All very interesting. Thanks guys. I guess ultimately the answer is to drive it the long way and get closer to that 180 mark. That's not also that practical, but I will try to be more disciplined about it.

So, I know that idling in the driveway for a few minutes (3-5 was suggested) can also be bad. What is worse, letting it idle for 5 minutes so I can eventually get it up closer to 180 on a more consistent basis, or only getting it up to 150 like I am now?

Is this 150 situation really bad for my car?

Thanks again.
