Propane, having a chemical formula of C3H8, also known as LPG, is widely used in many commercial applications such as powering industrial forklifts because it has low vapor pressure making this gas ideal to be compressed into the liquid inside a cylinder at room temperature.
But what kind of propane do forklifts use? To give a straight answer to this, HD-5 is the kind if propane gas that is used by propane-powered tools and heavy equipment such as a forklift. HD-5 is suitable to power forklifts because of its mixture of a minimum of 90% propane and a maximum of 5% propylene. In that mixture, propylene doesn’t gum up inside the IC engine during combustion.
HD-5, being a widely used grade of propane, at least in the US, is readily available for commercial purposes because 90% of the gas in the market is domestically produced. In fact, 48 million households and businesses used this grade for various applications – that includes fuel forklifts. If you order propane tanks from your local dealer, if you ask what grade of propane they offer, they would gladly say it is HD-5.
Other advantages making propane ideal for power forklifts are friendly to the environment as it burns it generates low greenhouse gas emissions, the gas is non-toxic making the equipment suitable even for indoor use and the gas is cheaper than gasoline or diesel.

Where to Buy HD-5 Grade Propane for Your Forklift Operation Needs
Before you dial a nearby dealer in your location, it is better to contact National Propane Gas Association to get a referral from a reputable supplier. The association maintains a listing of reputable companies in every state, just give them your zip code, and they then provide the closest propane dealer in your area.
Another way to get recommendations from friends or colleagues – they definitely can give honest feedback about the company they’re getting their propane from. Though, online company reviews is available to make a decision, we would not suggest relying on such reviews since data can be altered.
The demand for HD-5 propane is on the rise, with the increased use in homes and commercial and industrial settings, you would expect its price to go up as well.
What are the Advantages of Propane-Powered Forklifts?
Propane-powered forklifts are a powerful and efficient choice for any business owner looking for an alternative to gasoline and diesel-powered forklifts. This kind of forklift has many advantages over other types of trucks:
- Cost-effective – propane offers better fuel efficiency and is much cheaper as well compared to their diesel and gasoline counterparts, which means business owners like you can save a lot of money on their fueling costs significantly.
- Less strain for the operator – forklifts that run on propane produce much less vibration while running and cause less strain on the operator’s back and body during long periods of use.
- Environmentally-friendly – propane is a clean burning fuel, which means that it produces fewer emissions than the other fuels mentioned above.
- Easy to handle – propane gas is easier to handle than gasoline or diesel fuel because it doesn’t need a station in the workplace for refueling as those fuels do. Since this is contained in a cylinder, it is more portable to handle.
- Produces more or exactly the same power compared to other fuel types – the forklift engine is internal combustion, which burns fuel to produce power. Propane is flammable, has a 105 octane rating, just like its counterparts, and produces the same power to run the vehicle and to lift heavy loads even on an incline.
- Clean-burning – propane, having just a maximum of 5% propylene, a chemical to use plastic, burns cleanly and produces fewer deposits that could gum up inside the IC engine. This ultimately leads to a longer-running engine.
Why Do Forklifts Use Propane as Fuel?
There are two main reasons for this: portability and ease of use. Since propane is contained in cylinders, making the handling of these tanks portable; refueling is a breeze as well since a worker can simply grab a filled tank and swap it with the empty one.
Propane doesn’t produce toxic gases, unlike diesel or gasoline where carbon monoxide can accumulate. With that being said, propane-powered forklifts are ideal for indoor use in warehouse and storage companies.
Propane is cheaper compared to other counterpart fossil fuels; a 33-lb propane tank with 7.8 gallons of liquid can be used by the forklift for an eight-hour operation straight, while in gas or diesel-powered truck having the same amount of liquid, can only be used for 5-6 hours of operation.
How Long Can a Forklift Run on a Single Tank of Propane?
If you’re wondering how long a forklift can run on a single tank of propane, the answer may surprise you. A standard 33-pound tank of propane can last up to 7-8 hours on a forklift, depending on the model and usage.
Of course, this is just an estimate, as there are many factors that can affect how long a tank of propane will last. The size of the tank is one factor, as is the weight of the load being lifted. A forklift that’s lifting heavy loads all day will obviously use more propane than one that’s only being used for light tasks. The terrain can also affect propane usage, as a forklift going up and down hills will use more fuel than one travelling on level ground.
Despite these factors, 8 hours is still a pretty good estimate for how long a full tank of propane will last a forklift. So if you’re worried about running out of fuel in the middle of a shift, you can rest assured knowing that your forklift will likely be able to make it through an entire day on a single tank.
About 90% of forklifts use an eight gallon tank of liquid propane
An eight gallon tank of liquid propane will last most forklifts about eight hours of use. That tank size is 33 pounds and is the most common size used in forklifts.
This size tank is typically enough to power the forklift for several hours. However, it is important to note that the amount of time that the forklift can run on a single tank of propane will vary depending on how the machine is being used. For example, if the machine is being used to lift heavy loads, it will use more propane than if it was being used to move lighter loads. It is also worth noting that propane is not the only type of fuel that can be used in forklifts. Other common options include gasoline and diesel. However, propane is generally considered to be the best option for most applications.
Causes propane-powered Forklifts to Use More Propane Than Normal
There are several reasons why propane-powered forklifts may use more propane than normal. One reason is that the engine may not be tuned properly. This can cause the engine to run hotter than normal, which can lead to increased fuel consumption. Another reason is that the forklift may be overloaded. This can also cause the engine to run hotter than normal and lead to increased fuel consumption. Finally, if the forklift is used in a dusty environment, the air filter may become clogged, which can restrict airflow to the engine and cause it to run hotter than normal, leading to increased fuel consumption.
To Make a Conclusion
So you’re driving a forklift and you’re wondering what kind of propane it uses? The grade is HD-5 propane. With its wide availability in the market, its popular use for home and industrial applications such as for fueling forklifts.
