Q: Gasoline inside the car?

asked by on January 31, 2017

A very strong gasoline smell (or maybe it's car exhaust) entered inside my car yesterday. (Probably because its cold outside and I haven't driven it in a while) I had to be outside away from the car while letting it warm up. Eventually as the car warmed up and air entered the car, the gasoline smell went away. After letting the car run a little bit longer, I shut it off, opened all 4 of the windows about 1/6 of the way down and let my car stay outside and let the fresh air ventilate the car for about 12 hours. I was wondering if this gasoline gas or car exhaust can 'stick' to my car and the items in it. I am concerned gasoline gas or car exhaust will be on my items, making them harmful to touch. I had clothes, a paper books, bags, and other stuff inside the car. There was a lot of gasoline/car exhaust inside the car and the smell was really strong inside. So is my car safe to drive and is all my stuff safe to use (especially the books and clothes)? I have leather seats if it matters.

The first concern is whether you could have an exhaust leak or a fuel leak. If leaks of that type exist, they should be repaired as both are safety hazards. Occasionally, just due to the weather, exhaust fumes can get drawn into cabin air. At no time, however, is it normal for significant amounts of raw gasoline to be in the air, or leaking as a liquid, especially on a modern car which has sophisticated systems to capture any potential fugitive emissions of vaporous gasoline. If this was a one-off incident, and just limited to exhaust odor, not to worry but if you regularly detect the distinct odor of raw gasoline, that should be investigated at once because leaking gasoline is a fire/explosion hazard. As far as damage to personal belongings from exhaust or gasoline vapors, in ordinary concentrations and if the exposure is fleeting, there is no damage potential. The reason is gasoline is highly volatile and so evaporates into the atmosphere. However, if you spill liquid gasoline on materials, the non volatile compounds will be around for a long time and indeed will destroy many common materials as gasoline is a highly aggressive solvent. Most of the hazard from gasoline vapors is not to personal property but rather to your health because gasoline contains known, well documented carcinogens such as benzene. So, the bottom line is fleeting exposure to the vapors will not damage property but will damage your health.
