If petrol has gone into your diesel truck, van, or commercial vehicle, do not start the engine. A quick fuel drain can help prevent expensive fuel-system damage and reduce costly business downtime. It happens more often than you would think. A driver grabs the wrong nozzle, fills a diesel truck or van with petrol, and…
E10 is the cheapest fuel on the bowser at most servos in Australia. It is tempting to grab it every time, especially when 95 and 98 are 30 or 40 cents a litre higher. But not every car is built to run it, and using it in the wrong vehicle can cause problems that cost…
Most wrong fuel advice out there is written for cars. But motorbikes get misfuelled too, and the situation is actually a bit different because of how a bike’s fuel system is built compared to a car’s. If you have just filled your motorbike with the wrong fuel and you have not started the engine yet,…
You are at the servo, fuel prices are painful, and you grab the 91 nozzle instead of the 95 or 98 your car is supposed to take. Maybe you did it to save a few dollars. Maybe you just grabbed the wrong one. Either way, now you are wondering if you have done something expensive…
So you are driving along in your Ford Everest, everything feels fine, and then a warning pops up on the dash about AdBlue. Maybe it says the level is low. Maybe it says the system has a malfunction. Or maybe you are reading this because something worse happened and AdBlue ended up in the diesel…
To check what fuel your car takes, look for the label inside the fuel flap first, then the owner’s manual, then the engine badge on the boot. If none of those settle it, a dealer or a registration check against the vehicle details will confirm it in a minute. Most drivers would swear they know…
Yes, physical misfuel prevention devices work. They fit inside a diesel filler neck and mechanically block a narrower petrol nozzle from entering, so the mistake becomes impossible rather than unlikely. The trade offs are fitment, cost and slower filling on some high flow pumps. It is a fair question to be sceptical about, because the…
A diesel that has run out of fuel usually will not restart straight after refuelling because air has been drawn into the fuel system, and air stops the system building injection pressure. Many modern diesels re-prime by cycling the ignition several times before cranking. Running a petrol car dry is embarrassing. Running a diesel dry…
Biodiesel is a legitimate fuel, not the wrong fuel. Australian pump diesel may already contain up to five percent biodiesel without labelling, and most modern diesels handle that without any issue. Higher blends such as B20 are worth checking against your manufacturer first. Biodiesel makes people nervous in a way that ordinary diesel does not,…
A short period of rough running immediately after a fuel drain is normal, because a little air and residual fuel remain in the lines. Roughness that continues beyond the first few minutes, or past the first tank of fuel, usually points to a fouled filter, fouled spark plugs, or damage from before the drain. The…
