Lexus Fuel Drain


Putting Diesel in a Petrol Lexus is a fairly typical error. And exactly what you need to do about it depends on a variety of factors. In the event that you would like to know what you ought to do about this then stay with me.
Here are the most crucial factors to take into consideration when determining whether to have it drained:

  1. How much Diesel have you put in to the Lexus, taking into consideration that the fuel tank capacity of the Lexus Rx 300 is usually about 75 litres?
    1. A tiny quantity of Diesel, less than 3.75 litres of Diesel in a Petrol Rx 300 will generally not be a massive problem. Experience has demonstrated to us that quantities under 3.75 litres (which is almost 5% of the total fuel tank capacity) is frequently capable of being adequately diluted through completely topping the tank with the right fuel.
      It is highly unusual to encounter a motor vehicle experiencing issues with less than 5% wrong fuel contamination. Keep in mind it's infrequently found - certainly not impossible to find. There are actually certain cars that don't stand any degree of contamination in the slightest.
    2. Somewhere between 3.75 and 7.5 litres of Diesel in the Lexus (from 5 to 10%) is a 50/50 situation. Our working experience has revealed that as many drivers get away with this as those people who don't. Whenever you are deciding whether to risk it and just simply fill it up bear in mind that it is just like gambling all of it on black - you have got a 50/50 possibility of it working out.
    3. Anything over 7.5 litres of Diesel in your Petrol Rx 300 really should straight away be drained seeing that your probability of getting away with that quantity of contamination is probably lower than one in fifty - extremely huge odds.
  2. Put some Diesel in a Petrol Lexus and drove it: Have you noted any kind of performance issues ever since putting the bad fuel in the Rx 300? In that case, get it emptied irrespective of the quantity of Diesel or even the contamination percentage. Continuing to drive running a vehicle that is already beginning to suffer the effect of fuel contamination can definitely end up in more and more harm affecting the fuel system.
  3. Do you want reassurance?
    Simply get it drained. Regardless of the contamination percentage, there is inevitably some extent of danger affiliated with driving a Petrol vehicle on fuel contaminated with Diesel. Possible outcomes of driving on the wrong fuel include the engine not starting, running lumpy, losing power, wearing of the high-pressure pump, worn out or clogged injectors, and the like. These are several of the most typical Diesel in Petrol signs or symptoms, and in the event that you observe any of them stop and have it drained 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.
