# What Does 1 Gallon Of Diesel Weigh?

Yes, but only a smidgeononononononononononononononononon (check out this calculator if you want to see how much). At 16°F, a gallon of diesel weighs 7.1 pounds; at 106°F, the same gallon weighs 6.8 pounds.

## What does 4 gallons of diesel weigh?

Fuel is the lubricant that keeps trucks on the road. If you want to haul profitable goods and keep your trucking firm afloat, you’ll need diesel fuel to get from point A to point B.

Although it’s a simple calculation, have you ever considered the intricacies of diesel fuel? Have you considered how much diesel fuel weighs? What’s the weight of a full tank of diesel fuel? Is there a difference in the weight of diesel based on the outside temperature? How does the weight of diesel fuel affect the weight of your truck, especially when it’s time to weigh it?

### What is the weight of diesel fuel?

A gallon of diesel is approximately 7 pounds in weight. In the United States, diesel weighs somewhat less than 7 pounds per gallon (and slightly more than 7 pounds per gallon in Canada), but we’ll use 7 pounds per gallon to keep things simple.

### What is the fuel weight of a full tank?

Semi-truck fuel tanks are available in a variety of sizes, but they typically store 125 to 300 gallons of petroleum. Each side of the tractor has a gasoline tank, with fuel apportioned between the two tanks to balance the truck’s total weight. Because diesel fuel weighs around 7 pounds per gallon, a full tank of diesel might weigh anywhere between 875 and 2,100 pounds.

### Does the weight of diesel fuel change when it’s colder vs. warmer?

Yes, but it’s a teeny-tiny fraction of a percent. Take a look at this handy calculator. Let’s say the temperature is 16 degrees Fahrenheit and a gallon of diesel weighs 7.1 pounds. When the temperature is 106 degrees Fahrenheit, a gallon of diesel fuel weighs 6.8 pounds. Now set the temperature to 69 degrees Fahrenheit, which is a very pleasant temperature. The weight of a gallon of diesel fuel is 6.9 pounds. See? All of the differences are minor. Consider the following scenario: Depending on the size of the fuel tank, the temperature weight differential of diesel fuel will never be more than 10-50 pounds.

## What is the weight of one gallon of gasoline?

This is a question that everyone, whether a seasoned boater or a complete novice, must answer.

A US gallon of gas weighs 6.1 pounds, but an Imperial gallon weighs 7.2 pounds, according to the Science and Technology Desk Reference.

Here are a few things to bear in mind to get a better picture of how much that is:

1. One gallon of petrol weighs less than one gallon of water.

Water weighs 8.4 pounds in comparison to gas. That’s a difference of more than 2 pounds, which explains why gas floats on water. This is why dousing a gasoline fire with water is ineffective.

2. Diesel weighs far more than gasoline.

The weight of a gallon of fuel is about 7.1 pounds. The larger molecules and higher density account for the 1 pound difference. It also has a much higher flash point and autoignition temperatures.

Most boats above 45 feet run only on diesel, which is why the engines are typically larger and heavier.

Imagine these simple examples to make it much easier to measure:

## Does diesel weigh more than gas?

We’ve also witnessed the opposite: one of our clients put gasoline directly into one of his tractor’s diesel fuel tanks by accident. He wanted to know whether there would be any issues.

If you work in the fuel industry long enough, you’ll come across a situation like this at some point. Mixing gasoline with diesel is never a good idea, but it isn’t always a disaster. The most important factor is how much of each you unintentionally added. If that happens to you, here’s what you may expect.

### Big Differences between gasoline and diesel fuel

When attempting to foresee what problems might occur if one fuel is mistakenly mixed with the other, you must consider the most significant distinctions between the two fuels.

Because diesel fuel is made up of big molecules, it is heavier than gasoline. Because of the difference in density and viscosity, it atomizes differently. It also has a much greater flash point and autoignition temperature. And, given these, the inverse can be applied as well. Gasoline is lighter than diesel and flashes at a lower temperature.

When you bring in fuel that isn’t supposed to be there, these variations in physical qualities cause difficulties in engines and fuel systems.

## Is a gallon of gas the same as a gallon of milk?

One of the issues in shifting away from fossil fuels, I often remind people, is that the quantity of energy they hold is actually astounding. A gallon of fuel has enough power to propel a modern automobile for more than 30 kilometers. Consider putting your car in neutral and pushing it for 30 miles; the quantity of energy required is nearly equal to the amount supplied by that gallon of gasoline. A gallon of gas, on the other hand, weighs only six pounds and costs, on average, \$2 to \$3 in the United States, less than a gallon of milk. This is very miraculous.

But why does a gallon of petroleum, a nonrenewable resource that has taken millions of years to develop, requires considerable processing, and is frequently shipped halfway around the world, cost less than a gallon of milk, which is typically produced locally by renewable cows fed renewable grass? The price disparity isn’t just due to the worldwide oil price fall that started in late 2014. For the majority of the last decade, the average price of a gallon of gasoline has been less than the price of a gallon of milk, according to the Consumer Price Index of the United States Bureau of Labor Statistics.

In March 2016, the average price of a gallon of gasoline was \$2.02, less than a dollar less than the average price of a gallon of milk, which was \$3.19. Organic milk may be available for as little as \$7 per gallon in some regions of the country. Let’s take a look at how milk and gasoline are manufactured, stored, and finally delivered to consumers to see what’s behind the price difference.

Crude oil is a mixture of various hydrocarbons that has formed naturally over millions of years and is retrieved from the ground by drilling rigs. The majority of the crude oil produced in the United States is produced in Alaska, North Dakota, Texas, and the Gulf of Mexico. What isn’t made in the US is imported, primarily from Canada and the Middle East.

Crude oil may be held in enormous tank farms for months after it is produced before being piped to a refinery, where it is superheated into a vapor and then distilled from a gaseous mixture of hydrocarbons into constituent fuels like gasoline, diesel, and jet fuel. These liquid fuels are piped from the refinery to terminals, where they are stored in tanks until they are loaded into gasoline tankers and supplied to petrol stations or wherever they are needed. The overall time it takes from oil well extraction to gas pump use is determined by the availability of oil output, refinery capacity, and consumer demand. Crude oil typically takes weeks to months to travel from the wellhead to your gas tank.

Milk begins as a raw liquid that must be processed into a consumer-grade product, similar to gasoline. More than 60,000 dairy farms in the United States generate roughly 57.5 million gallons of raw milk each day, or about 21 billion gallons per year.

Milk is kept at cool temperatures from the moment it exits the cow since it spoils quickly. Before being picked up by a milk truck, raw milk is gathered in storage tanks or silos on the farm and kept below 39 degrees Fahrenheit for no more than 48 hours. Raw milk is then sent to a processing facility, where it is pasteurized, homogenized, sorted into different fat levels, and finally packaged into jugs and cartons for delivery to grocery shops.

All of this takes place in a controlled environment with continual monitoring to guarantee that the milk meets consumer safety standards. The entire process takes about two days, from extraction through pasteurization and packaging to delivery to the grocery store. Because delays in processing and distribution reduce the shelf life of the product, the time from cow to carton is minimal.

This brings us to one of the key reasons milk costs more than gasoline: it is perishable and must be processed and used promptly.

Because milk must be chilled, it cannot be transported through pipeline, which is by far the most efficient method of transporting liquid products over large distances. Milk must be transported in well-insulated tankers or refrigerated trucks instead. Pipelines, on the other hand, are widely used to transport oil across the country. Furthermore, milk cannot be stored for lengthy periods of time, which helps control the market’s supply and demand balance, whereas oil can be stored in large tank farms for months at a time. Cushing, Okla., for example, has a tank farm that can hold up to 80 million barrels of crude oil, enough to produce more than 1.5 billion gallons of gasoline.

The distribution of milk in individually packaged cartons and jugs is another price-relevant difference between milk and gasoline. Because the average American family consumes only a gallon or two of milk per week, the large-scale pumps and tanks used for gasoline are unnecessary. Instead, buying milk in gallon or half-gallon increments is more convenient, and the packaging for each jug and carton adds to the overall cost per gallon. Additionally, because total milk consumption is lower than gasoline use, manufacturers benefit less from economies of scale and must charge more per gallon to pay fixed and overhead costs.

The price of bottled water versus tap water is an illustration of how much transportation and packaging changes may effect cost. According to the International Bottled Water Association, the average price per gallon of bottled water in 2014 was \$1.20, whereas the price of tap water was around \$2 per thousand gallons  or 0.2 cents per gallon, according to the US Environmental Protection Agency. While some of the higher expenses of bottled water are due to filtration and marketing, the majority of the difference stems from the fact that bottled water is individually packaged and carried by truck or train rather than pipeline. Of course, piping milk like water is impossible because we eat so little and milk must be refrigerated, but if we could have a tap for milk in our home fed by municipal pipelines, it would definitely be a lot cheaper than pre-packaged milk.

To be sure, some of the price discrepancies between milk and gasoline are due to factors other than how they are produced and supplied. Milk and oil prices, for example, are influenced by a plethora of rules and subsidies. The basic disparities between milk and gasoline, however, such as shelf life and production, distribution, and consumption scales, are what cause a gallon of milk to cost more than a gallon of fuel.

## What happens if I put a gallon of diesel in my car?

The fuel pump will struggle to transfer the diesel/gasoline mixture through the system since diesel fuel is thicker and denser than gasoline. Additionally, the diesel will be unable to pass through the fuel filter easily. It will instead clog the fuel filter. And any diesel that makes its way into the engine will block the fuel injectors, rendering them useless. The engine will clog up and seize as a result of this. The gasoline engine may continue to run after the diesel tank has been filled, but this is only because it is still running on the residual gasoline in the fuel line.

Even if the circumstance is unpleasant, the alternative  putting gasoline into a diesel tank  is even worse. Because of its enormous combustion potential, gasoline would ignite more faster than diesel fuel. The diesel engine and its components could suffer catastrophic damage as a result of the early ignition and volatility.
