Typically occurs quickly. You drive up to the petrol station, pick up the nozzle without a second thought and then it hits you. The wrong one. Don’t worry if you have diesel in petrol. Unfortunately, this error occurs more often than it should in the UK, and in many instances the error can be corrected without any long-term consequences.
Let’s be honest about the consequences if you put diesel into a petrol car; what you should look out for, and what you should do.
Why Diesel and Petrol Don’t Mix Well
While petrol-powered vehicles sit side by side at the pump, the working of petrol and diesel are very different. Spark plugs start the combustion of petrol engines. Diesel engines don’t. Instead, they make use of pressure.
As a result, in a petrol engine the diesel does not burn in the same way as petrol. It has a lower flash point, higher density and lower burning rate. Upon entering the system it begins to cause trouble pretty much right away.
So What Actually Happens If Diesel Goes Into a Petrol Car?
Typically, the car will tell you pretty early on.
Engine start up may be difficult. If it does start, it may run unevenly or may be weak. Other drivers experience knocks or loss of power. Others don’t go far.
If the engine continues to operate, then diesel will coat the spark plugs, fuel lines and injectors. There, repair expenses can quickly escalate.
The primary thing to take note of is timing.
If you know the error before cranking the car’s engine, you’re in a much better situation.
Signs You May Have Put Diesel in Petrol Car
The lack of immediate awareness does not apply to everyone.
Often these signals will bring on the alarm:
- The engine will not start.
- Car stalls or stumbles
- A large amount of smoke is coming out of the exhaust.
- A strong fuel smell
- Poor acceleration
If any of these occur, please pull over at the first safe opportunity.
What You Should Do Straight Away
First things first. Avoid any attempt to “drive-it-out. This tends to exacerbate matters.
If the engine is not running, do not start it. Turn off if it is running as soon as possible. From then on, the best course of action is to call a wrong fuel recovery expert in the UK, like wrongfuelrecovers.
They can clean the fuel system effectively and flushing the fuel before further damage can be caused. Modern engines are sensitive and adding up the cost of the work later is often a result of a poor guess.
Can Diesel in Petrol Ruin Your Engine?
It may but it does not necessarily.
Overtime, diesel can cause spark plug deterioration, failure of fuel injectors, and even catalytic converter failure. It is here that bills can add up rapidly.
But early intervention can be a big help. Many drivers don’t bother with major repairs because they made a timely stop.
How to Avoid Making the Same Mistake Again
It sounds like common sense, but slowing down is helpful. Often misfuelling occurs when drivers are distracted or rushed.
Always double check pump label. A few put a note inside the gas cap. Others regularly say “fuel” before pumping. This is an easy trick to remember, but effective.
FAQs
If one uses diesel fuel in a petrol car and drives the car, what will happen?
When driving, the diesel is disseminated in the system, increasing the chances of engine damage and breakdown.
What about a small amount of diesel in petrol?
Yes. Any quantity can have a negative impact on performance and must be corrected.
Does an increase in petrol solve the problem?
No. Diluting diesel is seldom the answer and it will worsen the problem.
If you have misfuelled, who should you call?
The best way is to use a professional wrong fuel recovery service.
