|---|---|---|---|---|---|---|---|---|---|
| 1MotorKote | only up to about 1 percent of the contents are disclosed on the SDS; flashpoint listed as over 200 F with no maximum given; boiling point not tested; most disclosed ingredients, per the narrator's own CAS number lookup, appear to be antioxidants | compared to a 10w30 baseline bearing on the narrator's own lubricity tester, the MotorKote treated bearing showed a very very small amount of scoring, described as very impressive | MotorKote coated race and bearing soaked in water, then run for 30 seconds again; some additional damage or scoring appeared but described as very minor | 1.5 oz of MotorKote mixed into 16 oz of 10w30 (the maximum label recommended ratio) versus plain 10w30; the blended oil noticeably increased film strength on the lubricity tester versus plain 10w30, though the mixture also turned foggy and changed color, cause not identified by the narrator | meta chapter states RPM range: 3,366 to 3,420; the transcript sets up this as a fixed-throttle baseline test (expecting RPM to rise slightly if MotorKote reduces friction) but never speaks the actual before versus after RPM figures, so it is unclear from the transcript alone which end of the range is the plain oil baseline versus the MotorKote treated run | engine pre-treated with a 50/50 MotorKote and 10w30 mix, then drained and refilled with plain water in the crankcase; the engine survived the intended test duration, needing water topped off a couple times as it flashed off from heat; cylinder wall inspected afterward as fairly dry but with a very slight MotorKote coating still perceptible | meta chapter states Compression test: 105 PSI (no change); narrator's own words are the compression test remains solid, consistent with the no change reading, but the 105 PSI figure itself is never spoken | meta chapter titled Normal engine temperature; narrator states the engine was not overheating with water in the crankcase, but no specific temperature figure is spoken | crankcase contents run through 3 successive filters due to sludge thickness; filter 1 showed little metal, mostly dirt; filter 2 showed a very small, very fine amount of metal; filter 3, from the bottom of the container, again showed little metal, indicating minimal internal engine wear during the water only hour |
How it was tested
- safety data sheet composition and thermal property review
- lubricity/wear scar test at full strength versus a 10w30 baseline
- lubricity/wear scar retest after a water soak, to test the manufacturer's water will not wash it away claim
- film strength comparison of a MotorKote and 10w30 oil blend versus plain 10w30
- engine RPM baseline test at a fixed throttle setting
- one hour engine run test with the crankcase pre-treated with MotorKote and 10w30, then refilled with plain water only
- compression test after the water in crankcase run
- post test filtration of drained crankcase contents to check for metal wear contamination
Data notes and caveats
Single product myth/claims test, not a multi-brand shootout, so winner and verdictQuote are left null rather than forced; MotorKote is not being compared against a named competing brand, only against a plain 10w30 oil control. Narrator explicitly states he is not sponsored by MotorKote or any additive manufacturer. Several numeric readings (RPM range, compression PSI, engine temperature) exist only in meta chapter titles and are not spoken in the transcript audio, though the qualitative narration (compression remains solid, engine not overheating) is consistent with those chapter figures; logged to data/onscreen-only.txt for frame-level confirmation. Overall the video's conclusion is a rare unambiguously positive result for an additive-type product in this channel's typically skeptical additive test series: both of MotorKote's core claims (reduces internal friction, water resistant bonding) appeared to hold up under the tests performed.
