Toyota Fuel Drain


Filling up with Diesel in a Petrol Toyota is a usual error. And exactly what you should do about it is determined by a variety of factors. In the event that you want to find out what you must do about it then please read on.
Listed here the main factors to keep in mind when deciding on whether or not to get a fuel drain:

  1. What amount of Diesel have you put in the Toyota, taking into consideration that the fuel tank capacity of your Toyota Yaris is most likely approximately 45 litres?
    1. A small amount of Diesel, something like 2.25 litres of Diesel in a Petrol Yaris will in most cases not necessarily be a major problem. Experience has proven to us that an amount under 2.25 litres (which is roughly 5% of the overall fuel tank volume) is very often able to be completely diluted by completely filling the remainder of the tank with Petrol.
      It is rather unusual to encounter a car or truck going through problems with less than 5% wrong fuel contamination. Keep in mind that it is very rare - definitely not impossible to find. You will discover a few automobiles that will not stand any degree of contamination at all.
    2. Between 2.25 and 4.5 litres of Diesel in the Toyota (5 to 10%) is really a 50/50 situation. Our practical experience has shown that as many motorists get away with it as those who break down. Any time you are figuring out whether or not to risk it and basically top it up recognise that it is the same as wagering your car on black - you have got a 50/50 possibility of it working out.
    3. Anything over 4.5 litres of Diesel in a Petrol Yaris must straightaway be removed because your likelihood of getting away with this level of contamination is probably lower than one in fifty - seriously huge odds.
  2. Put some Diesel in a Petrol Toyota and drove it: Have you noticed any performance troubles after putting the wrong fuel in the Yaris? In that case, have it removed no matter the volume of Diesel or even the contamination percentage. Still driving a motor vehicle that is starting to suffer the effects of fuel contamination will typically cause even more harm being caused to your fuel system components.
  3. Are you interested in peace of mind?
    In that case get it drained. Whatever the contamination ratio, there is inevitably some extent of threat connected to running a Petrol engine on Petrol contaminated with the wrong fuel. Likely outcomes of driving on the wrong fuel normally include the engine not starting, running unevenly, reduced power, wearing of the high-pressure pump, worn out or bunged injectors, and the like. These are a few of the most typical Diesel in Petrol warning signs, and in the event that you detect any of them stop driving and have it removed immediately.

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.
