Lexus Fuel Drain


Filling Diesel in a Petrol Lexus is a fairly typical mistake to make. And exactly what you need to do about it depends upon an assortment of things. If perhaps you would like to find out what it is best to do to sort it out then stay with me.
Right here are the key factors to to consider when choosing whether to have it drained:

  1. How much Diesel have you put in the Lexus, taking into consideration that the fuel tank capacity of your Lexus Rx 450h is most likely roughly 65 litres?
    1. A tiny amount of Diesel, less than 3.25 litres of Diesel in a Petrol Rx 450h will generally not really be a big problem. Experience has proven to us that an amount less than 3.25 litres (which is close to 5% of the whole fuel tank capacity) is often capable of being adequately diluted through wholly filling the tank with the appropriate fuel.
      It is very rare to find a motor vehicle going through problems because of under 5% wrong fuel contamination. Be aware that it is infrequently found - in no way impossible to encounter. There are a few motor vehicles that will not stand any quantity of contamination at all.
    2. Somewhere between 3.25 and 6.5 litres of Diesel in the Lexus (5 to 10%) is more of a 50/50 scenario. Our expertise has proven that as many people get away with it as those people who break down. When you are deciding on whether or not to risk it and just fill it up bear in mind that it is much like wagering everything on black - you've got a 50/50 possibility of it working out.
    3. Anything above 6.5 litres of Diesel in a Petrol Rx 450h must straightaway be drained seeing that your probability of getting away with this level of contamination is in all likelihood below one in 50 - genuinely huge odds.
  2. Put Diesel in a Petrol Lexus and drove it: Have you noticed any performance concerns since putting the incorrect fuel in the Rx 450h? If so, have it removed irrespective of the quantity of Diesel or even the contamination ratio. Continually driving a car that is starting to suffer the effect of wrong fuel contamination will typically be responsible for progressively more harm affecting the fuel system.
  3. Are you interested in security?
    Then simply just get it drained. Regardless of the contamination ratio, there is always some amount of danger affiliated with operating a Petrol motor on Petrol contaminated with Diesel. Probable results of driving on the wrong fuel can include the motor refusing to start, running unevenly, loss of power, degradation of the high-pressure pump, worn or clogged injectors, and so on. These are some of the most common Diesel in Petrol signs or symptoms, and should you recognise any of them then stop and have it drained immediately.

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.
