Vauxhall Fuel Drain


Filling Diesel in a Petrol Vauxhall is a regularly occurring mistake. And exactly what you have to do about it is dependent upon a number of things. In case you would like to find out what to do to sort it out then read on.
Here are the key variables to consider when choosing whether or not to get the car drained:

  1. What amount of Diesel have you put in the Vauxhall, taking into account that the fuel tank capacity of the Vauxhall GT is usually around 49 litres?
    1. Hardly any Diesel, less than 2.45 litres of Diesel in a Petrol GT will in most situations not necessarily be a major problem. Experience has demonstrated to us that quantities less than 2.45 litres (which is almost 5% of the fuel tank capacity) is often able to be adequately diluted by means of thoroughly topping the rest of the tank with Petrol.
      It is rather unusual to encounter a vehicle going through issues because of lower than 5% wrong fuel contamination. Keep in mind it's infrequent - in no way impossible to encounter. There are a few automobiles that don't endure any degree of contamination at all.
    2. Anywhere between 2.45 and 4.9 litres of Diesel in the Vauxhall (from 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. Any time you're deciding whether or not to risk it and just simply top it up consider that it is just like wagering your car on black - you will have a 50/50 chance of it working.
    3. Anything more than 4.9 litres of Diesel in a Petrol GT ought to immediately be drained out seeing as your likelihood of driving with this quantity of contamination is in all likelihood below one in 50 - seriously huge odds.
  2. Put some Diesel in a Petrol Vauxhall and drove it: Have you seen any kind of performance concerns after putting the bad fuel in your GT? If you have, have it removed no matter the volume of Diesel or even the contamination ratio. Still driving a motor vehicle that is already starting to suffer from the consequences of fuel contamination will probably typically lead to even more damage affecting the fuel system components.
  3. Are you interested in peace of mind?
    You should get it removed. Regardless of the contamination percentage, there is always some extent of risk connected with driving a Petrol vehicle on fuel contaminated with Diesel. Likely consequences of driving a vehicle on the wrong fuel normally include the engine refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or bunged injectors, and so on. These are a few of the most typical Diesel in Petrol signs or symptoms, and should you notice any of them stop and have it drained right now.

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.
