Misfuelled Your Diesel Car?
We Can Help!
CRITICAL: Do Not Start Your Engine!
Misfuelled your diesel? Stop. Don't start the engine. Don't turn the key.
Petrol in a diesel engine strips lubrication from fuel pumps and injectors. Every second of running multiplies the damage.
Already started it? Turn it off immediately and call us now.
What Is Misfuelling & Why Is It So Dangerous?
The Danger of Misfuelling a Diesel
- •Diesel fuel lubricates the high-pressure fuel pump. Petrol destroys this lubrication instantly
- •Metal-on-metal contact causes catastrophic wear to precision injectors
- •Modern common-rail diesel systems are extremely sensitive to fuel contamination
- •Repair costs exceed $5,000-$15,000+ if the engine is started with wrong fuel
- •Even a small amount of petrol (5-10%) is enough to cause serious damage

Misfuelling Symptoms in a Diesel Car
Already started the engine after misfuelling? Watch for these warning signs:
Engine struggles to start or won't turn over
Loud knocking or rattling from the engine
Excessive white or black exhaust smoke
Severe loss of power and acceleration
Engine stalls repeatedly or cuts out
Check engine warning light appears
Strong unusual smell from the exhaust
Rough, uneven idling or vibration
How Much Does It Cost to Fix a Car Misfuelling?
The price to fix a car misfuelling depends on whether you caught the mistake before or after starting the engine. Professional on-site misfuelling recovery — where we drain and flush your system before damage occurs — is a fraction of the cost of engine component repairs.
- Misfuelling caught at the pump (engine not started): Simple drainage. Lowest cost. Call 0416 692 022 for a quote.
- Engine started but not driven: Drainage plus full system flush. Moderate cost. Prevents serious damage.
- Engine started and vehicle driven: Comprehensive drainage, flush, and damage assessment. Still far cheaper than injector/pump replacement.
For comparison: A single diesel injector replacement costs $500-$1,500 per injector. A full set of 4-6 injectors plus a high-pressure fuel pump replacement can exceed $10,000-$15,000 in parts and labour. Professional misfuelling drainage prevents all of this.
Complete Misfuelling Recovery Service
We completely remove contaminated fuel from your diesel system. As Perth's most trusted wrong fuel Perth specialists, our misfuelling recovery prevents engine damage and gets you back on the road safely.
Misfuelling a diesel vehicle is the single most common fuel mistake in Australia. Modern diesel nozzles are the same size as unleaded petrol nozzles, making it easy to grab the wrong one — especially when rushed, distracted, or driving an unfamiliar vehicle.
Why Professional Misfuelling Recovery Matters
DIY siphoning only removes fuel from the tank — contamination has already entered fuel lines, the fuel rail, and the filter. Incomplete removal means residual petrol continues destroying your diesel injection system.
Our professional service uses specialised equipment to drain the tank completely, flush every component of the fuel system, and ensure zero contamination remains before refuelling.
Our Misfuelling Drainage Process
Complete Drainage
We drain 100% of the contaminated fuel from your diesel tank using explosion-proof professional extraction equipment.
System Flush
We flush all fuel lines, the high-pressure pump, fuel rail, and filters to remove every trace of petrol contamination.
Filter Replacement
We inspect and replace the fuel filter to prevent trapped contaminants from re-entering your clean fuel system.
Correct Refuel
We add the correct diesel fuel and test your vehicle to ensure it starts, idles, and drives smoothly before clearing you to go.
Does Insurance Cover Misfuelling?
One of the most common questions after a misfuelling incident: does insurance cover misfuelling? The answer varies by provider and policy type. Here's what you need to know about misfuelling insurance cover in Australia:
- •Standard comprehensive insurance: Most policies do not automatically cover misfuelling. Check your Product Disclosure Statement (PDS).
- •Roadside assistance add-ons: Some breakdown cover does include misfuelling as a covered event. RAC, NRMA, and RACQ offer this in some plans.
- •Does car insurance cover misfuelling? If your policy includes it, you typically pay the excess and the insurer covers the rest. Making a claim may affect future premiums.
- •Is misfuelling covered by insurance? Even without specific coverage, the cost of professional drainage is far less than the repair bill from driving with contaminated fuel.
We Help With Insurance Claims
Regardless of your insurance situation, we provide:
- Detailed, itemised invoice suitable for insurance claims
- Before and after service documentation
- Professional assessment of contamination level
- Written record of work performed and fuel disposed
- Advice on how to file your claim effectively
Many customers find it simpler and more cost-effective to pay directly rather than claim, avoiding excess fees and potential premium increases.
Misfuelling Diesel — Common Questions
What counts as misfuelling a diesel vehicle?
Misfuelling a diesel means putting any incorrect fuel into a diesel tank. The most common mistake is adding petrol (unleaded) to a diesel vehicle. It also includes filling with the wrong grade of diesel, adding AdBlue to the fuel tank instead of the AdBlue tank, or water-contaminated fuel entering the system.
How much does it cost to fix a misfuelling incident?
For accurate pricing on our mobile misfuelling recovery service, call us directly on 0416 692 022. Professional on-site drainage is significantly cheaper than the $5,000-$15,000+ repair bill you face if contaminated fuel damages your high-pressure diesel injection system.
Does insurance cover misfuelling a diesel car?
Most standard comprehensive car insurance policies do not automatically cover misfuelling. Some insurers offer it as an optional add-on or include it in roadside assistance packages. Check your policy or call your insurer. We provide full documentation for insurance claims.
Can I just top up with diesel to dilute the petrol?
No. Even a small percentage of petrol in diesel destroys the lubricating properties that protect your high-pressure fuel pump and injectors. Dilution does not eliminate the damage risk. The only safe option is complete professional drainage and system flush.
How long does a misfuelling recovery service take?
Most jobs take 30-60 minutes on-site. We drain the tank, flush the fuel system, replace the fuel filter if needed, refuel with correct diesel, and test the vehicle. You drive away the same day.
I misfuelled and drove my diesel — is it too late?
Stop driving immediately and call us on 0416 692 022. The sooner you stop, the less damage occurs. We can still drain and flush the system. Some vehicles recover fully even after brief driving, especially if caught early. We will assess the situation on arrival.
How to Prevent Misfuelling Your Diesel
Fit a Misfuelling Prevention Device
Aftermarket diesel fuel cap adapters only accept the larger diesel nozzle, physically preventing a petrol nozzle from fitting into your tank. A one-time purchase that eliminates the risk entirely.
Label Your Fuel Cap Clearly
Place a bright "DIESEL ONLY" sticker next to your fuel cap. This is especially important if multiple people drive the vehicle or you use rental cars frequently.
Focus at the Pump
Avoid distractions — put your phone away, stop conversations, and read the pump label before lifting the nozzle. Most misfuelling happens when drivers are rushed or distracted.
Check the Nozzle Colour
In Australia, diesel nozzles are typically black and petrol nozzles are green. However, this varies by station — always read the label rather than relying on colour alone.
Inform All Drivers
Make sure everyone who drives your vehicle knows it takes diesel. Family members, employees, and friends borrowing your car are the most common source of misfuelling mistakes.
Never Refuel When Exhausted
Fatigue is a leading cause of misfuelling. If you're exhausted after a long drive, take a moment to confirm the correct fuel type before lifting the pump.
Be Extra Careful with Rental Cars
Always check the fuel type label inside the fuel cap when picking up a rental car. Many misfuelling incidents occur when drivers assume the rental takes the same fuel as their own vehicle.
These simple precautions can save you from the stress, cost, and inconvenience of a misfuelling incident. But if it happens, we're here 24/7 to fix it fast.
