Chili oil is a completely different condiment, as it doesn't have the acid, but it's also often 0mg of sodium. I quite like S&B brand, but there are many Chinese varieties that are quite tasty.
A secret of mine is sesame oil. Delicious, also with no sodium. I use it almost as a soy sauce substitute (but even still at much lower quantities due to the calories/fat). It’s not salty at all, but has a certain punch that I like for similar foods.
I have ones for cooking oil, olive oil, chili oil, and sesame oil... the chili and sesame in easy-to-use, flavorant amounts are great to dash into vegetables or a salad or whatever, and having it atomized instead of drizzled makes it so much better and more convenient!
