You guessed right it is the US and we do have 3 different grades. The two salesmen I asked (at the different dealers) didn't agree. So which is it? Anyone know?

First, let me say hi as I'm new to these boards. We are thinking of buying a 2003 RX300 and would like to know if we can use regular gas or do we need to use premium. We've received two different answers from two different dealers so we aren't sure. I know all you Lexus owners will have the correct answer. Thanks.
