Re: Recommended fuel

Q. While I was in Colorado last summer I noticed that they have a lower octane gas Ė 85 than the regular gas in California. I will be in Colorado for the summer again this year, and I am wondering if I can put the lower octane in my truck and not have to worry about it. Can I safely use this gas, thereby saving a few cents per gallon? Or should I continue to use what I normally use, which is 87 octane?
A. Go for the lower octane, cheaper stuff when youíre up at the altitudes where they sell it.
In most of the county, regular octane is 87, mid-grade is 89, and premium is 91 to 93 octane. In the higher-elevation communities in the mountain states of the West, youíll find that 85 is regular, mid-grade is 87 and although youíll see 91 octane, you may never encounter the 93-octane gas you find elsewhere. At higher altitudes (above 4,000 feet or so) engines need less octane to operate properly.
When you drop back to a lower grade, you may experience slightly reduced power on hills. Some claim that happens, others say thatís merely the perception of the flatlanders, who arenít accustomed to the kinds of hills we have here in the mountains. In any case, if you feel that youíre getting enough pickup on the entrance ramps and interstates with the 85-octane fuel, you can feel very comfortable using it without concern that youíre doing something bad to your truck.
When you leave the high country and get to 4,000 feet or lower, you may still have some 85-octane fuel in your tank. Donít worry about it. Just fill íer up with the 87-octane gas when you can. The blend of the two will serve you just fine.
