Fuel Swap FAQ
Frequently Asked Questions
What should I do if I accidentally put petrol in my diesel car?
Turn off the engine immediately and do not attempt to drive the vehicle. Contact Fuel Swap — we provide rapid fuel drain services across Perth with minimal downtime.
Can I drive my car after misfuelling?
No. Driving a vehicle with the wrong fuel can severely damage the fuel system. Fuel Swap’s technician can remove the contaminated fuel safely to help you avoid costly repairs.
How much petrol in diesel is too much?
Anything above 2 litres of petrol in a diesel tank is considered unsafe and should be removed. Even small amounts can damage modern diesel fuel systems. Fuel Swap provides fast, expert draining to prevent long-term damage.
I put 5 litres of petrol in my diesel car — will it be okay?
5 litres is well above the recommended safety threshold. Anything over 2 litres should be professionally drained to avoid costly fuel system repairs. Fuel Swap can resolve it quickly on-site.
Is it bad to start a diesel car after putting in petrol?
Yes. Starting the engine circulates the petrol through the system, increasing the risk of damage. If you’ve started the vehicle, call Fuel Swap immediately.
How quickly can you come to me?
We offer the fastest response times in Perth, with technicians on standby most hours of the day. Fuel Swap is built for emergency misfuels — you won’t wait long.
What areas do you service?
We service all of Perth — including Joondalup, Rockingham, Fremantle, Midland, and more. If you’re in the metro area, we’ve got you covered but we also service much of the surrounding area too usually up to 75kms from the CBD with amazing response times.
Do you service outside of Perth?
We service up to 75km from Perth’s CBD as standard. In special circumstances, we may travel as far as 150km — just give us a call and we’ll do our best to assist.
Do you offer 24-hour fuel drain services?
No. We operate most hours and try our best to be on-call as much as possible covering across the Perth metro and regional areas. Day or night, we’re available but are only capable of so much.
What makes Fuel Swap different?
Fuel Swap is run by Australia’s most experienced fuel drain technician, with over 6,000 services personally performed. We provide the fastest, safest, and most cost-effective solution in the country.
Do you handle both petrol in diesel and diesel in petrol situations?
Absolutely. Whether it’s petrol in diesel, diesel in petrol, or AdBlue in the wrong tank — we’ve seen it all.
Will I need a tow truck?
No — in 99% of cases, we can resolve everything onsite without towing. We drain, flush, and refuel your vehicle so you can drive away.
How long does the service take?
Most jobs are completed within 30 to 45 minutes. We prioritise speed without compromising safety.
Is Fuel Swap insured?
Yes — we carry full public liability and professional indemnity insurance for peace of mind.
Can I claim this on insurance?
In many cases, no — depending on your policy. We can provide an invoice and report for an attempt to claim if needed but generally advise against it as most policies have a minimum excess of $500 similar to the service price but without upping future premiums from making a claim.
Is there a call-out fee?
Our pricing is competitive and transparent. While card fees and other surcharges may apply, we always provide a clear cost breakdown before we begin. Fuel Swap remains the most affordable option in Perth. Call us to go over your pricing options.
Do you offer fleet or business services?
Yes — we regularly service company fleets and commercial vehicles and are suppliers of Australia’s largest novated leasing companies. Ask us about our business partnerships and volume pricing.
Can you help with motorbikes, trucks, or machinery?
Absolutely. We’ve successfully drained everything from motorcycles to excavators and tractors. If it runs on fuel, we can fix it.
Do you use safe equipment?
Yes — our system is designed for zero contamination and complete vehicle safety. No cutting hoses or damaging components.
How do I know if I’ve put in the wrong fuel?
Common signs include knocking, smoke, trouble starting, or dashboard errors. If you suspect misfuelling, don’t risk it — call us.
I drove my diesel car after putting petrol — what now?
Even if you’ve already driven it, we can help. Damage risk increases the longer it’s running, so call Fuel Swap immediately.
Can you fix unleaded in diesel?
Yes. Petrol (unleaded) in diesel is our most common job. Our equipment removes it safely and quickly.
Are you the same as Fuel Fix / Wrong Fuel Rescue?
No — Fuel Swap is an independent, Perth-based operation run by Australia’s most experienced fuel drain technician. We do not subcontract our work to undertrained or third-party operators. When you book with us, you get the best — Fuel Swap guarantees a qualified, expert technician on every job.
Do you come to me?
Yes — we are 100% mobile. Whether you’re at home, work, a servo or stranded roadside, we come to you.
