Mazda Fuel Drain


Putting Diesel in a Petrol Mazda is a usual mistake to make. And exactly what you need to do about it will depend on several things. In the event that you want to know what it is best to do to sort it out then please read on.
Listed here are the most crucial variables to take into consideration whenever making a decision whether or not to have it drained:

  1. What amount of Diesel did you put in to the Mazda, considering that the fuel capacity of your Mazda Mx-5 is usually approximately 48 litres?
    1. A small amount of Diesel, less than 2.4 litres of Diesel in a Petrol Mx-5 will generally not be a significant problem. Experience has taught us that anything under 2.4 litres (5% of the overall fuel tank capacity) is generally able to be adequately diluted by totally filling up the tank with the correct fuel.
      It's pretty rare to encounter a car experiencing issues with less than 5% incorrect fuel contamination. Keep in mind it is rare - in no way impossible to find. You will discover certain motor vehicles that don't stand any quantity of contamination whatsoever.
    2. Between 2.4 and 4.8 litres of Diesel in the Mazda (from 5 to 10%) is really a 50/50 scenario. Our experience has shown that as many drivers get away with it as all those who break down. When you are deciding on whether or not to chance it and simply top it up remember that it is much like betting your car on black - you have got a 50/50 chance of it working out.
    3. Anything in excess of 4.8 litres of Diesel in your Petrol Mx-5 ought to as soon as possible be drained seeing as your probability of succeeding with that quantity of contamination is very likely lower than one in 50 - really long odds.
  2. Put some Diesel in a Petrol Mazda and drove it: Have you noticed any performance issues since putting the incorrect fuel in the Mx-5? If you have, get it removed irrespective of the quantity of Diesel or the contamination ratio. Still running an automobile that is currently beginning to suffer from the effects of wrong fuel contamination can likely cause more harm affecting the fuel system parts.
  3. Would you like reassurance?
    You should get it removed. No matter the contamination ratio, there is invariably a certain level of risk linked with driving a Petrol vehicle on fuel contaminated with Diesel. Possible results of driving a car on the incorrect fuel include the engine refusing to start, running unevenly, loss of power, wearing of the high-pressure pump, worn out or clogged injectors, and so forth. These are some of the most frequently seen Diesel in Petrol warning signs, and if you observe any of them cease driving 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.
