So I don't drive a car very often, maybe once or twice a week. And I don't usually worry about that. When, and how often should I start the car? Should let it idle every few days if I don't drive it for a long time?
But now it's very cold outside -18 and I didn't drive my car for 5 days so I am worried if my battery will end up dead if i don't start it in next day or two if it continues to be so cold.
In other hand I don't know if it's actually more hurtful to the engine if I just start it for an idle for some minutes without actually driving it a few kilometers.
In other hand my car is Alfa Romeo 147 which have so many electronic parts on it and also ecu will reset if I take the battery out.
So should I just try to test my battery if it have enough power to start the car, and leave the car to idle maybe 15 min to get the oil through all the parts to get all those rubbers and sealants lubricated.
Or will I actually hurt my vehicle more if I am starting it more often on cold weather? Will ? actually make more damage to compression and damage compression rings?
