Hello all. I just bought a rx330.It got about 3000 miles.Accordind to the spec, rx330 supposed to get better gas mileage than the rx300, between 20/26 (city/hiway). But the most i can get out of my RX330 in the city is 16 miles per gallon and 21 miles per gallon on the hightway.Is there anybody know something about this problem please let me know.Thanks.
