Hey guys. Around a week ago, I reached for the spiced oil from the fridge. A black spot of mold was on top. That was around 2 weeks after making it. I can't promise I always used a clean spoon for it however. I may have fried the onions, garlic, ginger, etc and used the same spoon to top up a little. I don't think so, but as you know, when the curries cooking, there's little time to spare!
I would also like to add that the star anise adds too much of its flavour and smell to the oil. I've never liked the use of it in Indian food - I think it doesn't work well in CA's rice either. It has a Chinese food type taste to me.
