Toyota Fuel Drain


Filling Diesel in a Petrol Toyota is a common problem. And its remedy varies according to several different factors. In the event that you want to know what you have to do about this then keep on reading.
These are the most important variables to take into account when deciding on whether or not to get a fuel drain:

  1. How much Diesel did you put into the Toyota, considering that the fuel tank capacity of the Toyota Previa is probably roughly 75 litres?
    1. Hardly any Diesel, as little as 3.75 litres of Diesel in a Petrol Previa will generally not be a major problem. Experience has shown us that quantities less than 3.75 litres (which is roughly 5% of the whole fuel tank) is oftentimes capable of being adequately diluted by totally topping up the rest of the tank with Petrol.
      It's quite rare to find a car or truck experiencing issues due to below 5% incorrect fuel contamination. Bear in mind that it is infrequently found - in no way impossible to find. You can get a number of automobiles that don't stand any amount of fuel contamination at all.
    2. Anywhere between 3.75 and 7.5 litres of Diesel in the Toyota (5 to 10%) is really a 50/50 scenario. Our practical experience has proven that as many people get away with this as those people who don't. Whenever deciding on whether or not to chance it and simply fill it up recognise that it is the same as wagering everything on black - you will have a 50/50 possibility of it working.
    3. Anything above 7.5 litres of Diesel in your Petrol Previa ought to straight away be drained as your likelihood of getting away with this level of contamination is in all likelihood less than one in 50 - really big odds.
  2. Put some Diesel in a Petrol Toyota and drove it: Have you noticed any kind of performance concerns as a result of putting the bad fuel in the Previa? If that's the case, get it emptied no matter the volume of Diesel or the contamination percentage. Continuing to run running a car that is currently beginning to suffer from the effect of fuel contamination will probably just be responsible for more and more harm affecting the fuel system components.
  3. Are you looking for assurance?
    In that case get it emptied. Regardless of the contamination percentage, there is inevitably a certain level of danger resulting from driving a Petrol motor on Petrol contaminated with the incorrect fuel. Likely final outcomes of driving a car on the incorrect fuel include the motor not starting, running unevenly, loss of power, degradation of the high-pressure pump, damaged or blocked injectors, and the like. These are several of the commonest Diesel in Petrol symptoms, and in the event that you notice any of them then stop driving and get it drained as soon as possible.

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.
