The measured results
Every number below is read straight from the test. Products are listed in the order they finished.
All measurements (7 more)+
Tackiness/adhesion (disc pull test)
- 1MAG 1 Lithium Grease46 lb
of force to separate discs
- 2Conoco Pressure Lubricant Medium (vintage, circa 1940s)55.42 lb
of force to separate discs, the win in this test
Film strength / wear (lubricity tester)
- 1MAG 1 Lithium Grease
bearing showed noticeable wear damage, but far less than the vintage grease's bearing (described as the most damage seen on this test, referring to the Conoco sample)
- 2Conoco Pressure Lubricant Medium (vintage, circa 1940s)
the most bearing wear damage the narrator says he has seen on this test; described as not offering good wear protection
Corrosion resistance (24hr oxidizer test)
- 1MAG 1 Lithium Grease
described as doing very good preventing oxidation, called the best of the three (control bolt, Conoco bolt, MAG 1 bolt)
- 2Conoco Pressure Lubricant Medium (vintage, circa 1940s)
quite a bit of oxidation after 24 hours, especially around the base of the bolt; better than the ungreased control bolt but worse than the MAG 1 bolt
Cold temperature torque test
- 1MAG 1 Lithium Grease24.36 lb
of force to rotate the frozen bearing
- 2Conoco Pressure Lubricant Medium (vintage, circa 1940s)just over25 lb
of force to rotate the frozen bearing, nearly beating MAG 1's 24.36 lb but did not
Water spray-off test
- 1MAG 1 Lithium Grease
started at 214.22 g, ended at 212.26 g, loss of 1.96 g; crater approximately 67mm long by 41mm wide
- 2Conoco Pressure Lubricant Medium (vintage, circa 1940s)
started at 213.95 g, ended at 211.42 g, loss of 2.53 g; crater approximately 75mm long by 53mm wide, described as huge
Water immersion / rotation washout
- 1MAG 1 Lithium Grease
some grease washaway after submerged rotation, but retained noticeably more than the vintage grease
- 2Conoco Pressure Lubricant Medium (vintage, circa 1940s)
washed away noticeably more than MAG 1 after submerged rotation
Heat tolerance (dropping point slide test)
- 1MAG 1 Lithium Grease
held up under direct burner heat until roughly 400F before starting to liquefy and slide; packaging claims a dropping point over 500F
- 2Conoco Pressure Lubricant Medium (vintage, circa 1940s)
first to liquefy and go up in smoke, at approximately 200F; no dropping point information was printed on the original packaging
How it was tested
- tackiness/adhesive strength: two metal discs pulled apart, force to separate measured
- film strength / wear protection: lubricity tester, bearing wear scar compared visually
- corrosion resistance: aggressive oxidizer applied to wheel stud bolts (bare control, Conoco, MAG 1), checked after 24 hours
- cold temperature torque resistance: bearings packed and frozen at -20F for 24 hours, force to rotate measured
- water spray-off resistance: weight loss and crater size measured after water jet spray on a test plate
- water immersion / bearing rotation washout: bearings submerged and rotated, visually inspected for grease loss
- heat tolerance / dropping point: grease heated on a metal slide until it liquefies and smokes
- compatibility when the two greases are mixed together

Data notes and caveats
No chapters in metadata. Several non-brand phrases were garbled by auto-captions and resolved by context rather than taken at face value: 'kana coat' and 'eggwin' during the 30-second corrosion check almost certainly refer to the Conoco and MAG 1 greased bolts respectively (both were reported as fine at that point, no numeric distinction given, so not attributed to a specific brand's results); 'an advantage grease' in the cold-temp test is the vintage Conoco grease (confirmed by the just-over-25-lb figure matching the surrounding narrative); 'the fifties Greece' in the water spray-off test is also the vintage Conoco grease (confirmed because its stated starting weight of 213.95g exactly matches the weight given one sentence earlier for 'vendors Conoco,' itself a mangle of 'vintage Conoco'); the closing line 'Myra grease is definitely a whole lot better' likely means 'modern grease is definitely a whole lot better' (there is no third brand called Myra in this two-product test) but was not used as the verdictQuote given the ambiguity, in favor of a clean unambiguous quote from the cold-temp test. The compatibility test (mixing the two greases) found no separation issue and is not a competitive result. Only two products in this video, both purchased by the narrator, no prices mentioned for either.
