Is petrol in diesel worse than diesel in petrol?
Yes, considerably. Petrol strips the lubrication a diesel high-pressure pump depends on; diesel in a petrol engine mostly just refuses to burn. Call 01293 248666.
Local, mobile, and not a garage
There is no Wrong Fuel Newcastle premises, and we would rather say so than let a local name imply a local building. A technician covering NE1 to NE7, NE12, NE13 and NE15 travels to the vehicle — forecourt, driveway, car park or verge. Call 01293 248666 and you reach the people who dispatch to Newcastle upon Tyne, not a national queue.
Is petrol in diesel worse than diesel in petrol? The longer answer
Diesel lubricates the high-pressure pump as it passes through. Petrol is a solvent and removes that film, so a diesel pump run on petrol can wear rapidly and shed metal particles downstream into the injectors. Diesel in a petrol engine is messier than it is destructive — heavy smoke, misfiring, stalling — because diesel will not ignite properly from a spark. Both need draining. Only one of them gets dramatically worse with every mile.

What the wrong fuel does on its way through
Diesel lubricates as it passes; petrol dissolves that film and acts as a solvent. Run a diesel high-pressure pump on petrol and it wears fast, shedding fine metal into the injectors behind it. None of that happens while the fuel sits in the tank. All of it starts the moment the engine turns over.
A vehicle that stops on the Western Bypass, the Central Motorway or approaching the Tyne Tunnel is an operational problem before it is a fuel problem, and getting clear comes before everything else.
What to do now
- Key out, hands off An engine that has never run on the wrong fuel is a drain and nothing more. That is the cheapest outcome available and it is still on the table right now.
- Do not move the vehicle Not into a bay, not onto the verge, not around the corner — unless it is genuinely unsafe where it is.
- Hazards on, tell someone Forecourt staff are used to this and are rarely difficult about it once they know how long you will be.
- Call 01293 248666 and be specific Vehicle, wrong fuel, rough quantity, engine started yes or no. Those four things determine the price, and you hear it before we travel.
- Drain, flush, refill, prime Carried out where the vehicle stands, anywhere across NE1 to NE7, NE12, NE13 and NE15.
- Back on the road About an hour for a standard job. The waste fuel is removed under a transfer note that discharges your duty of care.

What people actually said
4.8 out of 5 from 2,190 Trustpilot reviews. Two themes dominate the positive ones — how fast someone arrived, and how calm they were about it.
The recurring negative is price. Publishing that alongside the answer seems more useful than hiding it: From just £89 misfuel callout fee is the call-out, the total is quoted before a technician moves, and there is no charge for being told on the phone that this is a job for a workshop.
