Rover Fuel Drain


Putting Diesel in a Petrol Rover is a fairly typical mistake to make. And exactly what you should do about it hinges on a variety of factors. In case you would like to find out what you must do about it then read on.
Let us discuss the most crucial factors to keep in mind when choosing whether or not to get the car drained:

  1. What level of Diesel did you put in to the Rover, considering that the fuel tank capacity of the Rover 618 i is in most cases roughly 65 litres?
    1. A small quantity of Diesel, something like 3.25 litres of Diesel in a Petrol 618 i will usually not necessarily be a significant problem. Experience has proven to us that an amount under 3.25 litres (which is roughly 5% of the entire fuel tank) is frequently capable of being adequately diluted simply by totally topping the tank with the appropriate fuel.
      It is quite rare to find an automobile suffering from difficulties with under 5% incorrect fuel contamination. Keep in mind that it's uncommon - certainly not impossible to encounter. You can get some cars that don't endure any degree of contamination in the slightest.
    2. In between 3.25 and 6.5 litres of Diesel in the Rover (5 to 10%) is really a 50/50 situation. Our expertise has shown that as many drivers get away with it as all those who don't. Whenever figuring out whether or not to risk it and basically top it up bear in mind that it is the same thing as wagering everything on black - you have a 50/50 possibility of it working out.
    3. Anything more than 6.5 litres of Diesel in a Petrol 618 i really should as soon as possible be drained because your likelihood of driving with this quantity of contamination is undoubtedly less than one in fifty - seriously long odds.
  2. Put some Diesel in a Petrol Rover and drove it: Have you detected any performance troubles since putting the incorrect fuel in your 618 i? If that's the case, have it drained irrespective of the volume of Diesel or the contamination ratio. Continually running a car that is now starting to suffer the effect of fuel contamination will probably only result in progressively more damage affecting your fuel system.
  3. Would you like peace of mind?
    Simply get it emptied. Whatever the contamination ratio, there is inevitably a certain level of risk connected with driving a Petrol motor on fuel contaminated with the wrong fuel. Probable consequences of driving on the incorrect fuel include the engine refusing to start, running unevenly, loss of power, wearing of the high-pressure pump, damaged or bunged injectors, and so on. These are a few of the most frequently seen Diesel in Petrol symptoms, and should you observe any of them stop driving 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.
