Crude Oil becomes a resource you cannot ignore once you start pushing into the later technology tiers, and the easiest way to keep a steady supply is to dedicate a whole base to it. The Sakurajima update raised the number of bases you can own, which means one of your free slots can sit on top of two Crude Oil extraction points and pull in Coal, Sulfur, and Stone at the same time. Sakurajima Island holds several spots that do exactly that.
Quick answer: Place a base at coordinates (-513,186), (-371,133), or (-646,270) on Sakurajima Island. Each one fits two Crude Oil Extractors and sits on high or cliff-shielded ground, so raids can only reach you from a single side.
The three best Crude Oil base spots and what each one gives you
All three locations support two Crude Oil Extractors, which is the main reason to build here. The differences come down to how the extraction points are spaced, which extra resources sit inside the base radius, and how well the terrain blocks raids.
| Coordinates | Extra resources | Raid protection |
|---|---|---|
| (-513,186) | Multiple Coal deposits | Cliff on one side; open only at the front |
| (-371,133) | Coal, Sulfur, Stone | High ground with steep cliffs into water on two sides |
| (-646,270) | Coal, Sulfur, Stone | High ground; one open approach |
Location at (-513,186): two extractors plus heavy Coal
This spot fits two Crude Oil Extractors, and the two extraction points sit far apart. That gap leaves plenty of open floor between them, so you have room to add a Mining Station and turn the base into a full resource farm rather than a single-purpose oil rig. A cliff covers one side, which leaves the front as the only open approach and keeps most raids predictable.
The nearby Coal is the standout here. Multiple deposits fall inside the base radius, so mining Pals can pull Coal and Crude Oil from the same location without you shuffling between bases.
Location at (-371,133): Coal and Sulfur on a cliff top
Sitting on top of a cliff, this base pairs two Crude Oil extraction points that are placed right next to each other. That tight spacing keeps collection and storage simple. The bigger draw is access to two rarer materials at once, Coal and Sulfur, along with Stone.
Defensively, it is one of the safer picks. The high ground drops off steeply into water on two sides, and one edge leads to a dead end, so raids can realistically only come from a single direction.
Location at (-646,270): the same resources with cleaner surroundings
This location matches the previous one in function. It offers two Crude Oil extraction points and an abundance of Coal, Sulfur, and Stone inside the radius. The base sits on high ground, which already makes it a reasonable defensive position, and it backs onto the Sakura Blossoms for a calmer setting if the look of your base matters to you.
How to set up the base for steady output
Note: The extraction points and terrain here are tied to Sakurajima Island, so you need access to that region before any of these coordinates are usable. Once a base is running, you know it is working when the Crude Oil Extractors are actively pulling oil and your storage begins filling with Coal, Sulfur, and Stone from the surrounding nodes.
