The 2002 Altima has defective catalytic converters. The media comes apart and gets sucked into the engine and destroys the rings. That is why so many folks complain about high oil usage. Nissan has abandoned owners and refused to do a recall. Buyer beware when dealing the this car company. My daughter purchased this junker and now can't afford the $4000 to fix it. Google "Altima engine failures" before you buy a Nissan. Who knows what other Nissan's might have wrong with them after 70,000 miles. Owners beware.
