When we bought our first Lexus a few months ago, the sales person and the service manager both told us to change the oil every 5,000 miles. This is a little different than what we do with our other non-Lexus vehicles, but they must have a reason for it. I will take their advice. Just talk to anyone who has owned a Lexus for sometime they have absolutely nothing but positive things to say about the vehicle and their dealership.
