Mercedes Fuel Drain


Filling Petrol in a Diesel Mercedes is a regular error. And its solution depends on several factors. In the event that you want to know what you need to do about it then keep on reading.
Listed here the most important factors to to consider when choosing whether or not to get a fuel drain:

  1. Exactly how much Petrol did you put in the Mercedes, taking into consideration that the fuel capacity of your Mercedes A180 CDI is most likely about 54 litres?
    1. Hardly any Petrol, something like 2.7 litres of Petrol in a Diesel A180 CDI will normally not really be a significant problem. Experience has proven to us that an amount less than 2.7 litres (about 5% of the fuel tank) is frequently able to be completely diluted by entirely topping up the remainder of the tank with Diesel.
      It's relatively unusual to come across a motor vehicle going through issues with below 5% incorrect fuel contamination. Be aware that it is very unusual - definitely not impossible to find. There are actually some automobiles that won't endure any level of fuel contamination at all.
    2. Somewhere between 2.7 and 5.4 litres of Petrol in the Mercedes (5 to 10%) is really a 50/50 situation. Our working experience has shown us that as many drivers get away with this as those people who don't. Whenever deciding on whether to risk it and simply top it up consider that it is much like betting your car on black - you will have a 50/50 chance of it working out.
    3. Anything in excess of 5.4 litres of Petrol in your Diesel A180 CDI ought to straightaway be drained out seeing that your probability of getting away with this quantity of contamination is very likely less than one in 50 - definitely big odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you observed any performance troubles ever since putting the wrong fuel in the A180 CDI? If so, get it drained no matter the volume of Petrol or the contamination ratio. Proceeding to run running a motor vehicle that is starting to suffer the consequences of fuel contamination will probably definitely bring about more harm being caused to your fuel system parts.
  3. Are you interested in security?
    Then get it removed. Regardless of the contamination percentage, there is always a certain level of threat caused by running a Diesel motor on Diesel contaminated with the incorrect fuel. Possible final outcomes of driving on the wrong fuel normally include the motor not starting, running lumpy, reduced power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are some of the commonest Petrol in Diesel symptoms, and in the event that you recognise any of them then stop driving and get it removed asap.

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.
