Petrol in a Diesel Car in Stoneyholme
With that tank still holding the fuel and the engine not yet run, nearly every job requires only a drain, so leave the motor off. That result is decided in the minutes immediately after the fill-up, rather than by the amount that went in. Throughout Stoneyholme and the remainder of Lancashire, Petrol in Diesel drains the car and cleans it where it sits, whether at a roadside, on a driveway or at a forecourt. Call us before anything else starts, so you'll learn what follows after that.
What to try first about petrol in a diesel
- Give a petrol motor diesel and it will typically refuse to run at all, and so the motorist stops there and so does the damage. Give a diesel petrol and the thing starts, it ticks over, it pulls away — fine for a few miles. Most people have that reversed, which is the thing they get wrong about petrol in a diesel specifically. So never crank it. And having started, do not depend on it: your fuel system is grinding as you drive.
- Switching the car's ignition on usually primes that system, and priming is what pulls petrol out of your tank then into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it ignites. Petrol manages the burning and none of the lubricating. Leave your ignition be.
- Topping up clears nothing. It gives you a bigger tank of the same mixture, because a diesel fuel system does not handle petrol by percentage as that advice implies — so do not pour diesel on top to weaken it. Grade is beside the point too: super unleaded is petrol.
- Wait where you are if you sensibly can. A vehicle that has not moved is the easiest one to sort out, and we would much rather come to a difficult location than have it started. If you're pulled up on the verge on Kent Street, switch the hazards on then keep the vehicle there.
- Our van arriving rather than circling turns on two things: a postcode that starts BB12 0, and whatever is next to you with a name on it. Get both ready before you phone.
- Dial 0333 366 0103. Prepare for three points — what was put in, approximately how many litres, and if the car has been run. Those replies determine everything that comes after.
Don't drive it home. The drive in has already sent a real amount of petrol-thinned diesel through the high-pressure fuel pump of that Volkswagen Passat, and the trip back would about double it for no gain at all. Phone us from the platform if that's handier. We never need you standing over your car at Burnley Central whilst our technicians get on, and we'd very much rather hear from you tonight than realise on Monday.
If you have put petrol in the diesel BMW 3 Series in Stoneyholme and you are now stranded outside Asda with a boot packed with shopping, phone us. Do not start it again to leave that space. Our technicians will come out to you, empty the tank, flush your fuel lines and put fresh diesel in so you can drive away. A mile or so at light throttle pulls very little fuel, which is why those are often the straightforward cases.
Your diesel Mercedes C-Class will have felt perfectly ordinary on the way back from Burnley Stoneyholme Community Primary School. They do, and that's the catch with petrol in a diesel and not the other way round. Put diesel in a petrol motor and it usually won't run, and so the driver stops and the wear stops with them. Put petrol in a diesel and it starts, idles and drives off as though nothing has happened — meanwhile the high-pressure fuel pump works without the lubrication your fuel is meant to be providing. Nothing tells you, since from the driver's seat there is nothing to alert you about. Call us with roughly how far you travelled and how hard you worked it; the second one matters more than the first.
Nothing gets worse while it sits. Whatever the diesel Vauxhall Astra did on the way to Thursby Gardens, it's doing none of that now: the pump is not turning. So take your time — but don't drive the car home to buy yourself any.
A person confident will tell you to drain the car and put new diesel in. Half right, that. Try it on a diesel Peugeot 2008 by Marks & Spencer and the motor will start — which is precisely why it sounds like sense. Here's the problem: there is petrol left in the filter and the feed lines, and the first thing the motor does is suck it back through the pump again. Emptying a tank achieves nothing about fuel that already left the tank. Call us. Your system gets purged, the fuel filter comes off where there's one worth removing, and that is what separates a repaired motor from one that merely starts.
At the forecourt: draining petrol from a diesel
A large portion of the work is completed at a forecourt, since that's where it usually starts. We work on station forecourts regularly, with the site's consent, so if you're still at Asda that is normally where the drain takes place.
No place except a garage can this be spotted with the motor still unrun. Fuel pulled out of your tank and through your filter, right to your high-pressure pump, is what occurs when the engine is fired up and your car is moved to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush includes the filter and the fuel lines together with the tank. That is still not a disaster, and our engineers deal with it where your car sits. What determines it is whether the key was turned in the seconds after your receipt was checked.
Clear of the pump, the next driver can get past — so yes, let the staff help you push it. Well worth doing. Cranking the car for four car lengths? Never.
Parts our team reach in Stoneyholme
As a residential suburb, Stoneyholme sees a routine call, while its neighbours close by come with it on the same round: Whittlefield and Burnley, Burnley Lane and Fulledge, Heasandford.
Not on the list? That means nothing. The places above are only the nearest few, and the majority of places around Lancashire have a page of their own somewhere on this site. Close to the boundary, or anywhere a satnav misreads? Ring us to check instead of presuming.
This map shows the patch this page includes. We work at the roadside, on forecourts, on driveways and at car parks throughout all of it, and your car doesn't need to move to us.
Stoneyholme: stranded wherever you parked
Not everybody has a safe spot to pull in. Hazards on at a lay-by somewhere, or pulled onto the verge beside Brougham Street since you worked it out after setting off — our engineers take that call often enough that it's the normal kind.
Safe there? Remain with it. Not okay? Climb out and clear of it. Don't restart your motor to limp the car somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is pulling that mix further into your fuel system. A technician coming to an awkward spot is no problem for us, and it is a lot better for the vehicle than carrying on.
Run it already? Pull in, and check below
under a mile out of Stoneyholme, your M65 is what matters here. Some distance along, and onto it in the first place: a misfilled diesel will usually do both before anything seems wrong. What you get then is rarely a neat stop. Power ebbs away, the idle gets uneven, and there may be some smoke.
Get off at the next sensible exit, switch off, and do not restart it to reposition. Presume the worst of that on a long run. Anything near the under 25 miles to the nearest city, and the petrol has been through your filter, through the pump, through the fuel injectors. Say so when you call. What our engineers bring alters.
About Stoneyholme
Stoneyholme is a suburban area situated on the riverside in Lancashire, with a mix of terraced housing and local amenities. Stoneyholme sits at an elevation of 115 metres, approximately 18.5 miles from Preston and 181.4 miles from London. Stoneyholme is located near other local places such as Whittlefield and Burnley, and is characterized by its predominantly terraced housing stock.
Once our technicians reach you in Stoneyholme: what follows
- We ask first, price after. What went in? How much? Has the motor run? Those replies shape what the work really is.
- Away comes the polluted fuel.
- Lines rinsed, filter cleaned. Whatever remains later isn't the thing that created the issue.
- We put new diesel in and prime the system.
- It is started with new diesel in it, and we make sure that it is running properly.
Then it's ready to drive away. We do everything wherever the car has stopped, which means it never has to be taken to a workshop, and when it has been noticed quickly, it's very rare for there to be lasting damage.
Stoneyholme AdBlue removal is a separate matter
If what went in was AdBlue rather than petrol, the first rule is unchanged — never crank it — but the problem isn't. The protection a fuel system depends on is taken away by petrol, which dilutes the diesel. AdBlue? Urea dissolved in water. Tip that in with your diesel and you get rust instead, plus deposits.
We deal with both, and AdBlue removal around Stoneyholme has its own page with the full story — including why it's often the more serious of the two.
Stoneyholme pricing for a petrol-in-diesel drain
What changes the price is laid out below, as the job isn't one job and our technicians can't frankly put a single number on this page.
- Whether your engine has been run or driven. This is the key one.
- The tank's capacity, set against how much of the wrong fuel got into it.
- The sort of fluid in the tank, unleaded or AdBlue.
- Where is it? And can our van get to it and work there sensibly?
A straight answer instead of a range is what you get for telling us three things: your car, the quantity, and whether it has run. If it's not time-critical — the vehicle is at home and going nowhere — works too.
Petrol in diesel queries from Stoneyholme drivers
I'm on a forecourt around Stoneyholme. Can you drain the vehicle on the spot?
Yes, and it's where a large share of this work takes place. Tell us which one you're at when you ring and we will tell you whether we can work there. With the site's agreement our engineers work at Shell and the other forecourts locally all the time.
Is there a safe amount of petrol in a diesel?
Whether the motor has run counts far more, though the ratio counts too, rather than the litres. A nearly empty tank with five litres in it, against a full one with the same five: separate scenarios, certainly. Either way, the work needed comes down to one thing, which is if your fuel system has had that mix pulled through it.
I put petrol in my diesel and drove the vehicle. What next?
Turn off somewhere safe, and keep it that way after you stop. Not restarting it is the single most helpful thing available to you now. Driving does move the issue out of that tank then into your pump and injectors, yes, and it remains recoverable far more commonly than drivers expect.
Is a fuel drain going to void my warranty?
A drain then flush carried out properly isn't a modification and does not invalidate a manufacturer's warranty. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Two-stroke oil in the tank, and then home?
Two-stroke oil solves a different fault, and an old one at that. Nothing it does puts back what petrol weakened. No. Your pump still has to put up with it, because that tank still has petrol in it later on.
Main dealers and petrol in a diesel
Wherever your car is, our technicians drain and clean it there, so a trip to the main dealer does not come into it.
Standing next to it?
The motor stays off.
If you have already driven the vehicle, pull over somewhere safe, turn it off and keep it off. This is recoverable from much more often than motorists assume, and a stationary, cold car is the best place to be in.
