Alfa Romeo Fuel Drain


Filling Diesel in a Petrol Alfa Romeo is a regularly occurring mistake. And its solution depends on an assortment of things. If perhaps you want to find out what you have to do about it then keep reading.
Here are the most important variables to take into account when deciding on whether or not to have a fuel drain:

  1. What level of Diesel have you put in the Alfa Romeo, keeping in mind that the fuel capacity of your Alfa Romeo 146 is normally around 51 litres?
    1. A modest quantity of Diesel, as little as 2.55 litres of Diesel in a Petrol 146 will usually not be a significant problem. Experience has demonstrated to us that an amount less than 2.55 litres (which is roughly 5% of the overall fuel tank) is oftentimes capable of being completely diluted by means of totally topping up the tank with the correct fuel.
      It is rather unusual to encounter a car or truck experiencing issues because of lower than 5% wrong fuel contamination. Please remember it is very infrequent - certainly not impossible to encounter. You can get some cars that will not stand any degree of contamination whatsoever.
    2. Between 2.55 and 5.1 litres of Diesel in the Alfa Romeo (5 to 10%) is more of a 50/50 situation. Our practical experience has demonstrated that as many motorists get away with this as those people who don't. Any time you are deciding whether to risk it and just simply fill it up consider that it is much like wagering everything on black - you've got a 50/50 chance of it working.
    3. Anything over 5.1 litres of Diesel in your Petrol 146 must straightaway be removed because your likelihood of getting away with that level of contamination is very likely lower than one in 50 - seriously big odds.
  2. Put some Diesel in a Petrol Alfa Romeo and drove it: Have you spotted any performance difficulties ever since putting the incorrect fuel in the 146? If that's the case, have it removed regardless of the amount of Diesel or even the contamination percentage. Still running a motor vehicle that is already starting to suffer from the effect of wrong fuel contamination will probably definitely cause more harm being done to your fuel system parts.
  3. Would you like peace of mind?
    In that case get it emptied. Regardless of contamination percentage, there is always some extent of danger connected to driving a Petrol vehicle on fuel contaminated with the wrong fuel. Probable consequences of driving a car on the incorrect fuel include the motor not starting, running unevenly, loss in power, wearing of the high-pressure pump, worn or blocked injectors, and the like. These are some of the most typical Diesel in Petrol warning signs, and in the event that you recognise any of them stop driving 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.
