I mean, it accelerates better, hesitates less, and knocks very little on Super Unleaded as compared to driving on Regular Unleaded. So a gallon of it should drive my car further (more mpg) than would low-octane gas, right? How much further? Enough further to offset the price difference? What factors work into the equation? Do I need to be able to change the mixture setting, compression, spark advance, or whatever, to make a difference? Will the higher temperatures hurt my engine at all? -- Human: Bob Sutterfield Facilities Management Division The Ohio State University Instruction & Research Computer Center Workplace: Ohio Cooperative Extension Service, Computer Management Group OCES VAX System Manager/Programmer (VMS) Mail: ...cbosgd!osu-eddie!sutter.UUCP or: sutter@ohio-state.CSNET MaBell: (614) 422 - 9034 Brought to you by Super Global Mega Corp .com
