Rover Fuel Drain


Putting Diesel in a Petrol Rover is a regular mistake to make. And exactly what you should do about it varies according to several factors. Assuming you would like to find out what it is best to do about this then continue reading.
Listed below are the most important variables to take into account whenever deciding on whether to have your car drained:

  1. What amount of Diesel have you put into the Rover, bearing in mind that the fuel tank capacity of your Rover 414i is normally around 55 litres?
    1. A tiny quantity of Diesel, something like 2.75 litres of Diesel in a Petrol 414i will normally not really be a huge problem. Experience has shown us that an amount less than 2.75 litres (approximately 5% of the total fuel tank) is frequently able to be sufficiently diluted by wholly filling the tank with Petrol.
      It's quite uncommon to encounter an automobile having problems because of under 5% wrong fuel contamination. Be aware that it is rare - certainly not impossible to find. There are actually some motor vehicles that don't endure any degree of fuel contamination whatsoever.
    2. Somewhere between 2.75 and 5.5 litres of Diesel in the Rover (5 to 10%) is a 50/50 condition. Our expertise has shown us that as many motorists get away with it as those who break down. Any time you are deciding upon whether or not to risk it and just simply fill it up consider that it is the same thing as betting everything on black - you have a 50/50 possibility of it working out.
    3. Anything above 5.5 litres of Diesel in a Petrol 414i should really immediately be drained seeing as your probability of driving with this quantity of contamination is more than likely below one in 50 - definitely big odds.
  2. Put Diesel in a Petrol Rover and drove it: Have you noticed any performance issues since putting the incorrect fuel in the 414i? If so, get it removed irrespective of the quantity of Diesel or the contamination ratio. Proceeding to run running an automobile that is now starting to suffer the consequences of wrong fuel contamination will probably just be responsible for progressively more damage being caused to your fuel system parts.
  3. Are you interested in assurance?
    You should get it removed. Regardless of the contamination percentage, there is always some amount of danger associated with operating a Petrol vehicle on fuel contaminated with Diesel. Likely implications of driving a vehicle on the incorrect fuel include the engine refusing to start, running lumpy, reduced power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are several of the most frequently seen Diesel in Petrol warning signs, and should you recognise any of them then stop driving and get it removed as soon as possible.

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.
