What's up everybody!, I'm back with a new post that should probably interest you since it's a "not so documented" topic. Today we'll talk about the different types of oils and the situations most likely to be used for.
Let's get something clear first ALL OILS ARE FAT, but not all of them are created equally; there's types of fat that are good for you (monosaturated, super unsaturated or polyunsaturated) and others that you should avoid (trans fats, partially hydrogenated or with unsaturated fats). Yes, it's a little bit confusing, but after you read this you'll be able to spot them easily.
Whenever you're cooking with oil you have to consider some safety points, like if for whatever reason it catches fire you NEVER EVER try to put the fire out with water, you have to use baking soda or a good ol' fire extinguisher. If you try water it will splash and probably catch everything else on fire. If you notice an oil that starts to bubble, remove it inmediately from the heat source since it's already too hot and could probably catch fire.
On the same note, that's why we need to understand something related to this which is called the oil's "smoking point", which means the temperatures where oils begin to smoke or burn out. Why is this important?, because there are some oils that can handle a lot of heat (i.e. regular vegetable oils) and some that burn easier and can change negatively the flavor of your dishes (i.e. olive oil). This is the reason why you will never see something deep fried in butter (also it costs a lot more of course and burned things won't taste very good either).
I won't spend a lot of time explaining about temperatures and their physical properties, since a lot of people don't have thermometers anyway, so I'll dedicate more time to note which are the "good" oils and which ones you should avoid.
There are 2 main groups of oils: Refined and Unrefined:
Refined Oils (Description/Fat Type/Smoke Point):
Almond: Nut oils are best used in cold dishes; heat destroys their delicate flavor. 495°F
Avocado: This rather unusual light, slightly nutty tasting oil is considered primarily to be a novelty. To add a different twist to salad dressings, try using avocado oil in place of the oil you would normally use. This oil is often made from damaged and cosmetically inferior avocados. It is low in saturated fatty acids and high in polyunsaturates. 520°F
Butter, whole or clarified: This the preferred fat for baking as it adds the most flavour. It's not idea for frying since it will burn at a lower temperature than most oils, but can be used for sauteing. Try adding butter to oil for the flavor benefit of butter and the higher temperature range of oil. 350°F
Canola (A US marketing name for rapeseed oil): A light, golden-colored oil, similar to safflower oil. Low in saturated fat. Extracted from the seeds of a plant in the turnip family (the same plant as the vegetable broccoli rabe). Used in salads and cooking, mostly in the Mediterranean region and India; also used in margarine and blended vegetable oils. It has a mild flavor and aroma. It is most commonly available in a refined form. Its mild flavor and relatively high smoke point make refined canola oil a good all-purpose oil. Of all the oils, it has the least amount of saturated fat and is one of the least expensive. Monosaturated. 400°F
Corn oil : Made from the germ of the corn kernel. Corn oil is almost tasteless and is excellent for cooking because it can withstand high temperatures without smoking. It is high in polyunsaturated fat and is used to make margarine, salad dressings and mayonnaise. Polysaturated. 450° F
Grape Seed: This light, medium-yellow, aromatic oil is a by-product of wine making. It is used in salads and some cooking and in the manufacture of margarine. 400°F
Lard: Baking. 361-401°F
Olive: A monosaturated oil extracted from tree-ripened olives. Olive oils range from light amber to green in color and bland to extremely strong in flavor. Olive oil is graded according to its degree of acidity and the process used to extract the oil. Monosaturated. Unrefined 320°F; Extra Virgin 406°F; Virgin** 420°F; Extra Light* 468°F
Peanut: Made from pressed, steam-cooked peanuts. Peanut oil has a bland flavor and is good for cooking because it doesn't absorb or transfer flavors.. Its smoking point is slightly lower than corn or safflower oil. Monosaturated. 450°F
Safflower - High Oleic: A clear, almost flavorless oil made from the seeds of safflowers. Safflower oil is a favorite for salads because it doesn't solidify when chilled. Sunflower oil is pale yellow and has a bland flavor. It is a good all-purpose oil low in saturated fat and high in polyunsaturated fat. Monosaturated. 450°F
Safflower - Regular: A clear, almost flavorless oil made from the seeds of safflowers. Safflower oil is a favorite for salads because it doesn't solidify when chilled. Sunflower oil is pale yellow and has a bland flavor. It is a good all-purpose oil. Polysaturated. 450°F
Sesame: Made from pressed sesame seeds. Sesame oil comes in two varieties: light (made with untoasted sesames) and dark (made with toasted sesames). Light sesame oil has a nutty flavor and is especially good for frying. Dark sesame oil (Asian) has a stronger flavor and should only be used in small quantities for flavoring foods -- not cooking. Both varieties are high in polyunsaturated fat. Polysaturated. 410°F
Shortening - vegetable: Baking, frying. 356-370°F
Soybean: Highly refined soy oil is reasonably priced, very mild and versatile, accounting for over 80% of all oil used in commercial food production in the U.S. Almost any product that lists vegetable oil as an ingredient probably contains refined soy oil. This is a good all-purpose oil that is also used in cakes and pastries . 450°F
Sunflower - High Oleic: Made from sunflower seeds. Sunflower oil is pale yellow and has a bland flavor. It’s a very good all-purpose oil. Monosaturated. 450°F
Sunflower - Regular: A light, odorless and nearly flavorless oil pressed from sunflower seeds. Pale yellow and versatile. Polysaturated. 450°F
Vegetable Oil: Made by blending several different refined oils. Designed to have a mild flavor and a high smoke point.
Unrefined Oils (Description/Fat Type/Smoke Point):
Corn: One of the most common oils. Polysaturated. 320°F or less for all
Coconut Oil: A heavy, nearly colorless oil extracted from fresh coconuts. Used primarily in blended oils and shortenings. Used primarily in prepared, processed, packaged foods.
Grape Seed: This light, medium-yellow, aromatic oil is a by-product of wine making. It is used in salads and some cooking and in the manufacture of margarine.
Nut (walnut, hazelnut): This fragrant full-flavored oil is pressed from hazelnuts and takes on the flavor of roasted nuts. The nuts are often toasted for a browner color and better flavor. The nuts are never blanched. Used in salad dressings, sauces, baked goods, and for sautéing. Polysaturated.
Olive: Sauteing, stir-frying. A monosaturated oil extracted from tree-ripened olives. Olive oils range from light amber to green in color and bland to extremely strong in flavor. Olive oil is graded according to its degree of acidity and the process used to extract the oil. Oil labeled "virgin" is cold pressed, a process using no heat or chemicals and contains low levels of acidity. Oil labeled "pure" uses heat and chemicals to process olive residue from subsequent pressings. Oil varies in weight and may be pale-yellow to deep-green depending on fruit used and processing. Cold-pressed olive oil, is superior in flavor to refined. Oil from the first pressing, called "virgin" olive oil is the most flavorful. Also classified according to acidity: extra virgin, superfine, fine, virgin, and pure, in ascending degree of acidity. "Pure" olive oil, and that labeled just "olive oil" may be a combination of cold-pressed and refined oil; suitable for cooking. Monosaturated.
Peanut: Made from pressed, steam-cooked peanuts. Peanut oil has a bland flavor and is good for cooking because it doesn't absorb or transfer flavors.. Its smoking point is slightly lower than corn or safflower oil. Monosaturated.
Pumpkin Seed:
Safflower - High Oleic: Sunflower oil is an excellent all-purpose oil; however, some people find its flavor too strong for baked goods and salads. It stores well and may be used instead of sesame or corn oil. This oil has a high resistance to rancidity. Monosaturated.
Safflower – Regular: Polysaturated
Sesame: There are two types of sesame oil. The oil that is made from roasted sesame seeds has a strong, distinctive flavor. It is called dark sesame or toasted sesame oil and has an intensely rich, smoky, sesame aroma; nutty taste; dark, brown color; thick consistency; and cloudy appearance. It is used a great deal in Chinese and Indian cooking. Just a few drops of this oil can add an outrageously delicious flavor that enhances many foods. Dark sesame oil is ideal for stir-fries, baking, sauces, and spreads. Polysaturated.
Soybean: Soybeans contain oil that is inefficient to extract in a natural manner; therefore, unrefined expeller-pressed soy oil is rather expensive. Unrefined soy oil has a strong, distinctive flavor and aroma -- some like it, some don't. It has a dark yellow color with a faint green tint. Unrefined soy oil is more susceptible to oxidation and rancidity than sesame, olive, or corn oil. Polysaturated.
Sunflower - High Oleic: Made from sunflower seeds. Sunflower oil is pale yellow and has a bland flavor. It is a good all-purpose oil. Polysaturated.
Sunflower - Regular:
Vegetable (soybean): An inexpensive and all-purpose blend of oils made from plant sources such as vegetables, nuts and seeds. Most vegetable oils are made from soybeans. Polysaturated.

Unrefined oils are not good for high temperatures, so if you plan to deep fry something, just keep an eye on the temperature and don't let it burn!; but these oils are great for dressings.
Tip: if you use a lot of oil to fry, you can re-use it again!, you just have to strain it to take out most of the frying particles left, seal tightly and then store in a refrigerator. You can use oil 2 times if you keep it from burning up (if it's all burned up the flavors will be awful).
I’ve got at home a regular vegetable, avocado, extra virgin olive and grape seed oils, with these they give me the flexibility to cook different dishes (and butter) trying to highlight flavors and to improve recipes. Also, always avoid margarine since it’s only chemicals and mostly bad for you.
Remember: never throw oil out the drain, every drop of oil you throw out, it can contaminate 1 cubic meter of fresh water (that's 1,000 liters to you mathematically challenged lol). Try to recicle it!!!!
Hope this is as helpful and educational as I think it is!, if not, just let me know!!!!
