Stripes: Petrol in a Diesel Car? Here Is What Happens
Stop, and keep the engine off — not on, and not for a moment to shift the vehicle. Petrol in a diesel that hasn't been run is typically a drain plus a flush, done right where your car stands, and what you do in the next few minutes determines that more than anything else. What follows is the sequence from this point, anywhere around Stripes you are.
Minute one: petrol in a diesel, motor off
Do these before anything else, in this order.
- The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what draws petrol out of the tank towards the components it damages.
- A fuller tank of the same mixture is all topping up gives you, since it takes out nothing. So no extra diesel.
- Hazard lights on. If you are anywhere close to moving traffic, make your car easy to see before you do anything else.
- Off the pump by hand. On a forecourt, ask the attendants to help you roll the car away from the pump. Don't fire it up to move it, however short the distance.
- Keep the receipt: the grade and roughly how much are written on it, and they are what our engineers ask about first.
If you were still on the move when you noticed, pull over somewhere sensible rather than pushing on for the services — on the M6, under 3 miles from Stripes, that means the next junction. Step one comes next.
Every Stripes fuel drain starts here: has your motor run?
What happens next rests on one answer, and only one.
Engine never run at all?
- The petrol is still in the tank and nowhere else.
- Draining and flushing, on the spot, is normally all of it.
- Stage one matters for precisely this reason: it is the best place to be in.
If it's been started, even for a second:
- The fuel lines and your filter already hold petrol pulled out of the tank.
- A longer run carries it right through to your high-pressure pump and the injectors.
- The job grows with the mileage — lines flushed, filter sorted, sometimes more.
Diesel keeps the high-pressure pump and the fuel injectors oiled as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. Nothing is damaged by petrol that's only sitting in a tank. Move the petrol, though, and it grinds down the very parts doing the moving.
What to have ready when you call about petrol in a diesel from Stripes
A little planning is the difference between a technician that finds you and a van that circles.
- CA4 0 and the rest of the postcode is the ideal way to start telling us where you are.
- The road or the car park. A road name is a help — Peter Gate, or wherever you have pulled up.
- What a car park serves is the easiest way to find it, and so say the landmark — such as the one outside Co-op Food.
- Say what your car is — make, model — and check it's diesel.
- What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Stripes, so say which.
- Roughly how much — in litres from your receipt, or by how long the nozzle stayed in.
- Has it run? If so, tell us how far it went, and how it was driven.
- Whose car it is. Some hire or company contracts want the owner to approve the work, and that is easier settled before our technicians get there than after.
Call 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use .
While you wait for a fuel drain around Stripes
Hold to these: well-intended help does the damage during the wait.
- Where the vehicle has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the vehicle.
- Not to roll it a couple of yards, not to check it is all right, not for a passer-by's kindness: nobody starts it.
- Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts that petrol.
- No home-made emptying. Siphoning petrol into a can by the kerbside is hazardous, and it leaves your fuel that has by now gone beyond your tank.
- The ignition stays off. Even for the radio or the windows.
When the van gets there: your fuel drain, step by step
- First, three queries: which fuel was put in, the amount, and has it run? Those answers shape this job, and so our price follows them.
- Your tank is drained. The contaminated blend comes out of that tank.
- Your lines are cleaned. If it ran, the petrol has moved beyond that tank, and the lines are carrying it.
- Where your car has a usable filter, it is replaced; otherwise, cleared.
- The system is primed with clean diesel.
- Our engineers fire it up only after clean diesel has gone in and primed your system, then confirm that it is running correctly.
Only once it is running on new diesel do our engineers leave. It is very unusual for a car noticed quickly to be left with lasting damage, and normal driving resumes right away.
After the fuel drain: back on the road in Stripes
- Drive normally. There is nothing special to do after it's been started on clean fuel.
- Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle stumbling: pull over then call us back.
- The work may come up later with a hire company, an insurer or a fleet manager. Keep the documents.
- The handle's colour is not the guide to go by next time — the label on the petrol pump is.
