The situation can be stressful if you put diesel in petrol, particularly when you discover it at the petrol station. Fortunately, this is typically not as serious as filling a diesel vehicle with petrol. Nevertheless, it is still advisable to move quickly.
The key word is “do not start the engine. When the car is started, the wrong fuel is circulated through the fuel system. This can increase the chance of problems and make the recovery more complicated.
Mr Fuel Doctor offers professional wrong fuel recovery services and mobile fuel drain services. Our techs can come to you and extract contaminated fuel but don’t need to make the trip to your garage.
What Does Diesel in Petrol Mean?
Petrol and diesel are the same except that the latter is accidentally introduced in a petrol-powered vehicle.
This is less likely to occur because the nozzle of the diesel pump is usually bigger than the petrol filler opening. It is still possible, however. For instance you could fill up at a different pump, drive the wrong car, or use a fuel can when you were meant to use a pump.
While diesel is not as harmful as petrol in a diesel engine, it still requires care.
Diesel is more viscous and heavier than petrol. In a petrol engine, the ignition system needs to be able to start a fire in the petrol. Diesel is not combustible in the same manner. Thus, the fuel system can become contaminated, causing poor running conditions for the engine.
What Should You Do After Putting Diesel in a Petrol Car?
First, stay calm. Don’t assume that if you’ve made a fuel error your engine is destroyed.
Follow these steps:
1. Do Not Start the Engine
This is the most crucial step.
If you notice the mistake before starting your car, leave the engine switched off. Never try to turn the key as a test to see if the vehicle starts.
It may be possible to circulate the fuel system with the diesel engine starting. This can complicate the recovery process. Ford also cautions drivers against starting a car after mixing up the gasoline.
2. Walk away safely from the pump.
If your car is blocking a petrol station pump, advise the station attendants.
Gently shift to neutral and transport to a safe area if safe and feasible. Don’t run it away from the station.
3. Visit a Fuel Drain Specialist
After you are safe, have professional fuel removal services.
A mobile fuel drain technician will be able to pump the contaminated fuel from the fuel tank and clean up the remaining fuel in the system. This can save you the hassle of having to call a tow truck to your garage.
Mobile wrong fuel recovery services available throughout the UK, call Mr Fuel Doctor for his services to be dispatched to roadside, home and forecourt locations.
What Happens If You Start the Car With Diesel in It?
If you have already begun your petrol car, do not begin to panic.
Turn off the engine when it is safe to do so. If you are in a car, pull over safely, not in a hazardous place.
After getting into the engine, diesel can cause a number of symptoms. These can include:
- Engine misfiring
- Rough running
- Excessive exhaust smoke
- Poor acceleration
- Engine cutting out
- Difficulty restarting
- Engine failure to restart.
The symptoms are in line with advice given by the main motoring bodies and car manufacturers.
If the vehicle continues to run on contaminated fuel, more fuel will circulate through the system the longer it is run. Thus, the best solution is to obtain help as soon as possible.
Diesel in Petrol Symptoms to Look Out For
Not all cars will exhibit the same symptoms. But diesel in petrol symptoms include the following:
Engine Misfire
Engine may run unsteady or vibrate during operation. This can give the impression that the car is having trouble to maintain normal combustion.
Excessive Smoke
Avoidable smoke from the exhaust may be observed. This occurs when the diesel is not combusting inside a petrol engine.
Loss of Performance
When accelerating the car may feel slow. May be unable to respond when pressing the accelerator.
Engine Cutting Out
If a vehicle becomes contaminated with diesel fuel, it could still be driven for a short distance before stopping.
Difficulty Starting
After contaminating the fuel enters the fuel system, the engine may be slow to start or may not start at all.
If you experience these symptoms after refueling, discontinue driving at a safe time and get professional help.
Is Diesel in Petrol Worse Than Petrol in Diesel?
Generally, no.
The most often serious misfuelling error is to put petrol in a diesel car. A diesel fuel system utilizes diesel fuel to provide important lubrication to certain components of the system. Petrol can decrease that lubrication and enhance the risk of damage when the engine is operating.
However, diesel running in a petrol car can cause issues. But it is usually the combustion problem or contamination of the fuel system that is the problem.
But don’t ignore it. If you think you are not having trouble with your car’s fuel, it should be handled properly anyway.
