There's been a lot discussion about this among ES350 owners. In the ES premium is recommended, IMO, to achieve the advertised 272 hp.

The same engine is used in Camry, Avalon, RAV4, Highlander, Sienna and Venza with 268-270 hp with regular recommended. In this case I think it's up to the owner. In high performance (DI, etc.) engines premium is a must.

I've read that the mid-grade is actually just a mix of the regular and premium... so sometimes it could be mainly regular grade, or sometimes mainly premium. Bottom line - it's not consistant.

I was using mid-grade on my '99 LS for a while since the previous owner did but after I read that information (more than one source) I stick to premium (which is recommended by Lexus for this model). I think since I've done the change, the mileage has increased a little, which makes the price difference a wash.

For a while, Shell here, was also offering a ultra-premium fuel at the local gas station which was rated at 100 octane. I never tested it, but I wonder how much difference it would have made.
So I stick to regular on the ES (it's not a race car by all means), and regular is well, by the looks of it premium to you guys?
Your octane rating is different from ours.

It's good to see that they are being informative on the question of which octane to use. I think Infiniti is doing the same thing on some of their new models.

the way we have the octane calculated is different from the one in Australia... it is comparable.... and also US has strict emissions regulations which also hinders the higher octane number... here in IN i have 93/94..
