Refrigerator life of nut oil

About how long should one expect oil - walnut oil in this case - to hold up in the fridge before going rancid? Any expert opinions?

A google search found a page advising storing walnut oil like you would olive oil - in a dark cabinet or cupboard at room temperature or so.

Store at 65F to 75F in a dry and odor-free environment for a shelf life of approx. 9 months in unopened containers. Opened containers should be used within 3 to 8 weeks.

I bought avocado oil for a recipe out of Cooking Light I made. (delicious spicy shrimp, but I digress) Now I have a rather expensive, rather smallish bottle - 8 bucks for 4oz. - of avocado oil and only one recipe.

I'd appreciate any alternative uses anyone might suggest. Can I just use this in place of olive oil? It's a very light, slightly nutty flavor that appears to have a very high smoke point.

You know, instructions like that drive me crazy, or at least the statement that you should only keep it for 3-8 weeks. I have some walnut oil in my fridge that is probably 3 months old. Does it taste as fresh as when I opened it? No. Is it rancid? Certainly not. I say keep it, when you have a recipe that calls for it, taste it and replace it if it tastes bad.

Honestly, we should have a repository for such perishable ingredients that are only sold in quantities too large for a home cook to use in time.

melissa,

i totally agree.
