Lexus Fuel Drain


Filling Diesel in a Petrol Lexus is a fairly typical mistake to make. And what you have to do about it depends on a few things. If you would like to find out what to do to sort it out then please read on.
Here are the key factors to take into consideration whenever figuring out whether to get your car drained:

  1. What amount of Diesel did you put in the Lexus, keeping in mind that the fuel tank capacity of your Lexus GS 450h is probably about 65 litres?
    1. A tiny quantity of Diesel, less than 3.25 litres of Diesel in a Petrol GS 450h will in most situations not necessarily be a major problem. Experience has taught us that anything under 3.25 litres (approximately 5% of the fuel tank capacity) is frequently capable of being adequately diluted by means of thoroughly filling the tank with the correct fuel.
      It is relatively rare to encounter a car or truck having difficulties due to lower than 5% incorrect fuel contamination. Be aware that it is very infrequently found - certainly not impossible to find. There are a few motor vehicles that will not endure any amount of contamination at all.
    2. Between 3.25 and 6.5 litres of Diesel in the Lexus (5 to 10%) is really a 50/50 scenario. Our practical experience has shown us that as many drivers get away with it as all those who break down. Any time you are deciding upon whether or not to chance it and basically top it up remember that it is exactly like gambling all of it on black - you've got a 50/50 possibility of it working out.
    3. Anything above 6.5 litres of Diesel in a Petrol GS 450h ought to promptly be drained as your likelihood of getting away with that quantity of contamination is almost certainly lower than one in 50 - definitely big odds.
  2. Put some Diesel in a Petrol Lexus and drove it: Have you observed any kind of performance issues ever since putting the incorrect fuel in the GS 450h? If you have, get it emptied irrespective of the volume of Diesel or even the contamination ratio. Proceeding to drive driving a car that is currently beginning to suffer from the effects of fuel contamination can definitely be responsible for more harm affecting the fuel system.
  3. Would you like assurance?
    Then simply just get it removed. Regardless of the contamination percentage, there is invariably some degree of risk affiliated with driving a Petrol vehicle on Petrol contaminated with Diesel. Likely results of driving a vehicle on the wrong fuel normally include the engine not starting, running lumpy, lack of power, wearing of the high-pressure pump, worn or clogged injectors, and so on. These are a few of the most common Diesel in Petrol symptoms, and should you observe any of them then stop driving and get it removed right now.

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.
