Running out of diesel is different from running out of gasoline. Diesel engines power commercial trucks, construction equipment, backup generators, refrigerated trailers, and an increasing number of passenger vehicles across the GTA. When a diesel vehicle runs dry, you cannot just walk to the nearest gas station with a jerry can — diesel nozzles do not fit standard portable fuel containers at most retail pumps, and misfuelling with gasoline will destroy a diesel engine.
That is where emergency diesel fuel delivery comes in. This guide covers who needs diesel delivery, what the service costs in Toronto, how it works, what happens if you put the wrong fuel in, and where to find diesel fuel delivery near you across the Greater Toronto Area.

How Emergency Diesel Fuel Delivery Works
The process is straightforward — whether you are stranded on the 401 at 2 AM or need a generator refuelled at a condo building during a power outage:
Call and provide your details
Tell us your exact location, vehicle type, and confirm that you need diesel (not gasoline). If you are on a highway, give us the direction of travel and nearest exit or landmark.
We dispatch the nearest driver
Our network covers the entire GTA. The closest available unit is dispatched with diesel fuel in approved, DOT-compliant containers.
Fuel is delivered and dispensed
Our technician delivers enough diesel to get you to the nearest fuel station or, for generators and equipment, enough to keep operations running until your regular supply arrives.
You are back up and running
Modern diesel engines may need the fuel system primed after running completely dry. Our team can assist with priming if needed so the engine starts on the first try.
💡 Diesel engine tip: When a diesel engine runs completely out of fuel, air enters the fuel lines and injection system. Most modern diesels have a self-priming pump that bleeds the air automatically after refuelling — just cycle the ignition key to “ON” (without starting) 3–4 times, waiting 10 seconds each time. Older diesels may require manual bleeding at the fuel filter. Our drivers are trained in both procedures.
How Much Does Diesel Fuel Delivery Cost in Toronto?
Emergency diesel delivery costs include a service call fee plus the cost of the fuel itself. Here is what you can expect in the GTA:
Some commercial roadside assistance plans (through fleet insurance or truck manufacturers) include fuel delivery at no extra charge. Always check your policy before paying out of pocket. For a full breakdown of towing and roadside costs, see our towing cost Toronto price guide.

What Happens If You Put Gasoline in a Diesel Engine?
⚠️ CRITICAL: Never Put Gasoline in a Diesel Engine
Putting gasoline in a diesel engine is one of the most expensive fuelling mistakes you can make. Gasoline acts as a solvent inside a diesel fuel system — it strips the lubricating properties that diesel provides, causing metal-on-metal contact in the high-pressure fuel pump and injectors. If the engine is started on contaminated fuel, the damage can be catastrophic and repairs can cost $5,000 to $15,000+ for a new fuel pump, injectors, and fuel lines.
If you accidentally put gasoline in your diesel vehicle, take these steps immediately:
Do NOT start the engine. If you have not turned the key, the contaminated fuel is only in the tank. This is recoverable.
Do NOT try to “dilute” it by adding more diesel on top. This does not fix the problem.
Call for a tow. The vehicle must be towed to a mechanic who can drain the tank and flush the fuel system. Call Towing Toronto for a flatbed tow.
If you already started the engine, turn it off immediately and call for a tow. The longer a diesel engine runs on gasoline, the more damage is done.
A tank drain and fuel system flush typically costs $500 to $1,500 — expensive, but far cheaper than replacing the entire fuel injection system. This is a key reason to always verify fuel type before filling up, and to call for professional diesel delivery rather than attempting to source fuel yourself when stranded.
Diesel vs. Gasoline: Why the Right Fuel Matters
It may seem obvious, but many misfuelling incidents happen when someone borrows a car, uses an unfamiliar rental, or fills up at a busy station without checking the pump label. Here is a quick comparison:
Notice that a gasoline nozzle is smaller than a diesel filler neck, which means it can physically fit into a diesel tank. This is how misfuelling happens most often — someone accidentally puts the smaller gas nozzle into a diesel vehicle. The reverse (diesel into a gas car) is much less common because the diesel nozzle is too large to fit most gasoline filler necks. Natural Resources Canada provides additional guidance on fuel types and efficiency.
Winter Diesel Challenges in Toronto
Toronto winters create unique problems for diesel vehicles that gasoline vehicles do not face. Diesel fuel can gel — thicken and form waxy crystals — in extremely cold temperatures, clogging fuel filters and preventing the engine from starting.
Cloud point (–10°C to –15°C): Wax crystals begin to form in untreated diesel. Fuel appears cloudy but still flows.
Pour point (–20°C to –30°C): Fuel thickens to the point where it will not flow through lines and filters. Engine will not start.
Winter diesel blend: Canadian fuel suppliers switch to a winter-grade diesel (often blended with kerosene or anti-gel additives) from roughly November to March. Always fuel up at major stations during winter to ensure you are getting treated diesel.
Block heater tip: If your diesel truck sits overnight in Toronto’s cold, plug in the block heater. A warm engine block keeps the fuel in the lines warm enough to prevent gelling. Most diesel trucks sold in Canada come with a block heater installed from the factory.
If your diesel vehicle will not start on a cold Toronto morning due to gelled fuel, do not keep cranking the starter — you will drain the battery without solving the problem. Call for roadside assistance to either deliver treated diesel or tow the vehicle to a warm shop where the fuel can thaw. The Ontario Ministry of Transportation recommends keeping diesel tanks above half-full in winter to reduce condensation and gelling risk. See our Toronto winter driving safety tips for more cold-weather guidance.
5 Tips to Avoid Running Out of Diesel
Never let the tank drop below a quarter. Running a diesel tank very low draws sediment from the bottom of the tank into the fuel filter, which can clog the system and cause stalling — even if there is still fuel in the tank.
Know where diesel pumps are on your route. Not every gas station in the GTA sells diesel, especially smaller neighbourhood stations. Map out stations with diesel along your regular routes.
Use a fuel-finding app. Apps like GasBuddy show which stations near you sell diesel and their current prices. Filter by fuel type before heading out.
Replace fuel filters on schedule. A clogged fuel filter makes the engine run less efficiently and can cause stalling even with a half-full tank. Follow your manufacturer’s replacement interval. For more maintenance reminders, check our spring car maintenance checklist.
For fleets: schedule regular on-site fuelling. Commercial diesel delivery services in Ontario (like Alpha Oil, Roma Fuels, and Brown’s Fuels) offer scheduled on-site fleet fuelling so your trucks start every morning with a full tank.

Frequently Asked Questions About Diesel Fuel Delivery
Is diesel fuel delivery available 24/7 in Toronto?
Yes. Towing Toronto provides emergency diesel fuel delivery 24 hours a day, 7 days a week, 365 days a year — including holidays, weekends, and overnight. After-hours surcharges may apply between 10 PM and 6 AM.
How much diesel will be delivered?
Emergency roadside delivery typically provides enough fuel to get you to the nearest diesel station — usually 10 to 20 litres. For generators and commercial equipment, larger volumes can be arranged. Let the dispatcher know your needs when you call.
How much does emergency diesel delivery cost?
Emergency diesel fuel delivery in the GTA typically costs $75 to $150 including the service call and fuel. After-hours, highway, and large-volume deliveries may cost more. The fuel itself is priced at a premium over the pump price to cover transport and convenience.
What happens if I put gasoline in my diesel truck?
Do not start the engine. Gasoline strips the lubricating properties that diesel fuel provides, causing severe damage to the high-pressure fuel pump and injectors. Call for a flatbed tow to a mechanic for a fuel tank drain and system flush. If you already started the engine, turn it off immediately — the damage worsens the longer it runs.
Can you deliver diesel to a generator or construction site?
Emergency diesel delivery to generators and equipment can be arranged through Towing Toronto. For regular scheduled refuelling of generators or construction equipment, dedicated commercial fuel suppliers in the GTA such as Alpha Oil, Roma Fuels, and Brown’s Fuels offer scheduled on-site delivery with bulk pricing.
My diesel truck will not start in the cold — is it out of fuel or gelled?
If the tank is not empty, the fuel may have gelled due to extreme cold. Diesel gels when wax crystals form and clog the fuel filter, which can happen at temperatures below –15°C with untreated fuel. Do not keep cranking the starter — you will drain the battery. Call for roadside assistance to have the vehicle towed to a warm shop or to deliver anti-gel treatment.
Why will my diesel engine not start after running out of fuel?
When a diesel engine runs completely dry, air enters the fuel lines and injection system. Most modern diesels have a self-priming electric pump — cycle the ignition key to the ON position (without cranking) three or four times, waiting about 10 seconds each time, to bleed the air. Older diesels may need manual bleeding at the fuel filter.
Does roadside assistance cover diesel fuel delivery?
Many commercial vehicle insurance policies and fleet roadside programs include fuel delivery coverage. CAA and some consumer roadside plans also cover a limited amount of fuel delivery per year. Check your policy or membership details before paying out of pocket.
What is the difference between clear diesel and red dye diesel?
Clear diesel is standard on-road fuel that includes all applicable road taxes. Red dye (coloured) diesel is tax-exempt fuel intended only for off-road equipment such as construction machinery, farm equipment, and generators. Using red dye diesel in an on-road vehicle is illegal in Ontario and carries heavy fines. Emergency roadside delivery always uses clear, road-legal diesel.
Can I carry a diesel jerry can in my truck as a backup?
Yes, but use a proper yellow-labelled CSA-approved jerry can designated for diesel fuel. Red cans are for gasoline and blue cans are for kerosene. Store the can in a well-ventilated area such as a truck bed — never inside the cab. Keep the can sealed tightly and replace stored diesel every 6 to 12 months, as diesel degrades over time.
