Honda Fuel Drain


Filling Diesel in a Petrol Honda is a very common mistake. And its solution will depend on an assortment of things. In the event that you would like to know what you must do to sort it out then stay with me.
Here are the main factors to consider when making a decision whether or not to have a fuel drain:

  1. What amount of Diesel did you put in to the Honda, bearing in mind that the fuel tank capacity of your Honda Civic DSi VTEC Hybrid is most likely roughly 50 litres?
    1. A tiny amount of Diesel, as little as 2.5 litres of Diesel in a Petrol Civic DSi VTEC Hybrid will in most situations not be a significant problem. Experience has shown us that quantities less than 2.5 litres (approximately 5% of the entire fuel tank) is frequently able to be adequately diluted simply by wholly topping up the rest of the tank with Petrol.
      It's relatively rare to encounter a car experiencing issues with less than 5% incorrect fuel contamination. Do not forget that it's infrequently found - certainly not impossible to encounter. There are a few vehicles that won't stand any degree of contamination in the slightest.
    2. In between 2.5 and 5 litres of Diesel in the Honda (5 to 10%) is really a 50/50 situation. Our experience has proven that as many drivers get away with it as those people who don't. When deciding whether to chance it and simply top it up consider that it is the same thing as wagering everything on black - you've got a 50/50 chance of it being ok.
    3. Anything more than 5 litres of Diesel in your Petrol Civic DSi VTEC Hybrid really should right away be drained out because your likelihood of driving with that amount of contamination is very likely below one in 50 - really long odds.
  2. Put Diesel in a Petrol Honda and drove it: Have you noted any performance issues as a result of putting the bad fuel in the Civic DSi VTEC Hybrid? If so, have it removed no matter the volume of Diesel or even the contamination ratio. Still running a vehicle that is already starting to suffer from the consequences of wrong fuel contamination will probably typically end up in more harm affecting your fuel system parts.
  3. Do you need assurance?
    In that case get it removed. Whatever the contamination percentage, there is inevitably some amount of risk in connection with operating a Petrol engine on fuel contaminated with Diesel. Probable final outcomes of driving a vehicle on the incorrect fuel include the engine not starting, running lumpy, losing power, wearing of the high-pressure pump, worn out or bunged injectors, and so forth. These are a few of the commonest Diesel in Petrol signs or symptoms, and if you notice any of them then stop and have it removed as soon as possible.

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.
