Smart Fuel Drain


Filling up with Petrol in a Diesel Smart is a well-known error. And its remedy depends on a variety of things. If you would like to find out what it is best to do to fix it then stay with me.
These are the most crucial factors to think about whenever deciding on whether to get it drained:

  1. What amount of Petrol have you put in the Smart, considering that the fuel tank capacity of your Smart cdi pure is usually approximately 22 litres?
    1. A tiny amount of Petrol, as little as 1.1 litres of Petrol in a Diesel cdi pure will generally not be a major problem. Experience has demonstrated to us that quantities less than 1.1 litres (close to 5% of the total fuel tank volume) is usually able to be completely diluted through thoroughly filling the tank with the appropriate fuel.
      It is highly unusual to find a car or truck having issues with lower than 5% wrong fuel contamination. Do not forget that it is unusual - certainly not impossible to encounter. You will discover a number of motor vehicles that will not stand any degree of contamination in the slightest.
    2. Between 1.1 and 2.2 litres of Petrol in the Smart (5 to 10%) is more of a 50/50 condition. Our working experience has shown us that as many motorists get away with it as those who don't. Whenever you are figuring out whether to chance it and just fill it up consider that it is the same as betting everything on black - you have got a 50/50 possibility of it being ok.
    3. Anything above 2.2 litres of Petrol in your Diesel cdi pure should really right away be drained since your probability of driving with that level of contamination is more than likely less than one in 50 - really long odds.
  2. Put Petrol in a Diesel Smart and drove it: Have you noted any performance difficulties since putting the bad fuel in your cdi pure? If you have, get it removed irrespective of the amount of Petrol or the contamination percentage. Continually driving an automobile that is currently starting to suffer from the consequences of fuel contamination will probably just end up in increasing amounts of damage affecting your fuel system components.
  3. Are you interested in peace of mind?
    Then simply just get it removed. Regardless of contamination ratio, there is invariably some degree of danger in connection with operating a Diesel engine on fuel contaminated with Petrol. Likely final outcomes of driving on the wrong fuel include things like the engine not starting, running lumpy, losing power, wearing of the high-pressure pump, worn out or blocked injectors, and the like. These are several of the most frequently seen Petrol in Diesel signs or symptoms, and should you notice any of them cease driving and have it drained right now.

Petrol in Diesel FAQs

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?


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?


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?


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?


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?


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?


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.
