You're not the first. Diesel in a petrol happens every day.
We'll talk you through what to do, right now on the phone.
We come to you: servo, home, work or roadside.
One call and we handle everything. Most diesel in petrol jobs are done in under two hours, start to finish.
Tell us your vehicle type and where you are.
Quick ETA confirmation, usually within the hour.
Drain, flush the lines, refill with the right fuel.
Running cleanly, report emailed, you drive away.
What happens, what we do, and why most cars are fine after a clean recovery.
A petrol engine ignites fuel with a spark, not by compression like a diesel does. Splash diesel into a petrol tank and the engine simply can't burn it cleanly. You get poor running, heavy smoke, fouled plugs and, on modern direct injection engines, the wrong viscosity going through fuel injectors that weren't designed for it. It's less destructive than the reverse mix up, but it's still a job for a technician, not for hoping the next tank dilutes it.
Like petrol in a diesel, the priority is to stop the contaminated fuel reaching the engine. If you haven't driven on it, the diesel is sitting in the tank and the recovery is straightforward, drain, flush, refuel. If you have driven and noticed misfiring, smoke or rough idle, pull over safely and switch the engine off. The further you drive, the more the system needs cleaning, but it almost never crosses into engine damage territory the way petrol in diesel can.
We come to you wherever it happened, at the servo, at home, at work or on the roadside. A qualified technician safely drains the contaminated fuel, flushes the lines, refills with the correct fuel and checks the car runs cleanly before you leave. No tow truck, no workshop visit, no guesswork.
If your tank has stale fuel or water in it too, that becomes contaminated fuel removal and disposal, same rig on our end. And if you're reading this at the pump, here's what to do at the bowser right now.
Diesel in a petrol car happens less often than the other way round, but it happens plenty. Different mistake, different cars. We see it on Camry, Corolla, RAV4, Mazda 3, i30, Cerato, Yaris, Swift, Golf, Polo, and the family SUVs, Kluger, X-Trail, Outlander, CX-5. Usually it's a work ute driver who's grabbed the diesel nozzle out of habit, but the car they took today is the wife's Corolla.
Call us before you start the car. We come to you, drain the tank, flush the system and put fresh unleaded back in. Servo forecourt, driveway, side of the road, doesn't matter where you are. We handle the mess and the disposal, you just drive off.
If you cranked it or drove a bit before you realised, still fixable on the spot, just takes a bit longer. Diesel doesn't vaporise at petrol cylinder temperatures, so unburnt slug goes past the rings and into the exhaust. Foul plugs, hot cat, that kind of thing. Not the end of the world in most cases, but the earlier you stop the less flushing we have to do.
The reason diesel in a petrol happens the other way around from what you'd expect: the petrol nozzle is thinner than the diesel one, so it drops straight into a petrol filler no problem. But if you're used to filling up the ute at a truck servo, muscle memory can put a diesel handle in the wrong car. If you've done it, stop there. Don't start the car. Call (08) 7083 9699. We'll come to you.
Straight answers about diesel in a petrol car. If yours is not here, call and ask.
Every car's a bit different. Some we drain straight from the fuel cap, some we need to get underneath, some have the tank in an awkward spot and we work around it. Doesn't really matter to you, we've done enough of them to know what we're walking into before we get there.
Yes, but not the same way as petrol in a diesel. Diesel doesn't vaporise at petrol cylinder temperatures, so an unburnt slug of it can foul the spark plugs and overheat the cat if you drive on it. Not the end of the world, and most cars come right after a proper drain and refuel. Big picture, stop as soon as you notice and call us.
Do not start the engine. Do not turn the key. Push the car clear of the pump if you can safely, then call (08) 7083 9699. We answer 24/7 and dispatch straight away. Typically inside the hour across Adelaide metro, actual ETA quoted on the call.
From $400 for metro Adelaide callouts. Diesel in petrol jobs often come in at the base rate because volumes and drive distances tend to be smaller than the reverse. You hear the exact number on the phone before we dispatch, no fix no fee, and a written invoice on site.
Full Adelaide metro, the Hills, Barossa, Fleurieu Peninsula and Victor Harbor. Metro response typically inside the hour, Hills and Barossa 60 to 90 minutes, Fleurieu 90 to 120 minutes. Actual ETA quoted on the call. Same operator, same van, same phone number no matter where you are.
We drain the tank, flush the system and put fresh petrol in. Then we run a full system scan, listen to the engine, and only hand the keys back once it's running like it should. You get a full comprehensive report on the job and a written invoice on the spot.
Not a great plan. Diesel in a petrol tank causes rough running, fouled plugs and, if you drive on it long enough, an overheated cat. That said, most cars we see for this are still fine after a proper drain and refuel. Stop as soon as you notice, call us, we'll go from there.
Not as fast as people think. If you've noticed and pulled over quickly, most cars are absolutely fine after a proper drain, flush and running check. Damage risk goes up the further you drive under load, so the earlier you stop the better. If you've already driven a distance, mention it on the call, we plan the running check accordingly.
Most comprehensive policies cover a wrong fuel misfill, either as accidental damage or a specific wrong fuel benefit. We give you a plain English invoice with EPA Licence 52359, service type and time on site, which is what insurers ask for.
