Regardless of how indifferent many of the BP investors are to the Macondo spill and their atrocious refinery safety record, I for one will continue to boycott all BP products including Castrol motor oils. I may be only one potential customer but I will never forgive or forget. Likewise ExMo remains on my embargo list.
Don't forget to add Shell (Nigeria!), Conoco (Alaska spills), Total (total disaster), any oil imported from Saudi Arabia, Russia (countless disasters), any generic brand that obtains its products from the above or oil from planet earth and produced by earthlings. Those earthlings are patently imperfect. DO NOT TRUST THEM. I only buy from Klingons myself.
