I know what you mean: that gassy, diesely fuel-flavor is something I look for. I was introduced to “kind bud” when I was in my mid-teens (some 30 years ago lol) and that smell and flavor profile stuck with me. Never smelled dirty diapers (lol) but I like bud that reeks like that new carpet smell.
I don’t touch indicas (the closest I get is hybrids that are sativa-dominant). They tend not to have the kick I’m looking for and just end up making me tired.
