Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a fairly typical problem. And exactly what you have to do about it is based on a variety of things. In case you would like to find out what you should do about it then stay with me.
Listed here the key factors to be aware of whenever deciding on whether to get a fuel drain:

  1. What level of Diesel did you put into the Mercedes, taking into consideration that the fuel tank capacity of the Mercedes S430 is in most cases about 88 litres?
    1. A tiny quantity of Diesel, as little as 4.4 litres of Diesel in a Petrol S430 will quite often not be a big problem. Experience has demonstrated to us that quantities under 4.4 litres (approximately 5% of the overall fuel tank capacity) is frequently capable of being sufficiently diluted through thoroughly topping up the tank with the right fuel.
      It is quite unusual to come across a motor vehicle having issues due to under 5% wrong fuel contamination. Do not forget that it is infrequent - definitely not impossible to encounter. There are actually a number of vehicles that don't endure any quantity of fuel contamination in the slightest.
    2. In between 4.4 and 8.8 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 situation. Our practical experience has demonstrated that as many motorists get away with it as those people who don't. Whenever you are deciding on whether or not to chance it and just fill it up bear in mind that it is just like betting all of it on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 8.8 litres of Diesel in a Petrol S430 really should promptly be drained out seeing that your probability of getting away with that amount of contamination is more than likely lower than one in fifty - really big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you detected any kind of performance issues ever since putting the bad fuel in your S430? In that case, get it drained no matter the amount of Diesel or even the contamination percentage. Continuing to drive driving a vehicle that is already starting to suffer the effects of fuel contamination can typically be responsible for more harm being caused to your fuel system parts.
  3. Do you want assurance?
    Then simply just get it drained. Regardless of the contamination ratio, there is inevitably some degree of danger associated with operating a Petrol vehicle on fuel contaminated with the incorrect fuel. Likely final outcomes of driving on the incorrect fuel include things like the motor refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, worn out or bunged injectors, and so on. These are a few of the most typical Diesel in Petrol symptoms, and in the event that you notice any of them then stop and have it removed right away.

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.
