Vauxhall Fuel Drain


Putting Petrol in a Diesel Vauxhall is a usual error. And exactly what you need to do about it will depend on an assortment of factors. If you would like to know what to do to fix it then keep reading.
Here are the most important variables to keep in mind when deciding whether or not to have it drained:

  1. How much Petrol have you put in to the Vauxhall, bearing in mind that the fuel tank capacity of the Vauxhall Mokka CDTI is most likely about 54 litres?
    1. A small amount of Petrol, less than 2.7 litres of Petrol in a Diesel Mokka CDTI will usually not really be a massive problem. Experience has proven to us that quantities under 2.7 litres (close to 5% of the entire fuel tank capacity) is very often able to be completely diluted simply by wholly topping the tank with the correct fuel.
      It's extremely uncommon to encounter an automobile going through difficulties due to below 5% incorrect fuel contamination. Please remember it's infrequent - in no way impossible to encounter. You can get some automobiles that won't stand any amount of fuel contamination whatsoever.
    2. Somewhere between 2.7 and 5.4 litres of Petrol in the Vauxhall (from 5 to 10%) is more of a 50/50 situation. Our working experience has shown us that as many drivers get away with this as those people who don't. Whenever you are deciding upon whether or not to risk it and just simply top it up recognise that it is exactly like betting all of it on black - you will have a 50/50 chance of it being ok.
    3. Anything over 5.4 litres of Petrol in your Diesel Mokka CDTI really should straightaway be drained out seeing that your likelihood of driving with this quantity of contamination is more than likely lower than one in fifty - really long odds.
  2. Put Petrol in a Diesel Vauxhall and drove it: Have you detected any performance concerns as a result of putting the bad fuel in your Mokka CDTI? If so, have it removed regardless of the quantity of Petrol or even the contamination percentage. Still driving a vehicle that is beginning to suffer the effect of wrong fuel contamination will probably typically result in more harm affecting the fuel system components.
  3. Are you interested in assurance?
    Simply get it drained. Regardless of contamination percentage, there is always some degree of risk caused by running a Diesel vehicle on fuel contaminated with the wrong fuel. Likely implications of driving on the wrong fuel normally include the motor not starting, running lumpy, loss in power, wearing of the high-pressure pump, worn out or bunged injectors, and so on. These are several of the most typical Petrol in Diesel symptoms, and if you detect any of them stop and get it drained right away.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
