Seat Fuel Drain


Putting Diesel in a Petrol Seat is a fairly typical mistake to make. And its remedy hinges on a number of things. Assuming you want to find out what it is best to do about this then please read on.
Listed below are the main variables to think about when choosing whether or not to get a fuel drain:

  1. What amount of Diesel did you put in to the Seat, considering that the fuel capacity of the Seat Altea is most likely approximately 55 litres?
    1. A small amount of Diesel, less than 2.75 litres of Diesel in a Petrol Altea will more often than not not really be a significant problem. Experience has shown us that an amount less than 2.75 litres (about 5% of the fuel tank) is usually able to be sufficiently diluted simply by entirely filling the remainder of the tank with Petrol.
      It's highly unusual to encounter a car or truck having problems due to less than 5% wrong fuel contamination. Keep in mind that it's infrequently found - certainly not impossible to find. There are actually some automobiles that won't stand any quantity of fuel contamination whatsoever.
    2. Anywhere between 2.75 and 5.5 litres of Diesel in the Seat (5 to 10%) is more of a 50/50 condition. Our expertise has demonstrated that as many motorists get away with this as those people who don't. Whenever you are deciding on whether or not to risk it and just simply fill it up recognise that it is the same thing as betting your car on black - you have got a 50/50 possibility of it being ok.
    3. Anything above 5.5 litres of Diesel in your Petrol Altea should really straight away be drained out because your likelihood of succeeding with that level of contamination is in all likelihood less than one in fifty - definitely big odds.
  2. Put Diesel in a Petrol Seat and drove it: Have you spotted any kind of performance troubles after putting the wrong fuel in the Altea? If so, get it emptied regardless of the volume of Diesel or the contamination percentage. Continually driving an automobile that is currently beginning to suffer the consequences of fuel contamination will probably just be responsible for increasing amounts of damage being done to the fuel system components.
  3. Are you interested in security?
    You should get it removed. Regardless of contamination ratio, there is invariably some extent of risk resulting from driving a Petrol motor on fuel contaminated with Diesel. Likely implications of driving a vehicle on the incorrect fuel include the engine refusing to start, running lumpy, loss in power, wearing of the high-pressure pump, damaged or clogged injectors, etc. These are some of the most common Diesel in Petrol warning signs, and if you notice any of them then stop and get it removed right away.

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.
