Mazda Fuel Drain


Putting Diesel in a Petrol Mazda is a well-known error. And its remedy is based on several things. Assuming you want to find out what you have to do to sort it out then read on.
These are the most important factors to take into consideration when determining whether to get a fuel drain:

  1. What level of Diesel have you put into the Mazda, bearing in mind that the fuel tank capacity of the Mazda 323 is in most cases about 55 litres?
    1. A small amount of Diesel, less than 2.75 litres of Diesel in a Petrol 323 will usually not be a significant problem. Experience has shown us that anything under 2.75 litres (close to 5% of the overall fuel tank capacity) is frequently able to be completely diluted through completely topping the rest of the tank with the correct fuel.
      It's very uncommon to encounter a car or truck experiencing issues due to lower than 5% wrong fuel contamination. Do not forget that it is very uncommon - definitely not impossible to find. You can get a number of cars that won't stand any level of contamination whatsoever.
    2. Between 2.75 and 5.5 litres of Diesel in the Mazda (5 to 10%) is more of a 50/50 scenario. Our expertise has shown us that as many motorists get away with this as those people who break down. When deciding on whether to chance it and just simply fill it up bear in mind that it is much like wagering everything on black - you've got a 50/50 possibility of it being ok.
    3. Anything in excess of 5.5 litres of Diesel in your Petrol 323 must straight away be removed as your likelihood of driving with that amount of contamination is in all likelihood less than one in 50 - definitely long odds.
  2. Put some Diesel in a Petrol Mazda and drove it: Have you spotted any performance concerns ever since putting the wrong fuel in your 323? If you have, have it emptied irrespective of the quantity of Diesel or even the contamination ratio. Proceeding to drive running a vehicle that is now beginning to suffer from the consequences of fuel contamination will typically lead to increasing amounts of harm being caused to your fuel system.
  3. Would you like peace of mind?
    Simply get it emptied. Whatever the contamination ratio, there is inevitably some amount of threat connected with operating a Petrol motor on Petrol contaminated with Diesel. Possible outcomes of driving on the wrong fuel normally include the motor refusing to start, running lumpy, losing 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 signs or symptoms, and if you notice any of them stop and get 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.
