I traded my 01 RX 300 for an 05 RX 330 and I pick it up tomorrow (Sat.) My question for you guy`s is;I checked the service records and it was maintained @ the Lexus dealer where she purchased it.And it turned out to be around 5k oil changes,my question is do you all think I should just use Pennzoil conventional and 5k intervals,or go Synthetic? BTW it has 59k on it.I`m undecided because this motor is not supposed to be a sludger,and because of all the great comments on here re: conventional oil these day`s.
