My mother has an rx-300, shes had it for 2 -2.5 years now and it seems to be running like a champ, i always hound her on getting the oil changed and checking fluids and such so she takes it to the dealership to get everything done every 3000 miles even though the dealership tells her she doesnt need to do it every 3k
what exactly is this sludge problem etc? little more info on what causes these massive f'ups?
