Some perspective Chevy Volt buyers got a little nervous last week after the vehicle line director, Tony Posawatz state that the Chevy Volt engine is calibrated to run on premium gasoline. Now that the furor has settled down some more accurate descriptions of the Chevy Volt engine is starting to emerge.
According to GM Powertrain spokesman, Tom Read, the Chevy Volt’s 1.4 liter engine will not be damage from using regular gas, as it, like pretty much every other modern car, has a knock sensor. While the engine is calibrated for premiuim gas, the knock sensor will adjust to regular gas by altering the spark advance to prevent engine damage.
Although premium gas might still be preferable anyways since most Chevy Volt drivers won’t be using the Chevy Volt range extending engine very often, which means that the longer shelf life of premium gas might make it generally preferable.
