When it comes to reliable backup power in Canada’s demanding climate, Diesel Generators remain the top choice for many businesses and households. But one important factor that buyers often overlook is fuel consumption. Understanding how much fuel a generator consumes and what affects this rate can help you save thousands in the long run.
In this blog, we’ll break down everything you need to know about fuel consumption in diesel generators — especially within the Canadian context — and help you make an informed decision before investing in one.
Why Diesel Generators Are Popular in Canada
From British Columbia to Nova Scotia, extreme weather and frequent power outages make diesel fueled generators a practical solution for consistent power supply. Their fuel efficiency, durability, and low maintenance make them ideal for commercial, industrial, and even residential use.
Companies like Caterpillar Generator Company and Cummins Generator Canada have been leading providers for decades, offering high-performance systems that can run smoothly even in freezing Canadian winters.
What Determines Fuel Consumption in Diesel Generators?
Fuel consumption isn’t fixed. It depends on several factors such as:
- Load Capacity: A generator running at 25% load consumes far less fuel than one operating at 75% or full capacity.
- Engine Efficiency: High-efficiency cat engines or Cummins Connect systems burn fuel more effectively.
- Generator Size: A 25kW generator or a 10kW generator will obviously consume less fuel than a 100kW model.
- Maintenance: Poorly maintained units burn more fuel. Always keep your generator enclosure clean and your system well-serviced.
- Age of the Generator: Used generators for sale are cheaper but may not be as fuel-efficient as new models.
Average Fuel Consumption Rates
Let’s talk numbers. On average, a diesel generator consumes:
- 0.4–0.6 litres per kWh at 25% load
- 0.6–0.8 litres per kWh at 50% load
- 0.8–1.0 litres per kWh at 75–100% load
So, if you’re running a diesel generator for sale at 50% load for 10 hours, expect it to use about 50–80 litres of diesel.
How to Reduce Fuel Consumption
If you’re worried about rising fuel prices, you can take steps to reduce your generator’s fuel usage:
- Choose the Right Size: Don’t buy a 100kW generator for a 25kW load. You’ll waste fuel and money.
- Buy Fuel-Efficient Brands: Brands like Cat Generator and Caterpillar Generators are known for their high efficiency.
- Regular Maintenance: Change filters, check oil levels, and inspect the fuel system regularly.
- Avoid Light Loading: Running a generator below 30% load for long periods causes fuel inefficiency and carbon build-up.
- Install ATS: An Automatic Transfer Switch ensures the generator only runs when needed.

Choosing Between New and Used Diesel Generators
A common dilemma is whether to go for a used generator for sale or invest in a brand-new unit. Here’s a quick comparison:
| Feature | New Diesel Generator | Used Diesel Generator |
|---|---|---|
| Initial Cost | High | Low |
| Fuel Efficiency | Excellent | Varies |
| Lifespan | Long | Depends on condition |
| Warranty | Included | Rarely included |
| Availability of Parts | Guaranteed | May be difficult |
Used generators are a great budget option, especially if they come from reputable sellers and include a service history. Make sure to inspect the generator enclosure and performance stats before buying.
Final Thoughts
