Kept Driving With Petrol in a Diesel Vauxhall Omega?
If you have travelled with petrol in a diesel Vauxhall Omega, pull over once it is safe, switch the motor off and keep it off. Caught soon, it only very rarely causes permanent damage, and sorting it out wherever you have stopped is still possible.
Petrol in Diesel comes to wherever your Vauxhall Omega has ended up, empties your fuel tank then cleans the petrol out of your fuel system. It is on clean diesel and running by the time we leave.
Warning signs of petrol in a diesel Omega
It's usually a few miles before the signs show up, as with petrol inside your fuel tank a diesel Omega tends to run as usual to begin with. With petrol or AdBlue inside the tank, these are the ones people tend to notice:
- power drops away, especially when you ask the motor to pull
- the idle turns uneven, or it runs rough
- the exhaust puts out more smoke than usual
- the dash displays warning lamps
- the engine cuts out and may not start again
The receipt will show what was put in, which means you should check it if any of these began after you filled up.
How far wrong fuel in your Vauxhall Omega gets when you drive
Driving is what pulls wrong fuel in your Vauxhall Omega from the tank then on through the filter, the high-pressure pump and your injectors. Till the engine draws it out, it stays where it is. The mixture reaches more of the system the further the Omega is taken, since petrol dilutes the diesel that lubricates the fuel pump and the fuel injectors on its way through them.
So completing the trip is a poorer choice than stopping as soon as you can. Driving a long way on contaminated fuel is what can do damage, and when a motor is stopped soon, draining and cleaning are usually all it needs.
If yours is the Omega 2.5 DTI or another version of the Omega, nothing changes.
Waiting where you have stopped
The Omega doesn't need moving anywhere. The roadside and outside your home are both places we come to, so it does not need restarting or towing.
On a busy road, switch on your hazard lights, then choose somewhere safe to wait clear of the traffic.
Roughly how far you drove, which Omega it is and where you have stopped are the things to mention when you phone 0333 366 0103. Knowing the version on the badge, such as the Omega Caravan 2.2 DTI 16V, is useful as well.
Fuel drain on your Vauxhall Omega after it was driven
There is one step more to a fuel drain on your Vauxhall Omega after it has been driven than to one at the forecourt. No petrol is left between your fuel tank and the engine by the end, which is why your tank is drained first and your fuel lines are then opened and flushed through with your fuel filter. Before our technicians go, the engine is started to check it's running correctly on clean diesel, after the system has been primed.
AdBlue in a diesel Vauxhall Omega that has been driven
If you have AdBlue in a diesel Vauxhall Omega and you have driven on it, the symptoms are usually uneven running, smoke and warning lights, and the car may stall. Sinking to the bottom of the fuel tank, where your fuel pump picks up fuel, AdBlue reaches the fuel line fast, and it does not burn or lubricate. As its water dries, the urea crystallises in the lines and your filter.
AdBlue removal from a diesel Vauxhall Omega after it has run
The fuel lines and the fuel filter have to be freed of the crystals after your tank is emptied, which is what AdBlue removal from a diesel Vauxhall Omega that has been run involves. If the filter needs it, we change it.
Nothing here means switching off or taking out the AdBlue system. It covers liquid in your diesel tank, and a dedicated AdBlue tank your Omega may have is left alone.

Common queries about petrol in a diesel Vauxhall Omega after driving
Is my Omega ruined?
It is very unlikely. Permanent harm is uncommon when the vehicle is stopped soon and the fuel system is emptied and cleaned, and that is what we do where you've pulled up.
Can I drive the car home first?
We'd ask you not to. Tainted fuel gets further into your fuel system with each mile, which means you can leave the Omega where it is while we empty it there, with no need to shift it.
What do I do if it has stalled and will not restart?
Leaving it alone is better than having another go, since each try pulls that blend further through. We start it for you after draining and rinsing it, putting clean diesel in and priming your fuel system.
Does it matter which Omega I have?
There are 8 diesel versions of the Omega, and the badge on the tailgate says which one you have. Knowing that assists us when you call.
Does my insurance cover wrong fuel in my Vauxhall Omega?
Some insurance policies have misfuelling cover, and so it is worth looking at yours after your car is sorted. We still come out either way.
