Fallout 4: Vendors Who Sell Shipments of Oil
When you play Fallout 4, you may find yourself running low on the essential and rare mod, oil. There are 3 vendors who sell shipments of oil: Trashcan Carla, KL-E-O, and Proctor Teagan. Their stock is replenished every 2-3 days, so simply, do a run of these 3 vendors: eat, sleep, and repeat.
1. Trashcan Carla (location: On Road Between Sanctuary and Drumlin Diner)
2. KL-E-O (location: Goodneighbor [Guns, Guns, Guns])
3. Proctor Teagan (location: Prydwen).
