There is no better. If your car is designed to run on 87 octane then using 93 octane is a total waste of money. The higher octane will provide no more power, no better fuel economy, and is of no benefit to the engine whatsoever. In fact using a high octane fuel in an engine designed for 87 octane may actually cause hard starting. Use exactly the octane as recommended by the manufacturer of the vehicle. Saying that, if your car is designed to run on 93 octane then using 87 octane can be detrimental to the engine due to pre-detonation that will be caused by running the lower octane fuel. It depends on whether the manufacturer recommends the use of higher octane fuel or says it is mandatory. Most vehicles built in the last few years where 93 octane is recommended can run on 87 octane with a slight loss in power. The engine fuel management system will adjust for the lower octane and there will be no harm to the engine. The bottom line is to use exactly what the manufacture recommends.
The highest octane non ethanol gas available at least 91 octane
I'm asking the same question, just spent $500 (reasonable, too) replacing fuel pump, filter, sending unit due to ethanol deterioration. I know of a Shell station that has "Marine Gas" which is 89 octane non-ethanol, for the price of their 93 octane.
The best one that I know about is the "sliver eagle" gas station in heber. It's 91 octane as well. My boyfriend swears by it.
Octane is neither strong nor weak it is a non elecrolyte.
to my knowledge all 90's model 300zx require premium unleaded fuel only. its usually between 91-94 octane depending on the gas station.
Kelly's Resort has boat gas in the summer. The gas is non-ethenol which is better for boat engines. They also have a small grocery store with wine, ice, ice cream, cigarettes and a ton of provisions. By the way, they also have excellent espresso and probably the best view for sipping a beverage on the lake. Kelly's is accessible by boat or car and is on the South Lakeshore Road between the State Park and 25 mile Creek.
In Indiana, non-ethanol gasoline is typically sold at select independent gas stations, marinas, and some convenience stores.

Octane requirements for non-turbo (naturally aspirated or NA) cars are very low. 87 octane should be used if available. Always use the lowest octane fuel you can find. Higher octanes will result in a noticeable power loss, excessive carbon build up, and poorer mileage.
Water and octane are practically non miscible.
Octane is a straight chain molecule with a large surface area and stacks easily with other octane molecules. This increases the strength of the London dispersion forces that keep the octane molecules attracted to each other. The London dispersion forces on octane are greater than for smaller straight chain molecules because octane is both heavier and has more electrons that make it more polarizable.
In Oswego, NY, non-ethanol gas stations can be found by checking local directories or websites that list fuel options. Stations typically offering non-ethanol gasoline include some independent and regional chains.
