Toyota Fuel Drain


Putting Diesel in a Petrol Toyota is a regularly occurring problem. And exactly what you should do about it varies according to various factors. Assuming you want to know what you need to do about it then keep reading.
Here are the most important factors to to consider when making a decision whether to get a fuel drain:

  1. Exactly how much Diesel have you put in the Toyota, bearing in mind that the fuel capacity of the Toyota GT86 is most likely approximately 50 litres?
    1. Hardly any Diesel, something like 2.5 litres of Diesel in a Petrol GT86 will usually not really be a significant problem. Experience has proven to us that anything under 2.5 litres (close to 5% of the total fuel tank volume) is usually able to be completely diluted through thoroughly filling the rest of the tank with the appropriate fuel.
      It is relatively uncommon to find an automobile experiencing difficulties with lower than 5% incorrect fuel contamination. Please remember it is very rare - definitely not impossible to find. You will discover a few cars that will not stand any level of fuel contamination at all.
    2. Somewhere between 2.5 and 5 litres of Diesel in the Toyota (5 to 10%) is a 50/50 situation. Our expertise has revealed that as many drivers get away with it as those who don't. Any time you are figuring out whether or not to chance it and just simply fill it up recognise that it is very much like gambling your car on black - you've got a 50/50 possibility of it being ok.
    3. Anything above 5 litres of Diesel in a Petrol GT86 really should immediately be drained out as your likelihood of getting away with that level of contamination is undoubtedly less than one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Toyota and drove it: Have you detected any kind of performance problems since putting the incorrect fuel in the GT86? If you have, have it drained irrespective of the volume of Diesel or the contamination percentage. Proceeding to drive running a motor vehicle that is starting to suffer from the effects of wrong fuel contamination can just result in more and more harm affecting your fuel system parts.
  3. Do you want assurance?
    Then get it drained. No matter the contamination ratio, there is always some degree of risk linked with operating a Petrol engine on fuel contaminated with Diesel. Likely results of driving a car on the wrong fuel include things like the motor refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, worn out or clogged injectors, and so forth. These are some of the most frequently seen Diesel in Petrol signs and symptoms, and in the event that you recognise any of them then stop and get 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.
