The fuel consumption of a jump depends on a variety of factors, including the distance of the jump, the mass of the ship, and the route taken. Generally, longer jumps use more fuel than shorter jumps, and the fuel efficiency decreases as the jump distance increases. The route taken can also impact fuel consumption, with economical routes using less fuel by taking shorter jumps, while faster routes use more fuel with longer jumps. Additionally, the mass of the ship can affect fuel consumption, as more fuel is required to move a greater mass. To determine the exact fuel consumption of a jump, players can refer to tools such as the Galaxy Map, which provides information on the number of jumps possible with a given fuel load.

What You'll Learn
Short jumps use less fuel than full-range jumps
When it comes to fuel consumption, short jumps are more fuel-efficient than full-range jumps. This is because the amount of energy required for a jump is proportional to the square of the velocity, so a single jump of twice the distance would use four times the fuel. As a result, the fastest route, which involves fewer longer jumps, consumes significantly more fuel than the economical route, which takes longer but uses less fuel by utilising numerous short jumps.
For example, a 5LY jump range might only use 0.5 tonnes of fuel. This means that with 50 LY, you could make ten 5LY jumps, whereas with 100 LY, you could make twenty 5LY jumps. Alternatively, you could make four 2.5 LY jumps with 10 LY, or increase the jump range to 10LY and make ten jumps to cover 100 LY.
The fuel efficiency of a jump is also influenced by the weight of the cargo and the fuel tanks. A ship with a higher cargo load will require more fuel to travel the same distance. Additionally, the fuel efficiency decreases when jumping at the maximum distance, as longer jumps waste more fuel. This is because the jump range changes slightly based on the amount of fuel on board, and stopping to refuel can result in replotting a different course with shorter jump ranges.
To optimise fuel usage, players can opt for economical routing, which restricts jump length to conserve fuel. This is particularly recommended for newer players to avoid running out of fuel prematurely. By switching to fast routing, players can utilise their full jump distance but at the cost of increased fuel consumption.

Fuel efficiency decreases with longer jumps
Fuel efficiency is a key consideration when planning a journey, and this is no different when it comes to space travel. In fact, the fuel efficiency of a spacecraft decreases with longer jumps.
The "Fastest Route" option on the galaxy map will get you to your destination more quickly, but it uses much more fuel than taking a more economical route. This is because it takes much more than twice as much fuel to jump twice as far. The longer the jump, the more fuel is wasted. This is because the FSD (Frame Shift Drive) has to impart faster and faster velocities to the ship for the longer jumps, and this requires more energy and, therefore, more fuel. The amount of energy required is proportional to the square of the velocity, so a single jump of twice the distance would use four times the fuel.
To put this into context, a 5LY jump range might only use 0.5 tonnes of fuel. Using those figures, you could jump 50 LY at 10LY per jump, or 100LY at 5LY per jump. However, if you were to increase your jump range to 10LY, you would use much more fuel per jump and would not be able to jump 100LY without refuelling.
Therefore, if you are planning a long journey, it is more fuel-efficient to take lots of small, short jumps than to jump your maximum range each time. However, this will take longer as you will have to jump more often.

The fuel gauge in the cockpit shows how much fuel a jump will use
The amount of fuel used per jump depends on the distance travelled. Longer jumps require more fuel, but fuel efficiency decreases as the fuel limit is approached. Therefore, multiple shorter jumps may be more fuel-efficient than a single long jump. The "Fastest Route" option on the galaxy map uses fewer, longer jumps, while the "Economical Route" option employs more short jumps.
The fuel gauge is an important tool for pilots to monitor their fuel usage and ensure they have sufficient fuel for their journey. By selecting a jump location and observing the fuel gauge, pilots can make informed decisions about their route and fuel management.
Additionally, the fuel gauge can provide valuable information about the aircraft's performance and efficiency. For example, a jump that uses a large amount of fuel may indicate that the aircraft is carrying more weight or experiencing decreased fuel efficiency. By monitoring the fuel gauge, pilots can identify potential issues and make necessary adjustments to ensure a safe and efficient flight.
In conclusion, the fuel gauge in the cockpit is a crucial tool that displays the amount of fuel required for a jump. It allows pilots to plan their routes, manage their fuel efficiently, and make informed decisions about their aircraft's performance and fuel consumption.

The Economical route option provides the lowest fuel usage
When it comes to fuel usage, the length of the jump is a key factor. The fuel consumption for a single jump at maximum distance is more than for two jumps at half that distance. This is because fuel efficiency decreases when jumping at the biggest possible distance.
The Economical route option, therefore, provides the lowest fuel usage. This option utilises multiple short jumps, as opposed to the Fastest route option, which uses fewer longer jumps. For example, if your ship can jump 30 light years (LY) at maximum range, you could jump 500 LY with 15 jumps of 10 LY each, or 1000 LY with 5 LY jumps. This is why the Economical route option can get you to your destination with the fuel you carry, while the Fastest route option may not.
The number of jumps you can make with your fuel load depends on various factors, such as the density of stars around you and the mass of your cargo. It's important to note that in-system flight also uses fuel, so it's advisable to avoid getting too low on fuel.

Fuel consumption is not proportional to distance jumped
For example, a 10-tonne fuel tank with a max jump range of 10 LY might have a "max fuel per jump" of 2 tonnes. This means a 10 LY jump will take 2 tonnes of fuel. However, for the same craft, a 5LY jump range might only use 0.5 tonnes. This means that you could jump 50 LY at 10LY per jump, or 100LY at 5LY per jump. This can be further increased if you used 2.5 LY jumps at only 0.1 tonnes per jump.
The galaxy map has "Fastest Route" and "Economical Route" navigation plotting for this reason. The fastest route gets you to your destination in fewer jumps but uses much more fuel. The economical route, on the other hand, uses lots of small, short jumps. While this will get you further, it will also take longer because you have to jump more often.
Additionally, fuel efficiency decreases when jumping at the biggest possible distance. This is because the longer the jump, the more fuel is wasted.

Frequently asked questions
The amount of fuel a jump uses depends on the jump distance. Short jumps use exponentially less fuel than full-range jumps.
The fuel used is equal to the jump distance (minimum 1, maximum = the J-Drive number) multiplied by 10% of the total hull volume. For example, a ship with a J3 jump drive rating will use 10% fuel for Jump 1, 20% for Jump 2, and a maximum of 30% for Jump 3.
Yes, more fuel is required to move greater masses. Additionally, your maximum jump range will be higher if you're not carrying cargo or if your fuel tank isn't full, as a lower total mass reduces fuel consumption.
When you have a jump location selected, your ship's fuel gauge will indicate how much fuel that jump will use. Additionally, the Galaxy Map will show your maximum range based on your current fuel load.
The "Fastest Route" setting uses fewer, longer jumps, while the "Economical Route" setting uses more frequent, shorter jumps. The "Economical Route" setting is more fuel-efficient, allowing you to travel further with the same amount of fuel.
