I have not only read this, but I have tried and proven it. Peanut oil, if you can use it, is the best for making oil. I have made many batches of oil, and have found it works much better and produces a better product. I also suggest using a crock pot. they make them in many sizes. This allows you to slow simmer the oil, not boiling it, and for longer period of time depending on the quality of ingredient X. You can use a large quantity of stems from good quality plants. They contain alot of crystals. I also suggest, if you use a grinder with collection tray, use the keif powder. That is ultimatly what you want to use, and there is no need to strain. 2g of powder will work perfect for one bottle of oil, then dilute oil needed for cookies/brownies by half. i suggest recipes that call for 1/2 cup as opposed to 1/3. Betty croker has an oatmeal cookie bag mix that works great. And remember, always make a batch of square cookies for snacking on later.
