Mercedes Fuel Drain

ABOUT

Filling Petrol in a Diesel Mercedes is a regularly occurring mistake to make. And its solution depends on a number of factors. In the event that you want to find out what you have to do to sort it out then please read on.
Listed here the most crucial factors to take into account when choosing whether to get the car drained:

  1. What amount of Petrol did you put in the Mercedes, taking into consideration that the fuel tank capacity of the Mercedes G400 CDI Cabrio is in most cases approximately 96 litres?
    1. A small amount of Petrol, as little as 4.8 litres of Petrol in a Diesel G400 CDI Cabrio will quite often not necessarily be a major problem. Experience has demonstrated to us that anything less than 4.8 litres (which is almost 5% of the whole fuel tank) is quite often capable of being sufficiently diluted through entirely topping up the rest of the tank with Diesel.
      It is relatively uncommon to come across an automobile having issues because of lower than 5% wrong fuel contamination. Keep in mind it is very infrequent - in no way impossible to encounter. There are a few vehicles that won't stand any degree of contamination in the slightest.
    2. In between 4.8 and 9.6 litres of Petrol in the Mercedes (5 to 10%) is really a 50/50 scenario. Our expertise has confirmed that as many drivers get away with this as those people who break down. Whenever deciding upon whether or not to risk it and basically fill it up recognise that it is just like gambling it all on black - you've got a 50/50 possibility of it working out.
    3. Anything above 9.6 litres of Petrol in your Diesel G400 CDI Cabrio really should straight away be drained as your probability of driving with this quantity of contamination is almost certainly below one in 50 - really long odds.
  2. Put Petrol in a Diesel Mercedes and drove it: Have you spotted any kind of performance issues after putting the incorrect fuel in your G400 CDI Cabrio? If that's the case, get it drained irrespective of the quantity of Petrol or the contamination percentage. Continuing to drive driving an automobile that is beginning to suffer from the consequences of fuel contamination will probably likely cause increasing amounts of harm affecting the fuel system parts.
  3. Do you need peace of mind?
    Then get it removed. Regardless of the contamination ratio, there is inevitably some extent of risk connected to running a Diesel vehicle on fuel contaminated with the wrong fuel. Possible final outcomes of driving on the incorrect fuel include the engine not starting, running lumpy, losing power, degradation of the high-pressure pump, worn or clogged injectors, and so forth. These are several of the most typical Petrol in Diesel warning signs, and in the event that you recognise any of them then stop 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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
