Dry start ? how often do you need to start your car

IDZRVIT

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 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

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...

INJECT OIL: If you really want to go to great lengths and are truly obsessed, take a lesson from motorcyclists: Remove the spark plugs and inject/spray a little oil into the cylinders. 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.
