Since this is the most recent oil thread. And instead of creating a new one. Does anyone know is a 00' STS has the oil life extender in it (knows you drive highway so it will increase oil changes past the usual)? I havent taken numbers and figured it out. But compared to my dads 97' I seem to last longer (much more highway driving).
