Mazda Fuel Drain


Filling up with Petrol in a Diesel Mazda is a regularly occurring problem. And what you should do about it is determined by a few things. In case you want to know what you must do about this then keep on reading.
These are the most important factors to to consider whenever making a decision whether or not to have it drained:

  1. What amount of Petrol have you put in to the Mazda, bearing in mind that the fuel tank capacity of the Mazda 323 TD is usually approximately 55 litres?
    1. A tiny amount of Petrol, less than 2.75 litres of Petrol in a Diesel 323 TD will generally not be a significant problem. Experience has proven to us that an amount under 2.75 litres (which is about 5% of the whole fuel tank) is frequently capable of being completely diluted by totally topping the rest of the tank with the appropriate fuel.
      It's extremely uncommon to find a car or truck going through difficulties because of under 5% wrong fuel contamination. Keep in mind it is very infrequent - not impossible to encounter. You will discover certain cars that won't endure any level of fuel contamination at all.
    2. In between 2.75 and 5.5 litres of Petrol in the Mazda (from 5 to 10%) is really a 50/50 condition. Our practical experience has shown us that as many people get away with it as all those who don't. When deciding whether to chance it and simply fill it up remember that it is just like gambling it all on black - you have got a 50/50 possibility of it being ok.
    3. Anything above 5.5 litres of Petrol in a Diesel 323 TD ought to immediately be drained out as your likelihood of driving with that level of contamination is probably lower than one in fifty - definitely big odds.
  2. Put Petrol in a Diesel Mazda and drove it: Have you spotted any performance issues since putting the wrong fuel in the 323 TD? If that's the case, have it removed regardless of the amount of Petrol or the contamination ratio. Continually running a vehicle that is beginning to suffer the effect of fuel contamination can only end up in more and more harm affecting the fuel system.
  3. Do you need security?
    In that case get it removed. Regardless of the contamination percentage, there is inevitably some extent of risk affiliated with driving a Diesel motor on fuel contaminated with Petrol. Likely implications of driving on the incorrect fuel include things like the motor refusing to start, running unevenly, reduced power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the most common Petrol in Diesel signs and symptoms, and in the event that you observe any of them stop and get it drained right away.

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.
