The Avalon and the ES350 use the exact same 2GR engine. Even the Avalon suggests premium for "enhanced performance". My guess would be that on the Lexus requiring premium fuel is not a big deal for most buyers where on the Toyota nameplate it may be. If you notice the Avalon is rated at 268 HP on reg and the Lexus is rated at 272 on premium.

See the comments above. Certainly, different engines can require different octane with the same compression ratio. Here, we're dealing with the same engine, with the added power coming from (probably) the added advance the knock sensor-controlled engine will allow with premium. The same power increase is also likely available to any 3.5 l car (Avalon, Camry, etc.).

My Owner’s Manual states that either regular or premium yields optimum engine performance (it is “either”; not just premium). Contrary to popular belief, the 268HP cap on the Avalon’s 2GR-FE won’t be increased by switching to premium fuel alone. That engine has to undergo serious mods in order to increase the horsepower output even by a few digets.

The 2GR-FE engine from the Avalon is the same thing as what is installed in the ES350 the slightly higher HP rating in the ES is from the requirement of premium fuel. Here is a shot of the owners manual from the '06 Avalo, showing my point: "for improved vehicle performance...."

Here’s another related case: One of my co-worker has an ’08 BMW X5, 4.8i.
How do you compare your co worker x5 with your avalon?
X5 feels a lot more specially doesn't it?
Of course you have to pay a price for that

Anyone with a 2008 Owner’s Manual for the Avalon sold in the U.S. can check page 414; It says nothing different from what I stated earlier.

One of the engines has a tweak that the other doesn’t. In very simple terms, horsepower depends on the thermal efficiency of the engine. Fuel type alone won’t increase this efficiency.

A 2GR - FE is a the same no matter what they put it into. They share all the same specs. Even on the spec sheet for the ES350 it reads:
"Ratings achieved using the required premium unleaded gasoline with an octane rating of 91 or higher. If premium fuel is not used, performance will decrease"
What does that tell you? Do you really think Toyota would tweak this engine for a lousy 4 HP? The "tweaked" version of this engine is the 2GR-FSE which is direct injected and used in the IS/GS and makes a little over 300HP.

I'm planning to buy or lease a Toyota Avalon Limited in the very future, which would feel luxury like the Lexus ES 350. The Lexus ES 350 has a power tilt and telescopic steering column and the Toyota Avalon does not have a power tilt and telescopic steering column. Before I buy or lease a Toyota Avalon Limited in the very future, I'm requesting the Toyota Avalon Limited to offer a power tilt and telescopic steering column for the late availability 2009 model year available at Toyota dealers by October, November, or December of this year 2008 so I can buy or lease a 2009 Toyota Avalon Limited with a power tilt and telescopic steering column and feel luxury like the Lexus ES 350 rather than having the 2009 Toyota Avalon Limited still offer a manual tilt and telescopic steering column. If the 2009 Toyota Avalon Limited comes with rain-sensing variable intermittent windshield wipers, heated and ventilated front seats, power rear sunshade, wood grain style leather wrapped steering wheel and shift knob, wood grain style interior, perforated leather seats, steering wheel mounted audio and climate controls, vehicle stability control with traction control and brake assist, 2-way driver's side memory systems, 8-way power driver's seat with power lumbar support, optitron meters with tachometer, speedometer, coolant temperature gauge, fuel gauge, and digital odometer with twin trip meters, smart key system with push button start, JBL synthesis AM/FM stereo with 6-disc in dash changer with hands free phone via bluetooth, optional dynamic laser cruise control, optional 8-way power passenger seat with power lumbar support, power windows with driver and passenger auto-touch up/down, power door locks with anti lockout feature, power moonroof, chrome outside door handles, etc., then the 2009 Toyota Avalon Limited should come with power tilt and telescopic steering column rather than a manual tilt and telescopic steering column.

If I wanted power tilt and telescope that badly, I would just spend the extra 25 grand and buy the Lexus! Why be uncomfortable while you are driving down the road.
