An intense sense of petrol inside the car is not just unpleasant – it could also be a symptom of a serious problem that’s caused by a number of possible causes. Some of these can be downright unpleasant if not addressed, while others can also be dangerous.
This post could help you identify the possible reasons behind strong smell of petrol in car and recommend the things you need to do to keep your vehicle safe and sound.
Topic Summary
Causes of Strong Smell of Petrol In Car
The most common reason is a fuel leak. The leak could be from the fuel tank, fuel lines, or injectors, or it could be coming from another part of the car, such as a faulty fuel injector, damaged fuel tank vent, or faulty fuel pressure regulator.
Other factors could also cause the smell of petrol. Reacting right away to fix one of these problems is crucial for both safety and car functions.
Fuel Leak
Description: The reason for the smell of petrol could most likely be a fuel leak. It could be a problem with the fuel tank, the fuel lines, or the fuel injectors.
Signs: Puddles of petrol under your motor, fuel markings on the walls of your garage, or noticing your tank hasn’t dropped as much as you’ve been covering.
Faulty Fuel Cap
Description: A damaged or improperly secured fuel cap can allow petrol fumes to escape.
Signs: If the fuel cap tight, or the seal worn then replace it.
Evaporative Emission Control System (EVAP) Issues
Description: Exhaust gas recirculation (EGR) system. EVAP system recaptures fuel vapors. A faulty EVAP can lead to petrol fumes seeping into the cabin.
Signs: A check engine light usually accompanies EVAP system issues. You can pinpoint this problem with a diagnostic scan.
Damaged Fuel Injectors
Description: Fuel injectors deliver fuel into the engine. If they get damaged, they can release petrol fumes.
Signs: Poor engine performance and fuel economy can indicate issues with fuel injectors.
Exhaust Leak
Description: It’s less likely, but an exhaust leak could still have a petrol-like smell, in particular, if close to the engine bay.
Signs: You’re listening for unusual noises from the exhaust system, and you’re looking for external signs of damage or leaks.
Steps to Take if Strong Smell of Petrol In Car
Ensure Safety First
- First Aid: If the smell of petrol is strong while driving, pull over to a safe place, turn off the engine, and avoid smoking or electronic devices.
Inspect for Visible Leaks
- Check Under the Car: For visible fuel leaks, look under the vehicle for signs of dripping or wetness. If you see the ground look wet or oily. Do not try to drive the car, but rather call for roadside assistance.
Check the Fuel Cap
- Cap it: Make sure the fuel cap is securely fastened. If it appears damaged, replace it with a new one.
Visit a Mechanic
- Doctor’s Diagnosis: If you cannot figure out what the smell is and the problem persists, make sure to have your car taken care of by a professional mechanic who can diagnose the cause and fix the problem.
Ventilate Your Car
- Air Out the Cabin: Roll down the windows and open the doors to air out the car and wear off the fuel fumes. This is crucial since you don’t want to inhale toxic fumes.
Measures for Strong Smell of Petrol In Car
Regular Maintenance
Routine Checks: You should have your car serviced regularly so that repairs can be made before they become a car catastrophe. Include a fuel-system inspection with your routine maintenance.
Monitor Fuel Usage
Watch Your Fuel-Use Meter: Obsessively watching your car’s fuel-use meter can help you spot leaks early. A big drop in fuel levels for which there’s no obvious explanation could point to trouble.
Use Quality Parts
Quality Parts: Replace failing parts such as the fuel cap, fuel injectors, or spark plugs with top-quality, new, manufacturer-spec parts — anything less can compromise reliability or safety.
What happens if you smell too much fuel?
Too much fuel vapor can be hazardous to your health. Long-term exposure to petrol fumes can lead to headaches, dizziness, and nausea.
In serious cases, inhalation of volatile organic compounds (VOCs) can lead to confusion, fatigue, and unconsciousness by displacing oxygen in the air. Chronic exposure to excessive amounts of these fumes can damage the liver, kidneys, and nervous system and may have other unknown long-term health consequences or effects.
If you suspect that you might be experiencing issues from fuel vapors, seek medical care immediately. Avoid any long-term exposure to high concentrations of fuel vapors. Ensure proper ventilation when pumping fuel, maintaining a vehicle, or filling fuel containers.
If you have a leak in a fuel storage area or in your vehicle, make sure to seal it immediately to prevent any dangerous fuel vapor concentrations from accumulating.
