Mercedes Fuel Drain


Putting Diesel in a Petrol Mercedes is a usual error. And exactly what you want to do about it depends upon several factors. In the event that you would like to find out what you should do about this then keep reading.
Listed below are the most important variables to consider whenever choosing whether to get your car drained:

  1. What level of Diesel have you put into the Mercedes, taking into consideration that the fuel capacity of the Mercedes SL 65 AMG is normally around 80 litres?
    1. A tiny amount of Diesel, as little as 4 litres of Diesel in a Petrol SL 65 AMG will in most situations not be a big problem. Experience has taught us that quantities less than 4 litres (which is about 5% of the entire fuel tank volume) is quite often able to be sufficiently diluted by thoroughly filling up the tank with the appropriate fuel.
      It is very rare to encounter an automobile suffering from issues with below 5% wrong fuel contamination. Please remember it is infrequently found - certainly not impossible to find. There are actually certain cars that don't endure any quantity of fuel contamination whatsoever.
    2. Between 4 and 8 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 scenario. Our expertise demonstrates that as many motorists get away with it as all those who break down. When deciding upon whether to risk it and simply top it up consider that it is the same as wagering all of it on black - you've got a 50/50 chance of it being ok.
    3. Anything in excess of 8 litres of Diesel in your Petrol SL 65 AMG ought to promptly be drained out since your probability of succeeding with that amount of contamination is very likely lower than one in 50 - genuinely big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you noticed any performance troubles ever since putting the wrong fuel in the SL 65 AMG? In that case, have it drained regardless of the quantity of Diesel or even the contamination percentage. Continuing to drive driving a car that is already starting to suffer the effects of fuel contamination can typically cause even more damage being done to the fuel system components.
  3. Do you need security?
    Then simply just get it removed. Whatever the contamination percentage, there is always some degree of risk in connection with operating a Petrol motor on Petrol contaminated with the wrong fuel. Likely final outcomes of driving on the incorrect fuel include things like the engine not starting, running lumpy, lack of power, degradation of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the most frequently seen Diesel in Petrol signs and symptoms, and if you notice any of them then stop driving and get it drained immediately.

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.
