Put Petrol in a Diesel Car in Dalkeith? Don't Start It
Petrol in Diesel drains and cleans wrongly fuelled cars where they stand, on the forecourt, at the roadside or on a drive, all over Dalkeith and the remainder of Midlothian. The very first thing to do is not to turn on the engine. When the motor has not run and the fuel is still sitting in your tank, a fuel drain is almost always all it takes, and the coming few minutes determine that, not how much got in. Contact us and our engineers can tell you what happens after that before you attempt any more.
The first five steps: petrol in a diesel
- Don't crank it. Turned on all the same? Then don't trust it. Diesel in a petrol car typically can't run, and so the driver stops and the wear stops with them. Petrol in a diesel? It starts. It idles. It drives off normally, for several miles. Drivers get that confused. It is not okay — the fuel system is wearing every mile you cover.
- Leave your ignition alone also. Diesel does two roles: it ignites, and before it burns it lubricates the injection pump and those injectors. Petrol manages the first but not the second. Switching your ignition on is frequently all it takes to prime the system, which draws this petrol out of your tank then into just those parts.
- Topping up removes nothing. It gives you a bigger tank of the same mix, because a diesel fuel system won't accept petrol by percentage the way that advice implies — so never add diesel on top to water down it. Grade is irrelevant too: super unleaded is petrol.
- Remain where you are if you sensibly can. A car that hasn't shifted is the easiest one to handle, and our team would much rather drive to an odd location than have it started. If you're stopped on the verge on Lasswade Road, turn those hazards on then leave the car there.
- Before you phone, have your position. Anything nearest to you with a sign on it, plus a postcode beginning EH22 3 — that is what determines whether our van turns up or circles.
- What got in, about how many litres, and if the engine has run — these three replies shape your whole call-out. Ring 0333 366 0103 then tell us.
The run in is what drew weakened diesel through the pump. Sitting still has drawn nothing. Petrol in a diesel Volkswagen Passat, sitting outside Eskbank all day, sits harmless in your tank whilst it waits. Ring us first — before your keys come out.
Our technicians will come out to you, clear the tank, clean those fuel lines and put clean diesel in so you can get home. So if petrol went into the diesel Renault Clio around Dalkeith and you are sat outside Morrisons with a boot full of shopping, call us — and don't crank it again to leave that spot. A mile or so at gentle throttle uses little diesel, so these tend to be the simple ones.
A diesel Nissan Qashqai in the car park by Justinlees Inn holding a tank full of petrol in it is an easy job, right up till somebody drives it home. Leave it there overnight then ring us in the morning. Nothing degrades whilst it sits. What we'll want to know is whether that drive there was short and cold, because that is where petrol is least able to burn correctly — and whatever does not burn can slip past the rings and into the sump.
Switch off where you have stopped, and don't start it to find somewhere better — near St David's or anywhere at all. Clattering, an uneven idle, white smoke and a soft throttle are a wrongly fuelled diesel Peugeot 3008 telling you what's wrong.
What takes place next is the trouble. The engine immediately draws the petrol still sitting in the filter and the feed lines back round through your pump a second time, since draining a tank does nothing about fuel that has already left it. Drain it then put fresh diesel in, a person confident will tell you — and that tip is half right, since do it to a diesel Mercedes E-Class parked up, Dalkeith And Cowdenfoot Collieries Miners Memorial say, and the thing starts, which is what makes it sound reasonable. Ring us instead. Our engineers flush your system and take the fuel filter off where your vehicle has a serviceable one, and that is the difference between the vehicle being put right and the car simply starting.
Pump-side drains for petrol in a diesel
A large portion of this work ends up done at a pump, as that's where it often kicks off. Still at the nearest petrol station? Then that's typically where it gets done. Petrol station forecourts are normal for us, with the consent of the owner.
A filling station is the single place it can be halted before your engine has run. Anywhere else — a car park, a drive, a lay-by — the vehicle was fired up and driven to get there, which means fuel was sucked from the tank, through the fuel filter and into the high-pressure pump. That is not a catastrophe, and our engineers can still sort it out where it is. It does mean the fuel lines and the fuel filter need cleaning as well as that tank, and that is determined by the few seconds between checking your receipt and reaching for the key.
Staff will usually pitch in pushing it clear of the petrol pump, which lets the next motorist get past. Accept the help. Rolling it four lengths doesn't justify firing it.
Will we reach your side of Dalkeith?
Eskbank, Lugton, Newbattle, Lasswade, Eldindean — all of those on our journeys that bring us across to Dalkeith as well, a riverside town.
If yours isn't on this list that does not mean we don't come — there are separate pages for most places in Midlothian, and the ones listed above are merely the nearest neighbours. Assuming is the mistake to avoid, particularly on the boundary or anywhere your phone fails. Phone to check.
Use this map for the ground included on this page. Our technicians work at the roadside, on forecourts, on driveways and in car parks across all of it, and your vehicle doesn't need to come to us.
Kerbside stops around Dalkeith
Not everyone gets a chance to pull in somewhere safe. If you noticed after setting off and finished up by the verge of A6094, or in a lay-by somewhere with your hazards on, that is a routine call for us rather than an unusual one.
Whether you stay by the motor or step away from it turns on whether being there is safe. Don't fire it up to reach a safer spot. It'll go — a diesel on petrol generally obliges — and each mile of obliging draws that blend deeper into the system. We will bring our van to an awkward location without any fuss, and for the car that is a lot better than carrying on.
So you've run it? Petrol in a diesel after some miles
under 10 miles out of Dalkeith, your M8 is what matters here. A misfilled diesel will usually take you onto it and some way along before anything seems wrong, and the signs when they arrive are typically a loss of power, an uneven idle and smoke rather than a clean stop.
Take the next exit that is safe, pull up there, and do not restart it to move it. Long trip? Anything near the under 10 miles to the closest city and you should presume the lot — filter, pump, injectors, all of it arrived at by the contamination. Say that on the phone, as it affects what goes in our van.
A bit about Dalkeith
Dalkeith is a town situated on the River Esk in Midlothian, with a mix of flat and other types of housing. Dalkeith sits at an elevation of 69 metres, close to the city of Edinburgh, which is approximately 6 miles away. Dalkeith is part of the wider Edinburgh urban area, with nearby places including Eskbank, Lugton, and Newbattle. Dalkeith has a population of around 8242 people, making it a significant settlement in the region.
What our engineers do when our technicians get to you in Dalkeith
- The replies alter the work, which is why we ask before pricing: what was put in, how much of it, and whether your engine has run.
- Away comes the polluted mixture.
- Fuel lines are cleaned through and the fuel filter cleaned, leaving nothing in the fuel system that created any of this.
- Fresh diesel goes in, and then the system gets primed.
- It's run with new diesel in it, and our technicians confirm that it is running correctly.
Then it is ready to set off. All of this is done where your car is, so it never has to go to a workshop, and when it has been spotted quickly, lasting damage is very uncommon.
AdBlue in a diesel tank around Dalkeith is a distinct job
If what was put in was AdBlue instead of petrol, the first instruction is the same — never fire it up — but the issue is not. Petrol does two things to diesel: thins it, and strips out the protection your fuel system depends on. AdBlue is urea in water, and in a diesel tank it leads to corrosion and residue in its place.
Our technicians cover both, and AdBlue removal in Dalkeith has its own page with the details — including why it is often the more serious of the two.
Budgeting for a petrol-in-diesel drain in Dalkeith
Truthfully, no single price fits on a page like this. This job differs. Here is what moves it:
- This is the key one: whether the motor has been started, or driven.
- The tank's capacity, set against how much of the wrong fuel got into it.
- The kind of liquid in the tank, petrol or AdBlue.
- Whether a van can safely reach the vehicle and work on it, which hinges on where the car is.
A firm answer instead of a range is what you get for telling us three things: the car, the quantity, and whether it has run. For the car at home that is going nowhere and isn't urgent, works too.
Petrol in diesel queries from Dalkeith motorists
Can you do a fuel drain at a petrol station around Dalkeith?
Yes, and it's where a good portion of this work takes place. Consent from the site is the condition. Given that, a forecourt like Tesco is somewhere we're regularly, along with the rest of them locally — so name yours on the phone and you'll hear whether working there is possible.
Is there a safe quantity of petrol in a diesel?
It depends on the proportion instead of the litres, and a lot more on whether your motor has run. What settles how much work is required is if that mixture has been sucked through your fuel system — since though five litres in an almost empty tank is a different situation from five in a full one, either way that's the query.
Petrol in my diesel, and I have driven it
Turn off somewhere sensible, then keep it that way after you stop. Driving is what takes the issue from your tank into your pump and injectors — but it is fixable far more commonly than drivers expect, and the single most helpful thing you can do now isn't restart the car.
Fuel drains and manufacturer warranties
No. Carried out properly, draining and purging is no change at all, and the warranty from your manufacturer is untouched by it. Running a diesel on petrol is the thing likelier to cause an argument with one, which is another reason to leave the vehicle turned off.
Adding two-stroke oil, then driving home
What petrol has diluted is not replaced by two-stroke oil, which is an old workaround for a distinct fault. So no. Later on? Still petrol in the tank, and a pump that has to cope with the stuff.
Do I need a main dealer for petrol in a diesel?
You do not need one. The car is drained and flushed wherever it is, with no need to take it to a dealership.
Still with your car?
Keep the engine shut off.
Turn it off somewhere safe then keep it off, if you have already driven it. This is recoverable from a lot more often than drivers expect, and a stationary, cold vehicle is the best place to be in.
