Vauxhall Fuel Drain


Putting Diesel in a Petrol Vauxhall is a regularly occurring problem. And its solution depends on a few things. In the event that you want to find out what it is best to do about it then please read on.
Listed here are the key variables to keep in mind when determining whether or not to have the car drained:

  1. Exactly how much Diesel did you put in the Vauxhall, keeping in mind that the fuel capacity of your Vauxhall Agila is usually around 45 litres?
    1. A small quantity of Diesel, something like 2.25 litres of Diesel in a Petrol Agila will quite often not necessarily be a major problem. Experience has shown us that anything under 2.25 litres (which is almost 5% of the entire fuel tank capacity) is frequently able to be adequately diluted by means of thoroughly topping the tank with the right fuel.
      It is rather uncommon to find a car or truck suffering from problems with under 5% wrong fuel contamination. Keep in mind it is very unusual - certainly not impossible to find. You can get certain vehicles that don't stand any quantity of contamination whatsoever.
    2. Anywhere between 2.25 and 4.5 litres of Diesel in the Vauxhall (5 to 10%) is a 50/50 scenario. Our experience has shown that as many motorists get away with this as those people who don't. Whenever you are deciding on whether to chance it and basically top it up consider that it is the same thing as wagering everything on black - you've got a 50/50 chance of it working out.
    3. Anything over 4.5 litres of Diesel in your Petrol Agila really should straight away be drained because your likelihood of driving with that level of contamination is very likely less than one in 50 - extremely long odds.
  2. Put Diesel in a Petrol Vauxhall and drove it: Have you spotted any kind of performance problems since putting the incorrect fuel in your Agila? If you have, get it emptied no matter the quantity of Diesel or even the contamination percentage. Proceeding to drive driving a motor vehicle that is already starting to suffer from the effects of wrong fuel contamination can only be responsible for progressively more harm being caused to your fuel system.
  3. Are you interested in peace of mind?
    Then get it drained. No matter the contamination percentage, there is inevitably some amount of danger affiliated with operating a Petrol vehicle on Petrol contaminated with Diesel. Probable consequences of driving on the incorrect fuel include things like the engine not starting, running unevenly, decrease in power, wearing of the high-pressure pump, damaged or blocked injectors, etc. These are some of the most common Diesel in Petrol signs and symptoms, and in the event that you recognise any of them stop driving and have it drained as soon as possible.

Diesel in Petrol Questions

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.
