Mazda Fuel Drain


Filling up with Petrol in a Diesel Mazda is a well-known mistake to make. And its remedy depends upon an assortment of things. In the event that you want to find out what you ought to do about it then stay with me.
Listed below are the most important variables to take into consideration when deciding whether to have a fuel drain:

  1. What amount of Petrol did you put in the Mazda, taking into account that the fuel tank capacity of the Mazda Cx-5 D is probably roughly 58 litres?
    1. A small amount of Petrol, something like 2.9 litres of Petrol in a Diesel Cx-5 D will more often than not not be a big problem. Experience has demonstrated to us that an amount less than 2.9 litres (which is 5% of the total fuel tank volume) is generally able to be completely diluted simply by entirely topping up the remainder of the tank with Diesel.
      It is pretty unusual to encounter a car or truck going through problems because of less than 5% wrong fuel contamination. Bear in mind that it is rare - certainly not impossible to find. There are a number of cars that don't stand any degree of contamination at all.
    2. Somewhere between 2.9 and 5.8 litres of Petrol in the Mazda (5 to 10%) is more of a 50/50 condition. Our working experience has revealed that as many people get away with it as all those who break down. When deciding on whether to risk it and just fill it up remember that it is much like betting your car on black - you have got a 50/50 chance of it working.
    3. Anything above 5.8 litres of Petrol in your Diesel Cx-5 D really should straight away be removed seeing as your probability of driving with that quantity of contamination is probably less than one in fifty - truly long odds.
  2. Put Petrol in a Diesel Mazda and drove it: Have you observed any performance difficulties as a result of putting the bad fuel in the Cx-5 D? If so, have it emptied regardless of the quantity of Petrol or the contamination percentage. Continually driving a car that is currently starting to suffer the consequences of fuel contamination will probably likely lead to more damage being done to your fuel system parts.
  3. Are you interested in security?
    Simply get it emptied. Regardless of contamination ratio, there is always some amount of risk affiliated with driving a Diesel engine on fuel contaminated with Petrol. Probable results of driving a vehicle on the wrong fuel include things like the engine refusing to start, running unevenly, lack of power, wearing of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the most common Petrol in Diesel warning signs, and if you recognise any of them stop and have it removed asap.

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.
