Like Mr Kite said, regular unleaded is 85 in Denver (think it's minus 2 for all gas in the mountains...). I'd love to hear the explaination for the octane range. |
The explanation is simple... at higher altitudes gas is harder to detonate because of the lack of oxygen... it acts as a octane boost if you will. So you can go for lower octane gas because it will not pre-detonate.
