Weight regulations for trucks
The weight of diesel fuel is about 7 pounds per gallon in the US and a little more, around 7.1 pounds, in Canada. This means 70 gallons of diesel fuel weighs around 490 pounds.
The weight of a truck's fuel can impact everything from fuel costs to axle weight distribution and route planning. In the trucking industry, every pound matters, especially when managing a fleet of heavy-duty vehicles that travel across different states.
Each state in the US has its own unique regulations regarding legal weight limits for trucks. These regulations are based on the state's infrastructure and what the roads can safely support. While the federal government sets safety guidelines, including the maximum weight-to-length ratio, it does not regulate heavy haul or overweight shipments. Instead, each state is responsible for issuing permits for overweight loads, which may include bridge reviews to ensure the infrastructure can support the weight.
The weight regulations vary for single-axle, double-axle, and tri-axle trucks, with limits in place to preserve road quality and ensure safety. Trucks with a gross vehicle weight (GVW) of 80,000 pounds or more are considered overweight and may require special permits to operate, depending on the state. Even if a truck meets legal requirements, some states may still require a permit if the load is particularly heavy.
To ensure compliance with weight regulations, truckers can use fuel gauges, regularly stop at weigh stations, and utilise telematics systems to monitor fuel levels and consumption. Proper weight distribution within a truck can also reduce wear and tear on tires and suspension.

How to calculate diesel weight
To calculate the weight of diesel fuel, you can use the fact that the density of diesel is approximately 0.85 pounds per gallon, which means that each gallon of diesel fuel weighs about 7.1 pounds (0.85 pounds/gallon * 8.34 pounds/gallon). So, to find out how much 70 gallons of diesel fuel weighs, you can multiply 70 by 7.1, which gives you approximately 497 pounds.
Now, this calculation assumes that the diesel fuel has a standard composition and is at a specific temperature. The density of diesel can vary slightly depending on factors such as the particular mixture of hydrocarbons in the fuel and the temperature at which it is measured. For instance, diesel fuel generally becomes slightly denser as temperatures decrease. So, the weight of diesel fuel can change depending on these variables, but the variation is usually quite small and not significant for most practical purposes.
If you need to be extremely precise, you can take into account the density variation with temperature. Diesel fuel is often quoted as having a density of 0.85 kg/L at 20 degrees Celsius. This is the standard temperature for density measurements. The density can vary by about 0.001 kg/L for every degree Celsius away from this standard temperature. So, if you know the temperature of the diesel fuel in Celsius, you can adjust the density figure accordingly and then convert to pounds per gallon if needed.
Additionally, it's worth noting that diesel fuel sold at gas stations is usually a blend of diesel fuel and biodiesel, which can have a slightly different density than pure diesel fuel. Biodiesel is typically made from vegetable oils or animal fats and has a higher density than diesel fuel, so a higher biodiesel blend percentage will result in a slightly heavier fuel. However, this difference is often negligible for most calculations unless a very high percentage of biodiesel is used.
In any case, for most everyday purposes, you can simply use the rule of thumb that diesel fuel weighs about 7.1 pounds per gallon, and multiply this by the number of gallons you have to get a quick and reasonably accurate estimate of the weight of diesel fuel.
So, for 70 gallons, we estimate:
1 pounds/gallon * 70 gallons = 497 pounds
Thus, 70 gallons of diesel fuel weighs approximately 497 pounds, give or take a few pounds depending on temperature and blend specifics.
