Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a common error. And its remedy is determined by several different things. In the event that you want to find out what it is best to do to sort it out then stay with me.
Listed here are the key factors to keep in mind when making a decision whether to have the car drained:

  1. Exactly how much Diesel did you put in the Mercedes, considering that the fuel tank capacity of your Mercedes CLA 200 is in most cases roughly 50 litres?
    1. Hardly any Diesel, less than 2.5 litres of Diesel in a Petrol CLA 200 will normally not be a big problem. Experience has taught us that an amount under 2.5 litres (which is about 5% of the entire fuel tank) is very often capable of being adequately diluted simply by entirely filling the rest of the tank with the appropriate fuel.
      It is highly unusual to find a vehicle having issues due to less than 5% wrong fuel contamination. Do not forget that it is infrequently found - definitely not impossible to encounter. There are actually some vehicles that don't endure any amount of contamination at all.
    2. Between 2.5 and 5 litres of Diesel in the Mercedes (5 to 10%) is really a 50/50 situation. Our working experience has confirmed that as many motorists get away with it as those people who break down. Any time you're trying to decide whether or not to chance it and just fill it up consider that it is the same as wagering all of it on black - you have got a 50/50 chance of it working out.
    3. Anything above 5 litres of Diesel in your Petrol CLA 200 should right away be drained out seeing as your likelihood of driving with that level of contamination is in all likelihood less than one in fifty - definitely long odds.
  2. Put Diesel in a Petrol Mercedes and drove it: Have you detected any performance problems after putting the wrong fuel in the CLA 200? If that's the case, get it removed no matter the quantity of Diesel or even the contamination percentage. Continuing to run driving a car that is already beginning to suffer the consequences of wrong fuel contamination can just lead to more and more harm affecting the fuel system parts.
  3. Do you want assurance?
    Then simply just get it drained. Regardless of the contamination percentage, there is always some amount of threat connected to running a Petrol engine on fuel contaminated with the incorrect fuel. Probable implications of driving a vehicle on the wrong fuel include the motor not starting, running lumpy, reduced power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are some of the most typical Diesel in Petrol warning signs, and should you recognise any of them then stop and get it drained right away.

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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?

Answer

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.
