What kind of gas does the 2005 Toyota Avalon take?

The 2005 Toyota Avalon can run on regular, 87-octane, fuel, but the specifications and fuel-economy ratings are based on 91 octane. In most cases, using higher octane gasoline than Your owner's manual recommends offers no benefit. It won't make Your car perform better, go faster, get better mileage, or run cleaner.How You drive can significantly affect Your fuel economy. The harder You accelerate, the more fuel You use. Unnecessary braking wastes the fuel You used to get up to speed. Drive smoothly and anticipate the movement of traffic. Once up to speed, maintain a steady pace. Smooth acceleration, cornering, and braking also extend the life of the engine, transmission, brakes, and tires.
