These Are The 4 Easy Ways To Distinguish Diesel Cars From Petrol Cars



Telling apart a diesel powered car from petrol powered car is easy when you know exactly what to do. As an individual knowledgeable in things related to automobile, you should know this.
In this part of the world, petrol cars dominate diesel cars; be it as it may, no knowledge is a waste.

Below are the various 4 ways you can tell petrol cars apart from diesel cars.

1. The sound from the car:
Petrol powered cars produce smoother sound when compared to diesel cars. The sound from the diesel engine is somewhat unpleasant. Sounds more like a tractor. You will hear a rattling sound when a diesel car is idling and this becomes raspier when you start driving it.
Recent technologies in diesel engines have curbed this. Most recent diesel engines don’t make such noise.

2. The fuel cap label:
Diesel powered cars would always come with a label reading ‘Diesel Fuel Only’ or ‘Diesel’  inside their fuel doors.
This alone will tell you it’s a diesel car. Cars that run on fuel do have ‘Gasoline Only’ written on their fuel door.

3. The model name:
There could be a clue in the model name of the car. It is yet another easy way to identify a diesel car. A diesel powered car is likely to come with the letter ‘D’ in its model name. For example, if you see a car that has BMW 320d or Lexus IS 220d, the ‘D’ tells you it is a diesel powered car.

4. Peep into the engine:
Diesel cars have no spark plugs. The pressure from compression of diesel and air is enough to give them the ignition that a spark plug would do for petrol engine.
