Daihatsu Fuel Drain


Filling Diesel in a Petrol Daihatsu is a usual error. And what you have to do about it varies according to several different things. Assuming you want to find out what you ought to do to sort it out then keep on reading.
Let us discuss the most important factors to think about whenever choosing whether or not to have the car drained:

  1. Exactly how much Diesel have you put into the Daihatsu, taking into account that the fuel capacity of the Daihatsu Sirion is in most cases around 40 litres?
    1. A tiny quantity of Diesel, as little as 2 litres of Diesel in a Petrol Sirion will in most cases not be a big problem. Experience has demonstrated to us that anything under 2 litres (which is almost 5% of the overall fuel tank volume) is oftentimes able to be adequately diluted by means of thoroughly topping the tank with the correct fuel.
      It's quite uncommon to encounter an automobile having problems because of lower than 5% wrong fuel contamination. Be aware that it is rare - definitely not impossible to find. You will discover certain automobiles that won't stand any degree of fuel contamination in the slightest.
    2. In between 2 and 4 litres of Diesel in the Daihatsu (5 to 10%) is really a 50/50 situation. Our practical experience demonstrates that as many people get away with it as all those who don't. Any time you're deciding upon whether or not to chance it and just top it up remember that it is exactly like betting all of it on black - you have a 50/50 chance of it being ok.
    3. Anything more than 4 litres of Diesel in your Petrol Sirion should promptly be drained out as your probability of succeeding with this level of contamination is more than likely less than one in 50 - genuinely long odds.
  2. Put Diesel in a Petrol Daihatsu and drove it: Have you observed any performance difficulties since putting the incorrect fuel in your Sirion? If that's the case, have it drained regardless of the quantity of Diesel or the contamination percentage. Continually running a car that is currently beginning to suffer from the effect of fuel contamination will likely end up in progressively more harm being done to the fuel system parts.
  3. Are you looking for assurance?
    Then simply just get it drained. Whatever the contamination percentage, there is inevitably a certain level of risk connected with driving a Petrol motor on Petrol contaminated with the incorrect fuel. Likely implications of driving on the wrong fuel include things like the motor refusing to start, running lumpy, loss of power, degradation of the high-pressure pump, worn out or blocked injectors, and so on. These are a few of the commonest Diesel in Petrol symptoms, and should you observe any of them stop and have it drained as soon as possible.

Diesel in Petrol Questions

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.
