I usually define a HIGH GRADE FUEL the fuel that presents a very good quality in comparison to other similar fuels. It is not an absolute concept but a relative one. For example, talking about fuel gases in general, liquefied petroleum gas and natural gas can be considered high grade fuels, because other fuel gases as coke oven gas, blast furnace gas, landfill gas and producer gas present lower qualities due to particulate matter, tar, moisture and sulphur compounds. Another example, talking about diesel, the diesel 50 (50 ppm of sulphur) is a high grade fuel in comparison with other diesel fuels which present higher sulphur contents.

Jet fuel is high grade diesel so a jet fuel car would use high grade diesel fuel.
92 octane because of the high compression
No, because airliners need a lot of high grade fuel to fly, and vegetable oil is VERY low grade.
Jet fuel is basically just high grade kerosene, with some iceing & microbiological contamination inhibitors added.
If the pressure is too high for the grade of fuel, you will get 'pinking' or 'pinging'. This is the term for pre-ignition. The fuel will explode instead of burning rapidly, and makes a metallic rattling or 'pinking' sound. This can damage the valves and piston crown if left to continue. High compression engines need a better grade of fuel, a higher Octane number.
it is based on Octane levels, you have your standard 89,91,93 octane regular gas, and racing fuel is closer to 117 octane hope that helps
== == Automobiles with gas or petrol engines require either regular grade gasoline or super grade. The vehicle's manual will tell you which grade of gas is required. If you fill a vehicle requiring regular fuel with the more expensive super, you are wasting money, as there is no appreciable gain in mileage, engine longevity, etc. However if you put regular fuel into a vehicle requiring super (due to high compression ratio of many sports cars, high-end sedans, etc.) you can cause the engine to knock and cause carbon deposits to build up in the engine. Mid grade can sometimes be used in a mix with super to lower fuel costs, but this is not recommended by automobile manufacturers. If you want to know about using the wrong kind of fuel - in the case of a gas or petrol engine putting diesel in its fuel tank, or putting gas or petrol in a vehicle that has a diesel engine - see the answer to the Related Questionshown below.
high grade
Your owner's manual says the fuel grade that your car was designed for. Some cars have stickers on the fuel filler door stating the fuel grade.
The high-octane fuel is recommended for high-performance sports cars to maximize engine efficiency and horsepower.
Piston powered aircraft (small helicopters included) run off a high grade petrolium called AvGas... however all jet turbines (engines) ,run off very high grade Jet A1 fuel......which essentially is just treated kerosene fuel.
Yes. You start high school in 9th grade and end at 12th grade.
