The following are the major causes of petrol smell:
· Fuel Cap –
A faulty or loose fuel cap might be causing the petrol fumes to escape. When the fumes escape from the petrol tank, you would easily feel the smell of petrol inside the car. If the fuel cap is faulty or even lose, it might cause the check engine light to turn on, a much-needed feature in terms of safety.
· Spark Plugs –
The spark plugs are responsible for giving the spark to turn on the vehicle. In case they are faulty, loose, or leaky, they will allow the petrol fumes to escape. Many of you can repair your car easily, and checking the spark plugs won’t be an issue.
· Oil Leakage –
If you smell the oil, stop and bring the vehicle to a halt. After a few minutes, look underneath the vehicle and see if there is any oil leakage. If not, pop open the bonnet and give it a thorough look, especially the valve cover gaskets. These gaskets are extremely prone to leakages. Even smoke from the engine is an indicator of an oil leak.
· Exhaust –
If the petrol smell is coming from the rear of the vehicle, turn on the vehicle. Next, bring your face closer to the exhaust pipe. If you can smell petrol, it is from the exhaust fumes that are unable to burn the petrol properly. In this situation, take the vehicle to the nearest workshop right away.
