Fuel fragrance is the answer!
I can’t believe no one chimed in on this. You can buy the fuel additive in Grape, Bubblegum, Pina Colada, Watermelon, & Cherry. I am told Grape is the most fragrant. I used the grape additive. Drive into a group and people ask what is that smell? Smells like grape! Italian hence grape. I just say it runs on cheap wine. The fragrance does linger in the garage.
I think it was developed to mask race gas.
