Yes: "For other purposes" is what I meant to enter.
I was wrong, or at least it looks that way.
It appears that I either mis-remembered the article or misread it. When I do a quick google search it shows that way over half of oil is used for transportation and only a small part is used for Plastic production.

is the following:
...Besides, passenger vehicles consume only about 26 percent of the oil used worldwide.
So that might have been part of my misunderstanding.
