anybody know where i would be able to buy 93 octane at all??? or is it really just banned from cali? are there any effects or efficiency in using 91 instead of 93.. expecially after you had some power mods. etc etc. can anybody offer pro/con?

Go east of NV and AZ, there you go. It's not "banned" from CA, it comes do to the fact it takes more crude oil to process to get 1 gal of 93 vs 1 gal of 91.

CA just has too big of a demand for our suppliers.

In english, you will not find 93 at the pump in the state of califorina. but you can buy 100+ race fule see chart for what to do next.

As 06STi said, mixing is the best way to go.

Here's a link for a 100/110 octane thread I started a while back.

anybody want to emphasize alittle more on the benefits mixing the gas will do? i heard it was bad to mix gasoline at all. are you guys doin that for daily driving ?? or for track.. O.o

Mixing gas is perfectly fine. 91oct(x) + 100oct(y) = desired octane =P

Main point in mixing to a higher octane is a cleaner burn during compression process, plus it prevents detonation at higher temp environments.

ECU will also adjust timing to take advantage of the better fuel composition. Resetting the ECU greatly speeds up this process but is also recommended if you go lower in octane rating.

Some say they gain a small amount of HP but I don't think it's noticeable. Others say you improve gas mileage. IMHO, the cleaner burn does make the car run smoother.

I wouldn't recommend running this daily, it's something worth using for track days or any racing environment that raises the operating temp to the point where detonation occurs. If you just want to see how it runs with a cleaner burn I'd try it once in a while as it will also run smoother.

Since the mid-west and east coast get 93 & 96 octance our US ECUs should be able to compensate for this higher octane mix.
