Mercedes Fuel Drain


Filling Diesel in a Petrol Mercedes is a common mistake. And its solution depends on an assortment of things. Assuming you want to know what it is advisable to do about it then please read on.
Listed here are the main factors to be aware of when making a decision whether to get a fuel drain:

  1. How much Diesel did you put in to the Mercedes, taking into consideration that the fuel capacity of your Mercedes C160 is most likely roughly 62 litres?
    1. A modest quantity of Diesel, as little as 3.1 litres of Diesel in a Petrol C160 will quite often not necessarily be a significant problem. Experience has taught us that an amount less than 3.1 litres (approximately 5% of the whole fuel tank) is often capable of being completely diluted simply by wholly topping the remainder of the tank with Petrol.
      It's very uncommon to find a motor vehicle going through difficulties with below 5% wrong fuel contamination. Bear in mind that it's rare - in no way impossible to find. You will discover some motor vehicles that don't stand any degree of fuel contamination whatsoever.
    2. In between 3.1 and 6.2 litres of Diesel in the Mercedes (from 5 to 10%) is a 50/50 situation. Our experience has shown that as many motorists get away with this as those who break down. Whenever you are deciding upon whether to chance it and basically top it up bear in mind that it is exactly like wagering everything on black - you have got a 50/50 chance of it working.
    3. Anything in excess of 6.2 litres of Diesel in your Petrol C160 should really immediately be drained since your likelihood of driving with that level of contamination is probably below one in 50 - genuinely long odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any kind of performance problems as a result of putting the bad fuel in the C160? If so, have it emptied irrespective of the quantity of Diesel or the contamination ratio. Proceeding to run running a motor vehicle that is now beginning to suffer the effect of wrong fuel contamination can just result in progressively more harm being caused to the fuel system components.
  3. Would you like security?
    Then simply just get it removed. No matter the contamination percentage, there is always some amount of danger caused by driving a Petrol engine on fuel contaminated with the wrong fuel. Likely outcomes of driving on the incorrect fuel include the engine refusing to start, running lumpy, loss of power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are several of the commonest Diesel in Petrol signs or symptoms, and if you observe any of them stop and have it removed asap.

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.
