Yes. Dense air = better combustion ratio; higher altitude = thinner air. The vehicle engine management computer will compensate for this but at the cost of slightly lower power and fuel mileage.

Yes. Be aware that cars in the Rocky Mountains for example are tuned to operate at the high elevations. Unleaded gas is also 85 octane, not 87. So if you drive a car say from Florida to Denver and cross the mountains for sure you will use more fuel and have a drop in performance.

What does 85 or 87 octane have to do with it ??
You are all contradicting yourself. read all the posts.
How can you burn more gas if it takes more air to burn more gas?? You all agreed there was less air at high altitude.
I have found that the engine tends to flood itself due to lack of air.
You have to apply the throttle carefully to prevent flooding, this definitely reduces power, and if you are carrying a load will cause you to down shift to keep the engine running
I would guess you may burn more gas due to higher rpm and low speed.
ust a thought.

Yes, elevation is affects mileage.
Higher up, you get less power due to less oxygen. Thus, you will probably be on the gas more to compensate.

I think that other guy had it right, but let me make sure. Less air equals more gas consumption.
