Diesel in a petrol car in Teesside: what to do
Put diesel in a petrol car? It is less destructive than the reverse — diesel will not ignite properly from a spark — but it still has to be drained out. Call 01293 248666.
Why it happens less often
A diesel nozzle is usually too wide to fit a petrol filler neck, so this mistake is partly designed out at the pump. It still happens — with older cars, with jerry cans, and at forecourts where the nozzles are not the standard sizes.
What diesel does in a petrol engine
Very little that is catastrophic. Diesel will not ignite reliably from a spark plug, so the engine smokes heavily, misfires, and eventually stalls. It fouls the plugs and can clog the filter, but it does not strip lubrication the way petrol does in a diesel.
Still drain it
It still has to come out, and the plugs and filter are worth checking afterwards. Around Teesside it is the same call, the same price and the same hour on site as any other misfuel.
Around Teesside
Teesside calls are more commercial than almost anywhere else in the network: process-plant fleets, port and freight traffic, and contractor vans. Drivers in a works vehicle they do not normally take out are the single most over-represented group in misfuel work. Shift patterns rather than rush hours, plus a summer coastal peak towards Redcar and Saltburn on the A174.
That applies across the villages we cover, including Kirklevington, Hilton, Maltby, Thornton, Seamer, Newby, Kildale, Hutton Rudby, New Marske, Dormanstown, Coatham and Kirkleatham.
- Leave the key alone This is the one that decides the price. Wrong fuel sitting in a tank is a drain; wrong fuel that has been through the engine is a different job.
- Do not push or coast it Moving the vehicle can slosh contaminated fuel toward the pickup. Leave it where it is unless staying there is unsafe.
- Make yourself safe Hazards on. On a forecourt, tell the cashier — they will almost always let you stay put once they know a drainer is coming.
- Call 01293 248666 Tell us the vehicle, which fuel went in, roughly how much, and whether the engine ran. You get a full price before anyone sets off.
- We drain, flush and prime Tank emptied, lines flushed, fresh fuel in, system bled and run up before we go.
- You drive away Most jobs finish on site in about an hour. The old fuel leaves with us under a waste transfer note.
Why the engine matters more than the litres
People assume a splash is fine and a full tank is a disaster. It is the other way round. Wrong fuel sitting in a tank is inert — it is a drain. Turn the key and it travels: lift pump, filter, high-pressure pump, injectors, and every stage it reaches adds a component to the bill. Five litres burned is worse than fifty litres left alone.
Downtime on a commercial vehicle costs more per hour than the job itself, which is why draining on site rather than recovering to a workshop is usually the only answer that makes commercial sense here.
The cost, honestly
There is one fixed figure and one variable. The fixed figure is the call-out; the variable is whether the engine ran, and for how long.
| Call-out | From just £89 misfuel callout fee |
|---|---|
| Engine never started | Usually the drain and flush only |
| Engine run briefly | Drain, flush, often a new fuel filter |
| Driven some distance | May need the high-pressure pump or injectors checking — a workshop job |
| When you hear the price | On the phone, before anyone travels |
Questions we get asked
Can you come to a supermarket forecourt?
Yes, and it is where a good proportion of jobs happen. Tell the cashier a drainer is on the way; they are used to it.
Do you cover all of the TS postcode area?
Yes, from one rota — so being at one edge of the area rather than the other changes the arrival window, not the price.
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.
What about a van or a hire car?
Same job. With a hire car, ring the hire company too — some policies cover a misfuel drain and it is worth knowing before you pay.
What if it is not safe to drain where I am?
Then we tell you that on the phone rather than after arriving. Being told honestly costs nothing; being told on arrival costs a call-out.
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.
