87 is just fine for these cars. Do not need to waste $$$ on premium IMO.
Our business development guy is driving ES for work, he has close to 200,000miles on his car driving on 87 ONLY. No problems!!! I've asked people around and tried comparing premium vs regular myself and honestly i dont see any difference.

Are you serious??? You push rpms to the red line daily, your motor blows and you blame it on regular gas? Are you freaking serious? Genius . Wow.
It is dressed up daily beater, also known as toyota camry. Premium cars are: ferrari, maseratti, aston martin etc.
These toyotas are good daily beaters. Dressed up middle class "luxury". They are reliable and last long time .. when you dont red line them on daily basis. lol.
Wow. Is this guy for real???

Too many variables....driver, load, ambient temperature/pressure, engine condition, etc....
What works for one owner might not work for another owner.
If you are looking for ways to save a few dollars and not knowledgeable about drivetrain, there are other better ways to save money....

Myth: Premium gas is better for your car.
Reality: Most vehicles run just fine on regular-grade (87 octane) fuel. Using premium in these cars won't hurt, but it won't improve performance, either. A higher-octane number simply means that the fuel is less prone to pre-ignition problems, so it's often specified for hotter running, high-compression engines. So if your car is designed for 87-octane fuel, don't waste money on premium and if you car recommends (not requires) premium, you can usually get away with using regular. Some cars truly require premium, meaning you're stuck paying extra.

For two reasons, the first applies to the 3rd generation as well; this engine is high compression at 10.5:1. So the car will have improved performance from running higher octane fuel.
The second reason, which applies only to the 4th gen, is because it has DBW. The transmission will behave much better with high octane fuel. Lexus themselves have said to run high octane fuel in a TSB regarding shift quality.

Transmission cares about gas? this is a new one to me...
I 've switched back and forth and there is no difference that i can feel/see in performance.
If regular was bad in nay way there would be a big red sticker in front of your face saying - PREMIUM ONLY.
What do you mean by improved performance? It is a daily driver designed to get me from A to B. All i care about is miles per gallon.
I am not drag racing fighting for extra seconds on a quarter mile strip... come on, we are talking rebadged toyota camry here.

Umm, actually the ES will benefit. Especially the 4th generation.

If we are talking about just a "rebadged camry" then why don't you go out and buy a Camry.
I'm sorry, I don't have the patience to deal with ignorance.
It's your car do what you like, but do not spread false information that's all I ask. This is forum is to help others, if you don't know what you are talking about I kindly ask you don't write it or at least put a disclaimer.
The last thing I will post in this thread is what the manual states. You can interpret it anyway you want.
Octane rating
Select premium unleaded gasoline with an Octane Rating
of 91 (Research Octane Number 96) or higher for optimum
engine performance. However, if such premium type
cannot be obtained, you may temporarily use unleaded
gasoline with an Octane Rating as low as 87 (Research
Octane Number 91).
Use of unleaded fuel with an Octane Rating or Research
Octane Number lower than stated above will cause persistent
heavy knocking. If it is severe, this will lead to engine damage.

It's not the transmission that cares about the gas, it's the ECU. It will pull timing to compensate for low octane fuel. What's so hard to understand...

Why does Toyota Camry have this same engine and not require premium gas?
The 1MZ-FE is a 3.0 L (2994 cc) engine. Bore is 87.5 mm and stroke is 83 mm. Output is 168–190 hp @ 5200–5400 rpm with.....
Applications:
1994–2006 Toyota Camry (V6)
1994–2003 Lexus ES 300 & Toyota Windom (Japanese domestic market)
1996–2004 Toyota Avalon & 2000 Toyota Pronard (Avalon for Japanese domestic market)

"In the old days, engines could not adjust to fuels with varying octane ratings. Use the wrong fuel and the engine would knock or "ping" audibly because the gas exploded prematurely. This knocking damaged internal engine components over time.
Today, engine control systems can compensate for low octane by monitoring knock activity and adjusting ignition advance to avoid knocking. This sophisticated electronic capability effectively tunes the engine on the fly and gives drivers more flexibility in the grade of fuels that they can safely use.
Compared to premium gasoline, lower-octane fuels don't allow the engine to run as much ignition advance during situations calling for rapid acceleration. More ignition advance allows the engine to make more power, and accelerate more quickly, during these conditions. Since the engine doesn't make quite as much power with lower-octane fuels, this translates into slower acceleration in cars for which premium fuel is recommended. The performance loss is especially noticeable in turbocharged gasoline engines, which have become increasingly popular in recent years.
The performance loss, however, is something you will only notice if you have a heavy foot and accelerate rapidly from a dead stop or while changing lanes at highway speeds. But if you accelerate moderately, the loss of power is barely noticeable, regardless of whether you use premium or regular-grade fuel."
