Vauxhall Fuel Drain


Putting Petrol in a Diesel Vauxhall is a fairly typical mistake. And exactly what you want to do about it is based on several different things. Assuming you would like to find out what it is advisable to do to fix it then please read on.
Listed here the most crucial variables to take into consideration whenever making a decision whether or not to get your car drained:

  1. How much Petrol have you put in to the Vauxhall, considering that the fuel tank capacity of the Vauxhall Combo CDTI is in most cases about 60 litres?
    1. A modest amount of Petrol, something like 3 litres of Petrol in a Diesel Combo CDTI will generally not be a big problem. Experience has proven to us that quantities less than 3 litres (which is approximately 5% of the entire fuel tank capacity) is oftentimes able to be completely diluted by completely filling the remainder of the tank with Diesel.
      It's very rare to find a car suffering from difficulties because of less than 5% wrong fuel contamination. Bear in mind that it is rare - definitely not impossible to find. You will discover some automobiles that will not stand any amount of fuel contamination in the slightest.
    2. Anywhere between 3 and 6 litres of Petrol in the Vauxhall (5 to 10%) is really a 50/50 condition. Our practical experience demonstrates that as many drivers get away with it as those who don't. Whenever you are deciding whether to risk it and simply top it up remember that it is the same thing as betting all of it on black - you will have a 50/50 chance of it working out.
    3. Anything above 6 litres of Petrol in a Diesel Combo CDTI really should straightaway be drained out since your probability of driving with that level of contamination is more than likely lower than one in 50 - really long odds.
  2. Put some Petrol in a Diesel Vauxhall and drove it: Have you seen any performance difficulties ever since putting the bad fuel in the Combo CDTI? If you have, get it emptied regardless of the amount of Petrol or the contamination percentage. Still running a vehicle that is starting to suffer the consequences of fuel contamination will probably only be responsible for more damage being done to your fuel system parts.
  3. Are you looking for peace of mind?
    In that case get it removed. No matter the contamination percentage, there is inevitably some extent of risk resulting from running a Diesel vehicle on fuel contaminated with the incorrect fuel. Probable outcomes of driving a car on the incorrect fuel include the motor refusing to start, running lumpy, decrease in power, degradation of the high-pressure pump, damaged or bunged injectors, and so on. These are a few of the most frequently seen Petrol in Diesel warning signs, and if you detect any of them stop driving and get it removed asap.

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.
