Honda Fuel Drain


Filling up with Petrol in a Diesel Honda is a very common mistake. And its remedy is dependent upon several things. If you would like to find out what it is best to do about it then continue reading.
Listed below are the most important factors to take into account when figuring out whether to have a fuel drain:

  1. What level of Petrol have you put in to the Honda, taking into consideration that the fuel tank capacity of the Honda Accord TDi is in most cases about 65 litres?
    1. A modest amount of Petrol, as little as 3.25 litres of Petrol in a Diesel Accord TDi will quite often not necessarily be a major problem. Experience has proven to us that an amount less than 3.25 litres (which is approximately 5% of the whole fuel tank) is generally able to be adequately diluted simply by entirely filling up the remainder of the tank with Diesel.
      It's very rare to find a vehicle having problems due to below 5% wrong fuel contamination. Bear in mind that it is rare - not impossible to encounter. You will discover a few cars that won't endure any quantity of contamination at all.
    2. Anywhere between 3.25 and 6.5 litres of Petrol in the Honda (from 5 to 10%) is more of a 50/50 condition. Our working experience has confirmed that as many drivers get away with this as all those who don't. When deciding whether or not to risk it and just top it up consider that it is just like wagering your car on black - you have a 50/50 chance of it being ok.
    3. Anything in excess of 6.5 litres of Petrol in a Diesel Accord TDi should immediately be removed as your likelihood of succeeding with this quantity of contamination is almost certainly less than one in 50 - truly long odds.
  2. Put Petrol in a Diesel Honda and drove it: Have you detected any kind of performance troubles after putting the incorrect fuel in your Accord TDi? If that's the case, get it drained no matter the quantity of Petrol or even the contamination ratio. Still running a motor vehicle that is currently beginning to suffer from the consequences of fuel contamination can typically bring about more damage being done to the fuel system components.
  3. Are you interested in peace of mind?
    In that case get it emptied. Regardless of contamination ratio, there is inevitably some degree of danger associated with operating a Diesel vehicle on Diesel contaminated with Petrol. Possible implications of driving on the incorrect fuel include things like the engine not starting, running lumpy, decrease in power, degradation of the high-pressure pump, worn or bunged injectors, etc. These are a few of the most common Petrol in Diesel symptoms, and if you recognise any of them then cease driving and have it removed right now.

Petrol in Diesel FAQs

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
