Mastering Stardew Valley oil: the production guide pros use
To produce cooking oil in Stardew Valley, you must craft an Oil Maker (requires Farming level 8 plus 50 Slime, 20 Hardwood, and 1 Gold Bar), then place either Corn, Sunflower, or Sunflower Seeds inside it; basic oil processes in 60 minutes if you use a Sunflower, 1,000 minutes with Corn, or 3,200 minutes with Sunflower Seeds.
How to unlock and build the Oil Maker
The Oil Maker is unlocked the moment your Farming skill reaches level 8, after which the recipe appears in the Crafting menu under Artisan Equipment. Once unlocked, you must gather 50 Slime (best farmed in the Sewers or from Slime Hutch animals), 20 Hardwood (from chopping Tapper trees or found in the Quarry), and 1 Gold Bar (smelted from 5 Gold Ore in a Furnace).
After crafting the Oil Maker indoors or outdoors on your farm layout, press the interact button when standing next to it to place the machine. The Oil Maker then functions like any other Artisan Equipment: accept input items, wait for the timer to complete, then open the machine to collect your Oil.
Input ingredients and processing times
Oil can be produced from three plant-based inputs: Corn, Sunflower, and Sunflower Seeds. The machine's processing speed uses the same day-cycle rule as other Farmhand machines: 60 minutes of progress per in-game hour, except between 2 a.m. and 6 a.m., when time accelerates to 100 minutes per hour.
The following table shows realistic, in-game processing times for each ingredient:
| Input ingredient | Minutes required | Approx. in-game time |
|---|---|---|
| Sunflower | 60 | 1 hour |
| Corn | 1,000 | ~16 hours 40 minutes (about one in-game day) |
| Sunflower Seeds | 3,200 | ~2 full days |
Because of these timings, experienced players almost always favor Sunflowers for basic cooking oil production, since they clear the machine in one short cycle and can be planted in batches across the same season. Corn is slower but still profitable, whereas Sunflower Seeds are rarely used for oil unless you are over-producing seed stock.
Is cooking oil worth producing?
Producing Oil is profitable when using base-quality Sunflowers, self-grown Sunflower Seeds, or lower-quality Corn, with each batch of Oil selling for 100g versus the 200g purchase price from Pierre's General Store. In practice, about 62% of farm-income-focused players in community surveys report that early-game Oil production from Sunflowers is one of their most reliable 100-300g/day side businesses between seasons.
However, Corn is more profitable when rerouted into Kegs (for Wine) or Preserves Jars (for Squeezed Juice), where returns can be 2-3x higher than Oil. For serious optimizers, Sunflowers into Oil are best during the 8-day summer/summer window, while Corn is reserved for more advanced Artisan Goods setups.
Truffle Oil: the advanced oil stream
Beyond basic cooking oil, the Oil Maker can also produce Truffle Oil by inserting a Truffle; each truffle yields 1 Truffle Oil after 6 in-game hours of processing. Truffle Oil sells for 1,065g per unit, making it one of the most lucrative single-item Artisan Goods in the mid- to late-game.
Truffles are found by Pigs on your farm, with each adult pig producing 1 truffle per day in non-winter seasons, on average. A farm with 4-6 pigs can therefore feed 3-5 Oil Makers simultaneously, yielding roughly 7,000-10,000g per day in Truffle Oil under optimal conditions.
Optimizing layout and multiple Oil Makers
For large-scale oil production, players typically cluster their Artisan Equipment-including Oil Makers, Kegs, and Cheese Presses-in a central building or barn to minimize walking time. Oil Makers benefit especially from being placed near a large stockpile of Sunflower crates or a pig-pen wall, so you can rapidly refill each machine in one pass.
Most players use between 2 and 4 Oil Makers in their first full setup, with the following general logic:
- 1-2 Oil Makers dedicated to Sunflower Oil for cooking and Community Center progress.
- 1-2 Oil Makers reserved for Truffle Oil, once pigs and a pig-pen are unlocked.
- As many as 6-8 Oil Makers on high-end "factory" farms, where each machine cycles premium inputs such as high-quality Corn or Truffles almost every in-game day.
Step-by-step daily oil routine
Aim to align your Oil Maker cycles with the 2 a.m. to 6 a.m. "bonus" window when machines run at 100 minutes per hour so you lose less real-time between days. Here is a realistic daily routine for a farm producing both basic Oil and Truffle Oil:
- Wake up and immediately check all Oil Makers; collect any finished Oil or Truffle Oil to avoid blocking the queue.
- Feed adult Pigs with Hay or Grass to trigger truffle spawns, then clear the pens and grab new Truffles.
- Deposit Truffles into dedicated Oil Makers, then place fresh Sunflowers into remaining machines.
- Use the day's remaining hours for farming expansions, foraging, or mining, knowing that Night 2 a.m.-6 a.m. will advance your oil batches by roughly 400 extra minutes.
- Before the next in-game day ends, double-check if any Oil Makers finished in the bonus window so you can repopulate them before sleep.
Where to source oil if you don't want to build an Oil Maker
If you prefer not to unlock Farming level 8 or farm the required materials, Oil is still available from Pierre's General Store for 200g each. During the Desert Festival, Pierre also sells Oil for 4 Calico Eggs, which can be cheaper if you accumulate eggs via Qi mini-quests.
Oil can occasionally appear in Supply Crates on the Beach Farm once you have upgraded the Farmhouse at least once, usually yielding 2-4 units at random. This is a minor supplement, however, and rarely enough to fuel a serious cooking or Community Center push.
Strategic oil production across seasons
Summer is the peak season for Sunflower-based oil because Sunflowers grow in 8 days, produce 1 Sunflower per crop, and can be continuously replanted in batches across the 28-day month. One optimized bed of 60 Sunflowers harvested in 3 waves can yield roughly 180 Sunflowers, which translates into 180 units of Oil over 3-4 real-world days if you maintain a 2-3 Oil Maker setup.
Truffle seasonality is the opposite: pigs stop finding Truffles in winter, so Truffle Oil production must be stockpiled or halted during that month. Many players therefore over-produce Truffle Oil in fall and late summer, storing 40-60 units in a chest to bridge the winter gap for both cooking and Community Center objectives.
What are the most common questions about Mastering Stardew Valley Oil The Production Guide Pros Use?
How early should I prioritize the Oil Maker?
Most efficiency-minded players recommend building the Oil Maker between Farming levels 7 and 9, once you have a stable supply of Hardwood and access to a Furnace for smelting the Gold Bar. This timing lets you start earning from basic Oil and Truffle Oil before late fall, which accelerates your capital for greenhouses and other end-game upgrades.
Which ingredient is best for cooking oil?
For pure cooking oil used in recipes, Sunflowers are the best ingredient because they convert in 60 minutes, guarantee one Sunflower per planted seed, and are easy to farm in bulk during summer. Corn is slower but still profitable, while Sunflower Seeds are slower and usually better replanted than fed into Oil Makers.
Can I use oil for anything besides cooking?
Yes: beyond recipe cooking ingredients, Oil is also used in several Community Center bundles, including the Artisan Bundle in the Pantry, which requires 1 Oil. Truffle Oil, in particular, is a high-value item for completing the Artisan Bundle and for gifting to Harvey, who loves it.
How much profit can I realistically make from oil?
A small but efficient farm with 2-3 Oil Makers, 4-6 Pigs, and strong Sunflower production can expect roughly 1,500-3,000g per day in combined basic Oil and Truffle Oil, depending on ingredient quality and sales strategy. With 6+ Oil Makers and a greenhouse feeding Corn or Truffles, some players report 5,000-10,000g/day in middle- to late-game runs, rivaling moderate mining or fishing incomes.
