Have noticed lately at my local Shell dealer, as well as Exxon/Mobil, some rather aggressive advertising for their Premium fuel, indicating that it's better for your engine, causes less friction, higher mileage and, of course, cleaner. I guess conventional wisdom says that an engine set up to run on 87 would not run optimally on 93 as the computer is "looking" for 87 and would have to adjust when the burn rate of 93 is detected. I have some difficulties rationalizing all the above "magical" benefits as well as doing the math for higher mileage when the 93 is .60 cents more a gallon, which is a 20+% increase. IMHO, this is a FUD (fear, uncertainty & doubt) advertising program to sell a more profitable fuel by trying to convince you that its "better". If your engine is designed for and needs Premium, probably an excellent fuel, however all the benefits described won't make much, if any, difference in a regular gas engine, other than increasing your cost per mile. Toptier does make a difference in a DI/Turbo engine, but it's benefits are in all octane levels.
