Diesel is heavier than gasoline
A gallon of gasoline weighs about six pounds, with slight variations depending on the type of gasoline and its additives. For instance, regular gasoline weighs about 6.073 pounds per gallon, while premium gasoline weighs about 6.27 pounds per gallon. On the other hand, diesel fuel weighs about seven pounds per gallon. This difference in weight is due to diesel having a higher density and a greater number of molecules.
Given that diesel is heavier than gasoline, it is important to never mix the two. If diesel is accidentally added to the tank of a gasoline-powered vehicle, it will sink to the bottom due to its higher density. This can result in the injection of both diesel and gasoline into the engine, leading to incomplete combustion and large amounts of black smoke. Additionally, the diesel can clog up the gasoline engine, causing serious damage to the vehicle.
The weight of 63,000 gallons of fuel, which is the capacity of a Boeing 747, is approximately 400,000 pounds. This weight is nearly equivalent to that of the empty plane. Thus, the weight of the fuel plays a significant role in the overall weight of the aircraft.
The difference in weight between diesel and gasoline also has implications for their use in different types of engines. Gasoline, being lighter, is better suited for smaller engines that require quick acceleration and deceleration. In contrast, diesel, with its higher energy density, is preferred for applications where strong and steady power is required, such as in trucks, trains, and ships.
In summary, diesel is heavier than gasoline due to its higher density and molecular composition. This weight difference has important implications for the use and performance of these fuels in various engines and vehicles. Understanding the weight of fuel is crucial, especially in industries such as aviation, where precise calculations are necessary to ensure safe and efficient operations.

A Boeing 747 can carry 63,000 gallons of fuel
A Boeing 747 aircraft can carry roughly 63,000 gallons of jet fuel. This amount of fuel weighs approximately 400,000 pounds, which is nearly as much as the weight of the empty plane itself.
The exact fuel capacity varies between different models of the 747, with some versions capable of carrying more than others. For example, the 747-8i Intercontinental has a fuel capacity of 63,034 gallons, while the 747-8f freighter can hold 59,734 gallons. The 747-400 model, which is noted for its improved range, capacity, and fuel efficiency, can carry 57,285 gallons of fuel, which is an increase of more than 9% over its predecessor, the 747-300, which has a capacity of 52,410 gallons.
The majority of the fuel on a 747 is stored in the aircraft's wings, with two main fuel tanks in each wing, reserve fuel tanks in the outer wing sections, and a central wing tank in the middle. This distribution of fuel helps to maintain the plane's balance and allows for greater storage capacity in the fuselage for cargo. Certain models of the 747 also make use of auxiliary fuel tanks in the horizontal stabilizer to further increase their total fuel capacity.
The weight of jet fuel is influenced by factors such as temperature and additives. On average, jet fuel weighs around 6 to 7 pounds per gallon, which is about 25% lighter than water. When converting jet fuel weight to gallons, a simple calculation can be used: drop the last zero from the total weight, divide that number in half, and then add the two new numbers together to get the approximate number of gallons.
