Cooking Oils

So one thing that piqued my interest a while ago was oil. I know olive, vegetable, canola and other common ones like that but I wanted to know what else was out there and what I could use it for.

  
Here are a few links I found:
Whats Cooking America
Whole Foods Market

But what about substitutes? My grandma always swapped out the oil in a bake mix for applesauce, which works. Here are some healthier alternatives to oil:
Vegetable oil- for baking: 1-1 applesauce or fruit puree
Vegetable oil- for frying: 1-1 lard or vegetable shortening
On a vegan webpage I found:

• Apple sauce may be used in cakes, cookies, and other sweet baked goods to replace oil or margarine.
• Prune Puree may be used to replace the oil. To make it, puree in blender 6 ounces prunes, 1 cup water, and 2 tsp. vanilla.
• Mashed or pureed tofu can replace oil in other (non-sweet) baked goods.
• Flax meal can replace all or some of the oil in a recipe. The substitution ratio is three parts flax seed meal for every part oil or fat you are replacing. For example, for 15 mL (1 Tbsp.) of fat to be replaced, use 45 mL (3 Tbsp.) of flax seed meal. Baked goods with flax as a fat replacer tend to brown more quickly than regular recipes, so you may have to modify normal cooking times.

 Know any other good oils to use of good substitutions? I would love to know about them.
