Seat Fuel Drain


Putting Diesel in a Petrol Seat is a common mistake to make. And exactly what you have to do about it will depend on a variety of things. Assuming you want to know what you need to do about it then please read on.
Here are the main variables to consider whenever deciding whether or not to have your car drained:

  1. Exactly how much Diesel did you put into the Seat, considering that the fuel tank capacity of the Seat Arosa is probably roughly 34 litres?
    1. A tiny amount of Diesel, something like 1.7 litres of Diesel in a Petrol Arosa will more often than not not be a massive problem. Experience has demonstrated to us that quantities less than 1.7 litres (about 5% of the total fuel tank capacity) is usually capable of being adequately diluted by means of wholly topping the rest of the tank with Petrol.
      It is rather rare to come across a vehicle experiencing problems because of under 5% wrong fuel contamination. Remember that it is very infrequent - definitely not impossible to find. You can get certain cars that won't stand any level of contamination whatsoever.
    2. Somewhere between 1.7 and 3.4 litres of Diesel in the Seat (5 to 10%) is really a 50/50 scenario. Our working experience has shown us that as many people get away with it as all those who don't. Whenever deciding on whether or not to risk it and just simply fill it up remember that it is exactly like betting everything on black - you have a 50/50 chance of it working.
    3. Anything above 3.4 litres of Diesel in a Petrol Arosa ought to right away be removed seeing that your likelihood of driving with that amount of contamination is certainly below one in 50 - seriously big odds.
  2. Put some Diesel in a Petrol Seat and drove it: Have you noted any performance concerns as a result of putting the incorrect fuel in your Arosa? If you have, get it emptied no matter the volume of Diesel or even the contamination ratio. Proceeding to drive driving an automobile that is now starting to suffer from the effects of wrong fuel contamination will probably likely result in more damage being caused to the fuel system.
  3. Would you like peace of mind?
    You should get it drained. Whatever the contamination ratio, there is invariably some amount of risk associated with running a Petrol motor on Petrol contaminated with Diesel. Probable results of driving a car on the incorrect fuel can include the engine not starting, running lumpy, loss of power, wearing of the high-pressure pump, damaged or clogged injectors, and so forth. These are a few of the commonest Diesel in Petrol signs or symptoms, and in the event that you detect any of them then stop driving and get it drained right now.

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.
