Seat Fuel Drain

ABOUT

Putting Petrol in a Diesel Seat is a fairly typical mistake to make. And what you should do about it hinges on an assortment of things. If perhaps you would like to know what you need to do about it then read on.
Listed below are the key factors to take into account when deciding on whether to have a fuel drain:

  1. What amount of Petrol have you put into the Seat, bearing in mind that the fuel capacity of your Seat Leon TDI is in most cases around 55 litres?
    1. A modest amount of Petrol, something like 2.75 litres of Petrol in a Diesel Leon TDI will more often than not not be a huge problem. Experience has taught us that quantities less than 2.75 litres (which is 5% of the overall fuel tank capacity) is in many instances capable of being sufficiently diluted simply by entirely topping up the remainder of the tank with Diesel.
      It's relatively unusual to come across a car or truck having issues because of below 5% wrong fuel contamination. Keep in mind it is infrequent - definitely not impossible to find. You can get certain cars that don't stand any amount of contamination in the slightest.
    2. Somewhere between 2.75 and 5.5 litres of Petrol in the Seat (from 5 to 10%) is more of a 50/50 situation. Our practical experience demonstrates that as many motorists get away with this as those who break down. When you are deciding whether or not to chance it and just simply fill it up consider that it is exactly like betting everything on black - you have got a 50/50 possibility of it working.
    3. Anything more than 5.5 litres of Petrol in your Diesel Leon TDI ought to promptly be removed seeing as your likelihood of getting away with that level of contamination is certainly below one in 50 - really huge odds.
  2. Put Petrol in a Diesel Seat and drove it: Have you seen any performance concerns after putting the wrong fuel in your Leon TDI? If that's the case, get it emptied no matter the quantity of Petrol or the contamination ratio. Proceeding to drive driving a motor vehicle that is already beginning to suffer the consequences of wrong fuel contamination can only lead to increasing amounts of damage affecting the fuel system.
  3. Do you need assurance?
    You should get it removed. Regardless of the contamination ratio, there is invariably some amount of risk connected to running a Diesel engine on Diesel contaminated with Petrol. Likely implications of driving a car on the wrong fuel include things like the engine refusing to start, running lumpy, decrease in power, wearing of the high-pressure pump, damaged or bunged injectors, and the like. These are some of the commonest Petrol in Diesel symptoms, and in the event that you observe any of them then stop and get it removed as soon as possible.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?

Answer

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 Diesel car on Petrol cause damage to it?

Answer

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 Petrol can I get away with in a Diesel car?

Answer

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?

Answer

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?

Answer

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 Diesel and add some 2-stroke oil?

Answer

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.
