Alfa Romeo Fuel Drain


Putting Diesel in a Petrol Alfa Romeo is a very common problem. And its remedy is determined by several things. In case you would like to know what to do about it then stay with me.
Right here are the key factors to think about when determining whether to have a fuel drain:

  1. What level of Diesel have you put in the Alfa Romeo, taking into account that the fuel tank capacity of your Alfa Romeo 166 is normally about 72 litres?
    1. A small amount of Diesel, less than 3.6 litres of Diesel in a Petrol 166 will in most cases not be a big problem. Experience has shown us that anything less than 3.6 litres (5% of the entire fuel tank capacity) is often able to be completely diluted simply by completely topping up the remainder of the tank with the appropriate fuel.
      It's very rare to find an automobile going through difficulties because of less than 5% wrong fuel contamination. Do not forget that it is very unusual - definitely not impossible to encounter. You will discover some vehicles that don't endure any degree of contamination in the slightest.
    2. In between 3.6 and 7.2 litres of Diesel in the Alfa Romeo (from 5 to 10%) is a 50/50 condition. Our experience has shown us that as many drivers get away with this as those people who don't. When figuring out whether to chance it and just simply fill it up bear in mind that it is exactly like gambling it all on black - you have a 50/50 possibility of it being ok.
    3. Anything above 7.2 litres of Diesel in your Petrol 166 really should straight away be drained out seeing as your probability of driving with that level of contamination is in all likelihood below one in 50 - genuinely big odds.
  2. Put some Diesel in a Petrol Alfa Romeo and drove it: Have you seen any kind of performance concerns since putting the bad fuel in your 166? If you have, get it removed no matter the quantity of Diesel or even the contamination percentage. Proceeding to drive running an automobile that is now beginning to suffer from the effect of wrong fuel contamination will only lead to increasing amounts of damage being caused to the fuel system parts.
  3. Would you like security?
    Then simply just get it emptied. No matter the contamination percentage, there is invariably some amount of threat associated with operating a Petrol engine on fuel contaminated with the wrong fuel. Possible implications of driving on the wrong fuel include the engine refusing to start, running unevenly, loss of power, degradation of the high-pressure pump, damaged or clogged injectors, and the like. These are several of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you notice any of them stop and have it removed right away.

Diesel in Petrol Questions

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.
