What Makes Fuel Smell Good?

Gasoline is a complex mixture of over 150 chemical compounds, many of which are dangerous to our health, according to a public health statement issued by the CDC. The compound that gives gasoline its strong and gassy smell — which attracts some of us — is a hydrocarbon called Benzene.

Now, manufacturers don’t just add benzene to give us a little treat. The benzene in gasoline provides better fuel efficiency and improves engine performance. Perhaps the nice scent was just a happy accident.

Fair warning, the activation of the mesolimbic pathway to release dopamine is how most drugs of abuse work their evil magic. The feeling you get when there is a burst of dopamine in your system is what makes something addictive. So, casually smelling Benzene while filling your petrol tank is harmless, but intentionally sniffing it can cause addiction and health issues.

Is It Only Fuel?

Interestingly, gasoline isn’t the only thing that contains Benzene. Other common items you may have smelt that contain benzene include tennis balls, nail polish and paint. If you have ever found yourself lingering, curiously smelling these things, now you know why.

Conclusion

So, the reason you flare out your nostrils to get a nice big whiff at gas stations is because of the strong, yet pleasant smell of Benzene that’s added to gasoline. Whether Benzene does this by eliciting a fond memory, releasing a shot of dopamine, or a combination of both is still being researched.
