Fiat Fuel Drain


Putting Diesel in a Petrol Fiat is a fairly typical mistake. And its remedy is dependent upon several different factors. In case you would like to find out what you ought to do about this then read on.
Listed below are the main variables to be aware of when deciding whether or not to get your car drained:

  1. Exactly how much Diesel did you put into the Fiat, taking into account that the fuel tank capacity of the Fiat Panda is in most cases roughly 37 litres?
    1. Hardly any Diesel, less than 1.85 litres of Diesel in a Petrol Panda will quite often not really be a massive problem. Experience has demonstrated to us that an amount under 1.85 litres (which is roughly 5% of the overall fuel tank capacity) is very often capable of being completely diluted by completely topping up the rest of the tank with the appropriate fuel.
      It's quite rare to find a motor vehicle going through difficulties with lower than 5% incorrect fuel contamination. Please remember it is very rare - definitely not impossible to encounter. There are some vehicles that won't stand any degree of fuel contamination in the slightest.
    2. In between 1.85 and 3.7 litres of Diesel in the Fiat (from 5 to 10%) is really a 50/50 situation. Our practical experience has shown that as many people get away with this as all those who break down. When you are figuring out whether or not to chance it and simply fill it up bear in mind that it is very much like gambling everything on black - you have got a 50/50 chance of it working out.
    3. Anything more than 3.7 litres of Diesel in a Petrol Panda ought to right away be drained seeing that your probability of driving with this quantity of contamination is probably less than one in 50 - truly huge odds.
  2. Put some Diesel in a Petrol Fiat and drove it: Have you observed any performance troubles after putting the wrong fuel in your Panda? If so, get it emptied regardless of the volume of Diesel or the contamination ratio. Still driving a motor vehicle that is starting to suffer from the effects of fuel contamination will probably only bring about more harm being caused to the fuel system parts.
  3. Do you want security?
    In that case get it emptied. Whatever the contamination percentage, there is invariably some degree of risk in connection with running a Petrol vehicle on fuel contaminated with Diesel. Possible outcomes of driving a car on the incorrect fuel include things like the engine not starting, running unevenly, decrease in power, wearing of the high-pressure pump, damaged or blocked injectors, and so forth. These are several of the most frequently seen Diesel in Petrol symptoms, and if you recognise any of them then cease driving and get it removed immediately.

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.
