Lexus Fuel Drain


Filling Diesel in a Petrol Lexus is a very common problem. And its remedy depends on several different things. In case you want to find out what you ought to do about this then keep reading.
Here are the key factors to take into consideration when deciding on whether or not to have your car drained:

  1. Exactly how much Diesel did you put in to the Lexus, bearing in mind that the fuel tank capacity of the Lexus LS 400 is most likely roughly 85 litres?
    1. Hardly any Diesel, less than 4.25 litres of Diesel in a Petrol LS 400 will normally not really be a massive problem. Experience has demonstrated to us that quantities under 4.25 litres (about 5% of the overall fuel tank) is often capable of being adequately diluted by completely topping the remainder of the tank with Petrol.
      It's pretty rare to come across a motor vehicle having problems due to below 5% wrong fuel contamination. Please remember it is unusual - certainly not impossible to encounter. You will discover certain vehicles that won't endure any degree of fuel contamination at all.
    2. Between 4.25 and 8.5 litres of Diesel in the Lexus (5 to 10%) is really a 50/50 condition. Our expertise has demonstrated that as many people get away with this as those who break down. When you are trying to decide whether or not to risk it and just simply top it up recognise that it is just like wagering it all on black - you have got a 50/50 chance of it working out.
    3. Anything over 8.5 litres of Diesel in your Petrol LS 400 should right away be removed because your likelihood of succeeding with this quantity of contamination is in all likelihood lower than one in 50 - really huge odds.
  2. Put Diesel in a Petrol Lexus and drove it: Have you detected any performance difficulties ever since putting the bad fuel in the LS 400? If that's the case, have it removed regardless of the volume of Diesel or the contamination ratio. Continuing to drive running a vehicle that is currently starting to suffer from the effect of fuel contamination will likely bring about progressively more harm being caused to your fuel system components.
  3. Are you looking for reassurance?
    Then get it removed. Regardless of contamination ratio, there is invariably some amount of danger affiliated with driving a Petrol engine on fuel contaminated with the wrong fuel. Probable results of driving a vehicle on the incorrect fuel include the motor refusing to start, running unevenly, lack of power, degradation of the high-pressure pump, damaged or bunged injectors, etc. These are some of the most typical Diesel in Petrol signs and symptoms, and in the event that you detect any of them stop and get it drained 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.
