To determine if gas in a can is bad, pay attention to its appearance, smell, and the length of time it's been stored. Bad gas often has a sour or stale smell, unlike fresh gas's typical pungent odor. Look for any discoloration or sediment. Gasoline that's been stored for more than 3-6 months, especially without a stabilizer, may have degraded. Using bad gas can lead to engine performance issues, so it's advisable to dispose of it properly if you suspect it's no longer good.
