The Definitive Stardew Valley Oil Making Guide, Explained
To make oil in Stardew Valley, you need an Oil Maker, which you unlock at Farming Level 8, then feed it corn, sunflower seeds, sunflower, or truffles to produce either regular oil or truffle oil depending on the input. The fastest route for basic oil is sunflower, while the most profitable use of the machine is usually truffle oil from truffles.
How oil works
The Oil Maker is artisan equipment, meaning it converts certain ingredients into a processed good over time rather than instantly. Regular oil is made from corn, sunflower seeds, or sunflower, and truffle oil is made from a truffle. According to widely cited guide sources, the crafting recipe requires 50 slime, 20 hardwood, and 1 gold bar, and the machine becomes available at Farming Level 8.
Crafting the machine
Getting the Oil Maker is the first real bottleneck in a Stardew Valley oil-making setup. You cannot produce oil without it, so the practical guide is: level farming to 8, gather the materials, then place the machine on your farm or in a shed for organized production. The machine is especially useful in midgame and late game because it turns low-traffic inputs into reliable income or cooking supplies.
- Unlock requirement: Farming Level 8.
- Crafting cost: 50 slime, 20 hardwood, 1 gold bar.
- Main outputs: regular oil and truffle oil.
- Best-value input: truffles.
- Fastest regular-oil input: sunflower.
Best inputs
The most important choice in oil production is what you put into the machine. Sunflower is the fastest regular-oil input, corn is convenient because it is common and crops multiple seasons, and sunflower seeds are a slower fallback. Truffles are in a separate tier because they generate truffle oil, which has far higher value than regular oil.
| Input | Output | Typical use | Relative speed | Typical value |
|---|---|---|---|---|
| Sunflower | Oil | Fast processing | Fastest | Regular oil value |
| Corn | Oil | Easy farm supply | Moderate | Regular oil value |
| Sunflower seeds | Oil | Backup input | Slow | Regular oil value |
| Truffle | Truffle oil | High-profit artisan good | Fast | Highest value |
Step by step
This Stardew Valley process is simple once the machine is unlocked, but many players miss the practical order. Use the steps below to set up production efficiently and avoid wasting high-value inputs.
- Reach Farming Level 8 to unlock the Oil Maker recipe.
- Collect 50 slime, 20 hardwood, and 1 gold bar.
- Craft the Oil Maker at a crafting station.
- Place the machine in a convenient spot near crops or barns.
- Insert corn, sunflower seeds, sunflower, or a truffle.
- Wait for processing to finish, then collect the oil.
Profit and timing
For a basic money strategy, regular oil is decent but not special, while truffle oil is one of the strongest artisan products in the game. Several guide sources report regular oil selling for 100g and truffle oil for 1,065g, which makes truffles dramatically better as a production input. The tradeoff is access: truffles require pigs, so the best oil operation is usually a barn-based animal economy rather than a crop-only farm.
"Use the Oil Maker when you want reliable artisan income, but reserve truffles for the highest returns."
What to use it for
Oil is not only a sellable item; it also has utility in crafting and cooking. Regular oil can be used in recipes and some tailoring combinations, while truffle oil is commonly prized for its sell price and certain quest or cooking uses. In practice, many players process corn or sunflowers only when they need quick oil, and save truffles for profit maximization.
Common mistakes
The most common mistake is assuming every crop can become oil. Only the supported inputs work, so throwing random vegetables into the Oil Maker will not help. Another mistake is selling truffles raw instead of converting them, because the artisan upgrade usually produces a significantly better return.
- Do not confuse regular oil with truffle oil.
- Do not use the Oil Maker on unsupported crops.
- Do not sell truffles raw if you have spare Oil Makers.
- Do not ignore Farming Level 8, since it is the unlock gate.
When to farm oil
A good oil setup starts once you have a steady slime supply, hardwood access, and enough gold to invest in artisan equipment. Early game players usually rely on corn or sunflower because those ingredients are easier to obtain, while late game players shift toward truffle oil for scale. The best results come from batching machines in a shed so multiple items can process at once.
Practical setup
The most efficient oil operation is usually a two-track farm system: crop inputs for convenience and pig truffles for money. That structure lets you keep a steady supply of regular oil while prioritizing the higher-value artisan product for selling. If you are optimizing your farm income, truffle oil should be treated as the premium line and regular oil as the support line.
In short, the definitive oil making guide is simple: unlock the Oil Maker at Farming Level 8, craft it with slime, hardwood, and a gold bar, and prioritize truffles whenever profit matters. Use sunflower when speed matters, corn when convenience matters, and truffles when gold matters most.
