it will give you a little bit over 91 octane, and you'll only be buying 10 gallons worth of premium.

Bob, You might want to check into the local availability. After compairing costs, this may be an option you can use.

In fact, there's a station near by me that carries 100 octane at the pump (~$4.50/gal). 5 gallons of that mixed with 11 gallons of 87 octane would equal one full tank of 91 @ a cost of $22.50 (fuel capacity of the WRX is 15.9 gallons).

....and actually....yes. He could potentially save money. Using prices here in Lake Forest (since I don't know what it would cost him in his area) 5 gal @ ~$4.50/gal = $22.50 (remember...he doesn't pay for the 10.9 gallons of 87). 91 is ~$2.13/gal which equals $33.87 (a $10 saving on every fill up). I fill up once a week. That would be a savings of a little over $44 a month using my mileage in this scenario.

thanks for the suggestions, but i havent been able to find a station that carries 100 octane in the sacramento area. im not saying that they arent here, but i just dont know where they are and for your idea to be practical for me it would have to be pretty close to my work.
i need to do a search and find how much toulene costs and how much i need to add to 87 oct to get at least 91. that way i could just leave a big jug of it outside by the pumps...
of course if any of you guys know this off the top of your head and wanna save me a search, feel free!

I really like the car too, so it was dissapointing to have it feel so slow.

Why do we only have sh!te 91 Octane here in California? Anyone know? 91 is the regular grade back in New Zealand, premium is 96, from memory I think they even have 98 available in Europe. Means that European manufacturers have to de-tune motors to run in the USA. Don't know what the best grade is in Japan, anyone?

It's unusally low, even for Ohio....last month is was running $1.75 (which I guess is still low compared to CA)...

Octane calculation is usually Research + Motor number divided by 2 (R+M/2). The research octane number is usually high (IIRC between 88 and 100 octane) and the motor octane number is low (IIRC between 84 and 90 octane). I've seen gas stations in other countries that report only the Research Octane Number, which makes it look high. In reality, it's usually the same grade as the gasoline sold here.
