Quick answer: a diesel Ford Ranger was filled with petrol at a local servo and driven about 5 km home to Doveton, near Dandenong. We came to the house, drained the tank, flushed the fuel system and refilled it with diesel in the driveway. The price was our fixed $475 for a home or roadside job. No tow truck and no workshop.
Petrol in a diesel ute is one of the most common calls we get in Melbourne’s south-east. If it has happened to you anywhere from Dandenong to Pakenham, stop driving, leave the engine off and call us on 1300 692 469. Here’s how this job went, so you know what to expect.
The Job: Petrol in a Diesel Ranger, Driven Home
On Friday morning, 9 October 2026, we were called to a home in Doveton, in Melbourne’s south-eastern suburbs. The Ranger had been filled with petrol instead of diesel at a local petrol station about 5 km away, and then driven home.
Because the ute was already in the driveway, there was no need to move it. We parked our service ute alongside and did the whole job on site.

Why Petrol Is a Problem in a Diesel Engine
Diesel doesn’t just burn in a diesel engine, it also lubricates the high-pressure fuel pump and the injectors. Petrol is thinner and works more like a solvent, so it strips away that lubrication. The longer a diesel runs on a petrol mix, the more the pump and injectors are put at risk. That’s why the advice is always to stop as soon as you realise. We explain the details in how far you can drive on petrol in a diesel.
A short drive home, like this one, means the petrol has left the tank and is in the fuel lines and filter too. So the fix is more than emptying the tank: the whole fuel system needs to be flushed before fresh diesel goes in. Our petrol in diesel service covers this on site.
How We Fixed It in the Driveway
- Drained all the contaminated fuel out of the tank into our sealed transfer tank.
- Flushed the fuel lines so no petrol was left in the system.
- Refilled with fresh diesel and bled the system.
- Started the Ranger and let it idle to make sure it was running on clean fuel.
The contaminated fuel goes with us. We’re EPA Victoria licensed, so we transport it and dispose of it ourselves at a licensed waste facility. Nothing is left behind at your place.
What It Cost
This job was $475, our fixed price for a standard vehicle at home or at the roadside. If the vehicle is still at the fuel pump, it’s $450. Prices include GST, have no card fees, and are quoted on the phone before we come out. Starting or driving the car doesn’t change the price, and it’s no fix, no fee. More detail is in our 2026 Melbourne price guide.
| Where the vehicle is | Standard vehicle |
|---|---|
| At the fuel pump | $450 |
| At home or roadside | $475 |
Rangers are one of the vehicles we see most. If you want to compare, here’s another Ranger job where a dealership quoted thousands for the same problem.
If It Happens to You
- If you’re still at the pump, don’t start the engine.
- If you’ve driven off, pull over somewhere safe and switch off. Don’t drive it further to get home.
- Don’t top up with diesel to dilute the petrol. It’s still contaminated.
- Note roughly how many litres went in and call us on 1300 692 469.
