What to do when you’ve put the wrong fuel in your car!

1. Park and turn the car off!

Regardless of whether you’ve put petrol in a diesel car, diesel in a petrol car or the wrong grade of petrol in your car, don’t drive it home. If you’ve driven your car for a few minutes or out from the pump—it’s not the end of the world but try not to drive any further than you absolutely have to.

Ideally, leave your car off and give us a call. But if you have to, turn the car on for just long enough to drive it into a parking bay and away from the bowser.

Driving it for a very short distance, or running it for the few minutes it takes to move it shouldn’t cause long term damage. But if you try and drive the car home, or think “she’ll be right”, you could be in for some seriously hefty repair bills at the mechanic.

2. Give us a call, and tell us what happened.

We see this every day, it’s literally what we do! If you’ve filled up with the wrong fuel, and don’t know what to do or how bad it is—just call us, we’re friendly, experienced and have been in your shoes before!

We can let you know exactly what the safe limits of wrong fuel are, and what you should do if you’re outside these limits. You’ve got options, so let’s have a quick chat and go through them.

3. Assess your options.

If you’ve put the wrong fuel in your car, your options are going to be a little different based on what fuel you’ve put in your car, and which fuel you were supposed to put in.

Petrol in a Diesel Car

Probably the worst scenario (sorry if this one’s you), is petrol in a diesel. It’s not something to take lightly and can have pretty serious consequences if you’re not careful.

If you’ve put petrol in a diesel car, here’s what to do.

Diesel in a Petrol Car

Generally it’s pretty hard to get diesel into a petrol car because the diesel nozzle is physically too large for most petrol spouts. This is a deliberate manufacturing choice to prevent this kind of mix up, but if you’ve managed to get petrol in there—it’s not the end of the world.

If it’s only a small amount of diesel, generally speaking you should be ok. Please don’t take that to mean we think you should ignore it. Diesel will cause your car to run smoky, and can cause premature fouling of components, which can cost you money in needing to replace things like spark plugs, fuel injectors and clog your exhaust system.

91RON in a 98RON only car

Putting the wrong grade of petrol in your car can actually be a pretty big issue. Many late model cars are specifically designed to run on higher grades of petrol, and trying to operate them on lower grades can cause issues. You might notice your car won’t run properly, with a shaky idle or strange noises (pinging and knocking) from the engine itself.

There are solutions to this, such as adding an octane-booster to your fuel tank. In many situations, it’s not advisable to run a late model performance car on the wrong petrol, the strain caused by the poorer grade fuel can cause long term damage. Premature wear to components is also a concern, something that might cost you big time at your next service.

4. Get your fuel sorted

Assuming you’re not game to risk your car by driving it with the wrong fuel, and have decided to make the (right) decision to replace the wrong fuel with the right fuel, then you’ve got a couple of options.

You could get your whole car towed to a nearby workshop—assuming they’re still open—and have them drain your fuel tank and flush the system. But you’ll likely find that not only is this inconvenient, but also more expensive than option 2.

Option 2 is giving Fuel Swap a call. If you’re in the Perth metro area, we can get out to you in generally less time than it would take to get your car towed to the mechanic. We’ll also be able to sort out your predicament on the spot, and get you back on your way without a drama for less than the mechanics would charge.

Wrong fuel sounds like a huge issue, but thankfully the fix is simple. We’ll come out with our specialty tools and license to mess around with hazardous liquids, pump the wrong fuel out of your car, flush the lines and get the right fuel in.

Fuel Swap exists to give you the confidence to get back on the road, knowing your car’s got the right fuel and the wrong stuff has been correctly removed. Know your car has been treated correctly, your warranty is still valid and you’re not going to find yourself trying to find thousands of dollars for a new engine.
