Put Petrol in a Diesel Car in Clerkhill? Don't Start It
If you have not turned on your engine yet, don't. A fuel drain and nothing more is almost always what a vehicle requires while the petrol is still inside your tank and your engine has not run, which is why it's the next few minutes that count, not how much went in. Petrol in Diesel goes to the car wherever it has ended up in Clerkhill or the remainder of Aberdeenshire, on the forecourt, at the roadside or on a private drive, and drains and flushes it there. Ring us so our team shall tell you what follows next before you attempt any more.
What to do now about petrol in a diesel
- As you drive, your pump and the fuel injectors wear down. That is why you don't crank it, and why you never rely on it once it has started. The catch about petrol in a diesel in particular — the bit drivers get wrong — is that it drives off 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 damage with them. This one lets you drive on.
- Two things, diesel: it ignites, and on the way through it keeps the injection pump and injectors lubricated. Petrol only does the one. Which is why the car's ignition stays off too — turn it on and you usually prime that system, and that's petrol leaving that tank for precisely those parts.
- Topping up gets rid of nothing. It leaves you a larger tank of the same blend, since a diesel fuel system won't accept petrol by percentage as that guidance suggests — so do not add diesel on top to weaken it. Octane is beside the point too: super unleaded is petrol.
- Our team would much rather drive to an odd spot than have it started — so if you reasonably can, sit tight. Nothing is quicker to deal with than a car that has not shifted. On the verge on Eden Drive, that means hazards on then keep the car.
- Keep your location ready before you call. A postcode beginning AB42 2 and whatever is closest to you with a sign on it is the difference between a van arriving and the van circling.
- Ring 0333 366 0103. Prepare for three things — what went in, roughly how many litres, plus whether the engine has been started. The answers decide everything that comes after.
Do not drive it home. Petrol-thinned diesel has gone through the high-pressure fuel pump in real quantity on the trip in, and the drive back would more or less double that for nothing at all. Phone — the platform is okay. There's no need to stand over the Renault Clio at the nearest station whilst the work happens, and we'd far rather speak to you tonight than find out on Monday.
The phone call our technicians like runs like this: diesel BMW 3 Series, some litres of unleaded, run a couple of miles, now turned off at Aldi. What we are truly asking is how much fuel the pump has pulled — not how long ago it was.
Your diesel Nissan Qashqai will have seemed entirely usual on the way back from the local primary school. They always do, and that is the catch with petrol in a diesel rather than the other way round. Put diesel in a petrol vehicle and it mostly will not run, so the driver stops and the damage stops with them. Put petrol in a diesel and it fires up, ticks over and pulls away as though nothing has happened — all the while your high-pressure pump works without the lubrication your fuel is meant to be providing. Nothing tells you, since from the driver's seat there is nothing to alert you about. Phone us with approximately how far you drove and how hard you drove it; the second answer matters more than the first.
Pull in somewhere safe, switch off and phone us. Fine on the way out to West Links, sluggish on the way back? Then look at that tank. Petrol dilutes diesel; runnier fuel slips past the precision components that build injection pressure; and the further your diesel Peugeot 208 went, the less of that pressure it held.
Purged, not cleared — that's what a diesel Skoda Superb which got as far as WW1 War Memorial needs. Running a diesel puts the mix into the filter, the fuel lines, your pump and the rail, none of which empties with your tank, so by now that tank holds the smaller part of the damage.
On the forecourt: clearing petrol from your diesel
Forecourts are where the job often starts, and where a big share of that closes. Still at Esso? Then that is normally where it happens. Station forecourts are normal for us, with the agreement of the owner.
The forecourt is the single place the mistake is halted before your engine has started. The few seconds between seeing the receipt and reaching for the keys settle how much needs cleaning. Anywhere other than a forecourt — a car park, a driveway, a lay-by — the vehicle was started and driven to get there, so fuel was sucked from that tank, through the fuel filter then into the high-pressure fuel pump. That means your lines and your filter need rinsing as well as your tank. It's not a disaster, and we can still put it right where the vehicle is.
Move the car out of the way if the attendants suggest it, and they normally will. The next motorist gets past the pump, and that's worth doing. Cranking it for four vehicle lengths? Never.
Will our engineers cover your end of Clerkhill?
Clerkhill is a residential suburb, and so our technicians go out to the town and to the places around it on the usual trips: Grange Gardens, Middle Grange, Meethill, Blackhouse and Coplandhill.
We still come. Those names above are only the immediate neighbours, and a page is there for the majority of places across Aberdeenshire, and so an absence from the list is not an absence from our coverage. Call us and check instead of assuming — borders particularly, and anywhere the satnav tends to misread.
Use our map for the patch shown on this page. Roadside, forecourt, driveway, car park: the lot is ground our engineers work on, and none of it needs the vehicle to travel to us.
Stranded on the kerb anywhere in Clerkhill?
Not everyone finds a decent place to stop. If you noticed after setting off and finished up on the verge beside Copeman Avenue, or at a lay-by somewhere with the hazard lights going, that is a common call for us and not a rare one.
Okay right there? Sit by it. Not fine? Step out and away from it. Every mile a diesel obliges you for on petrol draws the blend further into the fuel system — and oblige it often will, which is why your motor does not get restarted to limp somewhere handier. We'll bring the van to a tricky place without any fuss, and for the vehicle that's a lot better than pressing on.
Already run it? Petrol in a diesel over some miles
This is where your M90 matters, over 50 miles from Clerkhill. Some way along, and onto it in the first place: a wrongly fuelled diesel will usually manage both before anything seems wrong. What you get then is seldom a tidy stop. Power ebbs away, the idle gets lumpy, and there may be some smoke.
Get off at the next sensible exit, turn off, and do not start the car to move it. It changes what our technicians bring, so mention it when you call: on a longer drive — anything approaching the under 50 miles to the nearest city — take it the contamination has been through the filter, your pump and your injectors.

What follows when our engineers get to you around Clerkhill
- The answers shape the work, which is why our technicians ask before giving a price: what was put in, how much of it, and whether your motor has run.
- Our engineers empty that tank of all the tainted fuel.
- Fuel lines are purged through and the fuel filter cleaned, leaving nothing in the system that caused any of this.
- Bleeding the system follows, once clean diesel is in.
- The motor is fired up and checked to make sure it runs properly on new diesel.
That has your car ready to drive away. There's no need for a garage at any stage, since the work is all done where the vehicle is, and when it is spotted soon, lasting damage is very rare.
AdBlue in a diesel tank around Clerkhill is a different problem
Don't crank it: that first instruction applies whether what got in was AdBlue or petrol. What changes is the fault itself. The lubrication a fuel system relies on is taken away by petrol, which dilutes your diesel. Rust and deposits are what a diesel tank gets instead, because AdBlue is urea dissolved in water.
Both are ours. There's a separate Clerkhill page for AdBlue removal, with the details on it — including the reasons it usually turns out to be the worse of the two.
How much is a petrol-in-diesel drain around Clerkhill?
What shifts the figure is set out below, as this job isn't one job and we can't honestly put a single figure on this page.
- Whether your engine has been run or driven. This is the key one.
- How much of the wrong fuel got in, judged against how much your tank can hold.
- Which went in: unleaded or AdBlue.
- Access: the vehicle's position, and whether working on it there is safe for a van.
A clear answer rather than a range is what you get for telling us three things: your car, the amount, and if it has run. Vehicle at home, going nowhere, nothing urgent about it — is ideal for that.
Petrol in diesel: common queries around Clerkhill
Fuel drains on a Clerkhill petrol station forecourt
Yes — forecourts are where a fair part of this happens. Routinely, provided the site agrees: Asda, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that place is something we answer straight away.
How much petrol in a diesel is too much?
Litres aren't the yardstick. Proportion is, and much more than either, it matters whether anything has been run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that mixture been drawn right through, or has it not?
I put petrol in my diesel and drove it. What next?
Somewhere sensible, then stop, then turn off and keep it off. It's salvageable much more frequently than motorists expect, even though driving is what takes the problem from your tank into the pump and injectors — and the single most helpful thing you can do now isn't restart it.
Fuel drains and manufacturer warranties
A manufacturer's warranty withstands a drain and flush done to a proper standard, which is no alteration at all. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Can I just add two-stroke oil and drive home?
No. It belongs to a different issue from a different era, and petrol has weakened something no oil of that kind puts back. Petrol remains in that tank later on, whatever else goes in, and your pump gets no reprieve from it.
A main dealer for petrol in a diesel — needed?
You do not need one. The car is drained and cleaned wherever it is, with no need to take it to a main dealer.
Waiting next to it?
Keep it switched off.
If you have already driven it, pull in somewhere sensible, turn it off then keep it off. This is recoverable from far more often than drivers expect, and a stationary, cold vehicle is the best position to be in.
