Smart Fuel Drain


Putting Diesel in a Petrol Smart is a regular mistake to make. And what you want to do about it hinges on a variety of things. In the event that you want to know what you must do to fix it then stay with me.
Here are the most important factors to keep in mind when figuring out whether to get your car drained:

  1. What amount of Diesel did you put in to the Smart, keeping in mind that the fuel tank capacity of the Smart Fortwo Micro Hybrid is most likely approximately 33 litres?
    1. A modest amount of Diesel, less than 1.65 litres of Diesel in a Petrol Fortwo Micro Hybrid will normally not necessarily be a big problem. Experience has shown us that anything less than 1.65 litres (which is almost 5% of the total fuel tank capacity) is sometimes able to be completely diluted by means of thoroughly topping up the tank with Petrol.
      It's rather rare to encounter a motor vehicle having difficulties with under 5% incorrect fuel contamination. Be aware that it is very infrequently found - not impossible to encounter. You will discover a few motor vehicles that won't stand any level of fuel contamination at all.
    2. Between 1.65 and 3.3 litres of Diesel in the Smart (5 to 10%) is more of a 50/50 condition. Our working experience demonstrates that as many people get away with this as those who don't. Whenever deciding whether to risk it and just simply fill it up bear in mind that it is very much like betting everything on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 3.3 litres of Diesel in your Petrol Fortwo Micro Hybrid should really straight away be removed because your likelihood of succeeding with that quantity of contamination is more than likely below one in 50 - really long odds.
  2. Put Diesel in a Petrol Smart and drove it: Have you noted any kind of performance troubles ever since putting the wrong fuel in the Fortwo Micro Hybrid? If so, have it drained no matter the amount of Diesel or the contamination ratio. Proceeding to drive driving a car that is currently beginning to suffer from the effects of fuel contamination will probably likely lead to more and more harm affecting the fuel system parts.
  3. Do you need security?
    You should get it emptied. Regardless of contamination percentage, there is always a certain level of threat associated with running a Petrol engine on fuel contaminated with the wrong fuel. Possible final outcomes of driving on the incorrect fuel include the motor not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the commonest Diesel in Petrol signs and symptoms, and in the event that you observe any of them stop and get it drained right now.

Diesel in Petrol FAQs

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

I put Diesel in a Petrol 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 Petrol car on Diesel 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 Diesel can I get away with in a Petrol 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 Petrol 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.
