Do I need to adjust my car for high altitude?
Do I need to adjust my car for high altitude? In higher altitudes, the levels of oxygen in the air are lower. For this reason, your engine idling needs to be raised. You'll find how to do it in the car's instruction manual. Alternatively, seek the advice and help of a professional car mechanic.
At what altitude do you need oxygen?
For best protection, you are encouraged to use supplemental oxygen above 10,000 feet MSL. At night, because vision is particularly sensitive to diminished oxygen, a prudent rule is to use supplemental oxygen when flying above 6,000 feet MSL. So, when you fly at high altitudes, supplemental oxygen is the only solution.
