Put Petrol in a Diesel Car in Moor Hall? Don't Start It
Petrol in Diesel drains and cleans wrong-fuelled cars where they stand, on the forecourt, by the roadside or on a driveway, throughout Moor Hall and the remainder of West Midlands. The first thing to do is not to turn on the motor. When the engine has not yet been started and the petrol is still in your tank, a fuel drain is nearly always all it requires, and the following few minutes decide that, not how much got in. Our team shall explain what the next part will be. Phone — that happens before all else.
Petrol in a diesel: what to do now
- Don't fire it up. Turned on anyway? Then never believe it. Diesel in a petrol car generally won't run, so the motorist stops and the damage ends with them. Petrol in a diesel? It starts. It ticks over. It pulls away normally, for a couple of miles. Drivers get that backwards. It is not all right — the fuel system is grinding every mile you cover.
- Flicking the ignition on frequently primes that system, and priming is what moves petrol out of the tank and into the pump and injectors. Those are the components diesel keeps oiled on its way through, before it ignites. Petrol manages the burning and none of the oiling. Leave the ignition alone.
- Do not dilute it. Diesel tipped on top clears nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system accepts petrol. Super unleaded? Still petrol. The type makes no difference.
- Stay still if it is sensible to. Hazards on, engine off, keep it. Wherever you have stopped — the verge on Moor Hall Drive, anywhere — a difficult place for us trumps a started motor, and nothing is simpler for us to handle than a motor that never moved.
- Get your location prepared before you phone. A postcode that starts B75 6 and whatever is nearest to you with a sign on it is the difference between our van arriving and the van circling.
- Three facts determine the full job: the liquid you put in, the rough amount involved, and whether it has been going since. The line is 0333 366 0103.
The journey back would close to double it, for no purpose at all. One commute has already sent a real amount of petrol-thinned diesel through the high-pressure pump of your Volkswagen Golf. So leave the car where it sits. Phone us from the platform if that is handier — no one needs you hovering over the car outside Four Oaks while we get on, and tonight beats finding out on Monday.
Your diesel Nissan Qashqai will have felt completely normal on the way back from Coppice 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 motor and it usually will not run, so the motorist stops and the damage stops with them. Put petrol in a diesel and it starts, idles and pulls away as though nothing has happened — all while your high-pressure pump does its work without the protection the fuel is meant to be providing. Nothing alerts you, because from the driver's seat there is nothing to caution you about. Phone with approximately how far you drove and how hard you worked it; the second one counts more than the first.
Easy job, this one — until someone drives it home. A diesel Audi A4 sitting by The Green House with petrol in the tank loses nothing by standing there overnight, and so leave the car then ring us once it is light. Expect a question about that drive there, though. Short and cold is precisely where petrol battles to burn, and what won't burn can get past the piston rings and into the engine oil.
Stop somewhere sensible, turn off then call us. Happy on the way out to Moor Hall Golf Course, gutless on the way back? Then look at your tank. Petrol weakens diesel; runnier fuel seeps past the precision parts that build injection pressure; and the further your diesel Ford Focus went, the less of that pressure it held.
Hire car or company car? Call them before you ring us — some agreements want the hire firm to sign off the work, and sorting that out first is a great deal quicker than sorting it afterwards. Then call us about the BMW 1 Series near Francis Brett Young 1884-1954, and do not worry that you cannot say how full that tank was. Nearly nobody can, in a vehicle they collected two days ago, and our engineers work it out on site. The reason our technicians ask is that petrol in a diesel does its harm as a share: the same few litres in an almost empty tank is a far stronger mix than in a full one. Petrol is rated on how well it withstands igniting under pressure, which is the opposite of what a diesel needs — so the stronger that mix, the more it knocks, smokes and goes flat.
Pump-side draining for petrol in a diesel
The job starts at a forecourt, typically. Frequently the work ends at one too. We work on garage forecourts routinely, with the site's agreement, and so if you are still at Shell that is generally where this drain happens.
At a forecourt, the mistake gets caught with your engine never run, and nowhere else does it. The few seconds between seeing your receipt and going for the key determine how much needs cleaning. Everywhere other than a forecourt — a car park, a drive, a lay-by — the vehicle was fired up and driven to get there, so fuel was sucked from your tank, through your filter and into your high-pressure pump. That means the fuel lines and your filter need cleaning as well as that tank. It's not a disaster, and our engineers can still sort it out where the car sits.
The attendants will usually offer to wheel the vehicle out from the pump so the next customer can get by. It is worth doing. Moving the car four spaces doesn't merit firing the motor.
Coverage in Moor Hall
Doe Bank, Ley Hill, Four Oaks Park, Mere Green, Ladywood — every one of them on our trips that take us across to Moor Hall itself, a residential suburb.
If yours is not on this list that does not mean we don't come — there are dedicated pages for the majority of places across West Midlands, and the ones named above are just the nearest neighbours. Contact us and check instead of guessing — borders particularly, and wherever the satnav may struggle with.
The patch this page covers is on this map. Every bit of that is ground our engineers work: a kerbside, a forecourt, a private drive, a car park. You do not drive the car anywhere.
Moor Hall: stuck where you parked
A chance to pull in anywhere sensible does not fall to everyone. If you noticed after setting off and finished up along the verge beside Little Sutton Lane, or at a lay-by somewhere with the hazard lights on, that's a normal call for us rather than an odd one.
Whether you remain by the vehicle or step clear of it depends on if staying nearby feels sensible. Never start up your motor to limp it somewhere safer — a diesel running on petrol will frequently oblige, and every mile it obliges for is dragging that mixture further into the system. A technician heading to a tricky place is no problem for us, and it's far better for the vehicle than carrying on.
Petrol in a diesel, and the car has gone
under 3 miles from Moor Hall, the local M6 Toll is what counts here. A misfuelled diesel will often take you onto it and some way along before anything feels wrong, while the symptoms when they come are usually lost power, an uneven idle and smoke rather than a tidy stop.
Come off at the first safe exit, turn off, and do not start the vehicle to move it. On a longer drive — anything near the under 10 miles to the nearest city — assume the mixture has been through the fuel filter, the pump and the injectors, and mention it when you ring. It changes what we bring.
Moor Hall itself
Moor Hall is a suburban area in the West Midlands, situated approximately 7 miles from Lichfield and 103 miles northwest of London. Moor Hall occupies a gentle inland slope at an elevation of around 141 metres, with nearby settlements including Doe Bank and Ley Hill. Moor Hall is characterised by its predominantly detached housing stock, reflecting its development as a residential area. Moor Hall is also close to Four Oaks Park, a nearby recreational space.
When our engineers get to you in Moor Hall: what follows
- Our engineers ask first, quote after. What was put in? How much? Has your motor run? Those answers alter what the work actually is.
- The polluted fuel is drawn from your tank.
- Lines rinsed, filter cleared. Whatever remains after that is not the thing that caused the problem.
- Bleeding your system follows, once fresh diesel is in.
- The engine is turned on and checked to confirm it runs correctly on clean diesel.
After that it's ready to pull away. There's no need for a workshop at any point, as the work is all done where the vehicle is, and when it's noticed soon, permanent damage is very unusual.
A separate job: AdBlue in a diesel tank around Moor Hall
If what got in was AdBlue rather than petrol, the opening rule is the same — never crank it — but this problem is not. Petrol does two things to diesel: thins it, and takes away the lubrication your fuel system relies on. Rust and deposits are what a diesel tank gets instead, since AdBlue is urea in water.
Both are ours. There is a separate Moor Hall page for AdBlue removal, with the detail on it — including the reasons it usually turns out to be the worse of the two.
How much is a petrol-in-diesel fuel drain around Moor Hall?
One number would not be fair here, because this is not one job. These are the things that move it:
- This is the key one: whether your engine has been started, or driven.
- How much of the wrong fuel was put in, weighed against how much that tank holds.
- AdBlue or petrol, whichever got in.
- Whether a van can safely reach your vehicle and work on it, which rests on where your vehicle is.
A clear answer rather than a range is what you get for telling us three things: the vehicle, the quantity, and if it has run. Vehicle at home, going nowhere, nothing urgent about it — is good for that.
Petrol in diesel: frequent questions in Moor Hall
Fuel drains on a Moor Hall petrol station forecourt
Much of what our technicians do takes place nowhere else. So yes. Tell us which one you are at when you call and we will tell you whether our engineers can work there. With the owner's permission we attend Esso and the other forecourts around town routinely.
Is there a safe quantity of petrol in a diesel?
Ratio settles it instead of litres — and more than either, whether the motor has run. What decides how much work is required is whether that mixture has been drawn through the fuel system — because though five litres in an almost empty tank is a different situation from five in a full one, either way that is the query.
Already driven it with petrol in your diesel? What now?
Stop safely. Off. Nothing after that. Driving is what moves the trouble from the tank into your pump and injectors — but it is recoverable a lot more often than drivers fear, and the single most useful thing you can do now isn't restart the vehicle.
My warranty — does a fuel drain void it?
No. Carried out correctly, draining and rinsing 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 a dispute with one, which is another reason to leave it switched off.
Two-stroke oil in that tank, and then home?
No. Two-stroke oil is an old remedy for a distinct fault and it doesn't replace what petrol has weakened. Your pump still has to live with it, as that tank still has petrol in it afterwards.
A main dealer for petrol in a diesel — essential?
You do not need one. The car is drained and cleaned wherever it is, with no need to take it to a franchised dealer.
Is the vehicle still with you?
Leave it shut off.
Switch it off somewhere sensible and keep it off, if you have already driven it. A stationary, cold vehicle is the best position to be in, and this is recoverable from a lot more commonly than drivers fear.
