Distilling Stale Gasoline to Make it Usable Again
A recent experiment demonstrated the distillation of stale gasoline to make it usable again. The process involved adding aluminum oxide as a catalyst and heating the gasoline to separate usable components. While the experiment yielded some usable gasoline, safety concerns regarding the health risks of the process were highlighted.
- ▪Gasoline can become unusable due to oxidation over time, creating sludge.
- ▪The experiment involved distilling stale gasoline using aluminum oxide as a catalyst.
- ▪The process was conducted at various temperatures, ultimately collecting 880 mL of distillate.

Distilling Stale Gasoline To Make It Usable Again No comments by: Maya Posch June 3, 2026 Title: Copy Short Link: Copy Pouring the resulting distillate for testing. (Credit: Lowered Expectations, YouTube) The propensity of gasoline to ‘go stale’ through the process of oxidation is the reason why gasoline that has been stored for a long period of time is considered to be unusable, as it will no longer combust property. Since this process creates the sludge that you find in the bottom of an old gasoline canister, it follows that you may be able to distill out the still good gasoline. With this reasoning, [Joel] over at the [Lowered Expectations] channel set to work to try out this theory.
