Put Petrol in a Diesel Car in Bishopston? Don't Start It
If you have not started the engine as yet, don't. A fuel drain and nothing else is nearly always what a motor needs while the petrol is still sitting in that tank and the engine has not been started, which is why it is the coming few minutes that matter, not how much got in. Petrol in Diesel goes to the car wherever it has stopped in Bishopston or the rest of Bristol, on the forecourt, at the roadside or on a private drive, and drains and cleans it there. Phone before all else begins, so you will learn what comes next.
What to do now about petrol in a diesel
- Do not start the vehicle — and don't rely on it when it fires up. This is the part most people have wrong about petrol in a diesel specifically. A petrol motor given diesel typically just cannot run, so the motorist stops and the damage stops with them. A diesel fed petrol typically starts, ticks over and moves off perfectly well for a couple of miles. It isn't all right. It is grinding your fuel system whenever you drive.
- Two things, diesel: it burns, and on the way through it keeps your high-pressure pump and injectors lubricated. Petrol only handles the one. Which is why the car's ignition stays off as well — turn it on and you frequently prime that system, and that is petrol leaving the tank for just those components.
- Topping up clears nothing. It leaves you a larger tank of the same mixture, because a diesel fuel system does not cope with petrol by percentage as that guidance implies — so do not put diesel on top to water down it. Type is irrelevant too: super unleaded is petrol.
- Stay still if it is sensible to. Hazards on, ignition off, keep the car. Wherever you have stopped — the verge on Cranbrook Road, anywhere — an odd spot for us is better than a started diesel, and nothing is easier for us to handle than a car that never moved.
- Before you dial, gather your location. Anything next to you with a name on it, plus a postcode that starts BS6 7 — that is what settles whether the technician turns up or circles.
- What was put in, about how much, and whether the car has run — those three facts settle the full call-out. Call 0333 366 0103 then tell us.
Pump-side drains for petrol in a diesel
Pumps are where the work often starts, and where a good portion of it finishes. Still at EG Bishopston Services Gas Refill? Then that is typically where it happens. Station forecourts are everyday for us, with the permission of the station.
A forecourt is the one setting the mistake is spotted before your motor has run. We can still sort it out where it sits, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been fired up and driven there, and that sucked fuel through the fuel filter then into your high-pressure pump, all the way from your tank. None of that is a disaster, but the flush then has to reach past that tank to the fuel lines and the fuel filter, and the few seconds between checking the receipt and going for your key are what decide that.
Staff will usually pitch in pushing it away from the petrol pump, which lets the next motorist get past. Welcome the offer. Four car lengths is not worth a restart.
Petrol in your BMW 3 Series, and it takes diesel? Shopping in the boot, you at Costcutter, somewhere in Bishopston? Then phone, and leave the engine out of it — not even to leave the bay. A technician comes to you. Tank emptied, fuel lines cleaned, fresh diesel in, and home you go. Easy throttle over a mile pulls little, and so these are often the easy cases.
Three answers determine much of the work: what was put in, about how much, and whether your engine has run since. We ask for those answers when we get to your car in the car park outside Bristol Flyer. Then the contaminated mix comes out of the tank, your lines are flushed, and where your Ford Focus has a replaceable filter, it comes off. After clean diesel is in and your system primed, our engineers start the engine and check it runs properly before you drive away.
Pull over somewhere safe, turn off then phone us. Fine on the way out to Kings Lawn Tennis Club, gutless on the way back? Then look at that tank. Petrol thins diesel; runnier fuel seeps past the tightly fitted components that build injection pressure; and the farther the diesel Mercedes C-Class drove, the less of that pressure it held.
Draining your Audi A3, changing the fuel filter where there is a serviceable one, purging the fuel lines, putting fresh fuel through the full system: that is this job, and it is shaped by the worst of that waiting in your lines rather than in the tank by this point. Three things help when you call from close to Saint Bonaventure's Parish Hall & Business Centre — which side the filler is on, whether a van can park next to without blocking the road, and whether your engine has run since you filled up. On-street is the commonest place we work, so the spot itself is rarely the issue. A narrow parking space is better than a vehicle driven somewhere more handy.
Drain it then put new diesel in — that is the suggestion you'll get, generally from somebody certain, and it is only half right. Do exactly that to a diesel Vauxhall Insignia close to St Bonaventure's Catholic Church and it would start, which is what makes the advice sound sensible. What happens next is the issue: the engine immediately draws the petrol still resting in the filter and the feed lines straight back through the pump, as draining a tank does nothing about fuel that has already left it. Phone us instead. Our technicians flush your system and take the filter off where the vehicle has a serviceable one, which is the difference between your car being fixed and the car simply starting.
Parts we serve in Bishopston
Redland, Westbury Park, Henleaze, Montpelier, Cotham — every one of these on our journeys that take us out to Bishopston too, a residential suburb.
If yours isn't on the list that does not mean we don't come — there are separate pages for most locations in Bristol, and the ones mentioned above are merely the nearest neighbours. Near the boundary, or somewhere your satnav misreads? Contact us and check rather than assuming.
The area this page covers is on our map. Every bit of it is territory we serve: a kerbside, a forecourt, a private drive, a car park. You never drive your car anywhere.
Roadside breakdowns across Bishopston
Not everyone gets a sensible place to pull over. If you noticed after setting off and finished up by the verge on Claremont Avenue, or at a lay-by somewhere with your hazards flashing, that is a common call for us and not an unusual one.
Whether you remain beside your car or move clear of it rests on whether sitting nearby is sensible. Don't restart it to reach a nicer place. It will go — a diesel on petrol normally obliges — and each mile of obliging draws the mixture deeper into your fuel system. A van coming to an inconvenient spot is no problem for us, and it's much better for the vehicle than carrying on.
Already driven it? Petrol in a diesel after some miles
under 3 miles from Bishopston, the M32 is what counts now. It will often take you onto it, and some way along, before you feel a thing. Then it's smoke, a lumpy idle and power draining away — not a tidy stop. Misfilled diesels seldom give you one of those.
Don't restart it to move it. Come off at the next safe exit then turn off. Presume the worst of that on a long trip. Anything near the under 3 miles to the closest city, and the contamination has been through the filter, through your pump, through your injectors. Tell us when you call. What our technicians bring changes.
Bishopston itself
Bishopston is a suburban area located just north of Bristol city centre, at an elevation of around 48 metres above sea level. Bishopston sits inland, approximately 1.5 miles from Bristol, and is surrounded by other suburban areas such as Redland, Westbury Park, and Henleaze. Bishopston is characterised by its predominantly semi-detached housing stock, which reflects the typical residential development of the area. Bishopston has a population of around 12,031 people, according to recent estimates.
What follows when our engineers get to you around Bishopston
- The replies change the work, which is why we ask before giving a price: what was put in, how much of it, and whether the motor has run.
- Out flows the polluted fuel.
- Fuel lines are cleaned through and your filter cleared, leaving nothing in the fuel system that caused any of this.
- Bleeding the system follows, once fresh diesel is in.
- After it is started, our technicians confirm it runs smoothly on clean diesel.
From there, you're ready to drive away. Everything is done where the vehicle is, so it never has to go to a garage, and when it has been spotted soon, long-term damage is very uncommon.
A different job: AdBlue in a diesel tank in Bishopston
Don't crank it: that first step stands whether what went in was AdBlue or petrol. What differs is this fault itself. Diluted diesel, and no lubrication left for your fuel system that relies on it. That's petrol. Rust and residue are what a diesel tank ends up with instead, because AdBlue is urea dissolved in water.
Often the more significant of the two, AdBlue — and the detail sits on its own Bishopston page. Both are ours to deal with.
What a petrol-in-diesel drain will cost around Bishopston
What moves the price is laid out below, as this job is not one job and our engineers can't truthfully put a single figure on this page.
- Started? Driven? Either answer counts more than anything else on this list.
- How much of the wrong fuel got in, set against how much the tank can hold.
- AdBlue or petrol, whichever went in.
- Where your vehicle is, and if our van can safely reach and work on it.
The vehicle, the quantity, whether it has run — give us those and the answer comes back clear instead of as a range. For your car at home that is going nowhere and is not time-critical, is fine too.
Bishopston motorists ask us these about petrol in diesel
Can you do a fuel drain at a petrol station around Bishopston?
Yes, and it is where a fair part of this work takes place. Our technicians work at EG On The Move and the other forecourts around town routinely, with the site's consent — tell us which one you are at when you ring and we will tell you whether we can work there.
How much petrol is too much for a diesel?
Whether the motor has run matters far more, though the ratio counts too, rather than the litres. Five litres in a nearly empty tank is a separate situation from five in a full one — but either way, the thing that settles how much work is required is whether that mix has been drawn through your fuel system.
Petrol in my diesel, and I have driven the vehicle
Pull in somewhere sensible, switch off, and leave it off. Driving takes the trouble along — out of your tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting the vehicle.
My warranty — does a fuel drain void it?
A drain and flush carried out properly is not a change and does not void a manufacturer's warranty. What's likelier to start a disagreement is a diesel that has been run on petrol. One more good reason for your engine to stay off.
Can I just add two-stroke oil and drive home?
Two-stroke oil solves a separate problem, and an old one at that. Nothing it does puts back what petrol diluted. No. The pump still has to put up with it, as that tank still has petrol in it later on.
Does petrol in a diesel have to go to a main dealer?
Wherever the vehicle is, our technicians drain and flush it there, so a drive to the main dealer does not come into it.
You, and your car, still together?
Keep it switched off.
If you have already driven it, stop somewhere sensible, switch it off then leave it off. Cold and parked, a car is in the best position available — and drivers fear this a lot more than the recovery rate warrants.
