While not particularly good, it's not bad either: I'm immune to the smell of cow dung. Pig, sheep, horse, etc smell horrible. But Cow shit is perfectly OK. Guess which animal I grew up with.
New car smell, it's awful. Sort of stale plastic if I were to describe it.
Amplified by long trips on bad roads as kid. Guaranteed to make you feel like vomiting on some sections. Now when I anticipate/pack for a trip I tend to smell that again even though I'm not even in a car.
I love the smell of wood burning/camp fire smell. There's something I find comforting about it. I've yet to find a candle that exactly replicates the smell, but if I ever do, I'm buying 50.
I like the smell of moldy houses. I've been told it's a health hazard, so I don't engage or encourage it, but when people excuse the smell in their residence, I tell them I like it.
Motor oil is a smell that I really like. It's from growing up around mechanic shops, I think.
I hate the smell of sandalwood. It's just overwhelming and I can't get past the heaviness of it. My coworkers use a tobacco and sandalwood scented room spray and I want to gag every time.
I love me some fried food; I get nauseated smelling the oil itself while things are cooking though. It's worse depending on the oil or fats used. Straight butter and eggs frying in a pan is the worst.
I do janitorial work at McDonald's in the mornings and I always wait until after the switch to lunch to really clean the kitchen because the smell of the eggs being fried makes me wanna puke.
Dislike lavender. I once passed through a town that produces a lot of lavender, has a festival for it and everything. It was so awful. Lovely area, though.
Cooking chicken and cooking fish just immediately makes me want to gag
Might have ARFID for those things, but I've also got a really weird social anxiety about food in a social context, so it just compounds how put off I am when I smell fish or chicken cooking
I remember liking the smell of diesel exhaust as a kid but now, at least here in Japan which may have different emissions, it makes me feel like I can't breathe.
Petrichor is fantastic as is the smell of the ocean. Cow manure is super nostalgic to me. I was driving my motorcycle to do some paperwork in the city and smelled them putting it on the fields. An ocean away, but still felt like my childhood home.
Cilantro/coriander leaf (and whatever thing in my property smells oddly like it when I cut grass/weeds) is like bug spray to me. Can't stand the smell. A tiny bit in something doesn't put me off, but it quickly gets unbearable and chemically to me.
Like: Chlorinated water smell, so yes bleach, there was a chlorinated water fountain in a building I used to work in and I would just go sit by it and smell it, so relaxing. Pot and tobacco both smell so good before they are burning, too, but the smoke, no, yuck.
I like the smell of other people. We work so hard to scrub ourselves clean, but I like to smell of people, even sweaty. I ask my spouse not to shower too often, lol. (Not trying to ask them to be super stinky... just a little favor.) I sneak a little smell every time I hug my kids.
IDK if this is popular or not, but I never hear anyone talk about it, so *shrug*
I agree with you on gasoline. I also enjoy the smell of the blue liquid you put in your car and then spray on the windshield (I don't know what it's called).
Asafetida. People call it horrible unless cooked but imho it just smells like garlic++. It's sulfurous, but so is garlic and a lot of food really. Sulfur isn't necessarily an unpleasant smell to me. As far as I can tell the smell of asafetida doesn't change when cooking, it just gets milder.
Healthy compost also smells kinda nice, rotting meat is awful but if you're not getting putricene and co from anerobic nitrogen decomp decay mostly smells damp and warm and spicy.
Durian also smells amazing, but that's a pretty popular opinion given the wild popularity of the fruit. Potentially more sulfur not aversive stuff there.
In the hate camp peanut butter. It is overpowering and early in the day makes me throw up. My wife adds it to coffee sometimes which makes the entire house smell of peanut butter for hours. It's a very powerful and cloying smell.
I generally feel like my sense of smell is quite bad. There's not really a lot of smells that I hate abnormally, probably due to the reduced sense of smell. I do like gasoline smell just like you, but honestly I thought that that was normal.
I love the smell of basements. The humidity and the green, decades old moss on the wall gives off this refreshing yet mature scent. As a plus, it's also often cooler than the air at ground level. Mmmm.
I grew up in a post-Soviet European suburb where almost everyone kept some kind of farm animal. The smell of chicken manure gives me the good kind of nostalgia.
On the negative side, both the smell and taste of strawberries is offensively generic.
I love the smell of first time firing up a brand new toaster. I've only experienced this like 3 times in my life but it's immediately recognizeable and very pleasant smell. Some protective oil on the coils I assume.
Another is suede or something similar. I can't quite pinpoint the exact source of it but I remember my cousin's doll house having this kind of "electric" smell to it and now few years back I bought this used leather jacket that smells quite similar.
Also the battery compartment of most remotes.
EDIT: This isn't even answering the question but whatever
I also like the smell of gasoline and bleach, most likely from the association with riding dirt bikes and swimming as a kid. Fuel for the bike and bleach to clean the tshirts before going for a swim in the public pool!
I like the smell of ammonia. I use ammonia based cleaners almost exclusively. Bleach smells like nothing to me, like if TV static was a smell.
I dislike strong perfumes, and I hated doing laundry for a long time and would put it off as long as I could before my grandma introduced me to scentless detergent. I don't use scented dryer sheets either. I shouldn't be able to smell my clothes after a wash. It's gag-inducing.
Love the smell of n-hexane and pet ether (worked in a chemistry lab). Though don't like the smell of gasoline. I kind of also like the smell of chlorinated water. Also chloroform, though not as much as n-hexane.
In college, I worked at a little aerospace manufacturing place running an NC milling machine, and I really like the smell of the cutting oil/lubricant they spray on the rotating cutters. I now work in software engineering at a company that makes rocket engines, and I like walking through the shop and smelling that smell.
I love the smell of dittos, it's unlikely I'll ever smell that again. I also love the smell of garages.
I hate the smell of food after I've finished a meal. Every weekend I make protein blueberry pancakes. The house smells delicious until I'm done eating, and then it feels cloying.
I reaaallly hate the smell of other people, except my husband. I feel like I have an extra strong sense of smell, and I really hate the scalp smell some people have, especially during a humid summer. Nauseating! And forget about it if I can smell your feet through your shoes, I will definitely make some excuse and leave. And body odor, especially from people who don't use deodorant or shower every day. I know that's a personal choice and I should be tolerant but it's so overpowering, I really hate it.
Now that I think about it, I guess these aren't too uncommon after all.
Love the smell of petrichor, the smell of the world after a good rain, especially if the temperatures are cool and crisp. Bonus if it’s deep in the temperate rainforests of the Canadian PNW, with no civilization near.
Love the smell of fresh-cut grass, reminds me of my youth even if it’s one of the only things that makes me sneeze uncontrollably (my only known allergy).
Marigolds bring me all the way back to childhood, as my mother had them planted around the entire house. I take one whiff, and for the briefest of moments I am a five year old without a care in the world. To this day I collect and re-sow their seeds everywhere I can. I particularly like the small ones with the dark orange and deep crimson flowers.
Hate the smell of tar with every fibre of my being. I could never be a roofer or a road worker or a street resurfacer for that reason. It makes me gag uncontrollably with even the faintest whiff.
