Motor oils also have an expiration date: Here's how long they can sit in the garage
Many people store various items in their garages that they rarely use, and among them is often motor oil bought in advance or on sale. However, the question arises as to how long it can stand before it becomes unusable...
TL;DR
- Motor oil generally has a shelf life of three to five years.
- Synthetic, semi-synthetic, and mineral oils have varying lifespans.
- Exposure to metals like iron or copper can accelerate oxidation.
- Opened oil should be used within six months.
- Store oil protected from sunlight and extreme temperatures.
- Extreme temperatures can affect lubrication quality and cause sediment formation.
- Check oil texture and color before use; it should remain consistent.
