Put Petrol in a Diesel Car in Ashmore Lake? Don't Start It
If you have not turned on your engine yet, do not. A fuel drain and nothing more is almost always what a motor needs while the fuel is still inside your tank and the engine has not yet run, which is why it is the following few minutes that count, not how much got in. Petrol in Diesel travels to your car wherever it has stopped in Ashmore Lake or the remainder of West Midlands, on the forecourt, by the roadside or on a drive, and drains and flushes it there. Contact us before all else starts, and you will see what comes from there.
What now? Petrol in a diesel, step by step
- While you drive, your pump and the injectors wear. That's why you don't crank it, and why you don't trust it once it has started. The trick about petrol in a diesel specifically — the bit people get wrong — is that it pulls away fine for the first mile or two. Diesel in a petrol motor normally won't run at all, which stops the driver and stops the wear with them. This one lets you keep going.
- Leave your ignition alone also. Diesel has two tasks: it combusts, and before it ignites it protects your high-pressure pump and the injectors. Petrol manages the first but not the second. Flicking the car's ignition on is often enough to prime the system, which draws the petrol out of the tank then into just those parts.
- Do not tip diesel on top to thin it. A diesel fuel system won't tolerate petrol by percentage in the way that advice assumes, and topping up clears nothing — it simply gives you a larger tank of the same blend. The type makes no difference either: super unleaded is just petrol.
- We would much rather travel to an odd spot than have it started — so if you safely can, stay put. Nothing is simpler to sort than a motor that has not shifted. On the verge on Himley Close, that means hazards on then leave the car.
- Before you call, work out your whereabouts. Anything closest to you with a label on it, plus a postcode that starts WV12 4 — that's what decides whether the technician turns up or circles.
- Phone 0333 366 0103. Tell us what got in, roughly how many litres, and if your car has run. These three replies decide your whole visit.
At the forecourt: draining petrol from a diesel
A big chunk of the job ends up finished at a pump, as that is where it often begins. Still at the nearest petrol station? Then that's generally where it gets done. Petrol station forecourts are normal for us, with the agreement of the station.
The forecourt is the only setting it can be stopped before the engine has started. The few seconds between reading the till receipt and going for the key determine how much needs cleaning. Anywhere other than a forecourt — a car park, a driveway, a lay-by — the car was switched on and driven to get there, so fuel was drawn from your tank, through your filter then into the high-pressure fuel pump. That means your lines and the fuel filter require rinsing as well as that tank. It's not a disaster, and we can still sort it out where the car sits.
Staff will usually chip in pushing it clear of the petrol pump, which lets the next motorist get past. Accept the assistance. Shifting the car four bays doesn't merit starting the engine.
We are in car parks like the one outside Nisa Extra all the time, and it's almost never the fuel that complicates them. It is the bay. Vehicles both sides. Trolleys stacked up behind. Occasionally a height limit at the way in, which determines if our van reaches you at all. So say how boxed in you are when you ring, and which way your car is pointing. If there's no room to work beside the Renault Megane, our technicians shift it without your engine. That's not pedantry over a handful of seconds: starts prime things, blend comes out of the tank toward the pump, and a car moved twice for a nicer bay is silently a worse job than one no one touched.
Nothing tells you, since from behind the wheel there is nothing to be warned about. The diesel Skoda Octavia will have felt completely usual on the way back from Pool Hayes Primary School, and they all do — which is the snag with petrol in a diesel rather than the reverse. Diesel in a petrol motor generally refuses to run, stopping the motorist and stopping the damage with them. Petrol in a diesel starts, idles, moves off as though nothing had happened, and all the while the pump works without the lubrication its fuel is supposed to supply. Tell us about how far, and how hard. The harder counts more.
What we'll want to know is whether the trip there was short and chilly, as that's where petrol is least likely to burn fully — and what does not burn can get past the rings and into the engine oil. Right up to the moment someone drives it home, a diesel Peugeot 308 parked in the car park outside Pool Hayes carrying a tank of petrol in it is a simple job. Nothing degrades while it stands, so park it there overnight then phone us in the morning.
Hire car or company car? Call them before you phone us — some contracts want the hire firm to sign off the work, and sorting that out first is a great deal quicker than sorting it later on. Then call us about the Dacia Duster close to Short Heath Methodist Church, and don't worry that you cannot say how full your tank was. Almost nobody can, in a motor they picked up two days ago, and our engineers work it out there. The reason we ask is that petrol in a diesel does its harm as a proportion: the same few litres in a nearly empty tank is a far stronger mixture than in a full one. Petrol is rated on how well it resists igniting under pressure, which is the opposite of what a diesel needs — so the stronger that mix, the more it rattles, smokes and goes flat.
What happens next is the issue. The motor straight away draws the petrol still waiting in the fuel filter and the feed lines back round through the pump a second time, because draining a tank does nothing about fuel that has already left it. Drain it and put fresh diesel in, somebody confident will tell you — and that suggestion is half right, as do it to a diesel BMW X1 parked up, Furzebank Worship Centre say, and the thing starts, which is what makes it sound sensible. Phone us instead. Our technicians flush your circuit and take the filter off where the vehicle has a workable one, and that's the difference between the car being fixed and your car simply starting.
Service in Ashmore Lake
Spring Bank, Wellington Place, Little London, Lane Head, Short Heath — every one of them on our trips that take us over to Ashmore Lake too, a residential suburb.
If yours is not on that list that does not mean we don't come — there are pages for most places around West Midlands, and the ones listed above are merely the nearest neighbours. Contact us and enquire instead of assuming — county lines above all, and anywhere your phone tends to misread.
That map shows the patch the page covers. Our technicians work roadside, on forecourts, on driveways and in car parks throughout all of that, and the car does not need to come to us.
Stuck by the kerbside anywhere in Ashmore Lake?
Some people get no safe spot to pull over whatsoever. Set off, then twigged? Landed on the verge beside Alton Avenue, or sat in some lay-by with the hazards flashing? That is a normal call here. Not a rare one.
Okay there? Remain beside it. Not fine? Move out and away from it. Don't fire up your motor to limp it somewhere handier — a diesel running on petrol will often oblige, and every mile it obliges for is pulling that mix further into your fuel system. We'll bring the van to an inconvenient location without any trouble, and for the vehicle that's far better than pressing on.
Already run it? Petrol in a diesel over some miles
This is where the M6 comes into it — under 3 miles from Ashmore Lake. It will usually take you onto it, and some way along, before you feel a thing. Then it is some smoke, a rough idle and power draining away — not a tidy stop. Wrongly fuelled diesels seldom give you one of those.
Pull off at the next safe exit, switch off, and never start the car to move it. Suppose the worst of that on a long drive. Anything near the under 5 miles to the closest city, and the mixture has been through the fuel filter, through your pump, through your injectors. Say so when you call. What our engineers bring differs.

Our call-out around Ashmore Lake, step by step
- Our engineers find out what was put in, how much, and whether your engine has run. The replies shape the work, which is why our technicians ask before giving a price.
- Our technicians clear your tank of all the contaminated fuel.
- What is left in your system should not be what started the issue, so the fuel lines get purged and the fuel filter cleaned.
- Your system gets primed, on fresh diesel.
- The engine is turned on and checked to make sure it runs properly on fresh diesel.
That leaves it ready to set off. There is no need for a garage at any point, as the work is all done where the car is, and when it is noticed soon, lasting damage is very unusual.
Ashmore Lake AdBlue removal is a separate job
AdBlue rather than petrol? Then the first rule is unchanged — your motor remains off — whereas the fault underneath it is a separate one altogether. Petrol does two things to diesel: dilutes it, and removes the lubrication your fuel system depends on. AdBlue is urea dissolved in water, and in a diesel tank it brings corrosion and deposits in its place.
AdBlue removal around Ashmore Lake has a page of its own with the detail on it, including why it is usually the more serious of the two. Our engineers deal with both.
How much is a petrol-in-diesel fuel drain in Ashmore Lake?
What shifts the price is set out below, as this job is not one job and our engineers cannot truthfully put a single price on this page.
- Started? Driven? Either answer matters more than anything else on this list.
- How much of the wrong fuel was put in, against how much your tank holds.
- AdBlue or petrol, whichever got in.
- Access: the car's position, and whether working on it there's safe for our van.
Tell us the car, the amount and whether it has run, and you'll get a straight answer instead of a range. Not urgent, with the vehicle at home and going nowhere? Then does the job.
Things our technicians hear about petrol in diesel around Ashmore Lake
At a petrol station around Ashmore Lake, can you do a fuel drain there?
Yes — forecourts are where a big portion of this gets done. Often, provided the site agrees: JET, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that spot is something our technicians answer on the spot.
How much petrol in a diesel is too much?
Whether the engine has run matters much more, though the ratio counts too, rather than the litres. What determines how much work is needed is whether that mix has been drawn through the system — because though five litres in a nearly empty tank is a separate situation from five in a full one, either way that's the question.
I drove the vehicle after putting petrol in my diesel. Now what?
Somewhere safe, then stop, then turn off and leave it off. It is fixable far more often than drivers fear, even though driving is what moves the issue from the tank into the pump and injectors — and the single most helpful thing you can do now is not restart it.
My warranty — does a fuel drain void it?
A drain and flush carried out properly is not a modification and doesn't invalidate a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Two-stroke oil in your tank, and then home?
No. Two-stroke oil is an old remedy for a distinct fault and it doesn't restore what petrol has thinned. Petrol stays in that tank after that, whatever else goes in, and the pump gets no break from it.
Does petrol in a diesel have to go to a main dealer?
No. Our technicians drain and clean your car wherever it is, so there is no need to bring it to a main dealer.
Still with the car?
That engine remains off.
Turn it off somewhere sensible then leave it off, if you have already driven it. A still, cold motor is the best place to be in, and this is recoverable from much more often than people expect.
