Now i am notentirely positive, but its because high octane fuel burns easier, so the jet engine doesn't need to be very complicated to work in the air. Also the air up i the atmosphere has a less concentrated amount of molecules, i don't know why that has something to do with the high octane gas but, you never know. And the higher octane needs less, to do more. So it makes the plane lighter and can hold more.
The grades gasoline are the different octane ratings, the cheapest gas has the least octane. The lower the octane in the gasoline, the faster it will burn. High performance cars need high octane fuel.
Unleaded is choice. Manufacuters recommend a minimum octane rating of 87. In high altitude, 85 octane is acceptable.
Octane rating is the resistance to burning. For example (not real number) a gas with an octane rating of 50 will burn at 100 degrees Fahrenheit whereas a gas with an octane rating of 100 will burn at 200 degrees Fahrenheit. Higher the octane number the harder it is to burn.
Your average automobile will burn 87 octane unleaded gasoline. Some more sporty cars will burn 92 or 97 high octane unleaded fuels. All of which are a petroleum by product.
burn high octane and keep it under 2000 rpm
Octane is a chemical in gasoline that causes it to burn well... copper won't do anything... octane is a natural gas... uh... what? no!
it's a little better than 87 octane but not really high test gas, 91 and 93 octane is the high test.
no
Most professionals recommend that you use high octane gas. Like 92-94 octane.
Premium or high octane
yes
Yes, we even had High octane !
