Toyota Fuel Drain


Filling Diesel in a Petrol Toyota is a regularly occurring problem. And what you should do about it will depend on a number of things. In the event that you would like to find out what it is best to do to sort it out then keep on reading.
Let us discuss the key factors to take into account when figuring out whether or not to have a fuel drain:

  1. What amount of Diesel have you put in the Toyota, keeping in mind that the fuel capacity of the Toyota Avensis is usually roughly 60 litres?
    1. Hardly any Diesel, as little as 3 litres of Diesel in a Petrol Avensis will usually not necessarily be a massive problem. Experience has proven to us that an amount under 3 litres (which is 5% of the fuel tank volume) is quite often able to be completely diluted by means of completely topping up the rest of the tank with Petrol.
      It is relatively uncommon to find a car having issues due to lower than 5% wrong fuel contamination. Please remember it is infrequently found - definitely not impossible to find. There are actually certain motor vehicles that don't endure any amount of contamination at all.
    2. Somewhere between 3 and 6 litres of Diesel in the Toyota (from 5 to 10%) is more of a 50/50 scenario. Our practical experience has shown that as many drivers get away with this as those people who don't. Whenever you are deciding on whether or not to risk it and just simply fill it up consider that it is the same thing as wagering your car on black - you have a 50/50 possibility of it working.
    3. Anything more than 6 litres of Diesel in a Petrol Avensis must straight away be drained out seeing that your likelihood of driving with this level of contamination is certainly less than one in fifty - really long odds.
  2. Put Diesel in a Petrol Toyota and drove it: Have you noticed any kind of performance problems since putting the bad fuel in your Avensis? If so, get it removed regardless of the quantity of Diesel or even the contamination ratio. Continually running a motor vehicle that is beginning to suffer the effect of fuel contamination will only lead to more harm affecting the fuel system parts.
  3. Are you looking for reassurance?
    In that case get it drained. Regardless of contamination percentage, there is always some amount of risk in connection with driving a Petrol vehicle on fuel contaminated with Diesel. Possible consequences of driving a vehicle on the wrong fuel can include the motor not starting, running unevenly, lack of power, wearing of the high-pressure pump, worn out or blocked injectors, and so forth. These are some of the most frequently seen Diesel in Petrol signs or symptoms, and in the event that you detect any of them then stop and get it removed immediately.

Diesel in Petrol Questions

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.
