Put petrol in a diesel, or diesel in a petrol? Do not start the engine. That single decision is worth more than anything else on this page, and it is the difference between draining a tank and rebuilding a fuel system.
DK's Recovery covers Sheffield and South Yorkshire 24 hours a day. We move misfuelled vehicles to a garage that can drain and flush them properly, without the engine ever being run.
It is the most common expensive mistake on British forecourts, and the damage is almost always done in the thirty seconds after the mistake rather than during it.
The wrong fuel is sitting in the tank and nowhere else. That is a drain and a flush, and the car usually drives away afterwards. Leave the key alone, do not put it in the ignition at all on a car with keyless start, and do not push it off the forecourt with the ignition on.
Fuel has now been pulled through the lines. In a diesel the damage is worse than most people expect: diesel lubricates the high pressure pump, petrol strips that lubrication, and the pump can shed metal particles through the whole fuel system. That turns a straightforward drain into pump, injector, rail and filter replacement, and it is the reason we ask on the phone whether the engine has run.
Petrol in a diesel is the expensive one and by far the most common, because a petrol nozzle fits easily into a diesel filler neck. Diesel in a petrol car is less common, because the wider diesel nozzle does not fit most petrol fillers, and it is usually less destructive — but it still needs draining rather than diluting.
Topping up with the right fuel and hoping does not work and makes the drain harder. Neither does an additive. The tank needs emptying, and that is a workshop job with the right equipment, not something anybody should be doing at the kerb.
We collect the vehicle on a flatbed with the engine never run, and take it to your garage or one that does fuel drains. Our guide to what to do when you put the wrong fuel in goes through it in more detail.
Forecourts on busy roads, late at night, and anywhere you are driving an unfamiliar vehicle. Those three cover most of the calls we take.
M1 junctions 33, 34 and 36, the Parkway, Penistone Road and the A61. People filling up in a hurry on a route they do not normally take.
By some distance the highest-risk group. You have driven a diesel for years and the hire car is petrol, or the courtesy car from the body shop is the opposite of your own. If you drive a van fleet, it is worth having one rule: whoever fuels it checks the cap, every time.
Meadowhall, the retail parks and the big supermarket stations, where the pump layout puts petrol and diesel side by side and the nozzles are the same colour on some brands.
Six answers and we can tell you what happens next, what it will cost and roughly when we will be with you.
The forecourt name and road, or a postcode. If you have already pushed it clear of the pump, say where it is standing now.
The single most important question, and there is no benefit in being vague about it. If it started, even for a few seconds, say so. It changes what the garage needs to do, not what we charge.
Make, model and roughly how old. Whether it is petrol or diesel, and which one went in.
Your own garage, a main dealer, or somewhere that does fuel drains. If you do not have one in mind, say so and we will suggest options rather than pick for you.
Forecourts are usually straightforward, but a car boxed in between pumps or against a shop front is not. Tell us if there is a canopy height limit, which there often is.
Sheffield and all of South Yorkshire, including the M1 corridor from junction 30 to junction 37, the Parkway, Rotherham, Barnsley, Doncaster, Chesterfield and the border villages. Wherever you filled up, we can usually reach you.
Do not start the engine, and do not put the key in the ignition on a keyless car. Tell the forecourt staff, put the vehicle in neutral and push it clear of the pump if it is safe to do so, then call us. If the engine has not run, this is usually a drain and the car drives away afterwards.
Not necessarily, but stop driving now rather than trying to reach home. In a diesel, petrol strips the lubrication from the high pressure pump, and the further you drive the more of the fuel system is affected. Pull over safely, switch off, and call. The honest answer on cost comes from the garage after they have looked, not from us at the roadside.
No, and be careful of anyone who says they can do it properly on a forecourt. Draining and flushing a fuel tank is a workshop job with the right equipment and safe fuel handling. What we do is move the vehicle there without the engine running.
No. Diluting the wrong fuel does not undo it and makes the drain more awkward. The same goes for additives. The tank has to be emptied.
It depends where you are, where the vehicle is going, the time of day and what we are recovering. Call with those details and you will have a figure before we set off. The fuel drain itself is charged separately by whichever garage does it.
Sometimes. Misfuelling is a common exclusion on basic breakdown cover and a common inclusion on comprehensive insurance, so it is worth the two minutes to check your policy before you assume either way. Our look at whether breakdown cover is worth it covers what these policies usually do and do not include.
