Mazda Fuel Drain


Filling Diesel in a Petrol Mazda is a regularly occurring mistake. And exactly what you have to do about it depends upon several different things. In the event that you would like to find out what you have to do about this then keep on reading.
Here are the main variables to be aware of whenever making a decision whether or not to have the car drained:

  1. What level of Diesel have you put into the Mazda, taking into consideration that the fuel capacity of your Mazda MPV is probably around 70 litres?
    1. A small amount of Diesel, something like 3.5 litres of Diesel in a Petrol MPV will in most cases not be a massive problem. Experience has taught us that anything under 3.5 litres (roughly 5% of the entire fuel tank capacity) is sometimes able to be adequately diluted by means of wholly topping up the tank with the correct fuel.
      It's extremely unusual to encounter a motor vehicle having difficulties due to below 5% wrong fuel contamination. Keep in mind it is uncommon - definitely not impossible to find. There are certain cars that won't stand any quantity of fuel contamination at all.
    2. In between 3.5 and 7 litres of Diesel in the Mazda (5 to 10%) is more of a 50/50 situation. Our expertise has demonstrated that as many drivers get away with this as those who break down. Whenever deciding whether to chance it and basically fill it up remember that it is the same as betting everything on black - you have got a 50/50 possibility of it working out.
    3. Anything in excess of 7 litres of Diesel in your Petrol MPV ought to as soon as possible be drained seeing that your probability of driving with this level of contamination is undoubtedly below one in 50 - really long odds.
  2. Put Diesel in a Petrol Mazda and drove it: Have you detected any kind of performance troubles since putting the incorrect fuel in your MPV? If that's the case, have it drained irrespective of the volume of Diesel or the contamination ratio. Proceeding to drive driving a motor vehicle that is currently starting to suffer the effect of wrong fuel contamination can typically be responsible for increasing amounts of damage affecting your fuel system components.
  3. Do you want peace of mind?
    In that case get it removed. Whatever the contamination percentage, there is always some degree of threat associated with operating a Petrol motor on Petrol contaminated with Diesel. Likely results of driving a vehicle on the incorrect fuel can include the motor not starting, running unevenly, loss in power, degradation of the high-pressure pump, worn out or bunged injectors, and so on. These are a few of the commonest Diesel in Petrol signs or symptoms, and if you recognise any of them then stop and get it removed right now.

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.
