Toyota Fuel Drain


Filling Petrol in a Diesel Toyota is a very common mistake to make. And what you have to do about it depends on several different factors. In the event that you would like to find out what you have to do about it then please read on.
Let us discuss the main factors to be aware of when deciding on whether or not to have your car drained:

  1. What amount of Petrol have you put in the Toyota, considering that the fuel capacity of your Toyota Hilux is most likely approximately 80 litres?
    1. A tiny quantity of Petrol, less than 4 litres of Petrol in a Diesel Hilux will in most situations not really be a big problem. Experience has proven to us that an amount under 4 litres (almost 5% of the whole fuel tank volume) is in many instances able to be adequately diluted by means of wholly filling up the remainder of the tank with Diesel.
      It's highly uncommon to find an automobile suffering from problems because of under 5% wrong fuel contamination. Do not forget that it's uncommon - certainly not impossible to find. You can get some vehicles that don't endure any amount of contamination at all.
    2. Somewhere between 4 and 8 litres of Petrol in the Toyota (from 5 to 10%) is really a 50/50 situation. Our experience has shown us that as many drivers get away with it as those people who break down. Whenever deciding on whether or not to chance it and basically top it up recognise that it is very much like wagering all of it on black - you have a 50/50 chance of it working out.
    3. Anything in excess of 8 litres of Petrol in a Diesel Hilux really should straight away be removed because your probability of getting away with this level of contamination is in all likelihood below one in fifty - extremely long odds.
  2. Put Petrol in a Diesel Toyota and drove it: Have you seen any kind of performance concerns after putting the wrong fuel in your Hilux? If that's the case, have it drained irrespective of the volume of Petrol or even the contamination percentage. Continually running a car that is starting to suffer from the effect of fuel contamination will probably typically cause more and more damage being done to the fuel system parts.
  3. Do you need security?
    Then get it emptied. Whatever the contamination ratio, there is invariably some extent of threat caused by running a Diesel engine on Diesel contaminated with the incorrect fuel. Possible final outcomes of driving on the wrong fuel include things like the engine not starting, running unevenly, loss in power, degradation of the high-pressure pump, damaged or bunged injectors, and the like. These are several of the most frequently seen Petrol in Diesel signs or symptoms, and if you recognise any of them then cease driving and have it removed asap.

Petrol in Diesel Questions

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.
