Toyota Fuel Drain


Filling Petrol in a Diesel Toyota is a regular problem. And its remedy hinges on several different things. If perhaps you want to know what it is best to do about this then continue reading.
Listed below are the key factors to take into consideration when deciding whether to have a fuel drain:

  1. Exactly how much Petrol did you put in the Toyota, taking into account that the fuel capacity of the Toyota 4Runner TD is probably roughly 65 litres?
    1. A tiny amount of Petrol, as little as 3.25 litres of Petrol in a Diesel 4Runner TD will in most situations not be a significant problem. Experience has taught us that an amount less than 3.25 litres (roughly 5% of the fuel tank volume) is sometimes capable of being adequately diluted by thoroughly topping up the remainder of the tank with Diesel.
      It's highly rare to find a car experiencing difficulties due to less than 5% incorrect fuel contamination. Keep in mind that it is unusual - certainly not impossible to find. There are certain vehicles that won't stand any level of fuel contamination whatsoever.
    2. Somewhere between 3.25 and 6.5 litres of Petrol in the Toyota (from 5 to 10%) is more of a 50/50 scenario. Our practical experience has proven that as many drivers get away with it as those who break down. Any time you're figuring out whether or not to risk it and just simply top it up remember that it is the same as wagering it all on black - you have got a 50/50 chance of it working.
    3. Anything over 6.5 litres of Petrol in a Diesel 4Runner TD really should promptly be removed since your likelihood of succeeding with this level of contamination is very likely below one in 50 - extremely long odds.
  2. Put Petrol in a Diesel Toyota and drove it: Have you observed any kind of performance issues ever since putting the incorrect fuel in your 4Runner TD? If so, have it removed irrespective of the quantity of Petrol or even the contamination percentage. Proceeding to drive running a motor vehicle that is starting to suffer the consequences of wrong fuel contamination will probably likely end up in progressively more harm affecting the fuel system components.
  3. Are you looking for assurance?
    You should get it drained. No matter the contamination percentage, there is inevitably some extent of risk resulting from running a Diesel engine on fuel contaminated with the incorrect fuel. Probable implications of driving a car on the wrong fuel can include the motor refusing to start, running lumpy, lack of power, degradation of the high-pressure pump, worn or bunged injectors, and so on. These are several of the most typical Petrol in Diesel signs or symptoms, and in the event that you notice any of them then cease driving and have it drained asap.

Petrol in Diesel FAQs

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.
