Question: Use of premium fuel

The RX calls for premium fuel, as do most Lexus vehicles now. I have been given conflicting advice from Lexus dealers about whether you can actually use lower octane fuel.

He said premium gas will generate premium performance, but unless you are planning on racing there was no need for premium fuel. The only thing he said was not to change the type of fuel you use. He further stated that EVERY car they delivered was filled with regular gas!

Your thoughts please.
