Elevation in Butte MT is 5400'. Consequently the refineries in Montana produce a slightly lower octane (NoLead is 85.5) because the higher the elevation the lower the octane needs to be. For instance if your vehicle's manual says it requires 86 or 87 octane, 85.5 octane NoLead will be perfectly fine. http://www.summitdaily.com/article/20050812/NOTES/50812008
