You can. The knock sensors will turn down the timing to prevent pinging so you won't cause any damage, but you'll loose power and performance.
Why buy a car with this kind of performance and use lower octane gas to save a few pennies?

I second the question by realmarty.

Stick with the premium . If you can afford a Lexus you can afford to buy premium gas for it.

these days 91 is more midgrade, with 85/87 as regular. i consider 93,94,95 as high-octane. whether you consider it a conspiracy or a use of better fuels, engines these days are built around higher octane. if you deviate, you are just running in a non-optimal out-of-spec situation. i can't speak to the "damage" aspect, but i personally think engines are tough -- especially japanese ones. karma might make you pay later if you don't pay now though (that is if you believe in that sort of thing).

Drive 12k/yr, assume 16 mpg (my 430 in mostly intown/suburban driving), $1.80 for 91 octane, $1.60 for 85, works out to $1350/yr for premium, $1200/yr for 85. Don't mean to sound arrogant, but if $150 means that much to you, you don't need a Lexus to begin with, no matter what kind of deal you got.
RealMarty correct, no damage will be done, but the performance won't be there when you put your foot down (and you may, of course, REALLY need it then). Actually, your mileage will likely be slightly lower with the lower octane. Which means the actual cost difference will be even less.
I think I'll go burn some gas AND rubber!!!!! Right now!!!!! What a spendthrift I am!!!!

hey...with all this gas talk, I was wondering why Orange county/LA only gets 92 oct gas and some other state gets 98 oct? I mean if gas stations here offer higher octane gas they would make even higher profits right.

Service stations make only a couple of pennies per gal no matter what octance they sell. Price competition is very stiff and the price to the station is set by the distributor. It is true that lots of money made at the corporate level but that's long way uphill from the pump.
As far as octane is concerned, numbers aren't necessarily comparable since there are different methods of defining octane, eg Octane Rating 91 = Research Octane Number 96. Those are the most common octane classification methods but there are others so pay attention to the fine print!!!!
