The issue with many seed oils is that the way they're produced causes rapid oxidization. Combined with storing in clear plastic bottles that don't filter out sunlight, they tend to go rancid very quickly.

For high temp oil that's fairly neutral in flavor, I would use avacado oil. Specifically Chosen Foods since the vast majority of retail avacado oils cut their product with seed oils the same way coke deals cut their product with baking soda.

I would also recommend using ghee which is basically clarified butter.
