Vauxhall Fuel Drain


Filling up with Diesel in a Petrol Vauxhall is a common mistake. And its remedy is based on a few things. If perhaps you would like to find out what it is advisable to do about it then continue reading.
Listed here the main variables to take into consideration when figuring out whether or not to have it drained:

  1. How much Diesel did you put in the Vauxhall, considering that the fuel tank capacity of your Vauxhall Cascada is usually roughly 56 litres?
    1. A tiny amount of Diesel, something like 2.8 litres of Diesel in a Petrol Cascada will usually not be a big problem. Experience has proven to us that an amount under 2.8 litres (approximately 5% of the whole fuel tank capacity) is generally capable of being adequately diluted by means of completely filling the tank with Petrol.
      It's rather uncommon to come across a motor vehicle suffering from issues because of below 5% incorrect fuel contamination. Be aware that it is uncommon - not impossible to encounter. There are actually certain motor vehicles that won't stand any quantity of contamination in the slightest.
    2. Anywhere between 2.8 and 5.6 litres of Diesel in the Vauxhall (from 5 to 10%) is a 50/50 situation. Our experience has proven that as many drivers get away with this as all those who don't. Whenever you are deciding on whether or not to risk it and just simply top it up remember that it is very much like betting all of it on black - you will have a 50/50 possibility of it working out.
    3. Anything above 5.6 litres of Diesel in your Petrol Cascada should really straight away be removed because your probability of getting away with this quantity of contamination is very likely lower than one in 50 - definitely huge odds.
  2. Put some Diesel in a Petrol Vauxhall and drove it: Have you observed any performance concerns after putting the wrong fuel in the Cascada? If so, have it removed irrespective of the quantity of Diesel or the contamination percentage. Proceeding to run driving a vehicle that is beginning to suffer the effects of wrong fuel contamination will probably likely lead to more harm affecting your fuel system parts.
  3. Are you interested in assurance?
    Then get it removed. Regardless of the contamination ratio, there is invariably some extent of risk associated with running a Petrol vehicle on Petrol contaminated with Diesel. Possible implications of driving on the incorrect fuel normally include the motor refusing to start, running lumpy, decrease in power, wearing of the high-pressure pump, worn out or blocked injectors, and so forth. These are some of the commonest Diesel in Petrol warning signs, and in the event that you detect any of them then stop and get it drained right now.

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.
