It's currently with me in the mountains where it gets very cold, is there any chance of me damaging it by starting it? I started it 3 days ago and let it run for like 15 mins, but haven't since. It's currently covered in frost. If you need more information in order to help me answer the question please just ask, I'm only just starting to learn about the whole science of it, so I don't know a whole lot. SO GRATEFUL for any information I could get. Thanks heaps!
How cold is very cold? The outside temperature when you go to start it is key. But in general, unless you are more than twenty or thirty degrees F below zero, I would say the answer is "no damage"... provided you have used an engine oil and an antifreeze mix that is appropriate for your climate. Your owner's manual should contain the information you need.
Your battery must be in top shape as well, not to prevent damage, but to achieve proper cranking speeds.
