Smart Fuel Drain

ABOUT

Putting Petrol in a Diesel Smart is a common mistake to make. And exactly what you should do about it is dependent upon a few factors. In the event that you want to find out what you need to do to sort it out then please read on.
Here are the most important factors to take into account whenever figuring out whether or not to get your car drained:

  1. Exactly how much Petrol did you put into the Smart, bearing in mind that the fuel capacity of the Smart Forfour cdi is most likely approximately 47 litres?
    1. A tiny amount of Petrol, something like 2.35 litres of Petrol in a Diesel Forfour cdi will quite often not really be a huge problem. Experience has taught us that quantities under 2.35 litres (close to 5% of the fuel tank) is oftentimes able to be adequately diluted by means of wholly filling the rest of the tank with the appropriate fuel.
      It is quite rare to find a car experiencing issues with under 5% wrong fuel contamination. Bear in mind that it's infrequent - definitely not impossible to find. There are actually some cars that won't stand any amount of contamination at all.
    2. Between 2.35 and 4.7 litres of Petrol in the Smart (5 to 10%) is a 50/50 situation. Our practical experience has shown that as many people get away with this as all those who break down. Whenever you are deciding on whether to risk it and just top it up remember that it is exactly like gambling all of it on black - you have a 50/50 chance of it working out.
    3. Anything above 4.7 litres of Petrol in a Diesel Forfour cdi must as soon as possible be drained out as your likelihood of succeeding with that level of contamination is more than likely below one in 50 - seriously huge odds.
  2. Put some Petrol in a Diesel Smart and drove it: Have you spotted any kind of performance problems as a result of putting the bad fuel in the Forfour cdi? If you have, have it removed no matter the volume of Petrol or even the contamination percentage. Continuing to drive driving a vehicle that is currently beginning to suffer from the consequences of wrong fuel contamination can just cause increasing amounts of damage being caused to the fuel system.
  3. Do you want assurance?
    Simply get it emptied. No matter the contamination percentage, there is always some degree of threat in connection with operating a Diesel engine on Diesel contaminated with Petrol. Likely implications of driving on the incorrect fuel include the engine refusing to start, running lumpy, loss in power, wearing of the high-pressure pump, worn out or blocked injectors, and so forth. These are some of the commonest Petrol in Diesel signs and symptoms, and in the event that you detect any of them cease driving and have it removed right away.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?

Answer

Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Diesel car on Petrol cause damage to it?

Answer

It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Petrol can I get away with in a Diesel car?

Answer

The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?

Answer

Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?

Answer

No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Diesel and add some 2-stroke oil?

Answer

This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
