This morning it was about 5 degrees farenheit outside. I went to start the car and the first time I turned the key, I got power but no crank at all. There was no noise made at all. Second key turn starter cranked a little slow but actually turned the engine over.
I know my battery is a little old, had it since I got the car 3 years ago. Also the starter is the original one from what I can tell. I am running 10W30 oil.
Which is the most likely culpret, battery or starter? Is 10W30 too thick for this low of temperature?
I never have any problems except when it gets awful bitter cold.
