Mercedes Fuel Drain


Filling up with Diesel in a Petrol Mercedes is a regular error. And exactly what you should do about it is based on several different factors. Assuming you would like to find out what you need to do to fix it then stay with me.
Listed below are the most crucial factors to be aware of whenever figuring out whether to get it drained:

  1. What amount of Diesel did you put into the Mercedes, taking into account that the fuel tank capacity of your Mercedes CLS 63 AMG is usually approximately 80 litres?
    1. A tiny quantity of Diesel, less than 4 litres of Diesel in a Petrol CLS 63 AMG will usually not necessarily be a huge problem. Experience has taught us that anything less than 4 litres (which is roughly 5% of the fuel tank capacity) is generally able to be adequately diluted by means of totally topping the rest of the tank with Petrol.
      It is very uncommon to find an automobile having issues because of lower than 5% incorrect fuel contamination. Do not forget that it is very infrequent - certainly not impossible to encounter. There are actually a number of cars that will not endure any level of fuel contamination at all.
    2. Between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 scenario. Our practical experience has shown that as many motorists get away with it as those who break down. Whenever you are trying to decide whether or not to risk it and basically top it up remember that it is the same thing as gambling it all on black - you have got a 50/50 possibility of it working out.
    3. Anything above 8 litres of Diesel in a Petrol CLS 63 AMG should promptly be drained since your probability of getting away with that quantity of contamination is almost certainly below one in fifty - truly big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you spotted any kind of performance problems ever since putting the incorrect fuel in the CLS 63 AMG? If you have, have it drained regardless of the volume of Diesel or the contamination percentage. Continually driving a vehicle that is now starting to suffer from the consequences of fuel contamination will just cause progressively more damage being caused to your fuel system parts.
  3. Are you interested in security?
    In that case get it removed. Whatever the contamination ratio, there is invariably a certain level of danger linked with driving a Petrol engine on fuel contaminated with Diesel. Probable outcomes of driving on the wrong fuel include things like the motor refusing to start, running unevenly, lack of power, degradation of the high-pressure pump, worn or blocked injectors, and the like. These are a few of the most common Diesel in Petrol symptoms, and if you notice any of them stop driving and get it drained right away.

Do not simply get any general so-and-so to attend your car. We are Mercedes experts and have got the qualifications and knowledge required to make certain that you are back on the road with little hassle or worry.

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.
