Alfa Romeo Fuel Drain


Filling Diesel in a Petrol Alfa Romeo is a common problem. And exactly what you need to do about it is dependent upon a few things. If you want to know what it is advisable to do about this then read on.
Let us discuss the key variables to take into account when choosing whether to get it drained:

  1. How much Diesel have you put into the Alfa Romeo, taking into consideration that the fuel capacity of the Alfa Romeo 145 is most likely approximately 55 litres?
    1. A modest amount of Diesel, less than 2.75 litres of Diesel in a Petrol 145 will in most cases not necessarily be a huge problem. Experience has taught us that anything under 2.75 litres (which is about 5% of the total fuel tank volume) is often able to be completely diluted through totally topping up the tank with Petrol.
      It's extremely unusual to encounter an automobile going through issues due to less than 5% incorrect fuel contamination. Do not forget that it is very uncommon - in no way impossible to find. You will discover a number of cars that don't stand any level of fuel contamination in the slightest.
    2. Anywhere between 2.75 and 5.5 litres of Diesel in the Alfa Romeo (from 5 to 10%) is really a 50/50 situation. Our expertise has shown that as many people get away with it as those who break down. Whenever you are deciding upon whether to risk it and just simply top it up recognise that it is much like gambling all of it on black - you will have a 50/50 chance of it working out.
    3. Anything in excess of 5.5 litres of Diesel in a Petrol 145 should as soon as possible be drained out seeing as your likelihood of driving with that level of contamination is probably less than one in 50 - genuinely huge odds.
  2. Put some Diesel in a Petrol Alfa Romeo and drove it: Have you observed any kind of performance difficulties ever since putting the wrong fuel in your 145? In that case, get it drained regardless of the quantity of Diesel or the contamination percentage. Still driving a motor vehicle that is already beginning to suffer the consequences of wrong fuel contamination can just cause increasing amounts of harm being caused to the fuel system parts.
  3. Are you looking for peace of mind?
    You should get it emptied. Whatever the contamination percentage, there is invariably some extent of risk affiliated with running a Petrol engine on Petrol contaminated with the wrong fuel. Possible outcomes of driving a vehicle on the incorrect fuel include the engine not starting, running lumpy, loss in power, wearing of the high-pressure pump, worn out or blocked injectors, and so on. These are some of the most frequently seen Diesel in Petrol warning signs, and should you detect any of them stop and have it drained asap.

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.
