What is the octane for jet fuel?
The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.
Jet-A, the most common type of jet fuel, is made from kerosene and is similar to diesel fuel. Avgas is similar to what you use in your car, but it's not intended for that use.
What octane fuel should I use in my vehicle? You should use the octane rating required for your vehicle by the manufacturer. So, check your owner's manual. Most gasoline vehicles are designed to run on 87 octane, but others are designed to use higher octane fuel.
Regular gas with 87 octane level is suitable for most engines, while premium gas with higher octane levels (91-94) is required for some high-output engines. Engines designed for regular-octane gas gain little to no benefit from using high-octane fuel.
Avgas remains the only transportation fuel in the United States to contain lead. More than 222,600 registered piston-engine aircraft can operate on leaded avgas. The most common and reliable type of avgas is 100 octane Low Lead, also known as 100LL.
This makes jet fuel safer than gasoline. It also means it has higher octane ratings, meaning it produces greater power and is more efficient.
Ammonia (NH3) is perceived as a potential fuel for gas turbines as it has a high H2 content but not any carbon atoms. Ammonia, mixed with H2 or LCH4, can be used as aviation fuel in low blending or as a dual fuel solution in modified aircraft engines and fuel cells.
JP-5 is the U.S. Navy's primary jet fuel, and JP-8 is one of the jet fuels used by the U.S. Air Force. Both JP-5 and JP-8 are colorless liquids and smell like kerosene, flammable and toxic for human. JP-5 and JP-8 can be made from refining crude petroleum oil deposits found underground and under the ocean floor.
Jet-A is closer to kerosene and Diesel #1. Most modern diesel engines specify Diesel #2. 4. The viscosity specifications for the two fuels is different.
Common applications for these 100 octane fuels include road course, asphalt oval, dirt oval, rally, drag, truck and tractor pulling, motorcycle road course, off-road motorcycle and ATV, karts, boats and personal watercraft, muscle cars, vintage cars, and more.
What octane is Japanese fuel?
High-octane gasolines commonly sold in Japan normally have 98-100 octane rating regardless of brands. There are only two types of gasoline sold in Japan. Med-grade gasoline with octane rating 95 or similar, which is sold in many other countries, is not available in Japan.
Premium (the highest octane fuel–generally 91–94)
The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive. “That said, if your vehicle requires premium fuel, it's a good idea to top it off with the good stuff as soon as you're able,” the website said.
Engine computers can usually adjust their timing to account for the increased octane levels, so if you put premium gas in a regular car, you probably won't notice anything. However, some engines are not designed to burn higher-octane fuel, and you may see a reduction in performance and fuel economy.
Generally, the octane number (ON) of gasoline is in the range of 70–97, whereas the octane number of kerosene is much lower as only 20–50.
For starters, there's a higher level of sulfur and other additives-including cetane, and the cetane number-in Jet-A than is allowed in your diesel. This could lead to fines and may even damage your engine.
While some airplanes still use leaded fuel, unleaded fuel is far more common. Almost all commercial airliners, for instance, now use unleaded fuel. Many small airplanes also run on unleaded fuel. Commercial airliners and other modern airplanes typically run on a type of kerosene-based unleaded fuel.
Jet-A (freeze point of -40°C) and Jet-A1 (freeze point of -47°C) are highly refined kerosene-type fuels used in commercial and general aviation turbine engines.
Jet-A is used in a much higher volume than 100LL. All the jet engine commercial aircraft each day burn through orders of magnitude more Jet-A than piston aircraft burn through 100LL. That means that there is a much higher production volume, and therefore a cost savings as a result.
However, compared to a kerosine-type fuel, wide-cut jet fuel was found to have operational disadvantages due to its higher volatility: Greater losses due to evaporation at high altitudes. Greater risk of fire during handling on the ground. Crashes of planes fueled with wide-cut fuel were less survivable.
Why is jet fuel so expensive?
Prices for the kerosene-based product have been climbing since December, propelled by diminished supplies after winter storms shut down refineries. Swelling demand has also pushed up prices, as millions of Chinese travelers took to the skies to celebrate the Lunar New Year and newfound freedom from Covid restrictions.
To elaborate on the other answer, you don't actually need any fuel or oxidizer to run a jet engine. Jet engines are just a type of open-cycle heat engine where the atmosphere is the working fluid and thrust happens by expelling it as reaction mass.

| Nationwide | 3627 | $6.17 |
| Alaska | 79 | $7.61 |
According to Air Force policy, fuel is discharged only for emergencies, precautionary landings, other safety-of- flight considerations, or urgent operational requirements.
Turbine Fuel Low Volatility JP-7, commonly known as JP-7 (referred to as Jet Propellant 7 prior to MIL-DTL-38219) is a specialized type of jet fuel developed in 1955 for the United States Air Force (USAF) for use in its supersonic military aircraft, including the SR-71 Blackbird and the Boeing X-51 Waverider.
JP-8 is the military equivalent of Jet A-1 with the addition of corrosion inhibitor and anti-icing additives; it meets the requirements of the U.S. Military Specification MIL-T-83188D.
Lower Cost
Along with its lower freezing point, higher flash point and lower viscosity, this is one more reason why kerosene has become the preferred type of fuel in the aviation industry.
Steel melts at 2,750°F, and jet fuel burns at temperatures of 800-1,500°F, so it doesn't reach the melting point of steel but rather holds about half its strength when heated up to 1,100°F.
The Jet A fuel flash point specification is 100°F minimum, and other fuels are different. For example, JP-5 specification is 140°F, which means that the fluid has to be heated to at least 140°F in order to give off enough vapors to be flammable.
Cars with high compression ratios, particularly those fitted with turbochargers, are often recommended to run on premium gas for peak performance. By that, we mean more than snappy acceleration times. Gasoline impacts your car's performance as well as fuel economy and emissions levels.
Can you put 99 octane in any car?
The only vehicles that need premium fuel to keep their car running are petrol engine with high compression ratios. This usually refers to high-performance vehicles that often need super unleaded fuel to run properly.
If you are unsure about what your car needs then check the user manual, which will say if you need to use unleaded fuel with an octane rating that is higher than 95. That being said, it isn't a necessity for the majority of vehicles so whether you use a higher grade fuel is down to your own discretion.
Thailand's new legal octane specifications for gasoline are intended to match more closely the actual engine requirements of the country's vehicles. The revised official octane grades for Thai gasoline will be: regular gasoline, 87 research octane number (RON); mid-grade, 91 RON; and premium, 95 RON.
Gas stations in Hong Kong mainly supplies 98-octane unleaded gasoline while most car engines on the other hand are designed for 95-octane number gasoline.
You'll know you're filling up with the good stuff if you spot a small green sticker on the pump that says “TOP TIER Detergent Gasoline.” As of early 2022, the following stations sold Top Tier gasoline in the U.S.: 76, ARCO, Aloha, Beacon, Breakaway, CITGO, Cenex, Chevron, Conoco, Costco Wholesale, CountryMark, ...
Higher-octane fuels can stand more compression before automatically combusting. New Shell V-Power unleaded is a 99RON octane fuel. By comparison, regular Shell unleaded is 95RON. New Shell V-Power unleaded -the power of high octane.
If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don't worry. You're actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.
You can use gasoline to lubricate some parts of your car. Gasoline contamination can cause a reduction of diesel flash point at some time. Remember that gasoline does not damage your diesel engine. An accidental mixture of diesel fuel to gasoline isn't risky, but it needs to be prevented.
Excessive viscosity will affect pressure, or if it's too little or too clear, the engine will have to work harder than necessary. For diesel and gasoline engine oil the car user shouldn't be mixed it shouldn't even be done. Except in an emergency, which should be taken immediately to prevent engine damage.
Don't worry about it. Red containers are all I have and all I have ever used to carry off road diesel when I buy it at the roadside station. A little gasoline wont hurt the the diesel. The lubricity being reduced is the biggest issue if diesel is diluted with too much gasoline.
Can you put 93 gas in any car?
Let's start with the easy one. Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.
Additionally, premium gas can increase fuel efficiency, potentially bringing better gas mileage for longer while decreasing emissions. Remember that these benefits are seen in vehicles that truly require premium gas and not necessarily in most other vehicles.
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular octane. The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging.
Using pure gas can lead to better mileage. But increased fuel economy from using ethanol-free gas may be offset by its higher cost. Non-ethanol gasoline typically costs more than ethanol-blended varieties. Using non-ethanol gas in your car won't harm the vehicle's engine.
Sure, you won't hurt your lawn mower or string trimmer by putting in Premium gasoline, but you'll be wasting your money since it's more expensive. Contrary to popular belief, Premium gas does not improve fuel efficiency or performance in motors that don't require it.
If your 80 gallon tank is full it won't hurt anything. If it only has 5 gallons in it that is another story, top it off with diesel. 5% gasoline won't hurt anything. VW and Mercedes used to even suggest adding up to 20% in cold climates in the 70's and 80's to help starting if you didn't have winter blend fuel.
The JP-8 is a kerosene which contains additives with the objective of improving its properties for military use. As such, it is used in military aircraft with the exception of reactors loaded on aircraft carriers, which use JP-5. JP-5 is also a fuel derived from kerosene.
Cetane rating is the diesel equivalent to gasoline's octane rating. Unlike an octane rating, which rates gasoline's resistance to spontaneous ignition, the cetane rating number (usually 40 to 55 for medium to high speed engines) notes the relative ease with which diesel fuel ignites.
For all engines except the 300hp Rotax 1630 ACE - 300, look for unleaded fuel with an AKI (RON+MON)/2 octane rating of 87 (or an RON octane rating of 91). Craft using the high-performance ACE - 300 engine require a higher octane level for best performance, fuel economy and engine life.
Actually, Diesel engines can run on any of the heavy Tanes; like Jet fuel and Kerosene. The problem as expressed in Jet-A, is that it has more Sulphur and Cetane than a Diesel can deal with.
Does jet fuel burn hotter than gasoline?
This means that jet fuel can reach higher temperatures before it combusts, up to about 300°F (149°C) for Jet A and 500°F (260°C) for Jet B. So when comparing the heat of jet fuel and gasoline based on combustion temperature alone, jet fuel burns hotter than gasoline.
1 The CIS and parts of Eastern Europe use a Russian fuel, TS-1, which is a light kerosine-type fuel. Jet A is used in the United States while most of the rest of the world uses Jet A-1.
Jet fuel is a clear to straw-colored fuel, based on either an unleaded kerosene (Jet A-1), or a naphtha-kerosene blend (Jet B). Similar to diesel fuel, it can be used in either compression ignition engines or turbine engines.
