Shell 93 octane fuel typically does not contain ethanol, but it is always recommended to confirm with the specific Shell gas station you are visiting, as ethanol content in gasoline can vary by location.
Pure on the corner of Fairlawn and Reynolda has Premium without ethanol.
All gasoline except premium is mandated to have at least 10% ethanol. Sorry. Some stations (brands) have premium with out ethanol (Missouri law allows this), the trouble is finding out who has it. Ethanol does substantial damage fast in small engines and cars older that 14 years and some damage in newer cars. Do not use ethanol with a fiberglass or plastic gas tank=engine suicide.
manufacturer recommends using 93 premium gas only.
Butler's garage, Hardeeville, SC (5 miles north of the SC-GA line on I-95) sells both regular (87 octane) and Premium (93 octane) fuel without ethanol. He was an Exxon station, but when Exxon insisted that he sell fuel with ethanol, he gave up his franchise and became an independent. Also does other work on cars. Open daily from 7am to 6pm, Saturdays to 2pm, closed Sundays.

These days, they all do--which makes having your plane STC'd for auto gas slightly worse than useless. If you can't get legal gas, why do it?
2003 blazer with a 4.3 does not need premium gas, but should not knock unless there is water in the gas or you are using ethanol based gas. It would not hurt to try a bottle of injector cleaner, I prefere Techton but others will do. also chech your air filter.
I use premium, 91 or 93 octane. Depends on what the gas station carries.
