Seat Fuel Drain


Putting Diesel in a Petrol Seat is a very common problem. And its solution depends on various things. If you want to find out what it is best to do about this then continue reading.
Right here are the most crucial variables to to consider when deciding whether to have a fuel drain:

  1. What level of Diesel did you put in to the Seat, taking into consideration that the fuel capacity of your Seat Toledo is usually roughly 55 litres?
    1. A tiny quantity of Diesel, as little as 2.75 litres of Diesel in a Petrol Toledo will normally not really be a big problem. Experience has demonstrated to us that an amount less than 2.75 litres (which is approximately 5% of the total fuel tank capacity) is often capable of being sufficiently diluted simply by entirely filling up the remainder of the tank with Petrol.
      It is rather uncommon to encounter a car suffering from issues because of lower than 5% incorrect fuel contamination. Do not forget that it is very infrequent - definitely not impossible to find. There are actually a number of automobiles that don't stand any level of fuel contamination in the slightest.
    2. Between 2.75 and 5.5 litres of Diesel in the Seat (from 5 to 10%) is really a 50/50 scenario. Our experience has revealed that as many drivers get away with this as those who don't. Any time you are deciding upon whether or not to risk it and simply fill it up consider that it is the same thing as betting your car on black - you've got a 50/50 chance of it working.
    3. Anything more than 5.5 litres of Diesel in a Petrol Toledo ought to as soon as possible be removed as your likelihood of succeeding with that quantity of contamination is probably below one in fifty - really big odds.
  2. Put Diesel in a Petrol Seat and drove it: Have you noticed any performance issues since putting the bad fuel in your Toledo? If that's the case, get it drained regardless of the volume of Diesel or even the contamination percentage. Still running a vehicle that is already beginning to suffer from the consequences of wrong fuel contamination will probably likely lead to more damage affecting the fuel system components.
  3. Do you want peace of mind?
    Then simply just get it removed. No matter the contamination ratio, there is inevitably a certain level of threat associated with running a Petrol engine on Petrol contaminated with the incorrect fuel. Possible results of driving on the incorrect fuel can include the engine refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, worn or clogged injectors, etc. These are several of the most frequently seen Diesel in Petrol signs or symptoms, and should you detect any of them stop and have 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.
