Toyota Fuel Drain


Filling up with Diesel in a Petrol Toyota is a fairly typical mistake. And what you have to do about it is dependent upon several factors. If you would like to find out what it is advisable to do about this then stay with me.
Let us discuss the key factors to take into consideration whenever determining whether or not to get a fuel drain:

  1. Exactly how much Diesel have you put into the Toyota, keeping in mind that the fuel capacity of the Toyota 4Runner is normally about 65 litres?
    1. A modest quantity of Diesel, less than 3.25 litres of Diesel in a Petrol 4Runner will in most cases not necessarily be a significant problem. Experience has demonstrated to us that quantities under 3.25 litres (which is 5% of the whole fuel tank capacity) is generally able to be adequately diluted by means of entirely filling up the rest of the tank with Petrol.
      It is extremely unusual to come across a vehicle suffering from difficulties because of below 5% wrong fuel contamination. Please remember it's uncommon - not impossible to encounter. There are actually a few motor vehicles that won't stand any amount of contamination in the slightest.
    2. Somewhere between 3.25 and 6.5 litres of Diesel in the Toyota (5 to 10%) is really a 50/50 situation. Our expertise has shown that as many drivers get away with this as all those who don't. Any time you are deciding upon whether or not to chance it and just fill it up remember that it is just like wagering everything on black - you have got a 50/50 possibility of it working.
    3. Anything in excess of 6.5 litres of Diesel in your Petrol 4Runner ought to right away be drained out as your likelihood of driving with this quantity of contamination is very likely less than one in fifty - extremely huge odds.
  2. Put some Diesel in a Petrol Toyota and drove it: Have you spotted any performance issues ever since putting the incorrect fuel in the 4Runner? If you have, have it emptied no matter the quantity of Diesel or even the contamination ratio. Continually driving a car that is already beginning to suffer the effects of fuel contamination will probably likely result in increasing amounts of harm being caused to your fuel system.
  3. Do you need security?
    Then simply just get it removed. Whatever the contamination percentage, there is invariably some amount of risk affiliated with running a Petrol engine on fuel contaminated with Diesel. Likely implications of driving on the wrong fuel include the engine refusing to start, running lumpy, reduced power, degradation of the high-pressure pump, damaged or clogged injectors, and so forth. These are several of the commonest Diesel in Petrol warning signs, and should you observe any of them stop and have it removed asap.

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.
