Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a very common mistake. And its remedy depends on an assortment of things. If perhaps you would like to find out what it is advisable to do about this then keep on reading.
Here are the most crucial factors to be aware of when deciding whether or not to have a fuel drain:

  1. What level of Petrol did you put in the Mercedes, taking into consideration that the fuel tank capacity of your Mercedes C30 CDI AMG is normally roughly 62 litres?
    1. A tiny quantity of Petrol, something like 3.1 litres of Petrol in a Diesel C30 CDI AMG will in most cases not be a significant problem. Experience has proven to us that quantities less than 3.1 litres (which is about 5% of the total fuel tank volume) is sometimes capable of being completely diluted through completely topping up the tank with the right fuel.
      It's quite uncommon to come across a vehicle experiencing difficulties with less than 5% wrong fuel contamination. Keep in mind that it is very uncommon - in no way impossible to encounter. You will discover a few automobiles that don't stand any quantity of fuel contamination in the slightest.
    2. In between 3.1 and 6.2 litres of Petrol in the Mercedes (5 to 10%) is a 50/50 scenario. Our working experience has proven that as many people get away with it as all those who break down. When you are deciding whether or not to chance it and just top it up bear in mind that it is exactly like betting everything on black - you have a 50/50 chance of it working.
    3. Anything more than 6.2 litres of Petrol in a Diesel C30 CDI AMG ought to as soon as possible be drained out seeing that your probability of driving with this amount of contamination is more than likely less than one in 50 - definitely big odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you seen any kind of performance concerns since putting the bad fuel in your C30 CDI AMG? In that case, have it drained no matter the amount of Petrol or the contamination ratio. Continuing to drive running a motor vehicle that is currently beginning to suffer the consequences of fuel contamination can typically end up in increasing amounts of harm affecting your fuel system parts.
  3. Are you interested in security?
    Simply get it emptied. Regardless of the contamination ratio, there is invariably some degree of threat resulting from operating a Diesel vehicle on fuel contaminated with the incorrect fuel. Possible outcomes of driving on the incorrect fuel can include the motor not starting, running lumpy, lack of power, degradation of the high-pressure pump, worn out or blocked injectors, and so on. These are some of the most typical Petrol in Diesel signs and symptoms, and if you notice any of them stop and have it drained immediately.

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?


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.
