CGSB

in Canada. Improved gasoline specifications have been

developed by the American Automobile Manufacturers

Association (AAMA) for better vehicle performance

octane or higher and you

hear heavy knocking, your engine needs service. But

don’t worry

you hear a little pinging noise when

you’re accelerating or driving up a hill. That’s normal,

you have a problem.
