Planet 9

Hey all,
First time poster here. Quick question, I have an 08 CS with the APR flash. I would like to be able to use the 93 octane program, however, cannot find any stations that sell anything over 92. Anyone know of any. Thanks in advance!

Here is a link to a Googlemap that I am putting together for 100 Octane and a blending calculator:

and

and before you ask the tank on the car is 16.9 Gallons

I appreciate the response. Not necessarily looking for racong fuel though, just 93 octane. Anyone??

I think Nick_USA is suggesting that you can blend 100 octane with 87, 89, 91 or 92 to get you up to the 93 you are looking for.

FWIW, in the twin cities area, 91 or 92 is as high as most stations go. Holiday stopped carrying 93 about 2 years ago. dfogal told me there is a place near hwy 169 & Rockford Rd, next to Taco Bell, that sells 100 octane unleaded. I have yet to visit there myself but plan to check it out soon.

Looks like blending is the way to go. Thanks for the help!

Well I found 110 octane in Lakeville, however, it is leaded. Even though it would be blended, from my searches, leaded fuel can do alot of engine damage. Is this true? I just want to be able to run my apr flash on 93 octane. Unfortunately on the 08 CS, you can only choose 1 program at install. I originally wanted that flash for the flexibility of being able to switch "on the run". This is not the case with the new ECU on the 08. Even though I run 92, they told me I cannot run the 93 program. The 93 is worth an extra 6 hp. Not a ton, but every bit helps, right? So, to blend or not to blend?

Blending is the way to go but..... Do NOT use leaded fuel as it will mess up the Cats and you will end up with CELs.

Exactly what I thought. The search continues for high octane unleaded. Thanks for the help.
