Petrol in a Diesel Car in Owens Bank: How Worried Should You Be?
Less than you likely are, provided it hasn't been started. Petrol resting in a diesel tank does nothing to the engine till something pulls it through the system — the ignition priming the pump, the starter, or driving on its own. So the truthful answer to the first question everyone around Owens Bank asks, "have I ruined it?", is normally no. Petrol in Diesel is who to call, with your engine left off, so it stays that way. Read on for three things: the effect petrol has inside a diesel motor, the signs of how far it has spread, and the way to make sure you don't repeat it.
The motor and petrol in a diesel: what happens
On its way through a motor, diesel has two jobs. It ignites, and before it ignites it lubricates. Very fine clearances go into your injectors and your high-pressure pump, and just the diesel running through keeps their surfaces from grinding together.
Poorly at the first, not at all at the second: that's petrol. Being less viscous than diesel, petrol strips out the protection a fuel system needs, leaving a pump on the mixture to wear itself. It is also made to resist igniting under compression — the reverse of what a diesel needs — which is why you hear the rattling.
Put those together and the shape of the problem is plain. It is circulation that causes the damage, not contact. A tank with petrol in it is a fuel problem. The start of a mechanical problem is a pump that has been labouring on that petrol — and whatever a worn pump sheds travels on with the fuel to the fuel injectors beyond it.
Petrol in a diesel around Owens Bank: how serious is it? Four cases
Filled up, not once started. The best case there is. On a forecourt, and truly only there, the petrol is still confined to the tank — since anywhere else the car was driven to reach it. The job is draining and cleaning on the spot.
Ignition on, or started for a moment. Petrol has come out of your tank and got to the fuel filter and the fuel lines, since the system has been primed. That's normally still a simple job — a drain, a flush, and the fuel filter dealt with.
Those few miles on the road were your pump working on fuel weakened by petrol throughout. The work is that tank, your lines, the filter and fresh fuel through the whole system, and how hard your car was driven matters as much as how far. On the school run to Richard Wakefield CofE Primary Academy, the miles is short. Getting as far as Derby, under 15 miles away, makes a very different job — as does any mileage on the M42, under 15 miles from Owens Bank, with the engine working hard all the way.
Clattering, a lumpy idle, smoke, a throttle gone soft: driven till it complained. The motor is telling you your fuel is no longer behaving like diesel. Leave it where it stops: a lay-by, a side street, the verge on Redhill Lane. Long-term damage is very rare if a car is pulled over early, and the fuel drain and flush that still come first take care of it.
Owens Bank motorists and the petrol in a diesel myths they hear
Myth: topping up to full with diesel makes it fine. It doesn't. Topping up removes nothing; it gives you a fuller tank of the same mixture. Percentage is not how a diesel fuel system tolerates petrol, whatever that advice assumes.
Myth: "A modern diesel can cope with a bit of petrol." If anything, the opposite. A current diesel runs its fuel through finer parts at higher pressure, which makes the protection matter more, not less.
"It starts, it drives, so there is no harm" — the myth that catches more drivers than any other. The motorist of a petrol engine fed diesel usually has no choice but to stop, because it will not run, and the damage stops with them. Nothing seems to have happened when a diesel fed petrol fires up, ticks over and drives away, which it usually does; meanwhile your pump wears. Running isn't the same as fine.
Myth: "Add some two-stroke oil and drive the vehicle home." It's an old fix for a separate problem. None of what petrol thinned gets put back by it — and afterwards, your tank still holds that petrol.
Myth: "Drain your tank yourself and you're sorted." After the motor has run, some of the petrol is no longer inside the tank: it is in the fuel filter and the lines, and it goes straight back through the pump on your next start. On top of that, petrol cleared into a can by the road is truly hazardous.
How petrol ends up: petrol in a diesel
A careless moment is rarely the cause, and nobody means to do it. One way only, because of the nozzles: the smaller petrol one slips inside a diesel filler with almost no resistance, while the diesel one mostly won't fit a petrol car. That's how the forecourt makes it simple.
The moment habit stops matching the car is the moment it occurs. A new vehicle, a hire car or a courtesy car. Two vehicles on one drive, one petrol, one diesel. The pumps in a different order on a familiar forecourt. A train to catch, and a rushed fill on the way to Tutbury & Hatton. Years of petrol motors behind you, a diesel Renault Megane in front of you on the forecourt for its first tank — that's when. Add rain, a phone call or a back seat full of kids, and the hand repeats what it has always done.
Next time you fill up around Owens Bank: avoiding petrol in a diesel
- The label is what matters, and so read the pump instead of the colour: in the UK unleaded handles are usually green and diesel black, yet not on each forecourt.
- In a motor you do not know, look inside the flap over the filler or at the cap before your first fill: plenty of vehicles state the fuel type there.
- Good intentions count for less than a sticker or a fob in a bright colour on your diesel's key when a house has one of each. So mark it.
- Say it before you lift it. On the first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the petrol pump. It sounds silly and it does the trick.
- Thinking about something else is when this becomes an easy mistake to make, and so put the phone away and keep your mind on the pump.
- Up to a point, a misfuel inhibitor helps: some diesels have a filler built to reject a petrol nozzle, and aftermarket devices exist for the rest. Count it as a safety net, then keep checking the petrol pump.
- Spotting it halfway? Stop at once. A weaker mix follows from less petrol in the tank, but your next stage remains the same: don't fire it up.
Put petrol in a diesel around Owens Bank already?
Then the order of things is brief. Starting it is out, and so is turning on the ignition. Yet at the forecourt, at Essar or anywhere else? Ask the attendants to help you push the vehicle clear of the pump. Then phone 0333 366 0103 and tell us what was put in, about how much, and if it's run.
Say so if it was AdBlue rather than petrol: it's a different issue, with its own page for Owens Bank, because AdBlue brings corrosion and deposits rather than lost protection.
Why one petrol in a diesel job around Owens Bank costs more than another
An honest single quote does not exist here: four situations, four separate tasks. What moves your cost is chiefly which of them you are in. The share matters next, meaning how much of the tank is petrol, and then the location of the car and whether reaching it is safe for a van.
Before any quote, not after, we ask three queries: your fuel that was put in, its volume, and whether it's run. That's why. Given those answers, you get a straight figure instead of a range.
