Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a common mistake. And exactly what you have to do about it is based on a few things. In the event that you want to know what you have to do to fix it then keep reading.
These are the key factors to consider whenever choosing whether to have a fuel drain:

  1. What level of Diesel have you put in the Mercedes, taking into account that the fuel tank capacity of your Mercedes A160 is probably approximately 54 litres?
    1. A modest quantity of Diesel, as little as 2.7 litres of Diesel in a Petrol A160 will in most situations not be a big problem. Experience has shown us that an amount under 2.7 litres (approximately 5% of the overall fuel tank capacity) is quite often capable of being adequately diluted by thoroughly topping the tank with Petrol.
      It's highly uncommon to encounter an automobile suffering from difficulties because of below 5% wrong fuel contamination. Be aware that it's infrequently found - definitely not impossible to encounter. There are actually a few cars that will not stand any degree of fuel contamination in the slightest.
    2. Anywhere between 2.7 and 5.4 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 condition. Our practical experience has shown us that as many people get away with this as those who don't. When deciding upon whether to chance it and basically fill it up recognise that it is exactly like betting your car on black - you have got a 50/50 chance of it working out.
    3. Anything in excess of 5.4 litres of Diesel in your Petrol A160 really should immediately be drained as your likelihood of succeeding with that level of contamination is very likely lower than one in 50 - definitely huge odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you spotted any performance troubles since putting the bad fuel in your A160? If you have, have it drained irrespective of the amount of Diesel or the contamination ratio. Continually driving a car that is now starting to suffer from the effect of wrong fuel contamination can typically bring about increasing amounts of damage affecting the fuel system.
  3. Do you need peace of mind?
    Simply get it emptied. Regardless of the contamination ratio, there is inevitably a certain level of threat caused by operating a Petrol vehicle on fuel contaminated with Diesel. Possible final outcomes of driving on the wrong fuel can include the motor refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or clogged injectors, and the like. These are several of the most typical Diesel in Petrol warning signs, and if you recognise any of them then stop driving and have it removed 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.
