Petrol in Diesel

Tuckhill: Put Petrol in a Diesel Car?

If you have not turned on your engine yet, do not. A drain and nothing more is nearly always what a vehicle requires while the petrol is still inside that tank and the motor has not been started, which is why it's the next few minutes that count, not how much went in. Petrol in Diesel goes to the vehicle wherever it has ended up in Tuckhill or the rest of Shropshire, on the forecourt, at the roadside or on a private drive, and drains and cleans it there. One ring to us will be plenty: we shall explain what comes next. Do that straight away.

Your first five steps: petrol in a diesel

  • While you drive, your pump and the fuel injectors suffer. That is why you do not fire it up, and why you never rely on it once it has started. The catch about petrol in a diesel specifically — the bit motorists get wrong — is that it pulls away fine for the first mile or two. Diesel in a petrol engine usually cannot run at all, which stops the person and stops the wear with them. This one lets you drive on.
  • Two jobs, diesel: it burns, and on the way through it keeps your high-pressure pump and injectors oiled. Petrol only does the one. That is why the car's ignition stays off too — switch it on and you usually prime the system, and that is petrol leaving the tank for precisely those parts.
  • Don't thin it. Diesel added on top takes out nothing, and so all you have is more of what was already there, since percentage is not how a diesel fuel system copes with petrol. Super unleaded? Simply petrol. The octane makes no difference.
  • A motor that hasn't shifted is the quickest one to sort out, so remain where you are if you reasonably can. Parked on the verge on A458? Hazards on, and keep the car there. A tricky location works for us better than a started motor.
  • A van showing up instead of circling turns on two things: a postcode starting WV15 6, and whatever is next to you with a sign on it. Have both ready before you phone.
  • Three answers settle your whole visit: the stuff you tipped in, the rough quantity involved, plus if anything has been going since. The number is 0333 366 0103.

Do not take it home. Petrol-thinned diesel has run through that high-pressure fuel pump in real volume on the road in, and the drive back would about double that for nothing at all. Call us — the platform is fine. There is no need to stand over that Volkswagen Golf outside Stourbridge Town while the work gets done, and we'd far rather hear from you tonight than find out on Monday.

Diesel Renault Megane. A few litres of unleaded. Run a couple of miles. Switched off now, outside ALDI. That's the call our engineers want, since the point underneath it's about volume through the pump instead of hours on the clock.

You will be told to shift the vehicle clear of that gateway and fix it later. Do not. On the zig-zags by Alveley Primary School, a misfilled Nissan Qashqai running on diesel is in the way, and that's all it is. Fire it up three more times being polite and you have turned a tank into a fuel system: every start primes the fuel lines, every prime drags more petrol through the fuel filter toward your pump. Let them complain. Phone us.

Risk the journey home from the pub in the village? No. It will fire up and it will pull away just fine, which is the problem — a diesel on a thinned tank acts usually while wearing down the parts the fuel should be protecting. Leave the Audi A4 then call us.

Somebody certain will tell you to drain the vehicle then put new diesel in. Only half right, that. Try it on a diesel Seat Leon near St Andrew's and the motor will start — which is exactly why it sounds like sense. Here's the problem: there's petrol left in the filter and the feed lines, and the first thing the engine does is draw it back through the pump once more. Draining a tank achieves nothing about fuel that already left that tank. Ring us. The system gets purged, the filter comes off where there is one worth removing, and that is what separates a fixed vehicle from one that only starts.

At the forecourt: clearing petrol from a diesel

The work starts at the pump, mostly. Quite often the work finishes there as well. The drain normally takes place right there. Still on the forecourt at the nearest petrol station? Given the owner's agreement, that is a spot we work, and regularly.

At the forecourt, this gets spotted with the motor never fired, and no place else manages that. Fuel pulled out of the tank and through the filter, right to the high-pressure fuel pump, is what happens when the motor is started and the car is moved to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush covers your filter and your lines as well as that tank. That's still not a disaster, and we deal with it where the vehicle stands. What decides it is whether the key was reached for in the seconds after the receipt was read.

Out from the pump, the next driver can get past — so yes, let the attendants help you roll the vehicle. Well worth doing. Four car lengths is not worth the risk.

Service in Tuckhill

As a rural hamlet, Tuckhill sees a routine visit, and the places close by come with it on the same trip: Six Ashes and Kingsnordley, Broad Lanes and Broad Oak, Four Ashes.

There are pages for the majority of towns around Shropshire, and the ones mentioned above are just the immediate neighbours — so yours being left off this list says nothing whatsoever about if we come. Ring us to check instead of guessing — borders particularly, and wherever your satnav may get wrong.

The map outlines the area this page spans. Kerbside, forecourt, private drive, car park: all of it is territory we cover, and none of it asks your car to travel to us.

Roadside breakdowns around Tuckhill

Some drivers have no safe spot to stop at all. Set off, then realised? Landed by the verge beside Batfield Lane, or parked in some lay-by with the hazard lights going? That's a common call here. Not an odd one.

Whether you stay by the vehicle or keep away from it depends on whether being there feels sensible. It will usually oblige. A diesel running on petrol limps along quite willingly, and that's the trouble: fire it up to reach somewhere safer and the mix goes further into the system with every mile driven. However difficult the location, it is no problem for us to get to it, and that's a lot better for the car than pressing on.

Some miles on petrol in a diesel: what now?

under 15 miles out of Tuckhill, the local M54 is what matters here. It will usually take you onto it, and some way along, before you notice a thing. Then it is smoke, a lumpy idle and power draining away — not a neat stop. Misfilled diesels seldom give you one of those.

The next safe exit is the one to take. Turn off there, then leave the restarting alone. Assume the worst of that on a long run. Anything close to the under 15 miles to the closest city, and the contamination has been through the filter, through the pump, through the fuel injectors. Tell us when you ring. What our technicians bring changes.

Where is Tuckhill?

Tuckhill is a small hamlet in Shropshire, situated inland at an elevation of 146 metres, and is located near the villages of Six Ashes and Kingsnordley. Tuckhill has a population of around 579 people, and its housing stock is predominantly made up of detached homes. Tuckhill is close to the city of Wolverhampton, which is approximately 10 miles away, and is about 115 miles northwest of London.

What comes next when we get to you in Tuckhill

  • Three things get established before any price — your fuel that was put in, the amount, and whether anything has been run since. Each answer shapes the work.
  • Our engineers clear your tank of all the tainted mixture.
  • Our engineers purge the fuel lines and clean the filter, so what's left in the system is not what created the problem.
  • New diesel goes in, and then your system gets primed.
  • Our technicians fire it up and check it runs correctly on fresh diesel.

From there, you are ready to pull away. All of this is done where your car is, so it never needs to go to a workshop, and when it has been caught soon, long-term damage is very uncommon.

AdBlue in the diesel tank by mistake, in Tuckhill?

AdBlue instead of petrol? Then the opening rule is unchanged — your engine stays off — whereas this problem underneath it's a different one altogether. Weakened diesel, and no protection left for the system that depends on it. That is petrol. Rust and build-up are what a diesel tank ends up with instead, because AdBlue is urea in water.

Both are ours. There is a separate Tuckhill page for AdBlue removal, with the detail on it — including the reasons it frequently turns out to be the worse of the two.

Paying for a petrol-in-diesel drain around Tuckhill

Honestly, no single number fits on a page like this. The job differs. Here is what varies it:

  • Whether the engine has been run or driven. This is the big one.
  • How much of the wrong fuel got in, compared with how much that tank can hold.
  • Which went in: petrol or AdBlue.
  • Access: the car's position, and whether working on it there is sensible for a van.

The car, the amount, whether it has run — give us those and the answer comes back clear rather than as a range. For the vehicle at home that's going nowhere and isn't urgent, works too.

Questions our engineers hear about petrol in diesel in Tuckhill

Fuel drains on a Tuckhill petrol station forecourt

Yes — forecourts are where a fair portion of this gets done. Regularly, provided the site consents: Shell, 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 straight away.

How much petrol is too much for a diesel?

Litres aren't the yardstick. Proportion is, and a lot more than either, it matters whether anything has been run. What decides how much work is required is if that mix has been sucked through the system — because although five litres in an almost empty tank is a distinct case from five in a full one, either way that's the query.

I put petrol in my diesel and drove it. What next?

Stop sensibly. Off. Nothing after that. Driving moves the problem along — out of the tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you isn't restarting the vehicle.

Fuel drains and manufacturer warranties

No. Carried out properly, emptying and cleaning is no modification at all, and the warranty from your manufacturer is unaffected by it. Another good reason to leave it switched off: running a diesel on petrol is the thing more likely to cause an argument with one.

Two-stroke oil in the tank, and then home?

No. It belongs to a different issue from a bygone era, and petrol has thinned something no oil of that kind replaces. Your pump still has to put up with it, because the tank still has petrol in it afterwards.

A main dealer for petrol in a diesel — needed?

There is no need to take it to a franchised dealer, as our technicians drain and clean your car wherever it is.

Still with the car?

The engine remains off.

Switch it off somewhere safe then keep it off, if you have already driven it. Cold, parked, going nowhere: that's the best position to be in. People fear this much more than they need to.

Emptying misfilled cars, Tuckhill and the rest of Shropshire, wherever they are. Kerbside. Forecourt. Home.
