Vauxhall Fuel Drain


Filling Diesel in a Petrol Vauxhall is a common mistake to make. And exactly what you need to do about it depends upon a number of factors. In case you would like to know what you have to do to sort it out then continue reading.
These are the most important factors to be aware of whenever determining whether to have the car drained:

  1. How much Diesel have you put into the Vauxhall, keeping in mind that the fuel capacity of the Vauxhall Tigra is usually roughly 45 litres?
    1. Hardly any Diesel, as little as 2.25 litres of Diesel in a Petrol Tigra will in most cases not really be a big problem. Experience has taught us that anything under 2.25 litres (which is approximately 5% of the overall fuel tank capacity) is very often able to be adequately diluted by thoroughly topping the rest of the tank with the correct fuel.
      It's pretty rare to find a motor vehicle having problems because of under 5% wrong fuel contamination. Do not forget that it is very rare - certainly not impossible to encounter. There are a number of automobiles that will not stand any level of contamination at all.
    2. Anywhere between 2.25 and 4.5 litres of Diesel in the Vauxhall (from 5 to 10%) is really a 50/50 condition. Our practical experience demonstrates that as many people get away with it as all those who don't. When trying to decide whether to risk it and just top it up consider that it is exactly like wagering everything on black - you will have a 50/50 possibility of it working out.
    3. Anything in excess of 4.5 litres of Diesel in a Petrol Tigra ought to promptly be removed because your likelihood of driving with this amount of contamination is more than likely lower than one in 50 - definitely huge odds.
  2. Put some Diesel in a Petrol Vauxhall and drove it: Have you detected any kind of performance problems as a result of putting the wrong fuel in your Tigra? If you have, have it removed no matter the volume of Diesel or even the contamination ratio. Continually running a car that is now beginning to suffer from the effect of fuel contamination will definitely result in increasing amounts of damage being caused to the fuel system components.
  3. Are you looking for assurance?
    Then simply just get it drained. Regardless of the contamination percentage, there is invariably some extent of threat associated with running a Petrol motor on fuel contaminated with the wrong fuel. Probable final outcomes of driving a vehicle on the wrong fuel can include the engine not starting, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or clogged injectors, and so forth. These are some of the commonest Diesel in Petrol symptoms, and should you recognise any of them stop and get it drained right away.

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.
