I can only speak of 92-93 octane fuels used in my 285 hp SRT4 Neon.
In all cases the 93 allows more boost than 92 or 91.

My best boost comes from BP and Marathon. Next best power comes from Speedway and Shell.

In the late 80s and 90s Marathon was the provider for Speedway, but now their oct differs...don't know what is up with that.

Any gas with a 10% mix I stay away from except in emergencies....they cost the same around here but it kills my cars power and FE...even my 3 cyl Metro gets worse FE with it.

Many stations have troubles with rain water getting into their tanks, then into your car. A dealership that sponsored my cars would have at least 5 cases a week where people with their Chrysler products could barely make it in or had to be towed in....in every case they had filled up at a no name gas station 13 miles away....a sample of the fuel in a clear glass would show the destinct settling of the water and fuel! Eventually those tanks were repaired.

In the late 70s I had gotten out of the Army and found a job at Monkey (Montgomery) Wards....the mgr of their "gas" station was always amazed that they would sell more a month than the tanks would hold!
