Already Driven With Petrol in a Diesel Cadillac BLS?
As soon as it's safe, pull over then switch the engine off, and leave it off. Driving on with petrol in a diesel Cadillac BLS just takes the petrol further in. It is very rare for permanent harm to follow when it's caught early, and it can still be sorted out wherever you have stopped.
Once Petrol in Diesel travels out to wherever your Cadillac BLS has stopped, the petrol is cleared from your fuel system and your tank emptied. We go once it's running on clean diesel.
Noticing petrol in a diesel BLS
You may drive a few miles without spotting anything, because petrol in your fuel tank often keeps a diesel BLS driving as usual at first. Motorists normally spot these signs if there is petrol or AdBlue inside the tank:
- power drops away, especially when you ask the engine to accelerate
- it runs roughly, or your idle turns uneven
- the exhaust puts out more smoke than usual
- dashboard warning lights appear
- it cuts out, and then may fail to restart
The receipt shows what went in, so check it if any of these started after you filled up.
Wrong fuel in your Cadillac BLS: what driving on it does
Wrong fuel in your Cadillac BLS stays in the tank until the motor pulls it out, and driving is what takes it through the fuel filter, the high-pressure pump then your injectors. The mix reaches more of your fuel system the further the BLS is driven, because petrol weakens the diesel that protects the fuel pump and your injectors on its way through them.
That is the reason to stop as soon as you can rather than complete the journey. Harm, where it happens, comes from a long drive on contaminated fuel, and a drain and a clean are usually all a car needs when it's stopped early.
It makes no difference if you have the BLS Wagon 1.9 TiD or any other version of the BLS.
Where you've pulled up
The BLS doesn't need getting anywhere. No tow has to be booked and there is no reason to restart it, because we come to it at the roadside or outside your house.
On a busy road, turn on your hazard lights, then choose somewhere safe to wait clear of the traffic.
Before you phone 0333 366 0103, have your whereabouts to hand, along with the distance you drove and which BLS it is. It helps too if the badge shows the version, like the BLS Wagon 1.9 TTiD.
Fuel drain on your Cadillac BLS after it has been driven
Next to a drain on the forecourt, a fuel drain on your Cadillac BLS goes one step further after a drive. We empty the fuel tank first, then open up the fuel lines and then flush them through with the filter, so no petrol is remaining between the fuel tank and the motor. Clean diesel goes in, the fuel system is primed, and our technicians fire up the motor to make sure it runs properly.
When the motor has run with AdBlue in a diesel Cadillac BLS
Uneven running, smoke and warning lamps are the normal signs once you've driven on AdBlue in a diesel Cadillac BLS, and the vehicle might stall. As AdBlue sinks to the base of your fuel tank, where your pump draws its fuel, it's in your fuel line quickly, and it does not burn or lubricate. The urea forms crystals in the fuel filter and the lines as its water dries.
AdBlue removal from a diesel Cadillac BLS
AdBlue removal from a diesel Cadillac BLS that has been run means emptying your tank then clearing the crystals from the lines and the fuel filter, and we replace the fuel filter if it needs it.
Nothing here means switching off or removing the AdBlue system. It deals with fluid in the diesel tank, and any separate AdBlue tank your BLS has is left alone.

The price of a fuel drain on the Cadillac BLS after a drive
The price of a fuel drain on the Cadillac BLS after it's been driven depends largely on how far it went and where it has stopped, and whether it was petrol or AdBlue makes a difference as well. Give us those details in a call and then we can tell you what is involved in the work.
Driven with petrol in a diesel Cadillac BLS: your questions
Has the petrol ruined my BLS?
The likelihood of that is very small. We drain and clean the fuel system wherever you have pulled up, and when the car has been stopped soon, lasting damage is uncommon.
Should I drive it home first?
We would ask you not to. Tainted fuel gets further into your system with every mile, which means you can keep the BLS where it is whilst we empty it there, with no reason to shift the vehicle.
Stalled, and it will not restart: what should I do next?
Please do not try again. Leave it as it is, because each attempt pulls more of the blend through. With it drained and flushed and fresh diesel in, we prime your fuel system and get it started for you.
Which BLS I own: does it matter?
It helps when you call if we know which of the 3 diesel versions of the BLS you have, and the boot badge says.
Does my policy cover wrong fuel in my Cadillac BLS?
Misfuelling cover is offered in some insurance policies, so check yours after your car has been dealt with. Either way, we come out.
