Daihatsu Fuel Drain


Filling Diesel in a Petrol Daihatsu is a usual mistake to make. And exactly what you have to do about it hinges on a variety of factors. In the event that you would like to know what you have to do about it then please read on.
Listed below are the main variables to be aware of whenever deciding on whether or not to get your car drained:

  1. How much Diesel have you put in to the Daihatsu, considering that the fuel tank capacity of the Daihatsu Materia is most likely approximately 40 litres?
    1. Hardly any Diesel, as little as 2 litres of Diesel in a Petrol Materia will typically not really be a huge problem. Experience has taught us that quantities under 2 litres (roughly 5% of the entire fuel tank) is quite often able to be completely diluted by totally filling up the rest of the tank with Petrol.
      It's extremely rare to encounter a motor vehicle suffering from problems with under 5% incorrect fuel contamination. Do not forget that it's uncommon - certainly not impossible to encounter. There are a number of cars that don't stand any level of contamination in the slightest.
    2. Between 2 and 4 litres of Diesel in the Daihatsu (5 to 10%) is more of a 50/50 scenario. Our practical experience has shown us that as many people get away with it as all those who break down. Any time you're deciding upon whether or not to chance it and just top it up consider that it is much like gambling everything on black - you've got a 50/50 chance of it working out.
    3. Anything more than 4 litres of Diesel in your Petrol Materia should right away be drained because your likelihood of driving with that amount of contamination is almost certainly less than one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Daihatsu and drove it: Have you noticed any kind of performance concerns since putting the incorrect fuel in the Materia? If that's the case, get it emptied irrespective of the volume of Diesel or the contamination ratio. Proceeding to run driving a car that is already starting to suffer from the consequences of fuel contamination will probably only result in more damage being done to the fuel system parts.
  3. Are you interested in assurance?
    In that case get it emptied. Regardless of the contamination ratio, there is inevitably some degree of danger affiliated with operating a Petrol motor on fuel contaminated with Diesel. Likely consequences of driving on the incorrect fuel include things like the motor not starting, running unevenly, decrease in power, degradation of the high-pressure pump, worn or bunged injectors, and so on. These are a few of the most typical Diesel in Petrol signs and symptoms, and if you recognise any of them stop and have it drained immediately.

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.
