Vauxhall Fuel Drain


Putting Diesel in a Petrol Vauxhall is a fairly typical problem. And exactly what you need to do about it is dependent upon a variety of factors. If perhaps you would like to find out what you should do to fix it then stay with me.
Here are the most crucial variables to think about when figuring out whether or not to get it drained:

  1. What level of Diesel did you put in the Vauxhall, taking into account that the fuel capacity of the Vauxhall Insignia is probably approximately 70 litres?
    1. A small amount of Diesel, something like 3.5 litres of Diesel in a Petrol Insignia will quite often not necessarily be a massive problem. Experience has shown us that an amount under 3.5 litres (roughly 5% of the fuel tank capacity) is oftentimes able to be completely diluted by means of totally filling the remainder of the tank with the appropriate fuel.
      It is very uncommon to come across a car going through difficulties with less than 5% incorrect fuel contamination. Keep in mind that it is uncommon - in no way impossible to find. You can get certain vehicles that will not stand any amount of fuel contamination at all.
    2. Anywhere between 3.5 and 7 litres of Diesel in the Vauxhall (from 5 to 10%) is really a 50/50 scenario. Our practical experience has revealed that as many motorists get away with this as all those who break down. When you are deciding whether to chance it and just simply top it up remember that it is much like wagering all of it on black - you've got a 50/50 possibility of it working.
    3. Anything above 7 litres of Diesel in a Petrol Insignia should straight away be removed because your probability of getting away with that amount of contamination is certainly below one in 50 - really huge odds.
  2. Put Diesel in a Petrol Vauxhall and drove it: Have you observed any performance concerns since putting the bad fuel in your Insignia? If you have, get it drained no matter the volume of Diesel or the contamination percentage. Proceeding to run running an automobile that is currently beginning to suffer the effect of wrong fuel contamination can likely lead to progressively more harm being caused to your fuel system components.
  3. Are you looking for security?
    Then get it drained. Regardless of the contamination ratio, there is inevitably some degree of danger linked with running a Petrol motor on fuel contaminated with the incorrect fuel. Likely final outcomes of driving on the incorrect fuel include things like the engine not starting, running unevenly, losing power, wearing of the high-pressure pump, worn or clogged injectors, and the like. These are some of the most common Diesel in Petrol symptoms, and in the event that you notice any of them then stop driving and have 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.
