What’s the difference between 91 octane and 95 octane?
Summary – 91 vs 95 Octane Fuel. Octane rating is a measurement of the performance of a fuel. Therefore, fuels are in several forms depending on the octane rating.91 and 95 octane fuels are two such forms of fuel.

What are the numbers in the octane rating of petrol?
Those numbers – 91, 95 and 98 – are the so-called ‘octane rating’ of the fuel. They’re all about the same in terms of the energy in the fuel.
Why is 85 octane fuel allowed in gasoline?
The sale of 85 octane fuel was originally allowed in high-elevation regions—where the barometric pressure is lower—because it was cheaper and because most carbureted engines tolerated it fairly well. This is not true for modern gasoline engines.

Which is the correct octane rating for gasoline?
Selecting the Right Octane Fuel. What is octane rating? Octane rating is the measure of a fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88–90 (midgrade), and 91–94 (premium).
