The measured results
Every number below is read straight from the test. Products are listed in the order they finished.
All measurements (4 more)+
Fuel-injected generator under load
- 1Jet Fuel (Jet A / JP-8)
seemed to run better on jet fuel than on E10 gasoline
- 2Gasoline (E10)
ran acceptably but described as running less well than jet fuel in this specific test
Small carbureted engine (see-through cylinder head)
- 1Jet Fuel (Jet A / JP-8)
ran fairly good on jet fuel; carbon build-up on the cylinder head was not too bad, but there was quite a bit of carbon around the intake valve and down around the exhaust valve; engine was likely running a little lean because kerosene's viscosity is greater than gasoline and the carburetor is non-adjustable
- 2Gasoline (E10)not tested
Wankel rotary engine (on loan, run on RC racing fuel first)
- 1Jet Fuel (Jet A / JP-8)
engine survived running on jet fuel; goal was to spin it past 30,000 RPM but no confirmed achieved RPM figure is spoken in the transcript
- 2Gasoline (E10)not tested
Baseline runs (all engines)
- 2Gasoline (E10)
used as the baseline/control fuel before switching each engine to jet fuel
- 1Jet Fuel (Jet A / JP-8)not tested
How it was tested
- small carbureted engine (see-through cylinder head) run on jet fuel after a gasoline baseline, checking flame color, overheating, and power
- fuel-injected generator run on jet fuel vs E10 gasoline under an applied load
- Wankel rotary engine (borrowed from Warped Perception channel) run on jet fuel after first running on RC racing fuel, targeting over 30,000 RPM
Data notes and caveats
This is a fuel experiment/myth-test, not a branded product comparison: no competing brands, models, or prices are involved, so isHeadToHead is false and winner/runnerUp/budgetPick are null by design (per the spec's myth-test handling). All results are qualitative; the transcript never states a confirmed achieved RPM, compression, or other measured figure, only qualitative descriptions ('ran fairly good', 'better than E10'). The only clear verdict-style statement is a caution against long-term use of jet fuel in gasoline engines due to pre-ignition risk, which is captured in product notes rather than as a winner claim. Chapters (out of gasoline, new spark plug/headgasket, cold start on jet fuel, warm-up on gasoline, running great, running on straight jet fuel) align cleanly with the narrated sequence.
