Alfa Romeo Fuel Drain


Filling up with Petrol in a Diesel Alfa Romeo is a regularly occurring error. And its solution will depend on a variety of things. If you would like to find out what you must do about this then continue reading.
Here are the most important variables to consider whenever choosing whether to have a fuel drain:

  1. What amount of Petrol have you put in to the Alfa Romeo, keeping in mind that the fuel capacity of the Alfa Romeo 164 TD is probably about 70 litres?
    1. A modest amount of Petrol, something like 3.5 litres of Petrol in a Diesel 164 TD will in most cases not be a significant problem. Experience has shown us that anything under 3.5 litres (which is approximately 5% of the entire fuel tank) is sometimes capable of being sufficiently diluted by means of totally filling up the rest of the tank with the correct fuel.
      It's relatively uncommon to encounter a motor vehicle experiencing issues because of below 5% incorrect fuel contamination. Keep in mind it is very infrequent - in no way impossible to encounter. You can get some motor vehicles that won't endure any degree of contamination at all.
    2. Anywhere between 3.5 and 7 litres of Petrol in the Alfa Romeo (from 5 to 10%) is more of a 50/50 situation. Our practical experience has shown that as many motorists get away with it as those people who break down. Any time you are figuring out whether to risk it and just top it up remember that it is much like wagering everything on black - you have a 50/50 chance of it working.
    3. Anything above 7 litres of Petrol in a Diesel 164 TD ought to straight away be removed seeing as your probability of succeeding with that quantity of contamination is in all likelihood below one in 50 - really big odds.
  2. Put Petrol in a Diesel Alfa Romeo and drove it: Have you spotted any kind of performance problems after putting the wrong fuel in the 164 TD? If that's the case, get it emptied no matter the volume of Petrol or the contamination ratio. Continuing to run running a vehicle that is currently starting to suffer from the effects of fuel contamination will probably likely bring about more and more damage being done to your fuel system components.
  3. Do you want assurance?
    You should get it drained. Regardless of contamination ratio, there is inevitably a certain level of threat connected to operating a Diesel vehicle on Diesel contaminated with Petrol. Probable outcomes of driving on the wrong fuel include things like the engine not starting, running lumpy, reduced power, degradation of the high-pressure pump, worn out or bunged injectors, and so forth. These are several of the most frequently seen Petrol in Diesel signs and symptoms, and if you recognise any of them cease driving and have it removed right away.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
