The neck of the diesel tank is bigger than the gasoline tank.the diesel tank neck is about 24 cm while gasoline tank neck is about 21 cm.So the diesel pump nozzle will not fit into the gasoline tank neck easily.Secondly, it will be displayed on the tank head cap.
In the United States, unless you’re renting a large truck, it’ll be a gasoline car.
That said, virtually every vehicle in the US is marked either on the gas cap or on the filler door with the type of fuel needed, e.g. “87 octane unleaded”. Additionally, there may be a note near the fuel gauge saying the same thing.
Fuel combustion in Diesel engines is achieved by temperature rise due to fuel compression alone, without the need for spark plugs. This however means that a cold engine — i.e. one that has been switched off for a while, or one used in cold weather — might struggle to ignite at start-up. This is why diesel engines are often fitted with glowplugs. These are electronic heating devices used to preheat the engine to facilitate their ignition.
Turns out that diesel cars have a glowplug indicator which lights up when you turn on a cold engine. As you step in the car, turn the key to the “on” position, without igniting. Various indicators should light, including the glowplug one, if relevant. The glowplug indicator can therefore serve as a hint to know if your car runs on diesel, and looks like this (courtesy of Wikipedia):
If it’s a UK vehicle you can do a DVLA lookup using the car’s make and registration. It will give you a short list of information about the car. About half way down is the fuel type.
In addition to the methods already mentioned:
Have a look at the car documents.
When you start your engine, or when you have driven some meters you
will know it. A diesel sounds and feels differently from a gasoline
car.
A look at the rev meter can be revealing. The “red area” starts at
around 4500/5000 in diesel cars and at 6000 in gasoline cars.
Open the tank. Diesel and gasoline have different smells. Diesel has a typical “oily” smell.
It’s often very difficult to put diesel fuel in a regular gasoline car by mistake, the nozzle of the fuel dispenser is typically way too big. I assume there might be some international standard behind this, at least I noticed it in several countries (but I also came across some exceptions).
Making a mistake the other way around is actually not that difficult, I have seen it happen. Diesel rental cars therefore usually have prominent signs in several places, including on the little door or cap of the fuel tank itself. I also noticed this on diesel rentals in several European countries.
It’s common in Europe for many cars to have a Diesel or Gasoline version.
Usually, but it is not a rule, if the model of the car has a letter D it’s a Diesel car, but this is not a rule. It’s not a rule as well for the car to have a letter on the model name.
Usually in Diesel cars you will find some warnings about it.
