Put Petrol in a Diesel Car in Lea? Don't Start It
If you have not fired up the engine as yet, do not. A drain and nothing else is nearly always what a motor requires while the petrol is still sitting in your tank and the motor has not been started, which is why it is the following few minutes that count, not how much was put in. Petrol in Diesel travels to the car wherever it has stopped in Lea or the remainder of Lincolnshire, on the forecourt, at the roadside or on a driveway, and drains and cleans it there. A single call our way is sufficient: we can explain what follows after this. Do that right away.
Petrol in a diesel: what to do first
- Never crank it. Started all the same? Then do not rely on it. Diesel in a petrol motor typically will not run, so the motorist stops and the harm stops with them. Petrol in a diesel? It starts. It ticks over. It pulls away normally, for a few miles. Most people get that backwards. It is not fine — your fuel system is grinding every mile you drive.
- Two things, diesel: it combusts, and on the way through it keeps the high-pressure fuel pump and injectors oiled. Petrol only does the one. Which is why the ignition is left off as well — flick it on and you often prime the system, and that is petrol exiting that tank for just those parts.
- Topping up gets rid of nothing. It gives you a larger tank of the same mixture, because a diesel fuel system does not accept petrol by percentage in the way that guidance presumes — so never pour diesel on top to water down it. Type is irrelevant too: super unleaded is petrol.
- Wait where you are if you sensibly can. A vehicle that hasn't moved is the simplest one to deal with, and our team would much rather travel to an odd place than have it started. If you're parked on the verge on Gainsborough Road, turn your hazards on then leave it there.
- Before you ring, gather your position. Anything nearest to you with a label on it, plus a postcode that starts DN21 5 — that's what decides whether the technician shows up or circles.
- Dial 0333 366 0103. Anticipate three questions — what went in, approximately how many litres, plus whether the car has been started. Those answers decide whatever comes after.
The run in is what pushed thinned diesel through your pump. Standing still has drawn nothing. Petrol in a diesel Volkswagen Golf, parked at Gainsborough Lea Road all day, rests harmless in that tank while it waits. Phone us first — before your keys go in.
Diesel has to be viscous enough to seal the precision parts it passes through, and petrol dilutes it. That's the full process, and it explains the ordinary Lea Park call: a diesel Mercedes C-Class that travelled out there without complaint and came back down on power, lumpy at idle, maybe smoking a little. A diesel injection system works hydraulically as well as chemically — it needs your fuel to hold pressure, not merely to burn — so when your fuel weakens, pressure that should build and stay built starts leaking past gaps instead, and your engine gets a weaker, later, less even delivery than it was built around. None of that is the motor failing, which is the bit worth hearing: it is the fuel no longer behaving like diesel, and it stops when your fuel is put right.
Pulled off the forecourt, read your receipt, and parked your diesel Dacia Duster up by St Helen a couple of hundred yards later? That's about as well as this goes once the motor has turned. Call us and leave the vehicle off. The short hop truly helps, but it was still a start and a drive, and so diluted fuel has reached the filter and the pump — which is why our engineers rinse your lines rather than only clearing that tank.
New spots are where this occurs most, and the reason is mechanical rather than slapdash: the slimmer petrol nozzle goes into a current diesel filler neck with almost no resistance at all. Topped up near St Mary without thinking, in a diesel Vauxhall Astra you have had for two days? Phone us where you are. Hire and courtesy cars often get driven further before anybody notices, and distance is what determines how much petrol reaches the injectors.
Cleared, not cleared — that is what a diesel Peugeot 208 which got as far as Cornerstone Christian Centre needs. Running a diesel puts the mix into the fuel filter, the fuel lines, your pump and the rail, none of which empties with the tank, and so by now that tank holds the smaller part of the problem.
Can petrol be taken from your diesel on the forecourt?
The job kicks off at the pump, mostly. Quite often the job finishes on site as well. Our technicians work on garage forecourts regularly, with the site's permission, so if you are still at Gulf that is normally where this drain gets done.
Nowhere else other than a forecourt can the mistake be halted with the motor still cold. The few seconds between reading the till receipt and reaching for the key determine how much needs flushing. Anywhere other than the forecourt — a car park, a driveway, a lay-by — your car was fired up and moved to get there, so fuel was sucked from that tank, through the fuel filter then into the high-pressure pump. That means the lines and the filter need rinsing as well as that tank. It is not a calamity, and our engineers can still deal with it where your car is.
Roll the car out of the way if the staff volunteer, and they usually will. The next customer gets by the petrol pump, and that is worth doing. Starting it just for four car lengths? Not a chance.
Parts our vans cover near Lea
As a rural village, Lea has a steady call, while the areas close by go with it on the same round: Knaith Park and Knaith, Park Springs and Gainsborough, Bole.
If yours isn't on this list it doesn't mean we don't come — there are separate pages for nearly all towns around Lincolnshire, and the ones named above are just the nearest neighbours. Call us to check instead of presuming, particularly where you're on the boundary or somewhere the satnav gets wrong.
That map is the area this page covers. Our technicians work by the road, at forecourts, on driveways and in car parks throughout all of that, and your car never needs to move to us.
Stranded on the kerbside in Lea
The opportunity to pull in somewhere sensible does not come to everybody. A common call for us and not an unusual one: realised after setting off, finished up along the verge beside Willingham Road or in a lay-by with the hazard lights on.
Okay right there? Sit with it. Not fine? Climb out and away from it. Never start up your motor to nurse the car somewhere safer — a diesel running on petrol will often oblige, and every mile it obliges for is drawing the mixture further into your fuel system. We'll bring our van to an inconvenient place without any bother, and for the vehicle that's a lot better than carrying on.
So you've driven it? Petrol in a diesel over a few miles
The M180 is the one which counts now, and it lies under 15 miles from Lea. Some distance along, and onto it in the first place: a misfilled diesel will often do both before anything seems wrong. What you get then is seldom a clean stop. Power ebbs away, the idle goes uneven, and there may be some smoke.
The first sensible exit is the one to take. Turn off there, then leave the restarting alone. Long drive? Anything near the under 15 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that reached by the petrol. Say that on the phone, because it affects what goes in the van.
A little about Lea
Lea is a small village in Lincolnshire, situated in the East Midlands region of England, with a population of around 769 people. Lea sits inland, approximately 13 miles from the city of Lincoln, and is characterized by its predominantly detached housing stock. Lea is located near other local places such as Knaith Park and Knaith, and is about 131 miles north of London. Lea has an elevation of around 14 metres above sea level, placing it in a relatively low-lying area of the county.
What we do when our engineers get to you in Lea
- The answers change the work, which is why we ask before quoting: what went in, how much of it, and whether your motor has run.
- The contaminated fuel is pulled from your tank.
- We flush the fuel lines and clean the fuel filter, so what's left in the fuel system is not what created the trouble.
- Fresh diesel goes in, and then the fuel system gets primed.
- It's run with new diesel in it, and our engineers check that it's running smoothly.
Then it's ready to set off. There's no need for a garage at any stage, because the work is all done where the car is, and when it is spotted quickly, lasting damage is very uncommon.
A different matter: AdBlue in a diesel tank in Lea
If what was put in was AdBlue instead of petrol, the opening instruction is unchanged — don't fire it up — but this problem isn't. Petrol does two things to diesel: weakens it, and removes the lubrication the fuel system relies on. Urea dissolved in water, AdBlue, and in a diesel tank that causes corrosion and build-up.
AdBlue removal around Lea has a page of its own with the full story on it, including why it's often the more serious of the two. We cover both.
How much is a petrol-in-diesel drain in Lea?
One price wouldn't be fair here, because this isn't one job. These are the things that change it:
- Started? Driven? Either answer matters more than anything else on this list.
- How much of the wrong fuel went in, judged against how much the tank holds.
- AdBlue or unleaded, whichever went in.
- Whether a van can safely get to the vehicle and work on it, which rests on where your car is.
The vehicle, the quantity, whether it has run — give us those and the answer comes back firm rather than as a range. Car at home, going nowhere, nothing pressing about it — is ideal for that.
Petrol in diesel queries from Lea motorists
Can you do a fuel drain at a petrol station in Lea?
Yes — forecourts are where a good part of this happens. Permission from the site is the condition. Given that, a forecourt like Morrisons is somewhere we are frequently, along with the rest of them locally — so name yours on the call and you will hear if working there is possible.
How much petrol in a diesel is too much?
Litres are not the measure. Proportion is, and much more than either, it matters if anything has been run. Five litres in a nearly empty tank is a distinct matter from five in a full one — but either way, the thing that settles how much work is required is if that mixture has been pulled through your fuel system.
Petrol in my diesel, and I have driven the car
Stop safely. Off. Nothing after that. Not restarting it is the single most valuable thing available to you now. Driving does move the issue out of your tank and into your pump and injectors, yes, and it remains salvageable far more commonly than people expect.
Fuel drains and manufacturer warranties
It isn't a modification, and so a drain then flush carried out correctly does not invalidate a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a disagreement with one, which is another good reason to leave the car turned off.
Could I put some two-stroke in and just drive?
Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol thinned. No. The pump still has to live with it, because your tank still has petrol in it afterwards.
Main dealers and petrol in a diesel
Wherever your car is, our technicians drain and flush it there, so a visit to the main dealer does not come into it.
Still with your vehicle?
Shut off is how it stays.
If you have already driven the vehicle, pull over somewhere sensible, switch it off and leave it off. Cold, parked, going nowhere: that is the best place to be in. Motorists fear this much more than they need to.
Call-out fuel draining in Lea and throughout Lincolnshire — at the kerbside, on the forecourt or at home.
