Lexus Fuel Drain


Putting Diesel in a Petrol Lexus is a well-known mistake. And its solution varies according to various things. If you would like to find out what you have to do to sort it out then please read on.
Listed here are the key variables to keep in mind when deciding whether to have your car drained:

  1. What level of Diesel have you put into the Lexus, taking into account that the fuel capacity of your Lexus IS 250C is in most cases approximately 65 litres?
    1. A modest amount of Diesel, as little as 3.25 litres of Diesel in a Petrol IS 250C will most of the time not necessarily be a massive problem. Experience has proven to us that quantities under 3.25 litres (almost 5% of the overall fuel tank) is generally capable of being completely diluted simply by completely topping the remainder of the tank with the appropriate fuel.
      It's rather rare to come across a vehicle experiencing issues due to lower than 5% incorrect fuel contamination. Be aware that it is very uncommon - not impossible to find. You will discover some vehicles that don't endure any quantity of contamination whatsoever.
    2. Somewhere between 3.25 and 6.5 litres of Diesel in the Lexus (5 to 10%) is a 50/50 situation. Our experience demonstrates that as many drivers get away with this as all those who don't. Any time you're deciding whether or not to risk it and simply fill it up bear in mind that it is exactly like wagering your car on black - you have a 50/50 chance of it working out.
    3. Anything above 6.5 litres of Diesel in your Petrol IS 250C should really right away be drained out seeing that your probability of driving with this level of contamination is in all likelihood lower than one in 50 - extremely big odds.
  2. Put Diesel in a Petrol Lexus and drove it: Have you seen any performance concerns since putting the wrong fuel in the IS 250C? If so, have it emptied regardless of the volume of Diesel or even the contamination ratio. Continuing to run running a vehicle that is now starting to suffer the consequences of fuel contamination will probably typically result in more and more damage being caused to the fuel system components.
  3. Are you interested in peace of mind?
    Then get it drained. Regardless of contamination ratio, there is inevitably some extent of danger linked with running a Petrol motor on fuel contaminated with Diesel. Possible final outcomes of driving a vehicle on the wrong fuel include the engine not starting, running lumpy, loss of power, wearing of the high-pressure pump, worn out or blocked injectors, etc. These are several of the commonest Diesel in Petrol symptoms, and should you notice any of them stop driving and get it removed right away.

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.
