Your car needs 91 octane as a minimum, to prevent the remote possibility of engine damage by knocking, and also to produce the advertised amount of power.
I have read studies that confirm that using a higher octane than recommended is a waste of money. No added performance, no appreciable gain in fuel economy - and ironically, the benefits are the least on more efficient / high specific output engines like in the e9x |

it's more like : whats another 4,5 bucks extra per tank over the 91.
2 fill up per week $5 x 4 = 40 bucks extra a month and a whopping 480.00 per year wow!!! why not waste your money ?? ... LOL

I believe Procede comes with different maps - 91, 94 and higher ones for racing fuel. If you are on a 91 map, 94 won't give you any extra gain . If you are on a 94 map you have to use 94 all the time. So if you can't find a station that sells 94 while on the road you are SOL. I had heard from somewhere that it can be dual loaded with 2 maps and select with a toggle switch. I IM them awhile back to ask about it but they did not reply.

I am aware of two cases (one in Montreal and one in BC) where they use 94 and their HPFP failed.
