I wonder too. Simply in the plastic bottle it came in, unopened, no sunlight. Was 3 years old.
It was stored in a non climate controlled place. So temperatures will have ranged quite a bit over the years (-10C to 30C are the min/max where I live). Perhaps that was a problem?
All oils will store well for about 6 months. Unfortunately most long term fats will go rancid. Anything canned will last longer.
I personally keep an extra bottle of olive oil in the freezer and rotate it when I buy a new bottle. Keeps it very fresh, and in the long term it will keep indefinitely.
Coconut oil is your best bet - it's shelf stable for 2+ years, doesn't go rancid easily, and works for both cooking and skin care in a pinch (plus those emergency power stations can keep your electric cooking going when the grid's down).
I've had sunflower oil go rancid before. Is it perhaps due to bad storage?

I keep oils in my cabinet next to the stove.
Never had issues, while my olive oil is always empty within 2 months the sunflower oil I am still using since 15 years and never had to buy a new one

It doesn't take up much space either.
