Yateley: Put Petrol in a Diesel Car?
Petrol in Diesel drains and cleans wrong-fuelled cars where they are, on the forecourt, at the roadside or on a private drive, across Yateley and the remainder of Hampshire. The first thing to do is not to fire up your engine. While the motor has not turned over and the petrol is still sitting in that tank, a fuel drain is nearly always all it takes, and the following few minutes determine that, not how much was put in. Just one ring to us is sufficient: our team shall tell you what happens next. Do it right away.
What to do now about petrol in a diesel
- Feed a petrol motor diesel and it will generally not 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 moves off — fine for a few miles. People have that muddled, which is the bit they get wrong about petrol in a diesel specifically. So never crank it. And having started, don't believe it: the fuel system is wearing as you drive.
- Leave your ignition off also. Diesel has two roles: it burns, and before it burns it greases your injection pump and those injectors. Petrol manages the first and not the second. Flicking the ignition on is frequently sufficient to prime your system, which carries the petrol out of your tank and into precisely those components.
- Don't add diesel on top to thin it. A diesel fuel system won't handle petrol by percentage as that advice assumes, and topping up removes nothing — it just hands you a larger tank of the same mix. The grade makes no difference either: super unleaded is just petrol.
- Sit tight if it's safe to. Hazards on, engine off, keep it. Wherever you have stopped — the verge on Pond Croft, anywhere — an awkward spot for us is better than a started engine, and nothing is easier for us to sort out than a vehicle that never moved.
- Before you ring, work out your location. Anything closest to you with a name on it, plus a postcode that starts GU46 7 — that is what settles whether our van turns up or circles.
- What was put in, approximately how much, plus whether the motor has run — those three details determine the whole call-out. Ring 0333 366 0103 then tell us.
How many miles you drove is what we ask about, not how long your vehicle has been stood — and this is why. Diesel does two jobs on its way through a motor: it burns, and before burning it protects that injection pump and the injectors. Petrol manages the first only. So a fast top-up on the road in, the realisation coming close to eleven, and a diesel Volkswagen Golf sitting at Sandhurst since quarter past eight means those few miles were covered with the pump labouring on a liquid drained of a lot of its protection. Phone us then keep the vehicle right where it sits.
Tell us this much and we can work with it: a diesel Skoda Octavia, a few litres of unleaded in it, two miles or so, turned off at East Euro Market now. Time gone by is not the thing our engineers need. Fuel drawn by the pump is.
Try the drive home from The Royal Oak? No. It will fire up and it will drive off quite happily, which is the trouble — a diesel on a thinned tank acts typically while wearing down the parts the fuel should be lubricating. Leave the Dacia Duster and phone us.
Don't drive it home to buy yourself time. You already have it: nothing gets worse while your car sits, since a diesel Peugeot 208 left outside Church End Green is doing none of what it did on the way there. Your pump has stopped turning.
Hire car? Company car? Ring them before us. Some agreements want the firm to sign off the work, and that's much quicker dealt with up front than after that. Then ring us about the Kia Sportage, the diesel one, near St Peter's Church. Don't worry that you cannot say how full that tank was — almost nobody can two days into a car, and it's something our engineers work out on the spot. The reason for asking: harm from petrol in a diesel is a matter of share. A couple of litres in a nearly empty tank make a far stronger mix than in a full one, and petrol is built to resist the very thing a diesel needs of that, which is igniting when compressed. Stronger blend, more rattling, more smoke, flatter throttle.
Can petrol be drained out of a diesel on the forecourt?
Pumps are where this work mostly kicks off, and where a good portion of that closes. The drain typically gets done there and then. Still on the forecourt at Esso? Given the owner's consent, that's a place we work, and routinely.
Nowhere except the forecourt can the mistake be halted with the engine still cold. The few seconds between reading your receipt and going for the keys decide how much requires rinsing. Everywhere other than a forecourt — a car park, a private drive, a lay-by — your car was switched on and moved to get there, so fuel was pulled from your tank, through the filter then into the high-pressure fuel pump. That means the fuel lines and the fuel filter need cleaning as well as the tank. It is not a disaster, and we can still sort it out where your car stands.
Clear of the petrol pump, the next motorist can get by — so yes, let the attendants help you roll the car. Very much worth it. Cranking it for four vehicle lengths? No.
Service around Yateley
As a riverside town, Yateley gets a frequent call, while the places close by come along on the same run: Cricket Hill and Darby Green, Sandhurst and Frogmore, Little Sandhurst.
Our technicians do come. Those places above are merely the nearest neighbours, and a page is there for nearly all places around Hampshire, and so an absence from the list isn't an absence from the coverage. Presuming is the thing to skip, above all on the boundary or somewhere the satnav fails. Phone to ask.
The map is the area the page includes. We operate at the roadside, on forecourts, on driveways and at car parks throughout all of it, and your car does not need to travel to us.
Yateley: stranded wherever you pulled up
Not everyone gets the opportunity to stop anywhere safe. Hazards going in a lay-by somewhere, or stopped on the verge beside Haydon Place as you realised after setting off — our engineers take that call often enough that it is the ordinary kind.
Clear of your car while it is not wise to sit in it, by it if it is. Every mile a diesel obliges you for on petrol draws the blend further into your fuel system — and oblige it frequently will, which is why the engine does not get restarted to limp somewhere handier. However tricky the spot, it is no problem for us to come to it, and that's a lot better for the car than driving on.
So you've driven it? Petrol in a diesel over a few miles
Here is where your M3 matters, under 3 miles from Yateley. Lost power, a rough idle, smoke: those are the signs when they arrive, instead of a neat stop — and a misfuelled diesel will frequently get you onto it and some way along before anything feels wrong at all.
Get off at the next safe exit, turn off, and do not restart the vehicle to reposition. Presume the worst of that on a long drive. Anything approaching the under 50 miles to the nearest city, and the mixture has been through the fuel filter, through the pump, through the fuel injectors. Say so when you call. What our engineers bring differs.
A little about Yateley
Yateley is a town situated in the north east of Hampshire, on the banks of the River Blackwater. Yateley sits at an elevation of 59 metres, with Cricket Hill to the north and Darby Green to the east. Yateley has a mix of housing types, but detached homes are predominant, and the town is located near the larger town of Sandhurst. Yateley is approximately 31.9 miles from London and 28.7 miles from Winchester, making it a commuter town for those working in the surrounding cities.
The visit around Yateley, step by step
- Our technicians ask first, price after. What got in? How much? Has the engine run? Those answers alter what the work actually is.
- The tainted fuel is drawn from the tank.
- What is remaining in the fuel system should not be what caused the problem, and so the lines get flushed and the filter cleaned.
- Bleeding the system follows, once clean diesel is in.
- The motor is turned on and tested to make sure it runs properly on clean diesel.
Your car is then ready for you to drive away. Lasting damage is very unusual when it has been noticed soon, and as everything is done where your car is, it never has to be taken to a workshop.
AdBlue in a diesel tank around Yateley is a separate job
The problem isn't the same, though the opening rule is — don't fire it up — if what was put in was AdBlue rather than petrol. Petrol does two things to diesel: dilutes it, and strips out the lubrication the system depends on. Rust and build-up are what a diesel tank ends up with instead, since AdBlue is urea dissolved in water.
AdBlue removal in Yateley has a page of its own with the detail on it, including why it is frequently the more serious of the two. We deal with both.
How much is a petrol-in-diesel drain around Yateley?
Our technicians can't put one figure on this page honestly, because this job isn't one job. What changes it:
- This is the key one: whether the engine has been run, or driven.
- Wrong fuel in, against what that tank holds — that ratio.
- The kind of liquid in the tank, unleaded or AdBlue.
- Access: the car's position, and whether working on it there is safe for a van.
The car, the amount, whether it has run — give us those and the answer comes back straight instead of as a range. For your car at home that is going nowhere and is not time-critical, is fine too.
Petrol in diesel: frequent questions in Yateley
At a petrol station in Yateley, can you do a fuel drain there?
Yes, and it's where a good part of this work gets done. Our engineers attend Texaco and the other forecourts nearby routinely, with the site's consent — tell us which one you are at when you call and we'll tell you if our engineers can work there.
Is there a safe quantity of petrol in a diesel?
Proportion settles it instead of litres — and more than either, whether your engine has run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same question in the end: has that mixture been drawn right through, or has it not?
Petrol in my diesel, and I have driven the car
Switch off somewhere safe, then keep it that way after you stop. Driving is what takes the problem from the tank into the pump and injectors — but it is recoverable a lot more frequently than motorists expect, and the single most helpful thing you can do now isn't restart it.
Will a fuel drain void my warranty?
A drain and flush carried out correctly is not a modification and doesn't invalidate a manufacturer's warranty. Another good reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a disagreement with one.
Adding two-stroke oil, then driving home
No. Two-stroke oil is an old fix for a distinct problem and it doesn't restore what petrol has thinned. That tank still has petrol in it later on, and your pump still has to put up with it.
Main dealers and petrol in a diesel
Not at all. We drain and flush your car wherever it is, so there's no need to bring it to a main dealer.
You, and your car, still together?
Leave the car turned off.
Switch it off somewhere safe then keep it off, if you have already driven it. This is recoverable from much more often than drivers assume, and a parked, cold motor is the best place to be in.
