Daihatsu Fuel Drain


Putting Diesel in a Petrol Daihatsu is a fairly typical mistake to make. And exactly what you want to do about it depends upon a number of things. Assuming you would like to know what it is best to do about this then please read on.
Listed below are the most important factors to keep in mind whenever figuring out whether or not to get it drained:

  1. What amount of Diesel have you put into the Daihatsu, taking into consideration that the fuel tank capacity of your Daihatsu Trevis is probably approximately 36 litres?
    1. Hardly any Diesel, as little as 1.8 litres of Diesel in a Petrol Trevis will usually not necessarily be a major problem. Experience has shown us that an amount less than 1.8 litres (about 5% of the fuel tank volume) is usually capable of being sufficiently diluted simply by totally topping up the remainder of the tank with Petrol.
      It is quite rare to come across an automobile suffering from difficulties with under 5% wrong fuel contamination. Keep in mind it is infrequently found - in no way impossible to encounter. You can get some motor vehicles that won't stand any degree of fuel contamination at all.
    2. Between 1.8 and 3.6 litres of Diesel in the Daihatsu (from 5 to 10%) is really a 50/50 scenario. Our experience has revealed that as many motorists get away with this as all those who break down. Whenever you are deciding whether or not to risk it and just simply top it up bear in mind that it is exactly like wagering everything on black - you have got a 50/50 chance of it working.
    3. Anything above 3.6 litres of Diesel in your Petrol Trevis should immediately be removed seeing as your probability of driving with this amount of contamination is certainly lower than one in 50 - extremely huge odds.
  2. Put Diesel in a Petrol Daihatsu and drove it: Have you noted any performance problems ever since putting the wrong fuel in the Trevis? If so, get it drained regardless of the amount of Diesel or even the contamination percentage. Continuing to run driving a motor vehicle that is currently starting to suffer from the effects of wrong fuel contamination can only result in more and more damage affecting the fuel system parts.
  3. Do you want peace of mind?
    Then get it removed. Whatever the contamination ratio, there is always some degree of threat resulting from driving a Petrol motor on Petrol contaminated with the wrong fuel. Probable consequences of driving on the wrong fuel include things like the motor not starting, running lumpy, loss of power, degradation of the high-pressure pump, worn out or clogged injectors, and the like. These are several of the most typical Diesel in Petrol signs and symptoms, and should you observe any of them stop and have it removed asap.

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.
