Infiniti Fuel Drain


Putting Diesel in a Petrol Infiniti is a very common mistake to make. And exactly what you have to do about it will depend on an assortment of factors. If you would like to find out what it is best to do to sort it out then keep on reading.
Here are the most crucial variables to be aware of when deciding on whether to get your car drained:

  1. Exactly how much Diesel did you put in the Infiniti, considering that the fuel capacity of your Infiniti M35h is usually roughly 70 litres?
    1. A tiny amount of Diesel, less than 3.5 litres of Diesel in a Petrol M35h will in most situations not really be a huge problem. Experience has taught us that anything less than 3.5 litres (almost 5% of the total fuel tank volume) is very often capable of being sufficiently diluted by wholly topping the tank with Petrol.
      It's highly unusual to encounter a vehicle suffering from issues because of below 5% incorrect fuel contamination. Remember that it is unusual - definitely not impossible to find. There are actually certain vehicles that don't stand any amount of fuel contamination whatsoever.
    2. Anywhere between 3.5 and 7 litres of Diesel in the Infiniti (from 5 to 10%) is a 50/50 situation. Our working experience has confirmed that as many drivers get away with this as those who don't. Whenever deciding whether to risk it and basically top it up bear in mind that it is exactly like betting everything on black - you've got a 50/50 chance of it working out.
    3. Anything above 7 litres of Diesel in your Petrol M35h should straightaway be removed seeing that your likelihood of driving with that amount of contamination is undoubtedly less than one in fifty - truly huge odds.
  2. Put some Diesel in a Petrol Infiniti and drove it: Have you detected any kind of performance problems as a result of putting the bad fuel in the M35h? In that case, get it drained regardless of the quantity of Diesel or the contamination ratio. Still running a vehicle that is beginning to suffer the effect of wrong fuel contamination will probably just be responsible for progressively more damage being done to the fuel system components.
  3. Would you like security?
    Simply get it drained. No matter the contamination percentage, there is invariably a certain level of risk linked with driving a Petrol engine on fuel contaminated with Diesel. Possible final outcomes of driving a vehicle on the wrong fuel can include the motor refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are some of the most typical Diesel in Petrol signs and symptoms, and should you observe any of them then stop and get it removed right away.

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.
