Putting diesel in a petrol car in Edinburgh is a mistake, but honestly, it’s the less serious one. Serious damage rarely happens if you handle things the right way, so try not to panic.
Don’t start the engine, and don’t even turn the key to check anything. That can pull diesel further into the system, which you definitely don’t want.
Still, you can’t just ignore it. The tank needs to be drained before you drive anywhere, even if it’s just a short hop.
The upside? Our mobile technician can come to you anywhere in Edinburgh. No need to mess around with a tow truck.

Why diesel in a petrol car is the less serious mistake
(For Illustrative Purposes Only)
If you mix up fuels at a forecourt in Edinburgh, the direction of the mistake matters. Petrol in a diesel car is a bigger headache than diesel in a petrol car, and there’s a good reason for that.
Diesel does more than just power a diesel engine; it lubricates the high-pressure fuel pump. Petrol strips away that lubrication, and that leads to wear spreading through the fuel system.
Petrol cars don’t need lubrication from the fuel in the same way. Diesel doesn’t ignite easily in a petrol engine; it’s thicker and heavier. Instead of wearing things out, it clogs the fuel system and fouls the spark plugs.
Less serious doesn’t mean harmless, though. Diesel in the tank will still stop your car from running right or from starting at all.
A tiny splash mixed with lots of petrol isn’t the same as a tank full of diesel. Either way, don’t just guess; book a recovery service and get it drained properly.
Symptoms of diesel in a petrol car
(For Illustrative Purposes Only)
If you haven’t started your engine, you won’t notice any symptoms. The diesel just sits in the tank and hasn’t moved through the fuel lines. Don’t start your car to check if it runs; this is when damage can really start.
If you have started the engine or driven off, you’ll probably spot some clear signs:
- Difficulty starting the car
- Rough idling and rough running
- Heavy misfiring
- Clouds of white or grey exhaust smoke
- A strong smell of diesel
- Spluttering and loss of power
- The engine cutting out or refusing to run
The smoke is usually the most obvious clue. Unburnt diesel burns differently than petrol in a petrol engine, so you’ll see heavier, more noticeable exhaust smoke.
These symptoms tend to show up quickly once you start the car. That’s why leaving it switched off is your best move. Not sure which fuel you used? Check your receipt or the label inside your fuel flap.
If it happens in Edinburgh: the Bypass, the Old Town and city forecourts
(For Illustrative Purposes Only)
If you’re on the City Bypass (A720) and you notice rough running or idling, put safety first. This road is fast, so if your car’s still moving, get to a safe spot off the carriageway before switching off.
Get out on the side away from traffic and stand well back, behind a barrier if possible. If you can’t clear a live lane or feel unsafe, call 999 right away.
In the Old Town and city centre, streets are narrow and often cobbled, with tight parking and bus lane rules. If you’ve put diesel in a petrol car here, pull over somewhere safe and legal, switch off, and call 0131 235 2742.
Give your exact location, including the street name and a nearby landmark, so help can find you. Central restrictions might limit where a recovery vehicle can stop.
If you catch the mistake at a forecourt, switch it off right away and let staff know. Don’t try to top up with petrol to dilute the diesel; that just increases the amount of contaminated fuel that needs draining.

Frequently Asked Questions
What should I do immediately if I have put diesel into a petrol car?
Turn the engine off right away and don’t start it again. Don’t even turn the key. Call our mobile drain service to come to you. The car’s safe as long as it stays switched off.
Can I drive my petrol car after accidentally filling it with diesel?
No, don’t drive. It might run rough, stall, or not start at all. Driving just pushes diesel further through the system, so get the tank drained first.
Will putting diesel in a petrol car cause permanent engine damage?
Usually not, as long as you never started the engine. The main risk comes if diesel gets pulled through a running engine, so leave the key alone.
Can a roadside recovery service drain a misfuelled petrol car in Edinburgh?
Yes, our mobile technician can come out anywhere in the city. They’ll drain and flush the system, then refuel it on-site, so you don’t need a tow. Call 0131 235 2742 for help.
Does my car insurance cover the cost of diesel misfuelling recovery?
Your policy might cover misfuelling, but not all do. Take a look at your documents to be sure.
Hang onto your receipt and the job record. These could help if you decide to make a claim.
