Vauxhall Fuel Drain


Filling up with Petrol in a Diesel Vauxhall is a very common error. And what you need to do about it depends on various things. If perhaps you would like to know what you need to do to fix it then please read on.
Listed here are the most important variables to think about whenever making a decision whether to get your car drained:

  1. Exactly how much Petrol have you put in to the Vauxhall, keeping in mind that the fuel capacity of the Vauxhall Astra CDTI is in most cases about 52 litres?
    1. A modest quantity of Petrol, as little as 2.6 litres of Petrol in a Diesel Astra CDTI will quite often not be a significant problem. Experience has shown us that anything less than 2.6 litres (which is roughly 5% of the fuel tank capacity) is usually able to be completely diluted simply by totally filling the remainder of the tank with Diesel.
      It is highly unusual to find an automobile going through difficulties because of lower than 5% incorrect fuel contamination. Be aware that it is rare - not impossible to find. There are actually a number of automobiles that won't stand any quantity of contamination in the slightest.
    2. Anywhere between 2.6 and 5.2 litres of Petrol in the Vauxhall (5 to 10%) is really a 50/50 scenario. Our working experience has demonstrated that as many motorists get away with it as those who don't. Any time you're deciding upon whether or not to chance it and just simply top it up recognise that it is very much like betting it all on black - you have a 50/50 possibility of it working out.
    3. Anything more than 5.2 litres of Petrol in your Diesel Astra CDTI must straight away be removed seeing that your probability of succeeding with this quantity of contamination is very likely less than one in fifty - definitely long odds.
  2. Put Petrol in a Diesel Vauxhall and drove it: Have you noted any performance difficulties as a result of putting the incorrect fuel in your Astra CDTI? If so, get it removed no matter the quantity of Petrol or even the contamination percentage. Continually driving a car that is currently beginning to suffer from the effects of wrong fuel contamination can likely end up in more and more damage being caused to the fuel system components.
  3. Are you interested in security?
    Simply get it removed. Regardless of the contamination ratio, there is inevitably some amount of threat connected to operating a Diesel motor on fuel contaminated with the incorrect fuel. Probable consequences of driving a car on the wrong fuel can include the motor refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, worn out or blocked injectors, etc. These are several of the commonest Petrol in Diesel signs and symptoms, and in the event that you notice any of them then stop and get it removed immediately.

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.
