Thanks! That is very interesting. After the report from OH48Lt that the difference was quite noticeable I had made up my mind to try the higher octane to see if I could also tell a difference. As fate would have it at my next fuel stop premium was $0.80/gal or nearly 30% higher than regular. I couldn't bring myself to pay that much extra since I have never felt the need for more power and that really seemed like money just thrown away. I may still try some 93 octane if I can find it for a more reasonable difference.
