Lexus Fuel Drain


Filling up with Diesel in a Petrol Lexus is a well-known mistake to make. And exactly what you have to do about it is dependent upon a variety of factors. Assuming you would like to know what it is advisable to do to sort it out then keep on reading.
Here are the most important factors to to consider when deciding on whether to have your car drained:

  1. What amount of Diesel did you put in the Lexus, taking into account that the fuel tank capacity of the Lexus GS 460 is normally approximately 71 litres?
    1. Hardly any Diesel, as little as 3.55 litres of Diesel in a Petrol GS 460 will generally not really be a significant problem. Experience has taught us that quantities under 3.55 litres (which is roughly 5% of the overall fuel tank volume) is generally able to be sufficiently diluted by means of completely topping up the rest of the tank with the correct fuel.
      It's rather rare to come across a motor vehicle suffering from difficulties due to below 5% wrong fuel contamination. Be aware that it's uncommon - not impossible to find. There are certain vehicles that don't endure any quantity of fuel contamination whatsoever.
    2. Anywhere between 3.55 and 7.1 litres of Diesel in the Lexus (from 5 to 10%) is really a 50/50 situation. Our practical experience has confirmed that as many people get away with it as all those who don't. When deciding whether to chance it and simply top it up recognise that it is just like betting your car on black - you have got a 50/50 chance of it working out.
    3. Anything over 7.1 litres of Diesel in a Petrol GS 460 should really promptly be drained since your probability of getting away with this level of contamination is undoubtedly lower than one in fifty - extremely big odds.
  2. Put Diesel in a Petrol Lexus and drove it: Have you seen any kind of performance issues ever since putting the wrong fuel in the GS 460? If so, get it emptied no matter the quantity of Diesel or even the contamination percentage. Continually driving an automobile that is starting to suffer the consequences of fuel contamination will probably definitely bring about more harm affecting your fuel system parts.
  3. Are you interested in peace of mind?
    Then get it emptied. Regardless of the contamination ratio, there is inevitably some amount of risk in connection with running a Petrol motor on Petrol contaminated with Diesel. Possible final outcomes of driving a car on the wrong fuel include the engine not starting, running unevenly, losing power, wearing of the high-pressure pump, worn or blocked injectors, and so on. These are several of the most frequently seen Diesel in Petrol signs or symptoms, and if you notice any of them stop and have it drained immediately.

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.
