Mazda Fuel Drain


Filling Diesel in a Petrol Mazda is a fairly typical mistake to make. And exactly what you need to do about it is determined by a few things. If you would like to know what to do about it then read on.
Here are the most important variables to to consider when determining whether to get a fuel drain:

  1. What amount of Diesel have you put in to the Mazda, bearing in mind that the fuel tank capacity of your Mazda 131 Lx Diesel is usually approximately 42 litres?
    1. A tiny quantity of Diesel, as little as 2.1 litres of Diesel in a Petrol 131 Lx Diesel will quite often not really be a huge problem. Experience has demonstrated to us that an amount under 2.1 litres (roughly 5% of the fuel tank volume) is often able to be adequately diluted through completely filling the tank with the right fuel.
      It is relatively unusual to find an automobile experiencing issues with less than 5% wrong fuel contamination. Keep in mind it is uncommon - not impossible to encounter. You will discover a number of automobiles that won't endure any quantity of fuel contamination in the slightest.
    2. Somewhere between 2.1 and 4.2 litres of Diesel in the Mazda (5 to 10%) is more of a 50/50 scenario. Our experience has shown us that as many motorists get away with this as all those who break down. Any time you're trying to decide whether to risk it and simply top it up consider that it is much like gambling it all on black - you have a 50/50 chance of it working out.
    3. Anything more than 4.2 litres of Diesel in your Petrol 131 Lx Diesel should promptly be drained because your likelihood of driving with this amount of contamination is very likely below one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Mazda and drove it: Have you noticed any kind of performance issues since putting the wrong fuel in the 131 Lx Diesel? If you have, have it emptied regardless of the volume of Diesel or even the contamination percentage. Proceeding to run driving a car that is now beginning to suffer the effect of fuel contamination can likely result in progressively more harm being caused to your fuel system parts.
  3. Do you want assurance?
    Then simply just get it removed. Regardless of contamination ratio, there is inevitably some degree of danger in connection with running a Petrol motor on Petrol contaminated with Diesel. Likely implications of driving on the wrong fuel include things like the motor refusing to start, running unevenly, losing power, wearing of the high-pressure pump, damaged or blocked injectors, etc. These are some of the most frequently seen Diesel in Petrol warning signs, and should you detect any of them stop and get it drained as soon as possible.

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.
