7 Tips to Improve the Fuel Economy of Your Diesel Engine

Beachwheels Automotive – Diesel Specialists in Brookvale, Manly & the Northern Beaches

Diesel engines are known for their efficiency and longevity — but like any vehicle, they perform best with the right maintenance and driving habits. Whether you’re managing a work ute, 4WD, or a heavy-duty vehicle around Brookvale, Manly, or the Northern Beaches, improving your fuel economy can save you money and reduce your environmental impact. Here are 7 practical tips to help you get the most out of every tank.

1. Keep Up with Regular Servicing

Sticking to your diesel engine’s service schedule is key. Old oil, clogged filters, and worn-out parts can reduce fuel efficiency. At Beachwheels Automotive, our diesel servicing includes injector cleaning, filter replacement, and performance checks to keep your engine running efficiently.

2. Check Your Tyre Pressure

Under-inflated tyres increase rolling resistance, making your engine work harder. This directly affects fuel economy. Make sure your tyres are inflated to the correct PSI — especially if you’re towing or carrying heavy loads. We offer vehicle inspections that include tyre pressure checks and adjustments.

3. Drive Smoothly, Avoid Heavy Acceleration

Rapid acceleration burns more diesel. Try to accelerate steadily and use cruise control on highways when possible. Smooth driving not only saves fuel but also reduces wear on your engine and brakes.

4. Reduce Idle Time

Diesel engines use surprisingly large amounts of fuel when idling. If you’re stopped for more than a minute or two, it’s more efficient to switch off the engine — especially in warmer months where the air con works harder.

5. Use the Right Engine Oil

Using the correct grade of diesel engine oil reduces friction and ensures the engine operates at peak performance. Not sure what oil your vehicle needs? Our mechanics in Brookvale and Manly can recommend the right product for your engine.

6. Lighten Your Load

Carrying unnecessary weight places extra strain on the engine. Remove roof racks when not in use, and clear out heavy tools or cargo you don’t need for day-to-day driving.

7. Upgrade Your Driving Habits

Planning routes to avoid stop-start traffic, combining errands into one trip, and keeping your speed in check all contribute to better fuel economy over time.

Bonus Tip: Book a Diesel Engine Tune-Up

A professional tune-up can boost power and improve fuel economy. We’ll check your fuel injectors, turbo, filters, and more to ensure your diesel engine is running efficiently and cleanly.
