Alfa Romeo Fuel Drain


Putting Diesel in a Petrol Alfa Romeo is a well-known mistake. And its remedy varies according to various factors. In case you would like to know what to do to fix it then keep reading.
Here are the most important factors to keep in mind when figuring out whether or not to have it drained:

  1. How much Diesel did you put into the Alfa Romeo, bearing in mind that the fuel capacity of the Alfa Romeo 4C is normally approximately 40 litres?
    1. A tiny amount of Diesel, less than 2 litres of Diesel in a Petrol 4C will generally not be a massive problem. Experience has taught us that an amount under 2 litres (which is roughly 5% of the whole fuel tank) is usually capable of being adequately diluted by means of entirely filling the remainder of the tank with Petrol.
      It's relatively rare to encounter a vehicle having problems with below 5% incorrect fuel contamination. Be aware that it is unusual - in no way impossible to encounter. You will discover certain automobiles that will not endure any amount of fuel contamination at all.
    2. Somewhere between 2 and 4 litres of Diesel in the Alfa Romeo (5 to 10%) is a 50/50 scenario. Our practical experience has proven that as many motorists get away with this as all those who break down. Any time you are figuring out whether to risk it and basically top it up remember that it is exactly like gambling it all on black - you have got a 50/50 chance of it being ok.
    3. Anything in excess of 4 litres of Diesel in a Petrol 4C should as soon as possible be drained seeing as your likelihood of driving with this level of contamination is very likely lower than one in fifty - genuinely big odds.
  2. Put some Diesel in a Petrol Alfa Romeo and drove it: Have you observed any performance concerns since putting the incorrect fuel in your 4C? If you have, have it emptied regardless of the quantity of Diesel or the contamination percentage. Proceeding to drive driving a motor vehicle that is beginning to suffer the consequences of fuel contamination will likely result in progressively more damage affecting the fuel system components.
  3. Are you looking for reassurance?
    Then simply just get it removed. Regardless of the contamination ratio, there is inevitably a certain level of threat linked with operating a Petrol vehicle on Petrol contaminated with the incorrect fuel. Probable results of driving a vehicle on the wrong fuel normally include the motor not starting, running unevenly, loss of power, wearing of the high-pressure pump, worn out or blocked injectors, and so forth. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and should you observe any of them stop and get it removed immediately.

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.
