Already Driven With Petrol in a Diesel Subaru Trezia?
Once it is safe, pull over then switch the motor off, then leave it off. Running on with petrol in a diesel Subaru Trezia just carries the petrol further in. Where you've stopped, we can still put it right, and harm that lasts is very uncommon when it's caught early.
When Petrol in Diesel comes out to wherever your Subaru Trezia has stopped, the petrol is cleaned out of the system and the fuel tank drained. We go once it's running again on fresh diesel.
Symptoms of petrol in a diesel Trezia
To begin with, petrol in your fuel tank often changes very little to how a diesel Trezia drives, and the signs show up a few miles further on. If the fuel tank has petrol or AdBlue in it, people usually spot these:
- the motor lacks power, particularly whenever you ask it to pull
- rough running, or an uneven idle
- there is more smoke than usual from the tailpipe
- dashboard warning lights come on
- after it stalls, it might not restart
Your receipt shows what went in, which means you should check it if one of these started after you fuelled up.
How far wrong fuel in your Subaru Trezia goes when you drive
Till the motor pulls it out, wrong fuel in your Subaru Trezia remains in the tank, but driving pulls it on to your filter, and then into your high-pressure fuel pump and the injectors. As diesel flows through the injectors and your fuel pump it protects them, but petrol dilutes it, which is why the Trezia spreads that blend further into the fuel system the further it is driven.
That is the reason to stop as soon as you can rather than finish the trip. Harm, where it occurs, comes from a long journey on contaminated fuel, and draining and cleaning are usually all a motor needs if it is stopped early.
Staying where you've pulled up
The Trezia does not need taking anywhere. The side of the road and outside your house are both places we come to, and so it doesn't need starting or a tow.
With your hazards on, stand away from the traffic somewhere safe when the road next to you is fast.
About how far you travelled, which Trezia it is and where you have pulled up are the things to mention when you call 0333 366 0103. It helps too when the badge shows the version, such as the Trezia 1.4D.
Fuel drain on your Subaru Trezia when you have driven on it
Next to a drain on the forecourt, a fuel drain on your Subaru Trezia goes one step further after driving. Once the fuel tank has been emptied, the lines are opened up and rinsed through along with the fuel filter, which leaves no petrol anywhere from your fuel tank to the motor. The fuel system is primed after clean diesel has gone in, then the engine is started to check it runs smoothly.
AdBlue in a diesel Subaru Trezia that has been driven
Rough running, smoke and warning lamps are the normal signs after you have driven on AdBlue in a diesel Subaru Trezia, and the car might then stall. Sinking to the bottom of your fuel tank, where the pump picks up fuel, AdBlue gets into the fuel line fast, and it doesn't burn or lubricate. As its water dries, the urea crystallises in your lines and your fuel filter.
AdBlue removal from a diesel Subaru Trezia: what it involves
The fuel lines and your filter have to be cleared of the crystals after the fuel tank is emptied, which is what AdBlue removal from a diesel Subaru Trezia that has been run means. If the filter needs it, we replace it.
Only the diesel tank is dealt with here. If your Trezia has an AdBlue tank of its own, it is left alone, and nothing here means taking out or turning off the AdBlue system.
The Subaru Trezia fuel tank capacity and its engines
42 litres is the size of the diesel tank on every version of the Subaru Trezia in our figures.
Costing a fuel drain on the Subaru Trezia after a drive
The distance travelled and where it is now count most towards the price of a fuel drain on the Subaru Trezia after a drive, and so does whether it was AdBlue or petrol. Give us those details in a call and we can tell you what's involved in the work.
Petrol in a diesel Subaru Trezia: common questions after driving
Will my Trezia be ruined?
It is very unlikely to be. If your car is stopped soon, draining and cleaning your fuel system is what we do wherever you have stopped, and harm that lasts is rare after that.
Is it OK to drive it home first?
We would sooner you didn't. Tainted fuel reaches further into your system with every mile, so leave the Trezia where it is while we empty it there, with no need to move it.
Stalled, and it will not restart: what should I do next?
Trying again draws more of the blend through with every attempt. Please leave the vehicle as it is. We start it for you after draining and rinsing it, putting clean diesel in and priming the system.
Insurance and wrong fuel in my Subaru Trezia: am I covered?
We still come out whatever your policy says, and some do offer misfuelling cover, so checking yours once your car is dealt with is worthwhile.
