Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a regular problem. And what you have to do about it is determined by several different factors. In the event that you would like to find out what you need to do to sort it out then keep reading.
These are the main variables to think about when making a decision whether or not to have a fuel drain:

  1. What level of Diesel have you put in to the Mercedes, keeping in mind that the fuel capacity of the Mercedes SL 60 AMG is most likely roughly 80 litres?
    1. Hardly any Diesel, something like 4 litres of Diesel in a Petrol SL 60 AMG will more often than not not really be a significant problem. Experience has taught us that anything under 4 litres (which is close to 5% of the total fuel tank volume) is in many instances able to be completely diluted simply by entirely topping up the rest of the tank with Petrol.
      It's very uncommon to come across an automobile going through issues because of under 5% incorrect fuel contamination. Keep in mind it is very unusual - definitely not impossible to encounter. There are certain automobiles that will not endure any level of contamination at all.
    2. Between 4 and 8 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 scenario. Our practical experience has shown that as many motorists get away with it as those who break down. When trying to decide whether to risk it and just fill it up recognise that it is exactly like betting everything on black - you have a 50/50 chance of it being ok.
    3. Anything over 8 litres of Diesel in your Petrol SL 60 AMG ought to straightaway be drained out because your probability of getting away with this amount of contamination is certainly lower than one in 50 - really big odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you observed any performance troubles as a result of putting the incorrect fuel in your SL 60 AMG? If that's the case, get it drained irrespective of the quantity of Diesel or even the contamination ratio. Proceeding to drive running a car that is starting to suffer from the effect of fuel contamination will likely cause increasing amounts of damage affecting the fuel system parts.
  3. Do you need assurance?
    In that case get it removed. Regardless of the contamination ratio, there is inevitably some degree of risk linked with driving a Petrol vehicle on Petrol contaminated with Diesel. Likely implications of driving on the wrong fuel include the motor not starting, running unevenly, losing power, degradation of the high-pressure pump, worn out or blocked injectors, and the like. These are some of the commonest Diesel in Petrol signs and symptoms, and should you notice any of them cease driving and have it drained immediately.

Diesel in Petrol Questions

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.
