ty for your nice reply. im wondering what the manual recommends. in the old days when there were carbs and no computers i would run almost everything on premium. now with the afore mentioned i only use what the manual recommends. hope its regular but i fear you may be correct.

Manuel recommends 91 octane. BUT it will run on 87, with a minimal loss of power, I would suggest burning the 1st couple of tanks w/91. The ry a tank or 2 of 87. See the difference. The loss of power vs. savings may b what you want.
Last week at the Mesa Ride and Drive, I spoke to one of the guys working the event. I was fortunate enought to spend some time with him on a drive during the lunch break. One of the tips he offered was to ensure I use premium gas, as you will notice a lack of performance without it.

thanks to all that replied. it sounds like i need to run 91 octane if and when my babe arrives.went thru the long wait when i ordered my prius a year and a hlf ago. the engine rerminds me of the type engine my 1st 240z had. it was a straight 6 single over head cam of 145 cu inches and 150 horses. back then you couldnt get a 4 cylinder to put out 177 hp and be reliable. also red line was 6500 rpm which back then in 71 was monstrous.

The car should run ok on 87, but it is not that much more economical to do so. Over the course of a year, the average driver would only save about $200 by using 87 instead of 91. That is not all that much, and only works out to be $2-$2.50 a tank. I bet I could save enough somewhere else every week to pay for the premium.
Also, the power loss could be significant since the engine has to retard timing for 87 grade to prevent knock. Potentially as much as 15%
Also of note, it takes the computer a few tank fulls to adjust. So if you run 87, you will have to fill up a few times with 91 before the computer fully restores timing and full power.

Just a little food for thought. While the manual recommends 91, most gas stations don't sell 91. At least none in my part of the country. The standard break-out at gas stations in NJ is:
Regular - 87
Plus - 89
Premium -93
If gas stays as expensive as it is now, I plan to do the break-in period at 93 octane, then run a tank or two on the 89 octane mid-grade, and see if I notice a drop in performance. Then I'll decide from there. If the verdict is that the engine really needs premium, it will probably take more than a few tanks before the engine resets for the premium gas, but I don't think it will harm the engine.

95% of gas stations in Indiana don't have 91 either (87, 89, 93)... but if you go to a cheap gas station (like GasAmerica) they have FIVE grades (85, 87, 88, 89, 91).
[QUOTE=dengel]Just a little food for thought. While the manual recommends 91, most gas stations don't sell 91. At least none in my part of the country.
How about 1/2 tank of 89 and the other 1/2 tank of 93 ? Wouldn't that give you 91 ?

From what I've read, that's exactly what the gas stations do. They only have 2 tanks, one regular and one premium. By varying the percentages of each, they can have 3, 4 or 5 different octane levels.

You mean I can't buy 91 octane 'cuz the gas stations aren't mixing it that way? Those bastards! Maybe I will mix my own.
