Typically 5 to 10 litres, enough to reach the next open station. Most vehicles cover 10 to 20 km on 5 litres depending on engine and load. London Tow Truck confirms the closest open station and matches the drop-off amount to the drive distance.

Fuel Tank Empty? London Mobile Fuel Delivery Arrives in 30–55 Minutes
Gauge reads zero on Highway 401, a rural connector, or a back road in Strathroy, Woodstock, Ingersoll or st. Thomas. London Tow Truck sends a mobile fuel technician with gasoline, diesel or DEF to get you rolling again.
- Gas, diesel and DEF in stock
- Technician on-scene diagnostics
- Roadside pour and crank
Quick Roadside Fix
Empty Tank Rescue, 5–10 Litres Poured On-Scene in Under 20 Minutes
A fuel delivery call is one of the fastest roadside fixes. The technician pulls up with 5 to 10 litres of the right fuel, pours it into the tank, and the engine starts. Most vehicles are back on the road in fifteen to twenty minutes. The amount is calibrated to reach the next open station, typically ten to twenty kilometres depending on engine size and driving conditions.
Diesel vehicles and RVs introduce a second fluid: DEF (Diesel Exhaust Fluid). Modern Cummins, Duramax and Powerstroke engines use DEF in a separate tank to meet emissions standards. When DEF runs low, the engine derates or won't start at all. The technician confirms which tank is empty before pouring. London roadside assistance covers both fuel and DEF. If the no-start persists after fuel is added, the call can shift to London wrecker service or 24/7 emergency towing.
Fuel Delivery Walkthrough
How Mobile Fuel Service Works, Step by Step
-
Call with location and fuel type
Share your kilometre marker or street address, vehicle make, and whether you need gasoline, diesel or DEF. Confirm you're safely off the traffic lane with hazards on.
-
Technician rolls with the right tank
Mobile fuel rig arrives with 5 to 10 litres of the matching fuel and the correct adapter for your filler neck.
-
Fuel poured and engine started
Technician pours the fuel, replaces the cap and attempts a crank. If the engine won't turn over, basic diagnostics run on the shoulder.
-
Navigate to the next station
Technician confirms the closest open fuel station and the drive distance. Fill up to a full tank as soon as you arrive.
Highway Gaps
Why Drivers Run Dry, Long Fuel Gaps on London-Area Corridors
London sits at the intersection of major highway corridors with significant fuel gaps. Highway 401, Highway 402, Highway 4, Highway 2 and rural connectors can run twenty to sixty kilometres between open stations, especially on weekends and late nights when smaller stations close. A driver who misjudges the gauge or hits unexpected traffic can easily run dry before the next pump.
Winter driving makes the problem worse. Cold-weather engines burn more fuel during warm-up, and idling on a shoulder consumes litres quickly. A gauge that read half-full on a warm morning may be nearly empty after a cold night. Diesel pickups and RVs add another layer: DEF consumption depends on engine load and emissions system design. London heavy-duty towing handles mechanical failures, while RV towing covers larger rigs. Check London service area coverage to see which routes have the longest gaps.

London Fuel Delivery FAQ
How much fuel arrives, what fluids are carried, no-cell stranding plans, DEF versus diesel and what happens if a no-start persists after fuel.
Yes. Mobile fuel rigs carry regular 87 octane gasoline, diesel and DEF (Diesel Exhaust Fluid) for 2009-and-newer SCR diesels. Specify the fuel type when calling so the right tank is on the rig. Premium octane and pre-mix two-stroke are available with extra notice.
Move to a safe location off the traffic lane, then walk toward higher ground or a visible service road to find signal. On rural highway corridors signal usually returns within a kilometre or two of major intersections. Once a call goes through, share the kilometre marker, the closest landmark and the direction of travel.
No. DEF is a 32.5 percent urea solution sprayed into the exhaust stream to reduce emissions. It rides in its own tank, separate from diesel. When DEF runs out, modern diesels limit speed or refuse to start. London Tow Truck technicians carry DEF in 2.5-litre containers and top the reservoir to a safe operating level.
The technician runs basic no-start diagnostics, spark, fuel pressure, crank response. If the issue is a bad pump, clogged filter or air-locked rail, the phone operator can pivot to a flatbed tow to a repair shop. Pricing for fuel delivery typically runs $80 to $150 in Ontario with a $20 to $50 after-hours surcharge between 10 PM and 6 AM, and the operator confirms the rate before the rig rolls.
