Saw some STP motor oil at Dollar general while trying to see if they had any Trop-Artic. The STP oil is GF-4 API SM. Anyone else see the STP oil yet or know who makes it?
Clorox has a bunch of companies and brand names that they've purchased over the years. Kingsford charcoal, Pine-Sol, Armor All, Brita (at least for the US), and Glad.quote:
