Mazda Fuel Drain


Filling up with Petrol in a Diesel Mazda is a well-known mistake. And its remedy is determined by various factors. Assuming you want to find out what you have to do to sort it out then stay with me.
Listed below are the most crucial factors to think about whenever deciding whether to get a fuel drain:

  1. How much Petrol have you put into the Mazda, bearing in mind that the fuel tank capacity of your Mazda BT-50 L-Cab is probably approximately 70 litres?
    1. A small amount of Petrol, something like 3.5 litres of Petrol in a Diesel BT-50 L-Cab will in most situations not necessarily be a significant problem. Experience has proven to us that quantities under 3.5 litres (approximately 5% of the whole fuel tank volume) is oftentimes able to be sufficiently diluted by means of entirely topping the tank with Diesel.
      It is pretty uncommon to find a car suffering from difficulties due to under 5% wrong fuel contamination. Do not forget that it's infrequently found - definitely not impossible to encounter. You can get some automobiles that will not endure any level of contamination whatsoever.
    2. Between 3.5 and 7 litres of Petrol in the Mazda (5 to 10%) is really a 50/50 situation. Our experience has demonstrated that as many drivers get away with it as those people who break down. Any time you're deciding whether or not to risk it and just simply fill it up recognise that it is exactly like gambling all of it on black - you have got a 50/50 possibility of it being ok.
    3. Anything over 7 litres of Petrol in your Diesel BT-50 L-Cab should straight away be drained seeing as your probability of driving with that level of contamination is very likely lower than one in 50 - genuinely big odds.
  2. Put Petrol in a Diesel Mazda and drove it: Have you observed any performance difficulties as a result of putting the wrong fuel in the BT-50 L-Cab? In that case, get it removed no matter the volume of Petrol or even the contamination percentage. Still running an automobile that is currently beginning to suffer from the effects of wrong fuel contamination will probably definitely lead to more and more damage affecting your fuel system.
  3. Are you looking for assurance?
    In that case get it drained. Regardless of the contamination ratio, there is invariably some degree of threat resulting from driving a Diesel engine on Diesel contaminated with Petrol. Probable final outcomes of driving a vehicle on the wrong fuel can include the motor not starting, running lumpy, lack of power, degradation of the high-pressure pump, damaged or clogged injectors, and so forth. These are a few of the commonest Petrol in Diesel signs and symptoms, and in the event that you observe any of them cease driving and have it removed as soon as possible.

Petrol in Diesel FAQs

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.
