All the oil is doing is helping the pan not boil over while on a high heat as it makes the formation of bubbles at the surface more difficult. So… it kind of helps because you can cook more easily at a high heat but yeah it does nothing for the pasta.
The neverending discussion about pasta, olive oil and just putting enough water... 10g salt, 100g pasta, at least 1L water e basta così ! No oil or you ruin the pasta/sauce synergy. 😃 (lemmings.world)
