Put Petrol in a Diesel Car in Upper Craigie?
With your tank still carrying the fuel and the motor not yet started, nearly every job needs only a drain, so leave the motor off. That outcome is determined in the minutes straight after filling up, rather than by the amount that got in. Across Upper Craigie and the rest of Perth and Kinross, Petrol in Diesel drains the car and flushes it where it is, whether at a roadside, on a drive or at a forecourt. Contact us so our technicians shall explain what happens from here before you attempt any more.
The first five minutes: petrol in a diesel
- Never start the car. Turned on anyway? Then never trust it. Diesel in a petrol car generally cannot run, and so the motorist stops and the harm halts with them. Petrol in a diesel? It starts. It ticks over. It drives off happily, for several miles. Drivers get that backwards. It's not all right — your fuel system is grinding every mile you cover.
- Flicking the ignition on often primes the system, and priming is what carries petrol out of the tank and into your pump and injectors. Those are the parts diesel keeps greased on its way through, before it ignites. Petrol handles the burning and none of the lubricating. Leave your ignition off.
- Topping up clears nothing. It leaves you a bigger tank of the same mix, since a diesel fuel system does not handle petrol by percentage in the way that advice assumes — so do not pour diesel on top to weaken it. Type is irrelevant too: super unleaded is petrol.
- A motor that has never moved is the simplest one to handle, and so wait where you are if you reasonably can. Parked on the verge on Glenlyon Road? Hazards on, and keep it there. A difficult spot works for us better than a started diesel.
- Before you call, get your location. Anything next to you with a label on it, plus a postcode starting PH2 0 — that is what settles whether our van shows up or circles.
- Dial 0333 366 0103. Say what got in, about how many litres, plus if the engine has fired. These three details settle the full visit.
How far you travelled is what we query, not how long the vehicle has been sitting — and here is why. Diesel performs two roles on its way through an engine: it burns, and before burning it greases the high-pressure fuel pump and the injectors. Petrol handles the first only. So a hurried fill-up on the road in, the penny dropping around eleven, and a diesel Volkswagen Passat sitting at Perth since quarter past eight shows those couple of miles were travelled with your pump working on a liquid stripped of much of its protection. Phone and keep it exactly where it stands.
We are in car parks like the one at Tesco all the time, and it is rarely the fuel that complicates them. It is that bay. Motors both sides. Trolleys stacked up behind. Occasionally a height barrier at the entrance, which determines if a van reaches you at all. So say how boxed in you are when you ring, and which way the vehicle is facing. If there is no space to work next to that Renault Clio, our engineers shift it without the engine. That isn't fussiness over a handful of seconds: starts prime things, fuel comes out of your tank toward your pump, and a car shifted twice for a better spot is quietly a harder job than one no one touched.
Twenty to nine. By the local primary school. Late already, and the receipt in your hand shows unleaded. Switch the hazards on, leave the ignition alone, then call us. You could think three miles is nothing, in your BMW 3 Series or anything else — except that fuel is metered on demand, and a drive taken in a rush demands a great deal of it.
A diesel Peugeot 308 parked in the car park by The Abbotsford holding a tank of petrol in it is a straightforward job, right up until someone drives it home. Leave it there overnight and phone next morning. Nothing degrades whilst it stands. What we'll ask is whether that drive there was brief and cold, since that's where petrol is least able to burn properly — and what does not burn can get past the piston rings then into the engine oil.
No dashboard light exists for this, which is why motors in that position normally get driven once more before anybody rings. Please don't be one of them. The throttle went dead and the idle turned lumpy after a few streets, and your diesel Kia Sportage is now waiting near St Mary Magdalene's. Deadness there means fuel that cannot build pressure fully instead of an engine giving up. Turn off. Call us.
Pump-side draining for petrol in a diesel
Much of this job begins at a forecourt, meaning a large share of that ends up done on site. The drain normally happens right there. Still on the forecourt at Shell? Given the site's consent, that is a spot our technicians work, and regularly.
At a forecourt, the mistake is halted with your engine never started, and nowhere else manages that. The few seconds between seeing the receipt and reaching for the key settle how much needs rinsing. Anywhere other than the forecourt — a car park, a driveway, a lay-by — the vehicle was started and moved to get there, so fuel was drawn from your tank, through the fuel filter then into your high-pressure pump. That means the lines and the fuel filter need rinsing as well as the tank. It is not a catastrophe, and we can still deal with it where the car sits.
Roll the vehicle out of the way if the attendants volunteer, and they generally will. The next motorist gets by the pump, and that is worth doing. Four car lengths isn't worth the risk.
Coverage around Upper Craigie
Upper Craigie is a residential suburb, and our team are out to the town and to the areas around it on the usual rounds: Moncreiffe, Friarton, Craigie, Barnhill and Scoonieburn.
Not on this list? It means nothing. The names above are only the closest few, and nearly all towns in Perth and Kinross have a page of their own somewhere on this site. Assuming is the habit to resist, especially on a border or anywhere a satnav fails. Contact us to ask.
The ground the page spans sits on the map. Your car never needs to move to us. Our technicians work throughout all of that — roadside, forecourts, driveways, car parks.
Upper Craigie: stuck wherever you pulled up
A chance to stop anywhere suitable doesn't come to everyone. A normal call for us instead of an unusual one: realised after setting off, finished up by the verge on Craigie Road or in a lay-by with the hazard lights flashing.
Whether you wait by the vehicle or move away from it rests on if staying in it looks sensible. Don't fire it up to get to a better place. It will go — a diesel on petrol generally obliges — and each mile of obliging pulls that mixture deeper into the system. We'll bring our van to a tricky location without any fuss, and for your car that is much better than driving on.
A few miles on petrol in a diesel: what next?
Your M90 is the one which matters now, and it sits under a mile from Upper Craigie. It will often take you onto it, and some way along, before you notice a thing. Then it's some smoke, an uneven idle and power ebbing away — not a tidy stop. Misfuelled diesels rarely give you one of those.
Take the next junction that is sensible, pull up there, and never start the vehicle to reposition. Presume the worst of that on a long drive. Anything near the under a mile to the nearest city, and the contamination has been through the filter, through the pump, through the injectors. Say so when you call. What we bring differs.
Where's Upper Craigie?
Upper Craigie is a suburban area situated on the banks of the River Tay in Perth and Kinross, with a mix of semi-detached housing and local amenities. Upper Craigie lies close to the city of Perth, which is approximately 0.9 miles away, and is near other nearby places such as Moncreiffe and Friarton. Upper Craigie has a relatively low elevation of around 14 metres above sea level, reflecting its riverside setting. Upper Craigie is home to a population of around 3829 people, living in a predominantly residential area.
When our engineers arrive with you in Upper Craigie: what follows
- Our engineers check what got in, how much, and if your motor has run. The replies alter the work, which is why our engineers ask before giving a price.
- Out goes the contaminated fuel.
- Lines cleaned, filter cleared. Whatever is left after that is not the thing that created the trouble.
- Our engineers put new diesel in and bleed the fuel system.
- The motor is turned on and checked to be sure it runs smoothly on new diesel.
From there, you're ready to drive away. Our engineers do everything wherever the vehicle has come to a stop, which means it never has to be taken to a garage, and if it has been noticed early, it is very unusual for there to be lasting damage.
A separate matter: AdBlue in a diesel tank around Upper Craigie
If what was put in was AdBlue rather than petrol, the opening step is the same — don't fire it up — yet the issue isn't. Petrol weakens your diesel and takes away the protection the fuel system depends on. Urea in water, AdBlue, and in a diesel tank that brings corrosion and deposits.
Often the more significant of the two, AdBlue — and the details lives on its own Upper Craigie page. Both are ours to deal with.
What a petrol-in-diesel fuel drain costs in Upper Craigie
What moves the price is listed below, because the job isn't one job and our technicians can't frankly put a single price on this page.
- Has it been started or driven? Nothing else counts for as much.
- How much of the wrong fuel went in, against how much that tank takes.
- Whether it is unleaded or AdBlue.
- Access: the car's position, and whether working on it there's sensible for our van.
Tell us the vehicle, the amount and whether it has run, and you will get a clear answer instead of a range. If it's not time-critical — the vehicle is at home and going nowhere — works too.
Petrol in diesel: frequent queries in Upper Craigie
I am on a forecourt in Upper Craigie. Can you drain it on the spot?
Plenty of what our technicians do takes place nowhere else. So yes. Routinely, provided the site consents: Morrisons, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that spot is something our engineers answer on the spot.
How much petrol is too much for a diesel?
Litres are not the measure. Proportion is, and a lot more than either, it counts whether anything has been 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 blend been drawn right through, or has it not?
I put petrol in my diesel and drove it. What next?
Turn off somewhere safe, and keep it that way after you stop. Driving is what shifts the trouble from the tank into the pump and injectors — but it's recoverable far more regularly than drivers assume, and the single most valuable thing you can do now isn't restart it.
My warranty — does a fuel drain void it?
It isn't a change, so a drain and flush carried out correctly does not cancel a manufacturer's warranty. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Could I put some two-stroke in and just drive?
No. Two-stroke oil is an old workaround for a different issue and it doesn't replace what petrol has thinned. The pump still has to cope with it, since that tank still has petrol in it later.
Do I need a main dealer for petrol in a diesel?
Not at all. Our technicians drain and flush your car wherever it is, so there is no need to take it to a franchised dealer.
Waiting next to it?
Shut off is how it stays.
If you have already driven it, pull in somewhere sensible, switch it off then keep it off. Cold and still, a vehicle is in the best place available — and motorists fear this a lot more than the recovery rate warrants.
Throughout Perth and Kinross and in Upper Craigie: on-site fuel draining, at home or on the forecourt or at the roadside.
