Cadillac Fuel Drain


Filling up with Diesel in a Petrol Cadillac is a fairly typical problem. And exactly what you need to do about it is dependent upon a variety of things. In the event that you want to find out what to do to fix it then read on.
Listed here the key factors to consider when deciding whether or not to have a fuel drain:

  1. What level of Diesel have you put in the Cadillac, considering that the fuel tank capacity of your Cadillac Seville SLS is probably roughly 76 litres?
    1. A tiny amount of Diesel, something like 3.8 litres of Diesel in a Petrol Seville SLS will typically not be a significant problem. Experience has shown us that quantities less than 3.8 litres (which is 5% of the fuel tank) is very often capable of being adequately diluted by totally filling up the tank with the appropriate fuel.
      It is extremely unusual to find an automobile having problems due to under 5% incorrect fuel contamination. Do not forget that it is very rare - in no way impossible to encounter. There are some cars that won't stand any quantity of contamination at all.
    2. Somewhere between 3.8 and 7.6 litres of Diesel in the Cadillac (5 to 10%) is really a 50/50 scenario. Our experience has demonstrated that as many drivers get away with it as all those who don't. Whenever trying to decide whether to chance it and basically top it up remember that it is exactly like wagering everything on black - you've got a 50/50 chance of it being ok.
    3. Anything in excess of 7.6 litres of Diesel in a Petrol Seville SLS must promptly be removed seeing that your probability of getting away with this quantity of contamination is in all likelihood less than one in 50 - definitely long odds.
  2. Put Diesel in a Petrol Cadillac and drove it: Have you spotted any performance concerns since putting the incorrect fuel in the Seville SLS? In that case, get it emptied irrespective of the quantity of Diesel or even the contamination ratio. Still driving a motor vehicle that is currently beginning to suffer the effect of wrong fuel contamination will probably definitely cause more harm being done to your fuel system.
  3. Are you looking for assurance?
    Then get it emptied. Whatever the contamination ratio, there is always some amount of risk in connection with driving a Petrol engine on fuel contaminated with the wrong fuel. Possible final outcomes of driving on the wrong fuel include the motor refusing to start, running unevenly, reduced power, wearing of the high-pressure pump, worn or clogged injectors, and the like. These are a few of the most common Diesel in Petrol symptoms, and in the event that you notice any of them then cease driving and get it drained 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.
