Lexus Fuel Drain


Putting Diesel in a Petrol Lexus is a regular error. And its solution depends upon several things. Assuming you would like to find out what you need to do about it then keep reading.
Listed below are the key factors to take into consideration whenever determining whether to have the car drained:

  1. Exactly how much Diesel have you put into the Lexus, bearing in mind that the fuel tank capacity of your Lexus GS 300 is usually around 80 litres?
    1. A tiny quantity of Diesel, something like 4 litres of Diesel in a Petrol GS 300 will typically not necessarily be a major problem. Experience has proven to us that anything less than 4 litres (which is almost 5% of the overall fuel tank volume) is sometimes able to be completely diluted by completely filling up the tank with Petrol.
      It's quite rare to come across a car or truck having issues due to below 5% incorrect fuel contamination. Please remember it's unusual - definitely not impossible to encounter. You can get a few motor vehicles that will not stand any quantity of contamination whatsoever.
    2. Somewhere between 4 and 8 litres of Diesel in the Lexus (from 5 to 10%) is a 50/50 situation. Our expertise demonstrates that as many motorists get away with this as those who don't. Any time you're trying to decide whether to risk it and simply top it up bear in mind that it is exactly like gambling it all on black - you will have a 50/50 possibility of it being ok.
    3. Anything in excess of 8 litres of Diesel in a Petrol GS 300 ought to straight away be removed seeing that your likelihood of succeeding with this amount of contamination is certainly less than one in fifty - genuinely big odds.
  2. Put some Diesel in a Petrol Lexus and drove it: Have you spotted any kind of performance concerns since putting the wrong fuel in your GS 300? If that's the case, get it removed irrespective of the amount of Diesel or the contamination ratio. Continually running a vehicle that is already starting to suffer from the effects of fuel contamination will only cause progressively more damage being done to your fuel system components.
  3. Would you like reassurance?
    In that case get it drained. Whatever the contamination ratio, there is always some extent of threat associated with driving a Petrol vehicle on Petrol contaminated with the wrong fuel. Probable implications of driving a car on the wrong fuel include the engine not starting, running lumpy, decrease in power, wearing of the high-pressure pump, worn out or bunged injectors, and so on. These are some of the most typical Diesel in Petrol signs or symptoms, and if you recognise any of them then stop and get it removed 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.
