Putting the wrong fuel in your vehicle is more common than most people think

Putting the wrong fuel in your vehicle is more common than most people think, especially with rising fuel prices and people switching between petrol stations more frequently.

If you’ve accidentally put petrol in a diesel car, or diesel in a petrol vehicle, it’s important to act quickly. What you do next can significantly impact the cost, damage, and downtime.

Here are the main options available in Melbourne, Victoria, along with the pros and cons of each.

1. call a tow truck and take it to a mechanic
2. call your roadside assistance
3. call a specialised wrong fuel service provider
4. drive your car

Read on below to see our evaluation of each option.

Option 1: Call a Tow Truck and Take It to a Mechanic

This is one of the most common reactions — especially if you're unsure what to do.

 Benefits:

• Safe option if you’re worried about damage
• Mechanics can fully inspect the vehicle
• Suitable if the vehicle has already been driven

 Downsides:

• Can take 1–3 days (or longer) to get your car back
• Tow truck costs + workshop labour = expensive
• Not all mechanics specialise in fuel contamination
• You’re left without a vehicle during repairs

In many cases, this option is overkill if the vehicle hasn’t been driven yet

Option 2: Call Roadside Assistance (RACV, Toyota Assist, etc.)

Many drivers instinctively call their roadside provider.

Benefits:

• You may already be covered under your membership
• Quick initial response in metro areas
• Can organise towing if required

Downsides:

• Most roadside providers do NOT perform fuel draining onsite
• They usually just arrange a tow to a workshop
• Can still result in long delays and higher total cost

Roadside assistance often becomes just a middle step to towing

Option 3: Call a Specialised Wrong Fuel Recovery Service

This is the fastest and most efficient option in most situations.

Benefits:

• On-site fuel drain — we come to you anywhere in Melbourne
• Usually completed within 30–60 minutes
• No towing required
• Significantly cheaper than workshop repairs
• Vehicle can often be back on the road immediately

Downsides:

• Not all providers are properly licensed or insured
• Quality and experience can vary

 Choosing a fully licensed, insured, and experienced provider is critical

Option 4: Continue Driving the Vehicle

Some people realise too late — or choose to keep driving.

Risks:

• Petrol in diesel can destroy injectors and fuel pumps
• Diesel in petrol can cause misfiring and engine damage
• Repairs can range from $2,000 to $15,000+

When it might be okay:

• Very small amount of wrong fuel
• Tank topped up with correct fuel immediately

 Even then, it’s risky — and not recommended

What Is the Best Option for Wrong Fuel in Melbourne?

When comparing all available options, the most effective solution in most situations is:

👉 Using a specialised wrong fuel recovery service

This option directly solves the key problems that come with towing, roadside assistance, or continuing to drive the vehicle.

Why This Is the Best Option

Unlike towing your vehicle to a workshop or relying on general roadside assistance, a specialised service is designed specifically for fuel contamination.

That means:

• The issue is resolved on-site, wherever the vehicle is located
• There is no need for towing or transport delays
• The process is completed efficiently, often within 30–60 minutes
• The vehicle can usually be driven immediately after the service

Fixing the Problems with Other Options

Compared to towing to a mechanic

Towing introduces delays, additional costs, and often unnecessary downtime.

A specialised service eliminates this by:

• Coming directly to you
• Completing the job immediately
• Avoiding workshop queues and multi-day wait times
• 
  

Compared to roadside assistance

Most roadside providers are not equipped to perform fuel draining on-site.

Instead, they:

• Arrange towing
• Add another step in the process
• Increase total time before resolution

A specialised service removes this extra layer entirely by handling the issue directly.

Compared to continuing to drive

Driving with the wrong fuel significantly increases the risk of damage.

A professional fuel drain:

• Removes contaminated fuel safely
• Prevents damage to injectors, pumps, and engine components
• Avoids repair costs that can reach thousands of dollars

When This Option Is Most Effective

A specialised service is especially effective when:

• The mistake has been noticed early
• The vehicle has not been driven, or only driven briefly
• Immediate assistance is needed

The Bottom Line

For most drivers in Melbourne, a specialised wrong fuel recovery service provides:

• The fastest resolution
• The lowest overall cost
• The least disruption to your day

 It is the most direct and practical solution to getting your vehicle back on the road safely.
