Neither do chips, even if they all start as silicon from the ground. What the earlier comment was saying is that the actual composition of crude oil varies by location so you aren't necessarily getting the same ratio of finished products at the process. With silicon you have a bit more control over what goes into the fab. But you're still at the mercy of demand from the market.
That way? I was trying to say that the mix of hydrocarbon molecules is different for each and every oil field due to local geological variation. Even within the field, since eg lighter molecules presumably come out first.
Cracking can turn heavier oil fractions into lighter oil fractions. It's a very common procedure.
No, refineries make more heating oil in winter and more gasoline in summer driving season.
Depends a lot on the oil field, geology is random
none of those finished products come out of the ground that way.
