Cadillac Fuel Drain


Filling up with Diesel in a Petrol Cadillac is a usual mistake to make. And what you should do about it will depend on a few things. In case you would like to know what it is advisable to do to sort it out then stay with me.
Let us discuss the most crucial factors to consider whenever figuring out whether to get a fuel drain:

  1. What amount of Diesel have you put in the Cadillac, keeping in mind that the fuel capacity of your Cadillac xLR is most likely approximately 68 litres?
    1. A tiny quantity of Diesel, something like 3.4 litres of Diesel in a Petrol xLR will generally not really be a significant problem. Experience has shown us that an amount under 3.4 litres (close to 5% of the fuel tank volume) is generally able to be adequately diluted by means of entirely filling the rest of the tank with the correct fuel.
      It is quite rare to come across a car suffering from difficulties because of under 5% incorrect fuel contamination. Remember that it is very rare - definitely not impossible to find. There are a number of automobiles that don't stand any amount of fuel contamination at all.
    2. Anywhere between 3.4 and 6.8 litres of Diesel in the Cadillac (from 5 to 10%) is a 50/50 scenario. Our experience has shown that as many drivers get away with it as those people who don't. Whenever you are trying to decide whether to chance it and simply fill it up remember that it is much like wagering all of it on black - you have got a 50/50 possibility of it working.
    3. Anything over 6.8 litres of Diesel in your Petrol xLR must promptly be removed seeing as your likelihood of getting away with this level of contamination is certainly less than one in 50 - extremely long odds.
  2. Put some Diesel in a Petrol Cadillac and drove it: Have you noted any performance troubles ever since putting the incorrect fuel in your xLR? In that case, get it emptied regardless of the volume of Diesel or even the contamination ratio. Still running a car that is beginning to suffer the effects of fuel contamination will just result in progressively more damage being done to the fuel system components.
  3. Are you interested in reassurance?
    Then get it emptied. Regardless of contamination percentage, there is always some extent of threat connected to driving a Petrol motor on Petrol contaminated with the incorrect fuel. Likely implications of driving on the wrong fuel normally include the motor not starting, running unevenly, decrease in power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are a few of the most frequently seen Diesel in Petrol signs and symptoms, and if you detect any of them stop driving and get it removed right away.

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.
