Of course, salad oil can't be applied to your body. Salad oil is the oil we usually use for cooking, while fitness oil is olive oil. For olive oil for fitness, the bottle must be marked with "Extra virgin olive oil". Acidity < 1%, I suggest you go to a supermarket where you can buy imported goods.

Edible olive oil, usually high-grade virgin olive oil, cannot be used for fitness because of its acidity.
