400h octane for gas

What octane of gas do you fill inside your 400h? I fill it up with premium just because it is recommended but there is no sticker saying premium only like my LS430. Has anyone heard anything from their dealer about this? Also what octane do you fill and what gas mileage do you recieve. I fill premium and get amazing gas mileage. I know the difference because when i left the dealer, i had a full tank of normal gas (dealer supplied). That ran about 360 miles. I filled it up with premium and i have half a tank with the odometer on 600 (240 for half a tank). But then again i have a FWD so im not sure about the immediate difference between mine and an AWD

Thanks

87 min / 91+ recommended

From what I recall, the manual states 87 as the minimum but recommends premium (91 or higher). I'd be interested in seeing what the recommended octane is for the HiHy.

I can state that premium gets better mileage. Its worth the added cost in my opinion I'll post a comparison as soon as i get more mileage on the vehicle
