From their website:
Nickey Petroleum Company has been a family operated business for over 80 years. We operate our own fuel terminal, and a fleet of tankers which deliver fuel, from 500 to 10,000 gallons, to commercial, agricultural, and industrial businesses throughout Southern California.
We carry product contracts with British Petroleum (B.P.), Conoco, Phillips, and others which allow us to offer the lowest prices possible to our customers. We also carry a full line of Conoco lube oil and solvents in any package size or in bulk quantities
