What have you been told from Mazda about turbo cooldown time ? The manual says 30 secs after hard driving(highway or quick accelerations).
I'm trying to convince my wife it's needed. It's her car and she thinks she has better things to do than to wait before she shuts the car off.
Thanks.

30 seconds is a decent wait time to allow the turbo to spin down. Longer is even better. Let her know that when coming to a stop shortly after driving and using the turbo that the turbo can still be spinning in excess of 20,000 rpm. If you just shut the CX-7 off right away you are taking away the oil supply and lubrication to these spinning parts. Everytime that is done it shortens the life of a turbocharger.
Is just a matter of getting in the habit of coming to a stop, put in park, and then allow to idle while you are turning off headlights, picking up purse and cell phone, coffee cup etc, take off seat belt, open door, and then shut off last thing. All of those little items will add up to more time than you would think.
Have you considered installing a turbo timer? This would allow you to go ahead and turn key off, get out, etc and engine can be programmed to continue to run for whatever time you set it for. Do not know who might make one that would be compatible with an immobilizer system though.

Actually, dealer told me nothing about this, but I read about it in the manual. It takes a little getting used to because it's a change in habit, but given what I've read so far it's worth it!
