Ok, this may be a dumb question, and I'm sure I will get flamed for asking it, but still, it's a question that keeps coming to my mind and I'm not 100% certain on.
I live in a very hot, sunny place. (Phoenix, AZ.) Lord only knows what the temperature inside a sealed, parked vehicle can get to in the summer. I bet it's near 200, if not over.
I have 2 full 5 gallon gas cans mounted on my rear bumper. I frequently park the jeep in a concrete, unshaded lot all day. I have been wondering if perhaps there is any risk of some spontaneous combustion here, with those gas cans baking in the sun all afternoon?
I have never heard of such an accident, but still... maybe I should empty out the cans until I need them for trail use?
Am I just being silly here, or is there a real risk?
