Vauxhall Fuel Drain


Filling Petrol in a Diesel Vauxhall is a common mistake. And what you want to do about it is based on several different things. Assuming you want to know what to do about it then keep reading.
These are the main factors to take into account when determining whether to get the car drained:

  1. What amount of Petrol did you put in the Vauxhall, taking into consideration that the fuel capacity of your Vauxhall Vivaro CDTI is in most cases around 90 litres?
    1. A modest amount of Petrol, something like 4.5 litres of Petrol in a Diesel Vivaro CDTI will generally not be a major problem. Experience has demonstrated to us that anything under 4.5 litres (which is almost 5% of the overall fuel tank volume) is usually capable of being sufficiently diluted by means of wholly filling the tank with Diesel.
      It is rather rare to come across a car or truck experiencing issues because of under 5% incorrect fuel contamination. Keep in mind it is very unusual - certainly not impossible to find. You will discover a number of automobiles that will not stand any amount of contamination whatsoever.
    2. Anywhere between 4.5 and 9 litres of Petrol in the Vauxhall (5 to 10%) is a 50/50 scenario. Our practical experience has demonstrated that as many motorists get away with it as all those who don't. Whenever deciding on whether or not to chance it and just top it up recognise that it is very much like betting all of it on black - you will have a 50/50 possibility of it being ok.
    3. Anything over 9 litres of Petrol in a Diesel Vivaro CDTI should as soon as possible be drained out since your probability of driving with that quantity of contamination is in all likelihood below one in fifty - definitely long odds.
  2. Put Petrol in a Diesel Vauxhall and drove it: Have you seen any performance difficulties after putting the wrong fuel in your Vivaro CDTI? If that's the case, have it drained regardless of the volume of Petrol or even the contamination ratio. Proceeding to drive driving a motor vehicle that is currently starting to suffer the effects of wrong fuel contamination can just bring about more and more harm affecting the fuel system components.
  3. Would you like assurance?
    Simply get it drained. No matter the contamination ratio, there is inevitably some extent of threat in connection with operating a Diesel engine on fuel contaminated with Petrol. Possible results of driving a car on the incorrect fuel include things like the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, damaged or clogged injectors, and so on. These are some of the most typical Petrol in Diesel signs or symptoms, and should you notice any of them then stop driving and get it removed right now.

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.
