Vauxhall Fuel Drain


Filling Diesel in a Petrol Vauxhall is a usual error. And exactly what you want to do about it will depend on a variety of factors. If perhaps you want to find out what to do to sort it out then please read on.
Listed here are the main variables to think about when figuring out whether or not to get a fuel drain:

  1. How much Diesel have you put in the Vauxhall, bearing in mind that the fuel capacity of your Vauxhall Omega is probably approximately 75 litres?
    1. Hardly any Diesel, something like 3.75 litres of Diesel in a Petrol Omega will most of the time not really be a significant problem. Experience has taught us that anything less than 3.75 litres (5% of the fuel tank) is usually capable of being completely diluted by means of totally topping up the remainder of the tank with the right fuel.
      It's quite unusual to find an automobile suffering from difficulties with less than 5% incorrect fuel contamination. Keep in mind it's infrequent - certainly not impossible to encounter. You can get certain automobiles that don't stand any quantity of contamination at all.
    2. Somewhere between 3.75 and 7.5 litres of Diesel in the Vauxhall (5 to 10%) is a 50/50 scenario. Our working experience has demonstrated that as many people get away with it as all those who don't. Any time you're deciding whether or not to chance it and just fill it up remember that it is much like betting everything on black - you've got a 50/50 chance of it working.
    3. Anything more than 7.5 litres of Diesel in a Petrol Omega should really straight away be drained out seeing that your probability of getting away with this quantity of contamination is almost certainly below one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Vauxhall and drove it: Have you noticed any kind of performance difficulties ever since putting the incorrect fuel in the Omega? If so, have it drained no matter the amount of Diesel or the contamination ratio. Still running a car that is already starting to suffer from the consequences of fuel contamination will probably definitely cause more harm affecting the fuel system components.
  3. Are you looking for security?
    Then simply just get it drained. Regardless of the contamination ratio, there is inevitably some degree of risk connected to driving a Petrol engine on fuel contaminated with the wrong fuel. Probable final outcomes of driving on the wrong fuel include the engine refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn out or clogged injectors, and the like. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you notice any of them then cease 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.
