When I bought mine yesterday I filled up with Regular, mainly just because I was strapped for cash after I left the dealership, but I will probably be filling up with Premium from now on.
Oh and I have a 1999 ES300.

I calculate my mileage after each fill up on ALL my vehicles and log it.
I use 87 octane on my '98 and my mothers '97, and the last check I got 23.2 mpg
with 90% city and 10% hwy driving on 1 tank. 2 short highway runs. I'm NEVER on the hwy.

Using premium gas in an engine designed to run on regular doesn't improve performance.
http://en.wikipedia.org/wiki/Octane_rating
to further that, the recommended fuel BY LEXUS is 87 octane, and 91 for "High performance"
High Performance meaning if you're putting added strain on your engine like racing, or driving
through mountainous terrain, you would use premium. The average flat land commute.....worthless.

A common understanding that may apply in only limited circumstances amongst petrol consumers is that adding a higher octane fuel to a vehicle's engine will increase its performance and/or lessen its fuel consumption; this may be false under most conditions — while engines perform best when using fuel with the octane rating for which they were designed and any increase in performance by using a fuel with a different octane rating is minimal or even imaginary,

these cars where built to run off premium gas,
whether or not u feel the difference in performance or not, the person who uses 87 octane will have a shorter engine life over time
87 & 89 octane is not clean enough
91 octane? I havent seen that in NY or NJ since like the 80's where do you guys live?
93 or 94 is the way to go

In a pinch, I'll probably visit a Shell. First time I filled up I went to Arco...

93 For Me
While the handbook for my 98 ES 300 says it is Ok to use 87 grade, the last time I tried to go that route I got nothing but trouble--knocking, lurching, choking, you name it. Then when I got it to the shop, the repairman said the cheap grade fuel had fouled the plugs, and I ended up replacing them (not cheap).
Ever since then I've used 93 grade, mostly Hess, sometimes Shell, always $$$$$, but worth it. Engine has 204,000 miles one it, fixed two valves in December, getting about 25 MPG.
Love My Lexus!

Geez,maybe you should have re-set the ecm after doing it? Did you get bad gas from joe`s gas & Deli or something?

Here is a page taken out of the 2007 ES Owners Manual which is exactly the same for '02 thru '06 ES's. It shows that regular grade fuel is completely accepted. You guys/gals that insist that premium fuel is the answer.....than keep dreaming, while I pocket the extra cash and spend it on things that give me much more satisfaction!
Thats kind of a no brainer.

I just tried using premium for the first time in my 97' a few days ago because the manual clearly doesn't even go as far as to reccomend premium, just says "for improved performance". So, I said **** it, it's all over 4 a gallon anyway, and I have to say it ran and idled ever so slightly smoother, and my mileage was better than my yearly average by over 2 mpg. I'm still not convinced though, more testing is in order...... This was 93 octane by the way, and I did not reset the ecu.

you are a fin moron
manual says to use 91 for people at sea level, unless its not available!!!!!!!!!!!!!!!!!!!!!! you're messing up your engine eveytime, and the ECU is correcting for it, but the damage still occurs everytime it has to get you going or on heavy load
that damage is horrible. who knows how long your engine will last
lexus parts/service dept makes fun of their own customers and their very uninformed nature when it comes to cars and maintenace. Its says use 91. it says use 91. you bought a lexus. still, you MAKE UP YOUR OWN SCIENCE that says you can use 87 based on the "what-the-heck, why not use 87" theory and mention saving money. WOW
freedom to express myself freedom to feel freedom to be myself like you morons
