Ask any mobile food operator what keeps their business cooking and the answer is fuel. Propane for food trucks is the quiet workhorse behind every griddle sear, fryer basket, and burner flame at a busy BC summer market. It is portable, powerful, and independent of the grid, which is exactly what a kitchen on wheels needs when it parks at a festival in Cloverdale one weekend and a brewery lot in Langley the next. The same fuel runs the commercial ranges and water heaters in many brick-and-mortar restaurants across the Fraser Valley, especially those off the natural-gas grid.
This guide covers how mobile and commercial kitchens actually use propane, how to size cylinders so you never run dry mid-service, the difference between refill and exchange, and the safety rules that keep you compliant. Whether you run a single truck or a small restaurant group, getting the fuel side right protects both your service and your margins.
Why Propane for Food Trucks Is the Industry Standard
Electric simply cannot match gas for live-fire cooking on a mobile rig. A food truck needs instant, high-output heat that responds the moment a cook turns a valve, and it needs that heat without a shore-power hookup at every stop. Propane for food trucks delivers exactly that: a flat-top hits temperature fast, a fryer recovers quickly between baskets, and a six-burner range runs all of it at once without tripping a breaker. Because propane is stored on board, the truck is fully self-contained and can serve a remote campground, a film set, or a festival field with no infrastructure at all.
It is also cost-effective. Propane carries a high energy density per dollar, burns clean, and produces predictable results that a chef can dial in. For operators feeding hundreds of guests in a single shift, that reliability is the whole game.
What Propane Powers in a Mobile Kitchen
On a typical truck or trailer, propane runs nearly every hot appliance:
- Griddles and flat-tops for burgers, smash patties, breakfast service, and stir-fry.
- Deep fryers, which are heavy fuel users and the first appliance to suffer when a cylinder runs low.
- Open burners and ranges for sauces, boils, woks, and sauté work.
- Charbroilers and grills for that live-flame char customers can taste.
- Ovens and proofers in baking-focused trucks.
- On-demand water heaters for the hand-wash and three-compartment sinks your health permit requires.
That last point matters: many operators forget the water heater is also on propane, so the fuel budget has to cover sanitation, not just cooking. Run out of gas and you do not just stop cooking, you fall out of health compliance.
Cylinder Sizes and How Long They Last
Most food trucks run one or two refillable cylinders, commonly in the 30 lb to 100 lb range, mounted in a vented, secured rack. Sizing depends on appliance load and service length:
- 20–30 lb cylinders suit small carts, coffee trailers, and light single-appliance setups.
- 40–60 lb cylinders handle a mid-size truck with a griddle and a fryer through a normal market day.
- 100 lb cylinders are the go-to for high-volume trucks running multiple heavy appliances across long festival weekends.
The honest answer to “how long will it last” is that it depends on how hard you cook. A fryer and a flat-top going hard for an eight-hour festival can drain a small bottle faster than a new operator expects. The safe move is to carry more capacity than a single shift needs, and to track usage so refills are planned, not panicked. Our guide to small propane tank sizes breaks down the common cylinders in detail.
Refill or Exchange: Keeping the Truck Running
Two models keep a mobile kitchen fuelled, and most operators use a mix:
- Refill means your own cylinders get filled by volume at a depot or by a delivery service. You pay for exactly the litres you take, which is the cheaper per-litre option and the better choice for high-volume trucks.
- Exchange means swapping an empty for a full one. It is fast and convenient when you are mid-route, but you pay a premium for the convenience and sometimes get a tank with less than a full charge.
For a busy operation, scheduled refills keep costs down, while keeping a spare exchange option in your back pocket covers the emergency mid-service swap. The same logic applies to forklifts and other propane equipment, which is why many operators lean on a propane cylinder exchange and refill service that can do both.
Beyond the Truck: Commercial Kitchens on Propane
Plenty of restaurants, catering kitchens, and food-production sites in the Fraser Valley run on propane rather than piped natural gas, either because they sit off the grid or because they want the cooking performance of a high-BTU gas line they control. These operations move from cylinders to larger stationary tanks with scheduled bulk delivery, so the kitchen never interrupts service to chase fuel. If you run a catering company or a rural restaurant, the principles are the same as a food truck, just at a larger volume, and a delivery partner can right-size a tank to your actual load. Reliable propane delivery across the Fraser Valley is what keeps those kitchens open.
Safety and Regulations You Cannot Skip
Propane in a food-service setting is tightly regulated, and for good reason. In British Columbia, gas systems and appliances fall under Technical Safety BC, which means your installation generally needs a licensed gas fitter, properly rated hoses and regulators, and appliances certified for commercial use. Cylinders must be secured upright in a ventilated compartment, away from the cooking area, with the right clearances.
Festivals and public events add another layer: organizers and fire officials often require proof of a current fire-safety inspection, a working extinguisher rated for grease and gas fires, and documentation before they let a truck plug into the lineup. The Canadian Propane Association publishes handling guidance worth knowing as well. The takeaway is simple: build the system to code, keep your inspection paperwork current, and partner with a fuel supplier that understands food-service requirements rather than treating you like a backyard barbecue.
What Drives Your Propane Costs
Fuel is a real line item for a food business, and a few factors move it:
- Appliance load — fryers and charbroilers burn far more than a single burner.
- Service hours — long festival days multiply consumption fast.
- Refill vs exchange — refilling by volume almost always beats exchange on price.
- Delivery vs depot — scheduled on-site delivery saves labour and downtime, especially for multi-truck operators.
- Season — winter pricing runs higher across the board, though most truck demand peaks in summer.
Fuelling a Busy Festival Season
Summer is when mobile kitchens make their money, and it is also when fuel logistics get hardest. A truck might work a farmers market on Saturday morning, a brewery event Saturday night, and a multi-day festival the following weekend, all without returning to a home base in between. Running out of propane for food trucks at the peak of a Saturday rush is not just lost sales, it can mean falling out of health compliance the moment the hand-wash water heater goes cold.
The operators who get through festival season cleanly plan their fuel like they plan their menu. They carry more cylinder capacity than a single event needs, they know which sites allow a fuel delivery and which do not, and they build a relationship with a supplier who can refill on a schedule or meet them on a route. For a multi-truck operation, having cylinders topped up at the commissary before the weekend, rather than scrambling at a depot mid-event, is the difference between a smooth season and a stressful one. The busier your calendar, the more a reliable refill and delivery partner pays for itself.
Frequently Asked Questions
How much propane does a food truck use per day?
It varies widely with appliance load and hours. A light single-appliance cart might sip from a 20 lb bottle, while a busy truck running a fryer and flat-top through a festival weekend can burn through a 100 lb cylinder or more. Track your own usage over a few services to set a reliable refill schedule.
Is refilling cheaper than exchanging cylinders?
Almost always, yes. Refilling charges you by the litre for a full fill, while exchange builds in a convenience premium and sometimes delivers a partially filled tank. High-volume operators save meaningfully by refilling and keeping exchange as a backup.
Do I need a licensed gas fitter for my food truck?
In BC, propane systems and commercial appliances are regulated by Technical Safety BC, and installation or modification generally requires a licensed gas fitter plus certified components. Always confirm current requirements for your build and keep your inspection records on hand for event organizers.
Can you deliver propane to my truck or commissary?
Yes. We refill and deliver across the Fraser Valley and Greater Vancouver, so multi-truck operators and commissary kitchens can keep cylinders topped up on a schedule instead of running depot errands during prep.
