You think like me.
I always have been a GM and Valvoline fan.
Switching oil to also keep my money in the good ole USA.
I’m old and stuck in my ways….
My guess is that Saudi Aramco bought the back-end part of Valvoline
because it was good oil. They most likely want to improve their lubricant manufacturing capability as well as increase it globally. Making the oil worse doesn't really figure in to that.
As far as "keeping the money in the US" goes, that has more or less gone out the window once international entities were allowed to buy US stocks. A company could be headquartered in the US, but have a majority of foreign shareholders. Or vice-versa.
To me, the real question isn't where the profit goes, it's where their workers are employed. And for Valvoline, that's not going to change very soon.
