how to mix to get 93 Octane

I work in Menlo park and there is 1 76 which sells 100 and 91. What is the correct amount to make 93 octane for a full tank of 13 gal.

3 gallons of 100 and 10 gallons of 91 makes 13 gallons of 93.08 octane.

Here's a tool you can use. http://home.comcast.net/~davephoward/Torco.xls

depends on how low you let your tank get.

When I fill mine I am adding about 13 gallons.

at $4.79 a gallon for 100 octane you should be around 94-95 octane.

LOL, at such expensive prices now a days, premium going for about ~3.30-3.45, it makes the 100 octane seem pretty reasonable, I remember at so cal station where they were $5ga; and regular gas was about $2/gal, quite a few years back of course, and that seems much less affordable :P

I filled up just over 10 gallons last night of 100 octane. So now I must have just over 96 octane.
