neumannu47 Posted August 10, 2007 Share Posted August 10, 2007 My 2000 RX300 has a multi-disk CD player. It is a pain to change CDs, and it is totally unsafe to do while driving. It is my understanding that a single-play CD is not available for this model. Is that correct? Also, does this model and year require premium gas? We are using premium, and our mileage has increased four miles per gallon. And the knocking has gone away. I have always heard that octane ratings were somewhat of a hoax, but my experience has been otherwise. Quote Link to comment Share on other sites More sharing options...
