Definitely friction is your ever friend or foe. Cant go about laws of physics but as stated in a normal driving scenario nothing to worry about OP.
Unless you do rev your car 6 to 7k rpm on a regular constant basis then that is a big concern for easy wear and tear!

Dry start, how often do you need to start your car? You don't, you just need a battery tender. If you're storing your car for 6 or more months there are a few things you would need, are you?

this has got to be one of the worst recommendations... :shakes head:

my recommendation is you change to synthetic oil and just start the car when you know you will drive it more then 10miles.
and keep the battery on a battery manager in the days/weeks you dont drive the car.

During my Z's hibernation last winter I started her up about once a month. Everything worked out fine. Started every time and battery never died.

Battery Tender or other such float charger. Starting the car periodically isn't helpful and probably is counterproductive.

Agreed. Paying someone to start your car. Almost certainly does more harm than good. Not necessary for battery maintenance, and unless the engine comes up to normal operating oil temp, all it will do is facilitate condensation of water in the engine without the time or temps necessary to boil it off. Bad idea.

Every time you start your car there is wear. When you start your car, regardless of what type of oil you use, you only have boundary lubrication i.e. metal-to-metal contact between the bearings and the journals. The very thin oil before start up isn't enough to prevent this wear, even though it's very, very minimal but it's still wear. Once the engine is started and pressure has built up in the first few seconds, you have hydrodynamic lubrication i.e. no metal-to-metal contact between the journals and bearings. So, you decide how often you want to start your car.

i just scared that if leave more than 2-3 days-week-2 week, the oil will mostly go down to bottom(even that thin oil have enough time to go away) while of you start every day, the more oil still stick to cylinder. yet reduce the risk of metal-to-metal

The new car at dealer ship dry start for sometimes, but 4-5 dry start then it is picked up is acceptable. On my case, 5 months x 3 times a months=15 times. plus in the next 1-2 years :roflpuke2: cause i keep car as a collection

PS: is there any else reason for battery tender rather than it dead ? i means battery is only 150$ and i dont mind replace it every year. Z is a very good looking car and it deserve good treatment :roflpuke2:

If you are really afraid, just do what this guy did with his s2000

Fixed it for you (20-30 minutes is all it takes). Now do you see why starting it every day is a bit silly?

But it's your car - if it makes you feel better, start it every day...

Reinstall the spark plugs (or an old set of used plugs for storage) without torquing them completely, and crank the motor briefly with the plugs in and the positive lead to the distributor or the coil wire removed. (Don't let the engine fire.) This will coat the combustion chamber and cylinder walls with a protective layer of oil. Don't restart the car until spring. You will need to change the spark plugs back to your good ones or buy new ones in the spring because of the oil that fouled them with the protective layer.

There are many other storage recommendations all with pros and cons and different levels of obsession. Search the internet and you will find a lot.
