Wilford: Put Petrol in a Diesel Car?
With that tank still holding the petrol and the engine not yet turned over, almost every job takes only a drain, so keep your engine off. That result is determined in the minutes immediately after filling up, and not by the amount that was put in. All over Wilford and the rest of Nottinghamshire, Petrol in Diesel drains your car and flushes it where it is, whether at a roadside, on a drive or at a forecourt. Contact us and our engineers can explain what happens after that before you try anything else.
Petrol in a diesel: what to try now
- Give a petrol engine diesel and it will typically refuse to run at all, so the motorist stops there and so does the damage. Feed a diesel petrol and the car starts, it ticks over, it drives off — fine enough for a couple of miles. Most people have that backwards, which is the thing they get wrong about petrol in a diesel in particular. So never start the vehicle. And if started, never rely on it: the fuel system is wearing whenever you drive.
- Two jobs, diesel: it ignites, and on the way through it keeps your high-pressure pump and injectors greased. Petrol only does the one. That is why the ignition stays off too — switch it on and you commonly prime your system, and that is petrol leaving your tank for exactly those parts.
- Do not dilute it. Diesel poured on top takes out nothing, so all you have is more of what was already there, because percentage is not how a diesel fuel system accepts petrol. Super unleaded? Still petrol. The grade makes no difference.
- Sit tight if it is wise to. Hazards on, ignition off, leave it. Wherever you have stopped — the verge on Wilford Lane, anywhere — an odd location for us trumps a started diesel, and nothing is easier for us to sort than a car that never shifted.
- Keep your whereabouts ready before you ring. A postcode starting NG11 7 and whatever is next to you with a name on it is the difference between our van arriving and our van circling.
- What got in, approximately how many litres, and if the car has started — the three details determine your whole job. Dial 0333 366 0103 then tell us.
Nothing about the time since has lost you anything. Fuel sitting in a tank is idle, and so a diesel Volkswagen Passat sitting at Nottingham this morning is no worse at five than it was at nine — what drew thinned diesel through the pump was the drive in. Phone us before you go to collect it.
Easy, these ones, and the reason is the distance: a mile at gentle throttle draws little fuel. Petrol into a diesel BMW 3 Series somewhere in Wilford, a boot full of shopping, and you stranded outside Co-operative Food — phone us. Getting out of the space is never worth another start. That tank gets cleared where it waits, your fuel lines purged, clean diesel in, and you get home.
Every restart primes the fuel lines and drags more petrol through the fuel filter then into the pump. So a misfilled diesel Mercedes C-Class on the zig-zags outside South Wilford Endowed CofE Primary School is a hassle, whereas the same motor started three more times to be helpful is a fuel system instead of a tank. A passer-by will urge you to move it out of the gateway and sort it out later. Don't. Stay put, let them moan, and phone us.
Hire car or company car? Ring them before you ring us — some contracts want the hire firm to sign off the work, and sorting that out first is a great deal faster than sorting it after that. Then ring us about the Vauxhall Astra near Nottingham Outlaws, and do not worry that you cannot say how full that tank was. Nearly no one can, in a vehicle they collected two days ago, and our technicians work it out on site. The reason we ask is that petrol in a diesel does its damage as a share: 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 mixture, the more it rattles, smokes and goes flat.
No warning light exists for this, which is why cars in that position normally get driven a second time before anyone calls. Don't be one of them. The throttle went limp and the idle turned lumpy after a couple of streets, and your diesel Ford Kuga is now resting by Dave Eastwood Sports Ground (Pelican Colts FC). Softness there means fuel that cannot build pressure fully rather than an engine packing up. Turn off. Phone us.
Pump-side draining for petrol in a diesel
A fair part of the work is completed at the pump, since that's where it mostly kicks off. The drain usually happens there and then. Still on the forecourt at BP? Given the site's permission, that is a place our engineers work, and regularly.
Before the engine has started — a garage is the single place it gets caught. Fuel sucked out of the tank and through the filter, right to the high-pressure fuel pump, is what happens when the engine is fired up and the car is moved to where it is now: the car park, the drive or the lay-by, anywhere other than the forecourt. So the flush covers your filter and the fuel lines together with that tank. That's still not a catastrophe, and our technicians sort it out where your car is. What decides it is whether the key was turned in the seconds after the receipt was checked.
Staff will generally pitch in pushing it clear of the petrol pump, which lets the next driver get through. Take the offer. Cranking it just to shift four car lengths is not.
Do we cover your corner of Wilford?
These same journeys take us to Meadows, West Bridgford, Dunkirk, Old Lenton and Clifton as well as Wilford, which is a village.
There are separate pages for nearly all towns in Nottinghamshire, and the ones mentioned above are merely the immediate neighbours — so yours being absent from this list means nothing about if our engineers come. Guessing is the thing to resist, above all on a boundary or anywhere the satnav goes wrong. Phone to ask.
Check the map for the patch shown here. We operate by the road, on forecourts, on driveways and in car parks over all of it, and your car never needs to come to us.
Wilford: stuck wherever you pulled up
The chance to pull in somewhere sensible does not fall to everyone. A common call for us and not an odd one: noticed after setting off, finished up by the verge on Clifton Lane or at a lay-by with your hazards flashing.
Stay by the car if it is sensible to sit in it, and out of the vehicle when it is not. Every mile a diesel obliges you for on petrol drags the mix further into the fuel system — and oblige it often will, which is why your engine doesn't get restarted to limp somewhere better. We'll bring the van to a tricky place without any fuss, and for the vehicle that is much better than pressing on.
Run it already? Pull in, and check below
This is where the M1 comes into it — under 10 miles away from Wilford. Some way along, and onto it in the first place: a misfuelled diesel will frequently manage both before anything feels wrong. What you get then is rarely a clean stop. Power ebbs away, the idle gets lumpy, and there may be some smoke.
Pull off at the next safe junction, switch off, and do not restart the car to reposition. Presume the worst of that on a long drive. Anything near the under 3 miles to the closest city, and the contamination has been through the filter, through your pump, through the injectors. Tell us when you ring. What our technicians bring differs.
A bit about Wilford
Wilford is a village situated on the banks of the River Trent in Nottinghamshire, with a mix of old and new housing including many detached homes. Wilford lies close to the city of Nottingham, being only 2.1 miles away, and is near other local places such as Meadows and West Bridgford. Wilford has a population of around 1696 people and is located at an elevation of 31 metres above sea level. Wilford is also within easy reach of major cities, with London being approximately 107.3 miles away.
Our call-out around Wilford, step by step
- Our technicians ask first, quote after. What got in? How much? Has your engine run? Those answers alter what the work really is.
- That tank gets cleared of it.
- Our technicians rinse the lines and clear the fuel filter, so what's remaining in the fuel system is not what caused the issue.
- We pour fresh diesel in and bleed the system.
- We start the car and make sure it runs properly on fresh diesel.
That leaves the car ready to pull away. There is no need to go to a garage at any stage, since the work is all done where your car is, and when it's spotted early, permanent damage is very rare.
AdBlue in your diesel tank instead, around Wilford?
Do not start it: that opening rule stands whether what was put in was AdBlue or petrol. What differs is the problem itself. The lubrication a fuel system relies on gets stripped away by petrol, which weakens your diesel. AdBlue is urea dissolved in water, and in a diesel tank it leads to rust and deposits in its place.
Our engineers deal with both, and AdBlue removal in Wilford has its own page with the details — including why it is usually the more serious of the two.
Paying for a petrol-in-diesel drain in Wilford
One figure would not be fair here, since this isn't one job. These are the things that move it:
- Started? Driven? Either answer counts more than anything else on this list.
- Wrong fuel in, against what your tank holds — that ratio.
- Which was put in: unleaded or AdBlue.
- Where the car is, and whether a van can safely get to and work on it.
A straight answer rather than a range is what you get for telling us three things: the car, the quantity, and whether it has run. Vehicle at home, going nowhere, nothing time-critical about it — is ideal for that.
Petrol in diesel queries from Wilford drivers
I'm on a forecourt in Wilford. Can you drain the car here?
Yes, and it is where a fair part of this work gets done. Consent from the site is the condition. Given that, a forecourt like Asda is somewhere we are often enough, along with the rest of them locally — so name yours on the phone and you'll hear if working there is possible.
Is there a safe amount of petrol in a diesel?
It hinges on the proportion rather than the litres, and a lot more on whether your engine has run. What decides how much work is required is if that blend has been pulled through the system — because though five litres in an almost empty tank is a separate case from five in a full one, either way that is the query.
Already driven it with petrol in the diesel? What now?
Somewhere sensible, then stop, then switch off and leave it off. Not restarting it is the single most helpful thing available to you now. Driving does shift the problem out of your tank then into your pump and injectors, yes, and it remains salvageable far more often than people fear.
Is a fuel drain going to void my warranty?
No. Carried out correctly, emptying and purging is no alteration 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 good reason to leave the vehicle switched off.
Two-stroke oil in that tank, and then home?
No. Two-stroke oil is an old fix for a different fault and it doesn't restore what petrol has weakened. Afterwards? Still petrol in that tank, and a pump that has to put up with the stuff.
A main dealer for petrol in a diesel — essential?
There's no need to bring it to a dealership, as we drain and flush the vehicle wherever it is.
Is the car still with you?
Turned off is the way the car stays.
Driven it already? Then somewhere sensible, stop, turn off, and no restarting the car afterwards. Cold, still, going nowhere: that's the best place to be in. People fear this much more than they need to.
