Formula

#
Core Formula
Consumption=Hours×Rate (L/hr)×Load %100\text{Consumption} = \text{Hours} \times \text{Rate (L/hr)} \times \frac{\text{Load \%}}{100}

How it works: Calculates total fuel used by multiplying running time by the consumption rate, adjusted for actual load.

Worked Example

A generator consuming 5L/hr running for 10 hours at 80% load uses 40L of diesel.

Understanding Diesel Consumption

Diesel engines are efficient but their consumption varies based on mechanical load and runtime.

  • Always check the manufacturer data sheet for the base consumption rate.
  • Load factor is often the most overlooked variable in fuel budgeting.
  • Regular maintenance can improve fuel efficiency by up to 10%.

Monitor your consumption to identify potential engine issues early.

You can also calculate changes using our Fuel Cost Increase Calculator or Generator Running Cost Calculator.

Frequently Asked Questions

What is a typical diesel consumption rate?

It varies by engine size; small generators might use 2-5L/hr, while large industrial ones can use over 50L/hr.

Does load affect consumption significantly?

Yes, running at 50% load uses significantly less fuel than 100% load.
