Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a regularly occurring mistake to make. And what you want to do about it is determined by several different things. If perhaps you would like to find out what you should do to fix it then read on.
These are the most crucial factors to take into consideration whenever choosing whether to get a fuel drain:

  1. How much Diesel have you put in to the Mercedes, taking into account that the fuel tank capacity of your Mercedes G230 Cabrio is in most cases about 95 litres?
    1. Hardly any Diesel, as little as 4.75 litres of Diesel in a Petrol G230 Cabrio will quite often not be a significant problem. Experience has demonstrated to us that anything under 4.75 litres (which is 5% of the fuel tank) is often able to be sufficiently diluted by means of entirely topping up the remainder of the tank with the appropriate fuel.
      It's extremely unusual to encounter a car having difficulties due to lower than 5% wrong fuel contamination. Please remember it's infrequently found - in no way impossible to encounter. You can get a few automobiles that won't stand any level of contamination whatsoever.
    2. In between 4.75 and 9.5 litres of Diesel in the Mercedes (from 5 to 10%) is more of a 50/50 situation. Our expertise has shown us that as many people get away with this as all those who break down. Any time you're deciding on whether to risk it and basically top it up bear in mind that it is the same as wagering your car on black - you have got a 50/50 possibility of it working out.
    3. Anything over 9.5 litres of Diesel in your Petrol G230 Cabrio should really right away be drained out as your probability of getting away with that amount of contamination is in all likelihood lower than one in fifty - definitely huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you seen any performance concerns since putting the wrong fuel in your G230 Cabrio? In that case, have it emptied irrespective of the amount of Diesel or the contamination percentage. Continuing to run running a motor vehicle that is now starting to suffer from the effects of wrong fuel contamination will just be responsible for more harm affecting the fuel system.
  3. Are you interested in security?
    Simply get it drained. Regardless of the contamination ratio, there is inevitably a certain level of danger connected to operating a Petrol vehicle on Petrol contaminated with Diesel. Likely consequences of driving a vehicle on the wrong fuel can include the engine refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, damaged or blocked injectors, and so forth. These are a few of the most common Diesel in Petrol signs and symptoms, and should you recognise any of them then cease driving and get it drained asap.

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.
