Answer 1

Regular gas is the recommend grade of gasoline for the 2000 Corolla. You can use a higher grade, if regular is not availalbe. No damage or performance changes will be present. In some cases, due to the natural accumulation of deposits in the engine, some high mileage examples will exhibit less engine "pinging" under heavier loads or even experience a slight increase in fuel economy.
