Some of the Sunoco Gas station around here have 94 octane (or is it 95?) fuel. Will there be any benefits in using this fuel in my 8? It's only a 1 octane difference.

other threads have addressed the 'difference' question and general consensus seems to be that the best octane is the lowest you can run in your car and not lose anything. I've been trying 87 and right now back to 93 this tank. I'll have to fill again tonight and may add 93 again - but at 1/2 tank I had about 148 miles, and had 146 - 149 with the lower octane. Power doesn't seem lower with lower octane nor does it seem faster now with 93 running. I may opt to just some premium and hope to run some 1/4 miles tomorrow evening, and if I have the time may go out and get some lower octane and go back for a run or two.
Others have posted their own 1/4 times on I think 89 and 93 octane and IIRC had small differences. If I can't see or feel any diff I may stick with 87 or use 87/89 (I have to fill every 2 - 3 days).
