Rover Fuel Drain


Putting Diesel in a Petrol Rover is a regularly occurring problem. And exactly what you should do about it is dependent upon several things. If you want to know what you ought to do to fix it then keep reading.
Listed below are the key factors to to consider whenever deciding whether or not to have it drained:

  1. Exactly how much Diesel have you put in to the Rover, keeping in mind that the fuel capacity of your Rover 825 Si is most likely roughly 66 litres?
    1. A modest amount of Diesel, less than 3.3 litres of Diesel in a Petrol 825 Si will generally not necessarily be a big problem. Experience has proven to us that quantities under 3.3 litres (roughly 5% of the total fuel tank) is very often able to be completely diluted by totally filling the remainder of the tank with Petrol.
      It is highly uncommon to encounter a motor vehicle having problems with lower than 5% wrong fuel contamination. Do not forget that it's rare - certainly not impossible to find. There are certain cars that won't endure any amount of contamination whatsoever.
    2. Between 3.3 and 6.6 litres of Diesel in the Rover (from 5 to 10%) is really a 50/50 condition. Our experience has revealed that as many drivers get away with it as those people who don't. When deciding upon whether or not to risk it and just fill it up remember that it is very much like betting everything on black - you will have a 50/50 chance of it working.
    3. Anything over 6.6 litres of Diesel in your Petrol 825 Si should immediately be drained since your likelihood of succeeding with this level of contamination is very likely lower than one in fifty - really big odds.
  2. Put some Diesel in a Petrol Rover and drove it: Have you seen any performance difficulties since putting the wrong fuel in the 825 Si? If you have, get it emptied regardless of the volume of Diesel or even the contamination percentage. Proceeding to drive driving a car that is already starting to suffer from the consequences of fuel contamination will definitely bring about even more damage being done to your fuel system.
  3. Are you interested in peace of mind?
    Then simply just get it removed. Regardless of contamination percentage, there is inevitably some extent of danger caused by operating a Petrol engine on Petrol contaminated with the wrong fuel. Likely results of driving on the incorrect fuel include the motor not starting, running unevenly, loss in power, degradation of the high-pressure pump, worn out or bunged injectors, and the like. These are a few of the commonest Diesel in Petrol symptoms, and if you observe any of them stop and have 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.
