One number, 01293 248666, answered by someone who knows which roads round Sunderland are slow at this hour. **Where**: Roker, SR6 **Nearest to us**: North Haven, St Peter's Riverside and South Bents **Roads**: A183 **What it costs**: Call-out £89 to £199, drain £199 to £1,999, full price before we travel **Time on site**: About an hour **Phone**: 01293 248666 ## Why misfuelling happens in Roker Roker sits across the SR6 postcode district and the A183, with North Haven, St Peter's Riverside, South Bents and Seaburn next door. Most calls from this area come from supermarket forecourts at the end of the working day, when the pumps are busy and the driver is thinking about something else. Wearside calls lean heavily industrial: plant and supply-chain traffic filling at the same A19 forecourts at shift change, plus a large Washington van and fleet population on the Sunderland Highway. The mechanical reason petrol-in-diesel dominates is nozzle geometry: an unleaded nozzle drops straight into a diesel filler neck, while a diesel nozzle is usually too wide for a petrol one. It is hardware, not carelessness. When it happens: Shift change on the A19, and a separate residential pattern on Durham Road and Chester Road that skews towards the first tank after someone changes car. ## Where the damage actually occurs Not in the tank. The tank is just where it starts. Damage happens at the high-pressure pump, which relies on the fuel itself for lubrication and has very tight tolerances, and then at the injectors downstream of it. Reaching either requires the engine to have run, which is why a car coasted to a halt on the forecourt is almost always a call-out and nothing more. ## What happens, in order The single rule Leave the engine off. Everything else on this list is secondary to that one instruction. - Do not reposition the car Pushing it into a bay feels considerate but it disturbs the fuel. Stay put unless you are in danger. - If it is dangerous, get out On a verge or live road, everybody out on the side away from traffic and behind the barrier. Then call. - Call 01293 248666, day or night Answered around the clock. Describe the vehicle and what happened; the full price is confirmed on that call. - The fix, where you stand Drain, flush, refill, prime and run-up, carried out at the roadside or on the forecourt. - Finished properly The waste is taken away by a registered carrier with the transfer note, and you get an invoice. ## Unleaded in diesel near Roker - North Haven - St Peter's Riverside - South Bents - Seaburn - Whitburn - Fulwell ## Other services in Roker - Petrol in diesel in Roker - Diesel in petrol in Roker - Fuel doctor in Roker - AdBlue in diesel in Roker - Small amount of petrol in Roker - Misfuel in Roker - Fuel drain in Roker - Mobile fuel drain in Roker - Wrong fuel rescue in Roker - 24 hour fuel drain in Roker ## More about Roker - Roker coverage - All of Sunderland ## What drivers tell other drivers 4.8 stars, 2,190 Trustpilot reviews. The advice drivers pass on is simple: do not start the engine, ring, and expect someone level-headed who knows exactly what to do. The warning they pass on is that it is not cheap. Fair enough — the call-out runs £89 to £199, the drain £199 to £1,999, and both are stated before a van leaves, so nobody is surprised at the roadside. ## Questions we get asked **Do I need to stay with the vehicle?** Usually yes, so we can hand it back to you running. If you cannot stay, say so on the call and we will work out how to do it. **What happens to the old fuel?** It leaves with us as controlled waste under a waste transfer note. It is not tipped, and it is not resold to you. **Do you work at night?** Yes, around the clock, every day. A large share of misfuels happen after dark, so the rota reflects that. **Is there an out-of-hours surcharge?** The call-out is the call-out. Whatever the total is, you hear it on the phone before anyone travels. ## Who you are dealing with Wrong Fuel Sunderland is a service by Forecourt Assistance.
