Mobile fuel drain in Portsmouth
We cover every postcode district in Portsmouth — PO1, PO2, PO3, PO4, PO5, PO6 — and the surrounding Hampshire villages, home to around 208,000 people. Wherever you are when you realise, our technicians bring the drain to you: the supermarket forecourt, the retail park, your street or your workplace car park.
Portsmouth is right by the M27 (Southampton to Portsmouth) and the M3 about 16 miles away. Motorway fuel stops are where most misfuels happen — tired drivers, unfamiliar cars, pumps in a different order from your usual station.
Nearby service areas we regularly attend: Rownhams (M27 J3–4, 18 miles); Winchester (M3 J8–9, 22 miles); Fleet (M3 J4a–5, 34 miles). If you've misfuelled there, stay on the forecourt or move into the car park — don't drive.
Our Portsmouth technicians also cover Cosham, Southsea, Gosport, Fareham, Waterlooville and the roads between.
Petrol in diesel in Portsmouth
The most common misfuel we see in Portsmouth. Petrol strips the lubrication a diesel's high-pressure pump relies on, so the golden rule is simple: leave the engine off. Our technician drains the tank, flushes the system, adds 10 litres of fresh diesel and tests the car before leaving. More about petrol in diesel.
Diesel in petrol in Portsmouth
Rarer, because the diesel nozzle is wider, but it happens — especially with vans and older cars. Diesel won't burn in a petrol engine and will foul the plugs. Same fix: engine off, call us, drained and refuelled at the roadside. More about diesel in petrol.
