1. Open the fuel tank.
2. Take a deep breath of air from the tank.
3. If the smell is strong and pungent, it is likely petrol.
4. If the smell is weak and almost sweet, it is likely diesel.
Color Test:
1. Get a clean piece of white cloth or paper.
2. Dip it in the fuel.
3. Let it dry.
4. Reddish-brown residue indicates diesel.
5. Yellowish or clear residue indicates petrol.
Taste Test (NOT RECOMMENDED)
1. Dip your finger in the fuel.
2. Taste the fuel.
3. Coughing, choking, or gagging indicates petrol.
4. Less reaction might mean diesel.
NOTE: Both tests have risks; if you're unsure, it is best to seek professional help. Incorrect identification can lead to severe engine damage if you use the wrong type of fuel.
