Mazda Fuel Drain


Putting Diesel in a Petrol Mazda is a fairly typical mistake. And its remedy is dependent upon a variety of factors. If you would like to find out what to do to fix it then keep on reading.
Listed here are the most important factors to consider when making a decision whether or not to get it drained:

  1. What amount of Diesel have you put in to the Mazda, keeping in mind that the fuel capacity of the Mazda 626 is in most cases roughly 64 litres?
    1. A modest quantity of Diesel, less than 3.2 litres of Diesel in a Petrol 626 will quite often not necessarily be a huge problem. Experience has proven to us that anything less than 3.2 litres (which is 5% of the whole fuel tank) is very often able to be adequately diluted through wholly topping the rest of the tank with the correct fuel.
      It is quite uncommon to encounter a car or truck going through issues with under 5% incorrect fuel contamination. Please remember it is very infrequent - not impossible to encounter. There are actually a number of automobiles that don't endure any amount of contamination at all.
    2. In between 3.2 and 6.4 litres of Diesel in the Mazda (from 5 to 10%) is more of a 50/50 situation. Our practical experience has demonstrated that as many people get away with it as those people who break down. Any time you're deciding on whether or not to chance it and simply fill it up remember that it is the same as gambling all of it on black - you've got a 50/50 possibility of it being ok.
    3. Anything in excess of 6.4 litres of Diesel in your Petrol 626 should as soon as possible be removed because your probability of driving with this level of contamination is almost certainly less than one in 50 - truly big odds.
  2. Put some Diesel in a Petrol Mazda and drove it: Have you observed any kind of performance issues since putting the bad fuel in your 626? If that's the case, have it drained irrespective of the quantity of Diesel or even the contamination percentage. Proceeding to run driving a motor vehicle that is now beginning to suffer from the effects of wrong fuel contamination can likely be responsible for progressively more harm being done to the fuel system parts.
  3. Do you need reassurance?
    Then get it drained. No matter the contamination ratio, there is always a certain level of danger affiliated with driving a Petrol motor on fuel contaminated with Diesel. Possible outcomes of driving a vehicle on the incorrect fuel include things like the engine refusing to start, running lumpy, losing power, degradation of the high-pressure pump, worn or clogged injectors, and so on. These are a few of the commonest Diesel in Petrol warning signs, and if you recognise any of them stop and have it removed right away.

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.
