Light olive oil IS olive oil. Different varieties and types of olive oil are used for different things, so one cannot say that a certain olive oil is better than another.
Olive oil is the healthier of the two. Olive oil is one of the healthiest oils, period.
yes you can. but it wont as better than olive oil.
rapeseed oil or vegetable oil - they have even less saturated fate than olive oil
Olive oil is known for being healthier to cook in, but it cannot withstand as much heat as vegetable oil. It will burn onto the pan. Olive oil is better used once cooking is almost done, or on raw vegetables - such as spritzing on a salad. Olive oil can be used for frying, but not high heat frying. Peanut oil, which is also a very healthy mono-unsaturated oil smokes, and burns at a much higher temperature than even some vegetable oils. Extra Virgin olive oil is highly flavorful, and very good on salads. Regular olive oil has some olive taste, but is very good for cooking. Extra light has very little flavor. All can be used for light frying.
"Light" olive oil will smoke less than "Virgin" olive oils and be fine for most frying purposes. If you want more flavor, you can use mid grade (virgin but not extra virgin), but be careful with the temperature. The highest grades are usually used for direct consumption such as in salad dressings.

Olive oil is vegetable oil, only better for you. Extra virgin has a lovely olive flavor which you might not appreciate in your biscuits, so extra light (oil NOT from the first pressing of the olives) might be a good idea. I use it and like it
Olive oil holds heat better than vegetable oil. However, all types of cooking oils are susceptible to heat damage if they are left on a burner for too long.
Olive oil (the same kind) can be used for both cooking and salad dressings. The best to use - especially for salads - is extra virgin olive oil. Extra virgin olive oil has the highest olive flavor. Regular olive oil is light in flavor, and extra light has very little olive flavor.
olive oil
vegetable oil has a higher smoke point than olive oil but olive oil has better flavor. If you're frying for a significant amount of time use vege oil, if frying for a short amt of time you can use olive. If you're in the middle you can blend olive and vege to heighten your smoke point so the olive won't burn and still get the flavor
Olive oil is made from crushed olives; sunflower oil is made from crushed sunflower seeds. They taste different; olive oil tastes of olives. Olive oil is better for you.
