Lexus Fuel Drain


Filling Diesel in a Petrol Lexus is a regular error. And its remedy varies according to various factors. If perhaps you would like to know what to do about this then read on.
Right here are the key factors to be aware of whenever deciding on whether or not to have a fuel drain:

  1. What level of Diesel did you put in the Lexus, considering that the fuel tank capacity of the Lexus LS 430 is probably roughly 84 litres?
    1. A small amount of Diesel, as little as 4.2 litres of Diesel in a Petrol LS 430 will quite often not really be a major problem. Experience has taught us that quantities less than 4.2 litres (which is almost 5% of the total fuel tank) is quite often capable of being adequately diluted by means of thoroughly topping the rest of the tank with Petrol.
      It's extremely rare to encounter an automobile suffering from issues with below 5% incorrect fuel contamination. Be aware that it is very uncommon - in no way impossible to find. You can get a few automobiles that will not endure any level of fuel contamination in the slightest.
    2. Somewhere between 4.2 and 8.4 litres of Diesel in the Lexus (from 5 to 10%) is a 50/50 condition. Our working experience has proven that as many drivers get away with this as those people who break down. When deciding on whether or not to risk it and just simply top it up recognise that it is the same as gambling all of it on black - you will have a 50/50 possibility of it working.
    3. Anything above 8.4 litres of Diesel in a Petrol LS 430 ought to right away be drained seeing that your probability of driving with this level of contamination is undoubtedly lower than one in 50 - seriously big odds.
  2. Put Diesel in a Petrol Lexus and drove it: Have you observed any performance problems as a result of putting the wrong fuel in the LS 430? In that case, get it emptied irrespective of the volume of Diesel or the contamination ratio. Continually running a motor vehicle that is currently beginning to suffer from the effects of wrong fuel contamination can typically be responsible for even more harm being done to the fuel system components.
  3. Would you like reassurance?
    You should get it removed. Regardless of the contamination percentage, there is always a certain level of risk connected to operating a Petrol engine on Petrol contaminated with Diesel. Likely final outcomes of driving on the wrong fuel normally include the engine refusing to start, running lumpy, loss of power, degradation of the high-pressure pump, worn out or blocked injectors, etc. These are a few of the most frequently seen Diesel in Petrol warning signs, and if you observe any of them then stop and have it drained 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.
