The Chess Oil company does not exist! The London office address they had on their web site belongs to a different company in London. The U.S. operations Office in New York also does not exist the phone number given again on their web site is a personal, unlisted number. The owner of that number had never heard of Chess Oil or any of the so called department heads. Their web site can no longer be found any where on the internet and the department heads have all but disappeared. The real owners of the London address stated that they had checked and found no company any where in the world named "Chess Oil".
