Mazda Fuel Drain


Filling up with Petrol in a Diesel Mazda is a regular mistake to make. And its solution depends upon various things. Assuming you would like to know what you should do about it then stay with me.
Listed here the main factors to take into account whenever deciding on whether to have a fuel drain:

  1. How much Petrol did you put in the Mazda, considering that the fuel tank capacity of your Mazda MPV Turbodiesel is normally around 75 litres?
    1. A small amount of Petrol, something like 3.75 litres of Petrol in a Diesel MPV Turbodiesel will quite often not necessarily be a huge problem. Experience has taught us that quantities less than 3.75 litres (close to 5% of the fuel tank capacity) is very often able to be completely diluted simply by thoroughly filling the rest of the tank with the correct fuel.
      It is extremely rare to find a car or truck experiencing problems with less than 5% incorrect fuel contamination. Bear in mind that it is rare - definitely not impossible to find. You can get a number of motor vehicles that will not stand any quantity of fuel contamination at all.
    2. Anywhere between 3.75 and 7.5 litres of Petrol in the Mazda (from 5 to 10%) is a 50/50 scenario. Our practical experience demonstrates that as many people get away with this as those who don't. Whenever trying to decide whether to risk it and just simply top it up remember that it is just like gambling it all on black - you have a 50/50 chance of it working out.
    3. Anything over 7.5 litres of Petrol in a Diesel MPV Turbodiesel must right away be drained seeing as your likelihood of succeeding with that quantity of contamination is undoubtedly lower than one in fifty - genuinely long odds.
  2. Put Petrol in a Diesel Mazda and drove it: Have you noticed any performance troubles ever since putting the incorrect fuel in your MPV Turbodiesel? If so, get it removed no matter the volume of Petrol or even the contamination ratio. Still running a vehicle that is currently starting to suffer from the consequences of wrong fuel contamination can likely cause increasing amounts of harm affecting the fuel system parts.
  3. Are you looking for reassurance?
    Simply get it drained. No matter the contamination percentage, there is inevitably some extent of danger affiliated with operating a Diesel vehicle on Diesel contaminated with the incorrect fuel. Probable results of driving a car on the wrong fuel include things like the engine refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn out or clogged injectors, and so on. These are several of the most common Petrol in Diesel warning signs, and in the event that you notice any of them stop and have it drained right now.

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.
