Please don't do that here. This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html. Your comment would be just fine without that bit (and the final bit).
Cars are not really made of oil, gasoline is. And this was probably not the best of examples. In most oil companies extraction/exploration (raw material) and refining (processed product) actually split the profits pretty evenly, all things considered. Marketing (gas stations) gets pretty much the breadcrumbs and relies for profit more on selling Coke and sandwiches than actual gas.
This is unlike most other cases where the raw materials are worth far less than the processed ones, and the bulk of the profit goes to the final manufacturer rather than the raw material exporter.
It's equivalent to saying the oil producing companies only get x% of global car sales. Simply, ridiculous statement.
