Vauxhall Fuel Drain


Filling up with Petrol in a Diesel Vauxhall is a fairly typical mistake to make. And what you have to do about it varies according to a number of things. In case you want to find out what you have to do about this then continue reading.
Listed below are the most important variables to be aware of when deciding on whether or not to have the car drained:

  1. What level of Petrol have you put into the Vauxhall, keeping in mind that the fuel capacity of the Vauxhall Insignia CDTI is most likely roughly 70 litres?
    1. A modest amount of Petrol, less than 3.5 litres of Petrol in a Diesel Insignia CDTI will most of the time not necessarily be a big problem. Experience has shown us that anything under 3.5 litres (approximately 5% of the entire fuel tank) is quite often able to be adequately diluted by means of thoroughly topping the remainder of the tank with the correct fuel.
      It is rather uncommon to come across a car having issues due to lower than 5% wrong fuel contamination. Please remember it is infrequently found - not impossible to find. There are a few vehicles that will not endure any degree of contamination whatsoever.
    2. In between 3.5 and 7 litres of Petrol in the Vauxhall (5 to 10%) is really a 50/50 condition. Our practical experience demonstrates that as many drivers get away with this as those who break down. When deciding whether or not to chance it and basically fill it up remember that it is just like wagering it all on black - you will have a 50/50 possibility of it working out.
    3. Anything more than 7 litres of Petrol in a Diesel Insignia CDTI ought to straight away be drained out since your probability of driving with that quantity of contamination is almost certainly lower than one in fifty - definitely huge odds.
  2. Put some Petrol in a Diesel Vauxhall and drove it: Have you spotted any kind of performance concerns after putting the bad fuel in the Insignia CDTI? If so, have it removed regardless of the quantity of Petrol or the contamination percentage. Continually driving an automobile that is beginning to suffer from the effects of wrong fuel contamination will probably typically cause progressively more harm affecting the fuel system.
  3. Do you need assurance?
    Simply get it emptied. Regardless of the contamination percentage, there is always some extent of risk resulting from running a Diesel engine on Diesel contaminated with the incorrect fuel. Probable outcomes of driving a car on the wrong fuel include things like the motor not starting, running unevenly, loss of power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are some of the most common Petrol in Diesel signs and symptoms, and if you recognise any of them then stop and have it removed right away.

Petrol in Diesel FAQs

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.
