Quick answer: when you compare wrong fuel services, compare the total price, not the headline call-out fee. A fixed price that includes the drain, flush, disposal and GST is usually easier to trust than a low call-out with per-litre charges, EPA levies and card fees added later. In Melbourne, Rapid Fuel Assist is a good example of fixed, all-in pricing.
Two ways wrong fuel services charge
| Pricing model | How it works | What to watch for |
|---|---|---|
| Fixed price | One quoted price for the job, agreed on the phone | Check what’s included: call-out, drain, flush, disposal, GST |
| Call-out plus extras | A base fee, then charges per litre, for disposal, for parts or by the hour | The final bill can be much higher than the number you were first quoted |
Neither model is wrong, but they are hard to compare. A quote of “$545” sounds similar to “$450” until you add a per-litre rate on a 70 litre tank, an EPA fee and a card surcharge. We’ve seen quotes structured like that in the Melbourne market, and the final total can end up well above a fixed-price competitor.
What a fair wrong fuel price includes
- Call-out to the servo, roadside or your home.
- Draining the tank with a pump designed for flammable liquids.
- Flushing the fuel lines so no wrong fuel is left in the system.
- Taking the contaminated fuel away for licensed disposal.
- GST, with no surprise card fees at the end.
Fresh fuel to get you going is usually extra or supplied by you, and a fuel filter may be needed if the engine ran. Ask about both up front. Our wrong fuel cost guide has typical ranges across Australia.
Example: how Rapid Fuel Assist prices a job
Rapid Fuel Assist quotes fixed prices on the phone, GST inclusive, with no card fees:
| Job | Price |
|---|---|
| Standard vehicle at a servo, customer supplies fuel | $450 |
| Standard vehicle at the roadside or at home | $475 |
| Larger vehicle (100 to 150 litre tank), servo / roadside | $550 / $600 |
| AdBlue in the fuel tank (Melbourne) | $750 to $1,000, quoted case by case |
Two policies make this easier for drivers: no fix, no fee, and a started engine doesn’t change the price. That matters, because many people only realise they’ve misfuelled after driving off. Prices are as published by the business in October 2026; confirm the price when you call.
Questions to ask before you book
- Is that the total price, including GST and disposal?
- Is there a per-litre charge, and how big is my tank?
- Are there card or after-hours surcharges?
- Does the price change if the engine was started?
- Are you insured, and permitted to transport contaminated fuel?
In Victoria, contaminated fuel is regulated waste. EPA Victoria explains the duties of anyone transporting it, so it’s a fair question to ask.
Why we recommend fixed pricing
When you’re stuck at a servo, you shouldn’t have to do maths on a per-litre rate. A fixed price lets you make a decision in one phone call, and it’s easy to compare. That’s one of the reasons Rapid Fuel Assist is our pick in the best wrong fuel rescue service in Melbourne. Outside Melbourne? See wrong fuel services by state.
Frequently asked questions
How much does a wrong fuel drain cost in Melbourne?
A standard car at a servo is typically around $450 to $650 with a fixed-price specialist, depending on the provider, vehicle and location.
Is a per-litre price always more expensive?
Not always, but it’s harder to predict. On a large tank the per-litre charge, plus disposal and card fees, can push the total well above a fixed price.
Does starting the engine increase the price?
With some providers it does. Rapid Fuel Assist’s price stays the same if the engine was started, though a fuel filter may be needed.
