distilling stale – A DIY experiment claims to distill stale gasoline using an improvised Vigreaux column setup, collecting 880 mL from 1 L and later using a second batch to run a car—while the process is presented as highly dangerous, with concerns about fumes, burn risk, and ex
The smell and the sludge are familiar to anyone who’s found an old gasoline canister after months—maybe years—and realized it’s not going anywhere. In this case. the experiment starts from the same stubborn question: if stale gasoline turns unusable because oxidation has changed what’s in the fuel. can you separate the still-good portion out again.
Joel. from the Lowered Expectations channel. set out to test that idea using a stockpile of “many grades of stale gasoline” he had access to through his job maintaining things like pressure washers. The first part of the demo shows how poorly these stale fuels burn before the effort shifts to the main distillation setup.
To the stale gasoline. aluminium oxide is added—both as a catalyst and to create nucleation sites intended to reduce the risk of “bumping. ” where a sudden surge can kick out of a heated flask. The setup is framed as a small-scale attempt to approximate what a refinery’s fractionating column does. but in practice the experiment is heating oxidized. contaminated gasoline rather than fresh crude fractions.
The dangers are immediate and. as the video makes clear through what’s missing rather than what’s shown. the concern isn’t subtle. There’s “incredibly dangerous” chemistry happening in the background. and the lack of PPE on Joel’s side is described as “somewhat worrying.” He does. however. ramp temperature slowly. looking for a workable sweet spot. The temperature at which the setup starts producing distillate is reported as beginning at 70°C in the flask. when the condenser began receiving its first load of “presumably clean-ish gasoline.”.
As distillation continues, Joel moves through temperature ranges to see what kinds of distillate he can collect. The work is described as being done with what looks like a Vigreaux column. The testing window extends “up to nearly 200°C” before the experiment wraps that batch.
In the end, 880 mL of distillate is collected from the initial 1 L. The various distillate fractions are combined for testing, but the video itself doesn’t show the actual testing process. Still. at the end of the video it’s mentioned that a second batch of the distillate was used to power his car—so the result is framed as working well enough to run.
That doesn’t make the outcome safe. The experiment is explicit that heating stale gasoline can generate many highly flammable and combustible substances. along with others that are “just downright bad for your health” to be exposed to. The piece ends with a blunt warning: “works” doesn’t mean safe. and the health effects—from short-term to long-term—should be obvious.
