. Other than location, there are no major differences between work and home.
