Vauxhall Fuel Drain


Filling Petrol in a Diesel Vauxhall is a very common problem. And exactly what you need to do about it depends on a number of factors. If perhaps you want to find out what it is advisable to do to sort it out then keep reading.
These are the most crucial variables to consider when choosing whether to get a fuel drain:

  1. How much Petrol have you put in the Vauxhall, taking into consideration that the fuel tank capacity of your Vauxhall Zafira CDTI is in most cases roughly 58 litres?
    1. Hardly any Petrol, something like 2.9 litres of Petrol in a Diesel Zafira CDTI will normally not necessarily be a major problem. Experience has demonstrated to us that quantities less than 2.9 litres (close to 5% of the entire fuel tank capacity) is in many instances able to be adequately diluted by entirely topping the remainder of the tank with Diesel.
      It is quite uncommon to encounter a car or truck going through issues due to under 5% wrong fuel contamination. Be aware that it is infrequently found - definitely not impossible to find. You can get certain vehicles that won't endure any level of contamination in the slightest.
    2. Between 2.9 and 5.8 litres of Petrol in the Vauxhall (5 to 10%) is a 50/50 condition. Our practical experience has demonstrated that as many drivers get away with it as all those who don't. Whenever you are deciding on whether or not to chance it and simply top it up consider that it is the same thing as wagering it all on black - you will have a 50/50 possibility of it working out.
    3. Anything over 5.8 litres of Petrol in your Diesel Zafira CDTI should promptly be drained as your probability of succeeding with that amount of contamination is very likely below one in fifty - really big odds.
  2. Put some Petrol in a Diesel Vauxhall and drove it: Have you spotted any kind of performance difficulties after putting the incorrect fuel in your Zafira CDTI? In that case, have it removed no matter the quantity of Petrol or the contamination ratio. Continually driving an automobile that is starting to suffer the effect of wrong fuel contamination can likely end up in increasing amounts of damage affecting the fuel system parts.
  3. Are you interested in assurance?
    Then simply just get it drained. Whatever the contamination percentage, there is always some degree of danger linked with driving a Diesel vehicle on fuel contaminated with Petrol. Possible outcomes of driving a vehicle on the incorrect fuel include the engine not starting, running unevenly, losing power, degradation of the high-pressure pump, damaged or blocked injectors, etc. These are several of the commonest Petrol in Diesel signs or symptoms, and if you observe any of them stop driving and get it removed as soon as possible.

Petrol in Diesel Questions

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.
