Viables: Petrol in a Diesel Car? Here Is What Happens
Stop. Motor off. Leave the vehicle like that — no second on, no shifting it anywhere. Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever the vehicle has stopped — and no other factor settles that more than these next few minutes do. Anywhere you are in Viables, this is how things go from now.
Minute one: petrol in a diesel, engine off
In this sequence, and before everything else:
- Take your keys out. Even your ignition by itself can prime the fuel system, pulling petrol out of the tank to exactly the components it harms, and so keep the vehicle alone wholly.
- A fuller tank of the same mix is all adding diesel gives you, since it removes nothing. So no more diesel.
- Near passing traffic? Then the hazards come on before anything else, so the car is easy to see.
- Off the pump by hand. At a forecourt, ask the staff to help you roll it away from the petrol pump. Don't fire it up to shift it, however short the distance.
- The first thing we will ask is which fuel went in and about how much — and the receipt says both. Hold on to it.
On the M3, under a mile from Viables, the next junction is the place to come off; elsewhere, the first safe spot to stop. Don't press on to the services. Then go back to stage one.
Every Viables fuel drain starts here: has your engine run?
One answer is what everything after this stage depends on.
If the motor has not run at all:
- All the petrol remains in your tank, and just there.
- Draining and flushing, on the spot, is usually the whole job.
- This is the best position to be in, and the whole reason stage one matters.
Engine run, even briefly?
- Petrol has been pulled from your tank, through the fuel filter and into the fuel lines.
- On a longer run it has got to your high-pressure pump as well as the fuel injectors.
- The farther it went, the bigger the job — the fuel lines, your filter, and now and then more besides.
Diesel keeps the high-pressure fuel pump and your injectors lubricated as it goes through them. Petrol offers them nothing, and that is why the line is drawn there. Nothing is damaged by petrol that's just sitting in a tank. Move that petrol, though, and it wears the very parts that move it.
Before you call about petrol in a diesel around Viables: what our engineers need
A technician that circles against a technician that finds you: a little planning is what separates them.
- Your location: a postcode starting RG22 4 works best.
- Wherever you have parked, the road's name is useful — whether that's Jays Close or somewhere else — and so does the name of a car park.
- Describe a car park by what it serves — the one outside Aldi, for example — and it is far quicker to find.
- Say what the vehicle is — make, model — and confirm it's diesel.
- Which got in counts: AdBlue is a separate job from petrol, and Viables has a page just for that. So say.
- How long the nozzle was in, or the litres from your receipt — whichever gives us how much.
- If it has run, how far and how heavily — and if it has run at all.
- Hire or company car? Some contracts need the owner's go-ahead for the work, and sorting it before our engineers turn up is quicker than after.
Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works as well.
The wait for a Viables fuel drain, and what to do in it
The wait is where well-meant help does the harm. Hold to these.
- Where the vehicle has stopped settles where you wait. Exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the car.
- No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way.
- None of it takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives.
- Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank stays put regardless.
- Ignition stays off. Even for the radio or the windows.
The fuel drain, step by step, after the van gets there
- Fuel, quantity, whether it's run: the answers decide the job, and that is why you get a price after them instead of before.
- That tank is emptied. The contaminated blend comes from the tank.
- Rinsing the lines follows, because a car that ran has petrol past your tank, in the fuel lines themselves.
- Then the filter: changed where there's a serviceable one, cleared where there's not.
- Bleeding your system follows once fresh diesel is in.
- The start-up. With clean diesel in and the system bled, it is started and checked to confirm it runs properly.
Till it runs on new diesel, our technicians stay with it. The vehicle returns to normal driving right away, and lasting damage is very unusual when it has been spotted early.
Once the fuel drain is done: driving around Viables once more
- Nothing special is needed after a start with fresh diesel — ordinary driving will do.
- Watch the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over and call us back.
- An insurer, a fleet manager or a hire firm may ask what was done, so keep the paperwork.
- Next time, check the pump. The label, not the colour of the handle.
