Regular gasoline at almost all higher elevations is 86 octane. Manufacturers of most new cars — including our 2004 Lexus ES 330 — recommend regular gas, only 87 octane. I haven't found any clear explanation of why gasoline distributors sell regular at 86 here, and at 87 at sea level. Also, I'd like confirmation that my car will perform properly with 86 octane at 5000 feet — our altitude here in Albuquerque.
