All measurements (6 more)+
Lubricity Test Before Use
- 1two-stroke oil no specific brand named in the transcript
bearing scoring compared to 10W-30 conventional motor oil (from a previous video) was very close, with only a very slight amount of additional damage on the two-stroke oil
Cold Flow Test Setup
- 1two-stroke oil no specific brand named in the transcript
oil was placed in a freezer at -10 F alongside 10W-30 to compare flow at extreme cold; the transcript describes setting up this comparison but does not state the actual result
Engine Run Test
- 1two-stroke oil no specific brand named in the transcript
ran a small 4-stroke engine for a solid hour, partly under load via an engine brake; engine ran fine, described as maybe a little hot, with some blow-by which the host attributes to the test engine already being worn out rather than to the oil
Compression Test
- 1two-stroke oil no specific brand named in the transcript100 PSI
before and after, no change (per video chapter titled 'Compression test: 100 PSI (no change)')
Lubricity Test After Use
- 1two-stroke oil no specific brand named in the transcript
bearing scoring for the used two-stroke oil was indistinguishable from both new two-stroke oil and 10W-30, described as 'just as good or very close to being just as good used as it is new'
Contamination Check
- 1two-stroke oil no specific brand named in the transcript
oil was thinned with acetone and filtered through paper towels; no visible metal contamination (no chunks of steel or aluminum) was found
How it was tested
- lubricity / wear-scar test before use (vs 10W-30 baseline)
- cold oil flow test at -10 F (setup described, result not stated in transcript)
- 1-hour engine run test under intermittent load
- compression test before and after
- lubricity / wear-scar test after 1 hour of use
- oil filtration check for metal contamination
Data notes and caveats
Single-product myth test of whether 2-stroke oil can substitute as 4-stroke crankcase oil, not a head-to-head comparison, so isHeadToHead is false and there is no winner, runnerUp, or budgetPick (there is nothing else in products[] for it to have won against). Host's spoken verdict: 'Two-stroke oil in a four-stroke engine, I'm really surprised at how well that worked,' with no compression loss, comparable before/after lubricity test results, and no visible metal contamination when filtered, though he explicitly warns viewers not to actually try this in their own engines.
