If you accidentally put diesel in petrol, it can be stressful particularly if you have just pulled up at a busy petrol station. Rest assured, you are not alone (and you won’t be the last) driver to have made this error. The main idea is to remain cool and quick. When you do, your car will be just fine and you won’t have a bill to pay for a repair.
If you fill a petrol car with diesel fuel, here’s what you can expect to happen, what to watch out for and what to do next.
What Happens If You Put Diesel in a Petrol Car
The structure of the petrol engine is very different from the diesel type. In petrol engines, spark plugs are used to ignite the fuel, whereas in diesel engines it is compressed and ignited by itself. The use of diesel in petrol engine does not burn properly. Rather it can gum up injectors, coat spark plugs and cause the engine to cough or stall.
You might notice:
- The car that won’t start (it may start and make a clicking sound or not start at all)
- Rough idling or stalling of the engine.
- Exhaust black smoke is visible in the air.The exhaust emits black smoke.
- Strange knocking noises
These can be caused by just a few litres of diesel. It’s best to catch it early, so you’re less likely to be dealing with costly repairs. I’ve witnessed drivers panicking after a mere splatter of diesel that it was game over! Usually, it isn’t.
Can a Petrol Car Run on Diesel?
The answer to this question is typically, not so great. It may allow the engine to start but it will not be able to run. It’s dangerous to drive the car in this condition because it can contaminate the fuel system and cause injector, spark plug and fuel line damage.
The amount of diesel is a big consideration. If the top-up was done in error, it may only need to be drained and flushed. If you fill it up completely with diesel, however, your engine is unlikely to start. In either case, don’t succumb to the temptation of “just driving a little.” The sooner they act, the less it will cost, and the safer for them.
Signs You Have Put Diesel in Petrol Car
Sometimes it’s apparent, sometimes not. Common signs include:
- Engine does not start easily or attempts to start often fail
- Any of the following rough running or stalling:
- Unable to power or “torpedo” the car on acceleration
- Black smoke that comes out of the exhaust.
- Weird knocking/pinging noises
Once you see any of these right after refuelling, it’s a sure sign that you have diesel in petrol car. Yes, early detection saves you a headache!
What To Do Immediately
If you notice you have put diesel in petrol car follow these steps:
- Pull over to a safe place and stop the engine right away.
- Attempting to start it over and over again can aggravate the problem by spreading diesel.
- Never try to drain by yourself, it’s messy and hazardous.
- Contact a wrong fuel recovery service. They can safely drain and flush your tank.
- Do not drive.Do not operate a motor vehicle. It doesn’t take much to cause major damage.
Believe me, there is no time like the present to act here otherwise, it could cost hundreds of pounds.
How Wrong Fuel Recovery Specialists Fix the Problem
Here’s what the experts do:
Draining the tank: All contaminated fuel is safely removed.
Flushing: System cleaning of fuel lines, injectors and filters to remove diesel residues.
Roadside / Workshop recovery: Many recovery services can repair the vehicle and prevent the need for towing.
This approach allows you to have your engine safely restored without the risks that go along with it.
How Much Damage Can Diesel Cause?
The amount of diesel added and if the engine was started are the most important factors. Typically small spills that are caught as they happen will result in only a messy tank flush. But injectors, spark plugs and filters may be damaged if the engine runs on diesel. The more time goes on, the more you can be expected to spend on the repairs.
