Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a usual mistake to make. And exactly what you have to do about it is dependent upon several different factors. If you want to find out what it is best to do to sort it out then continue reading.
Listed here are the main factors to take into account when choosing whether to get the car drained:

  1. What level of Diesel did you put in to the Mercedes, considering that the fuel capacity of your Mercedes SLK 280 is in most cases roughly 70 litres?
    1. Hardly any Diesel, as little as 3.5 litres of Diesel in a Petrol SLK 280 will more often than not not really be a massive problem. Experience has taught us that quantities under 3.5 litres (approximately 5% of the overall fuel tank) is usually able to be sufficiently diluted by totally topping the rest of the tank with Petrol.
      It is highly uncommon to come across a car going through problems because of below 5% incorrect fuel contamination. Keep in mind it's unusual - in no way impossible to encounter. There are a number of cars that don't stand any amount of fuel contamination in the slightest.
    2. Between 3.5 and 7 litres of Diesel in the Mercedes (5 to 10%) is a 50/50 scenario. Our working experience has revealed that as many motorists get away with it as all those who break down. When you are figuring out whether to chance it and just fill it up recognise that it is very much like wagering your car on black - you will have a 50/50 possibility of it being ok.
    3. Anything more than 7 litres of Diesel in your Petrol SLK 280 really should straight away be removed seeing that your likelihood of driving with that level of contamination is undoubtedly less than one in fifty - seriously long odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you noticed any performance concerns since putting the bad fuel in the SLK 280? In that case, have it drained no matter the quantity of Diesel or even the contamination ratio. Proceeding to run driving an automobile that is starting to suffer from the consequences of fuel contamination will definitely lead to more damage being caused to the fuel system components.
  3. Do you need security?
    Then get it removed. Regardless of contamination ratio, there is inevitably some degree of risk affiliated with running a Petrol engine on Petrol contaminated with the incorrect fuel. Probable final outcomes of driving a vehicle on the wrong fuel include the motor not starting, running unevenly, loss in power, degradation of the high-pressure pump, worn out or bunged injectors, and so on. These are some of the most typical Diesel in Petrol symptoms, and if you observe any of them stop driving and have it removed as soon as possible.

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.
