Does propane fumes smell like car exhaust fumes?

No, propane fumes do not smell like car exhaust fumes. Propane has a distinct odor that is often described as "skunky" or "sulfurous." Car exhaust fumes, on the other hand, have a strong, pungent smell that is caused by a combination of chemicals, including carbon monoxide, nitrogen dioxide, and hydrocarbons. While both propane fumes and car exhaust fumes can be unpleasant, they are easily distinguishable from each other by their odor.
