Vauxhall Fuel Drain


Putting Diesel in a Petrol Vauxhall is a well-known problem. And its remedy is based on a few factors. In case you want to know what you must do to fix it then please read on.
Let us discuss the most crucial variables to think about whenever determining whether to have a fuel drain:

  1. What level of Diesel did you put into the Vauxhall, keeping in mind that the fuel capacity of the Vauxhall Monterey is normally around 85 litres?
    1. A tiny amount of Diesel, less than 4.25 litres of Diesel in a Petrol Monterey will quite often not be a massive problem. Experience has demonstrated to us that anything under 4.25 litres (which is almost 5% of the entire fuel tank) is frequently capable of being adequately diluted simply by thoroughly topping up the tank with the correct fuel.
      It's quite uncommon to come across a vehicle suffering from problems with below 5% incorrect fuel contamination. Keep in mind it is infrequent - definitely not impossible to encounter. You will discover some vehicles that will not endure any level of fuel contamination whatsoever.
    2. In between 4.25 and 8.5 litres of Diesel in the Vauxhall (5 to 10%) is more of a 50/50 scenario. Our experience has shown that as many people get away with this as those people who break down. When you are deciding upon whether or not to risk it and just top it up consider that it is very much like betting all of it on black - you have a 50/50 chance of it working.
    3. Anything in excess of 8.5 litres of Diesel in your Petrol Monterey really should straightaway be removed seeing as your probability of driving with this quantity of contamination is in all likelihood less than one in fifty - genuinely long odds.
  2. Put some Diesel in a Petrol Vauxhall and drove it: Have you seen any performance concerns since putting the wrong fuel in your Monterey? In that case, get it drained regardless of the volume of Diesel or the contamination percentage. Proceeding to run running a vehicle that is beginning to suffer from the effects of fuel contamination will likely be responsible for even more damage affecting your fuel system components.
  3. Are you looking for assurance?
    In that case get it drained. No matter the contamination percentage, there is always some degree of threat connected to running a Petrol engine on fuel contaminated with the wrong fuel. Likely outcomes of driving a car on the wrong fuel include the motor refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are some of the most common Diesel in Petrol signs or symptoms, and in the event that you notice any of them then cease driving and have 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.
