Vauxhall Fuel Drain


Putting Diesel in a Petrol Vauxhall is a common error. And its solution is based on an assortment of factors. Assuming you want to find out what it is best to do about this then continue reading.
Listed here the most important factors to take into account when deciding on whether or not to get it drained:

  1. Exactly how much Diesel did you put in to the Vauxhall, taking into account that the fuel tank capacity of the Vauxhall Mokka is most likely about 53 litres?
    1. A small amount of Diesel, as little as 2.65 litres of Diesel in a Petrol Mokka will more often than not not be a big problem. Experience has proven to us that an amount less than 2.65 litres (roughly 5% of the total fuel tank volume) is frequently able to be sufficiently diluted by thoroughly filling up the rest of the tank with Petrol.
      It is quite unusual to come across a car experiencing problems due to lower than 5% wrong fuel contamination. Do not forget that it's infrequent - in no way impossible to find. There are certain cars that will not stand any amount of contamination at all.
    2. In between 2.65 and 5.3 litres of Diesel in the Vauxhall (5 to 10%) is a 50/50 condition. Our expertise has shown us that as many people get away with this as those people who break down. When deciding on whether to chance it and simply top it up bear in mind that it is just like gambling it all on black - you have a 50/50 possibility of it being ok.
    3. Anything over 5.3 litres of Diesel in a Petrol Mokka should immediately be drained out since your likelihood of getting away with that quantity of contamination is certainly less than one in 50 - really long odds.
  2. Put Diesel in a Petrol Vauxhall and drove it: Have you detected any kind of performance concerns since putting the wrong fuel in the Mokka? If so, get it emptied regardless of the amount of Diesel or even the contamination percentage. Continuing to run running an automobile that is beginning to suffer from the effects of wrong fuel contamination can only cause increasing amounts of damage being caused to your fuel system.
  3. Do you need assurance?
    In that case get it emptied. Regardless of the contamination ratio, there is invariably some amount of threat associated with driving a Petrol vehicle on fuel contaminated with the incorrect fuel. Probable implications of driving a vehicle on the incorrect fuel normally include the motor refusing to start, running unevenly, loss of power, wearing of the high-pressure pump, damaged or blocked injectors, etc. These are a few of the most common Diesel in Petrol signs and symptoms, and should you notice any of them then stop driving and get it removed right now.

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.
