How to Improve Fuel Efficiency: Strategies for Australian Fleet Managers

October 14, 2026

Fuel costs continue to place significant pressure on Australian fleet operators. Rising fuel prices are no longer just a budgeting issue, they’re a direct threat to operational stability. Fuel costs and shortages have put pressure on 72% of Australian businesses, according to new data released by the Australian Bureau of Statistics (ABS).

This situation makes fuel efficiency not just a nice-to-have, but a strategic imperative for staying profitable. This guide shows fleet managers a few strategies and solutions to improve fuel efficiency, no matter the size of your fleet.

Fuel Saving Tips: Driver Behaviour and Training

Driver behaviour alone can impact fuel consumption by up to 30%, making it the one of the most influential factor in your fleet’s efficiency. Aggressive driving – rapid acceleration, hard braking, and speeding – can lower fuel economy at highway speeds and in stop-and-go traffic.

The encouraging news? Drivers who receive regular feedback on their habits tend to improve fuel economy when fuel saving is explicitly targeted. This is about providing actionable insights that help drivers understand how their behaviour affects overall fuel efficiency.

Implementing a structured driver training program to focus on:

  • Smooth acceleration and braking: Avoiding sudden spikes in engine load.
  • Speed management: Maintaining optimal cruising speeds for specific vehicle classes.
  • Idling reduction: Turning off engines during loading, deliveries, or prolonged stops.
  • Proper gear selection: Utilising cruise control and engine braking effectively.
  • Smart route selection: Planning trips around peak traffic congestion periods.

Technology Solutions & Data Analytics for Fleet Fuel Efficiency

Modern fleet management relies on digital data tools to pinpoint and eliminate fuel waste. Even without complex hardware, businesses leverage software solutions – such as online management portals, smart fuel card data, and mobile navigation apps to achieve measurable reductions in operating costs.

Key digital technology solutions for optimising fleet fuel efficiency include:

  • Automated Data Reporting: Digital fuel management platforms consolidate fill-up frequency, volume (litres), location, and spend across your entire fleet, making it simple to spot unusual consumption spikes.
  • Driver Location & Navigation Apps: Equipping drivers with digital locator tools minimizes unnecessary detour kilometres when searching for preferred, cost-effective fuel stops.

Smarter Navigation with the WEX Motorpass Driver App
Digital tools directly support smarter daily navigation. Through the WEX Motorpass Driver App, drivers quickly locate over 6,500 participating service stations and EV charging hubs across Australia – saving both travel time and fuel on the road.

Vehicle Maintenance and Fuel Saving

Regular maintenance directly impacts fuel consumption, though the effects often go unnoticed until they accumulate. 

Essential fleet vehicle maintenance tasks for fuel efficiency include:

  • Tyre pressure checks: Under-inflated tyres increase rolling resistance and accelerate tread wear.
  • Engine tune-ups & oil changes: Always use manufacturer-recommended oil grades to reduce internal engine friction.
  • Air filter replacements: Clogged filters restrict airflow, forcing the engine to burn extra fuel.
  • Wheel alignment: Proper alignment reduces drag and keeps vehicle tracking true.
  • Prompt diagnostic fixes: Address check engine lights and diagnostic fault codes immediately.

Creating a Culture of Fuel Efficiency

Technology and maintenance can only take you so far. Sustainable fuel efficiency practices require cultural changes across your organisation. Drivers need to understand not just what to do, but why it matters. When team members see how their individual efforts contribute to company success – and when fuel efficiency is recognised and rewarded – behavioural changes become permanent.

Here’s how you can get started:

  • Start by establishing baseline metrics for each vehicle type in your fleet
  • Share regular updates with drivers showing their performance 
  • Recognise top performers publicly 
  • Provide additional coaching for those struggling with efficiency targets
  • Build motivation to encourage better driving behaviour

Fuel Saving Strategies by Fleet Types

Implementing the right fuel-saving strategies for your fleet business depends on your fleet size and operations. Here are a few fuel efficiency strategies to consider for different fleet types.

Large Fleets

Large fleets benefit from economies of scale in technology adoption and data analysis. With hundreds of vehicles, even a 1% improvement in fuel efficiency can generate tens of thousands of dollars in annual savings.

Large fleets should prioritise:

  • Dedicated fuel management personnel who analyse trends and implement improvements
  • Standardised vehicle specifications to simplify maintenance and training
  • Bulk fuel purchasing agreements to reduce per-litre costs
  • Regular benchmarking against industry standards

Small Fleets

Small fleet managers face unique productivity challenges. Without dedicated fleet management staff, owners often juggle multiple responsibilities, making it difficult to implement systematic fuel efficiency programs. Many small fleets lack formal fuelling policies, leading to cash discrepancies and unforeseen expenses.

For smaller operations, focus on:

  • Fuel cards with built-in reporting and controls 
  • Driver scorecards that highlight fuel efficiency alongside safety metrics
  • Preventative maintenance schedules that prevent costly breakdowns
  • Route optimisation tools that reduce unnecessary kilometres

WEX Motorpass offers fuel card solutions for both small business and large fleets, making it easier to manage fuel efficiency across different levels of fuel expenditure.

Mixed Fleets

To improve fuel saving in mixed fleets, the key is segmentation. Track and set realistic efficiency targets based on vehicle type, typical loads, and routes. What constitutes excellent efficiency for a diesel truck would be entirely different for an EV, so avoid one-size-fits-all approaches – energy consumption per kilometre and cost-per-kilometre should be benchmarked within each vehicle type, not across them.

Fuel Cards: A Practical Solution for Fuel Management

One of the most straightforward ways to improve fuel efficiency tracking and management is implementing a dedicated fuel card program. Fleet fuel cards provide fleet managers with comprehensive tools to monitor, control, and optimise fuel spending across all vehicle types.

WEX Motorpass fuel card solutions offer real-time transaction monitoring, detailed reporting on fuel consumption by vehicle and driver, and the ability to set spending limits and restrictions. You’ll immediately identify anomalies – whether that’s excessive consumption, unauthorised purchases, or inefficient vehicles that need attention.

The data generated by WEX Motorpass integrates with your broader fleet management strategy, providing the visibility needed to make informed decisions about vehicle replacement, driver training needs, and route optimisation opportunities. WEX Motorpass ​​​​is the only multi-brand fuel card in Australia to offer a digital payment experience for electric vehicles, making it the practical choice for businesses transitioning to EVs.
