Curious, I have always used 93 octane in my 2002 S281 N/A. I think that you can use 91 octane (correct me if i'm wrong). Now that gas is a freaking rip off and the 93 octane is 20 cents a gallon more, i wouldnt mind using 91. Has anybody been running 91 octane with no problems?

Yeah, mine runs awesome on 91 pump gas
