All of the V6 engines in Toyota cars are rated for regular gas. They use the exact same engine as a Lexus and they all have a 10.8:1 compression ratio. So who knows why Lexus rates theirs for premium gas. If regular is good for a Toyota then it would be good for a Lexus. I don't buy this idea of I can feel it run better with premium gas.Put someone in Lexus with premium gas and then one with regular gas and then wouldn't be able to tell the differance.

I just bought a used 08 RX350 and when I run the air conditioner for awhile I get a squeaking noise around the radio area. After it warms back up the squeak goes away. Has anyone had a problem like this?
