I always get a kick out the “different” oils. Years ago I walked into a metering building on the backside of the island. This is where multiple oil wells feed from the Gulf. The meters were for Exxon, Mobile, Texaco, Chevron, and several I don’t remember. All basically coming out of the same field.
I got one better than that. 95% of all fuel comes into Humboldt Bay from Chevron at Richmond Ca by barge and is distributed by tanker truck to all the branded and independent stations in Humboldt and Del Norte counties...
