The following are NOT Gulf Oil Company vessels, but are commonly mistaken due to the name:
Gulf Banker, Gulf Farmer, Gulf Merchant, Gulf Shipper, Gulf Trader. 
These were owned and operated by the "Gulf and South American Steamship Company", and not affiliated in any way with Gulf Oil.
The Gulf Ace II, Gulf Majesty, Gulf Miss, and Gulf Duke were owned by Gulf Mississippi Marine, again, no affiliation with Gulf Oil Company.
