The Fuel Pressure on a given ccar varys from car to car, Manufacturer to Manufacturer.. You should not list a Static # as such.

You mention Catalytic Converters, But nothing about What they actually do. It should be mentioned that the way they manage their task is by being filled with a catalyst That Heats to a Pre-designated temp and at that point Reacts with the Gasses Flowing through it.

Octane Rating COULD be described as a particular fuels resistance to Knocking or "Detonation" (Detonation should be referenced, Since Knocking is actually the noise Caused by Detonation or Pre-Ignition.) But octane actually has little to do with it in a Poorly tuned car. Octane Technically refers to a Fuels anti-knock properties, But More directly it refers to the speed at which Fuel Burns. Low Octane fuel is in fact more prone to pre-ignition bcs of its ability to burn quickly. So in a poorly tuned car where Detonation is occurning and the Cylinder walls of the engine are too hot it will ignite simply from the temperature in the cylinder rather than from the Actual Spark from the spark plug. Whereas A High Octane Fuel will not Ignite at those temperatures. Giving an Engine more room to create and properly disperse heat.
