Your set up is the best in my opinion. You don't touch it while the test is going on and you always clean it before moving on to the next test. Keep doing what you're doing. 👍👍
Thank you!
I agree, simple and straight forward with standardized method for testing. Seems fair towards the products being tested.
Agreed!
I second that Todd, excellent video!
It's also easily repeatable by anyone who cares to build this set up. The hallmark of a good experiment is one that is able to be consistently repeated.
I can’t believe anyone would ever question your authenticity. Or that you would misconstrue results of a test.
Thank you
Timothy Midkiff he is definitely excellent in his testing methods. I was just blown away by the results of a complete BG Professional Fuel System cleaning kit. I'd appreciate your feedback on it.
Timothy Midkiff
No question about the authenticity but the results can always have a slight variance. The main thing I like is that he always tries to limit the variables as much as possible under the "home shop" conditions. No million dollar lab here to get results that don't mean much to the guy using it.
Seems like a pretty fair test with a home built machine.
Like the videos. Thanks for the uploads.
Thank you!
Ah! So you built your own Falex friction tester! Ok, so to get more technical, the Falex uses a compound rounded wheel, much like the one you have on the weight arm. You can get those kind of bearing races from an implement parts house. That gets you an even better (smaller) surface area. (1970's New Holland balers use them) The wheel is supposed to run in an oil bath. Just make a cup for it to pick the oil up from. (If it slings oil, your speed is too fast...) The roller would be placed perpendicular to the wheel. With the compound curve of the wheel and the roller cross-wise, you get a very small contact pattern. The pressure term you're looking for is PSI. When you have 10 pounds applied to 1/100th square inch, you have 1000 PSI.
A Falex would also have an Ammeter. As you stack weights on the weight arm you can watch the amperage draw increase up until it stops the machine.
Always base test your oils at what would be operating temperature. Hence the reason for the oil bath. You can monitor the bath temp to get a better idea of the actual film strength in working conditions.
I haven't run a Falex in 30 years! They were sure a lot of fun, though! Royal Purple came out on top, and Pennzoil on the bottom! You'll be doing LOTS of comparisons, such as mineral to sythetic, low vis to high vis and then, of course, wonder drugs. WHICH, by the way, you'll be simply amazed at what Prolong straight out of the bottle will do. THAT'S where the danger begins, because you can't run straight Prolong in an engine! Well, YOU could! after all, it's what you do! So while you're getting your education, educate yourself as to what is in the additives, how that additive prevents metal-to-metal contact, and what adverse effects that additive might have on the rest of the additive package in the oil itself.
You'll be on this for a while! Speaking of which, you'll be smoothing that wheel for a looooooong time if you're going to use 1200.
Great job on the build!
Addendum. Plain "mineral oil" from the drugstore could be considered base stock. It's the additives that make "motor oil" what it is. Plus, dynamic friction and static friction can be tested. If it's running, you're testing dynamic friction. if, during your test you turn the machine of and then back on again, you're testing static friction.
Friction reduction alone does not make a good oil, by the way
I really enjoyed reading your comments. You are very knowledgeable on this topic!
ElderlyIron
And I bet that Falix gizmo would be only a couple of bucks more than the farm boy's homebrew, and almost as good, test setup. LOL Good enough for the rest of us, I think.
"Royal Purple came out on top, and Pennzoil on the bottom"
Of course you didn't post the rest of the list!
muinaiset that didn’t take long lol.
Your scientific methods are well thought out. I'd bet your background is engineering. Don't laugh... But how about using that machine to test "personal lubricants". I'd like to know which one is best.
lol. Thanks for the video idea!
Project Farm do it! Sister is a saleswoman for pure romance so some unsponsored science to show people may help her with her sales!
How about a synthetic oil vs. non-synthetic test?
They say the more expensive synthetic oils are better for your car than plain oil.
But is that true?
How about the lubricity test and the engine seize test, normal vs. synthetic.
How about Mobile 1 Synthetic vs. standard non-synthetic?
Great video idea!
good idea, but i wonder if the synthetic holds up better over a time span,, oil that has done a few thousand miles, and has its share of contaminates, and also maintains its viscosity better, it may not show up as better new vs new
Jusb1066 synthetic has less thermal breakdown, hence the longer lifespan. You are correct new vs new will not show much of a difference, however even when new a good synthetic is the superior oil do to molecular size and uniformity. Is it worth the extra cost? I don't think so, at least in the old engines I run (all 3 vehicles I drive regularly are from the 90s)
@jay it may indeed be your older engines, modern engines are more stressed, run hotter, even smaller passage ways, cars used to use 20-50 now my little car wants 5w30 synthetic which is what sports cars used to want.
Project Farm
If you do that, throw in a semi-synthetic also, please. Thanks, love the vids❗
What about baby oil as a engine oil substitute?
Great video idea
Tyler Eifert watch lifeod video
th-cam.com/video/7kUoeWOl3Sg/w-d-xo.html
Not bad, but I'd like to see a little more scientific approach.
I suspect the results will be pretty bad but might be a fun video anyhow lol
consistency is the key and you have that with you test.👍
Thank you!
You should test traditional animal fats that were used on the first steam engines and locomotives, versus modern petroleum-based lubricants.
Great video idea.
whale oil! lol dunno if you can find it, lard was a good lubricant actually (but the heat makes it too thin)
Yeah, I trust your method alot more. AND it's been proven to help me man... there are trolls everywhere. Don't worry about them. From now on I'll just comment what recently has helped me. I think you need to know what you're doing to help us, not what you're actually doing right...that others don't agree with lol
Thank you very much!
I would like to see a test of new 10-30 vs used 10w30 and also new 5w 30 vs the 0-20 that most new cars use
Great video idea!
N1ck0145 Garage fantastic idea!
I want to see Delo CJ-4/SN 5W40 v.s. Castrol Edge SN 5W40
The test would have to be done in varying temperatures to be a fair comparison. Because 5w-30 and 10w-30 oil are the same viscosity when hot.
evilution that's not true at all. 30 is the viscosity when the oil is in a hot engine. The lower number is the viscosity when cold.
Twice the uploads, twice the knowledge! Your approach to these tests is thorough and methodical.
Thank you very much!
This tool seems extremely simple but consistent at measuring the effectiveness of fluids to lubricate a high pressure point of contact between a moving part and a stationary part. Apparently that's how other similar devices function as well. That said, does this happen anywhere in a properly operating machine? That is, does a lubricity test actually tell us something useful? The fluids' behaviors under high pressure and this particular movement scenario don't necessarily correspond to how they operate in a normal engine.
Again, no complaints about the tool, and I realize that lubricity isn't a test you invented. I'm just wondering how meaningful it is.
Great point. Flat tappet engines would be somewhat similar to this test. With that said, film strength is pretty important in my opinion.

A double upload!
Sunday special!
Justin Y. Dude ive never seen you in any comment section
The Master Commenter maybe he changed his name? I want to to something cool and easier to remember than my hard to spell last name.
Aniquin does this guy have a bad reputation? He seemed cool in this comment. Only you are being cruel at the moment. Be kind. Please rewind seems to apply. Edit or delete your comment if you have deceny.
Aniquin Im pretty sure he actually watches the videos. I've seen him on almost every project farm video and alot of videos about cars. He doesnt do it on purpose
Quick question for you, you did that seafoam episode, if I remember you put it in fuel tank and crank case and also in the intake? I’m doing a 01 F350 7.3 diesel build on my channel and I was going to seafoam into the gas tank, fuel bowl, and crankcase, but I don’t think I’ll use it in the Intake because the spray version says “not for diesels” any thoughts on why? Is it not oil based? Maybe if I put liquid seafoam into a spray bottle and spray into the intake?
Great point. Adding Seafoam to the intake could cause engine damage as a result of the engine revving up beyond redline RPM.
I just love to watch your videos and you have helped me with some choices for different products that I may not have made previously. As a driver, I see a lot of Motorkote being pushed to Owner Operators. When I saw your water test a few months ago, I was pretty excited to see that they were on your radar. Could you do more tests on MotorKote so that I can see if it is as good as it says for lubricity and I'm curious how long it would last without oil/Motorkote mix in the crankcase. Keep up the great work and I'll definitely keep watching!!
Thank you very much! I'd like to do some long-term testing with it to see if the film strength holds up.
Can an engine run on %100 gas line antifreeze? We use it regularly up north in our snowmobiles.
Great video idea
Test Walmart brand full synthetic oil
Thanks for the recommendation
This video is mind numbing, but I am also quite mechanically inclined. I think you did a good job explaining it to the back of the class though.
I know your lubricity tester is a hodgepodge mess of parts cobbled together to build this rig, but at the same time I have never had a complaint.
One test from it shows nothing, but accounting for all previous tests sure paints a good baseline to compare to and therefore accurately represents one product versus another.
I didn't like the idea of sanding the race every time at first, but if done consistently, it truly gives every test a fair playing field. I think doing it that way is truly the best way with the setup you have going.
I'm not sure who has been giving you guff about the test rig, but I for one think that it is the most accurate way to do it without just pissing away money on lab quality tools.
Thank you for all the tests, I think they are fun to watch and make for some good information in regards to "I wonder" type topics, even if what we find out is useless information in the end. Lol
All great points and thanks for the positive comments!
Thank you for showing and explaining your tester. I, like you, feel this mechanism will give a much more accurate out come. 👍🏻👍🏻
Thank you!
I'm looking for the test between motorkote vs dura lube that was a great test do you still have it up? Thanks for all your product testing imho your word is gospel and a huge part of how a chose products thanks!! 💯💯💯
Thank you. Both videos are still available.
you should try a live steam and having us pick what you do for the day with some random materials you lay out and check results. it would also be a good time for you to gain some donations through youtube. just an idea
Thanks for the recommendation!
Does 87 octane gas lubricate better than E85? Had a argument that e85 will wear out your engine faster.
Seems like a great video idea. Thank you
Speaking of lubricity testing, see how well premium brands like royal purple vs mobil1, castor, penzoil, gtx etc, and maybe if theres time, mobil conventional and mobil synthetic, difference in lubricity in extreme heat and very low temps (like a cold start)
Great video idea!
Good work keep it up, DIY tubers are my favs, you get all sorts of different ideas from different people and we all grow together, keep it up bro!!
Thank you very much!
Try to lubricity test soap
Great recommendation.
Project Farm go-jo, lava, orange, goop, thank you
Your test is the most accurate, good explanation to.
Love the double upload, keep up the good work 👍
Thank you very much!
TEST IT FOR 5 MIN
Thanks for the recommendation.
I remember back in the late 80s and early 90s there was a guy who sold Justice Brother's products. He drove around in a van with a similar device showing off how well his lubricants worked versus the competition. Anyway..... his testing device looked very similar to yours, you must have copied a commercially produced test rig to make your own? Keep up the good work!
yes he did copy the basic design, but as he mentioned 'some' test using a hand pressure, which as we know can be used to lie to you, a set weight and hands free is consistent as project farm isnt selling you a product
Thank you
Can I pay you to do oil several oil additive testing? you also can post video online young our product. Please let me know.
It would be great if you could test diesel 15x40 oils for lubrisity like delvac, mobile, supertech, the ones from walmart that would really be nice for truck drivers!!!
Oh yeah 😎. How does one or Project Farm make vegetable oils work in Diesel Engines? Timing changes? Different or same injectors?
I have posted this on 2 will this destroy an engine videos, but they were kind of old it is a twist on sugar in the tank.
How about a mixture of thick syrup which would have a lower water content (like a table syrup), molasses or honey and alcohol (90% or higher ethanol or isopropanol) to try to kill an engine, I have always thought that this would mix with the gasoline unlike sugar and make it in to the cylinder to carbon up the engine and cause problems.
Why do you run the test longer than 30 seconds in some videos? there is one video where you run it for 10 minutes.
Engine din't have EP (extreme press) friction like gears or transmisions. Now try with the cheaper transmision oil and see the results. Uselees machine.
Can you test 3m VHB double sided tape? It is supposed to be rather extreme in its ability to stick or bond with the surfaces.
Well man, Heads up! Lol Just noticed that Farm Truck and Azn from "Street Outlaws" has posted how cool your videos are on their Facebook page!!! You may have a few more subscribers buddy!!! I've been here for a long time lol it's going to be good! Everyone will love your channel!! Congrats man!!!
Thank you very much!
Would it be acceptable to add more weight to the arm during the test. Most machines I have seen have one pound weights that you can add as you do the test to show the difference between oils and oils with additives
I've got a Honda and I think my EGR passageways may be clogged after 160K miles. I'm car handy, but cleaning them out is a real pain because you have to take out the intake manifold. I'm looking for any kind of product that can be sucked, soaked, or something into the car and help clean those out without taking apart anything. Maybe you could test cleaners and see how well they do getting sucked up into things without having any access to physically breaking the carbon apart.
Great video idea
This may sound inappropriate or weird, but I’ve gotten high and wondered if an engine would survive using “personal lubricants” instead of oil. Not exactly sure how well they’d work under extreme heat. But I’d find that interesting and funny at the same time. 😂
Thanks for the video idea
Can you try Amsoil synthetic motor oil for wear vs other fake synthetic motor oils, Thanks for the great videos...
Great video idea
It is sad that people will try to sway the results. Ahem. Russia. All jokes aside you really thought this test out very well. Only thing I can think of though is in an actual system, your parts are likely going to be fully surrounded in oil. In this setup the oil gets flung around and not entirely contained in the cup. There may not be a huge difference, but it’s something I’ve though about while watching you use this. Thanks for sharing :)
Thanks for the constructive feedback!
:56 Safe to say you were never a professional welder......Even ugly welds can do an amazing job though.
lol. Not a pretty weld at all. Thanks
I'm actually a PhD scientist and I really appreciate your consistency in testing. Sir, you are a scientist. One thing I'd like to point out is, it would be ideal to run the test at least 3 times in order to have a concrete result.. it's part of GLP
Thank you for the positive comments! Great point on 3 tests.
The pool pump motor repair guy approved ! that was good info.. farm man
Also, why is it you had Prolong on the shelf but never tested any of their products? I have shared my experiences with their products and would like to see them go head to head with other products.
I plan to test it in the future.
Please test different weight oils, like 80w90(gearbox oils), and different engine oils, use same brand, really don't care about the brand, but how the different oils behave in reality...
Like straight 30, 10w30,5w30,5w40, 0w40 and gearbox oils like 80w90. More how different weight oils behave, not the brands. As some recommends only straight oils in there engines.
If don't want to, I'll do it my self as curious.
Great recommendation.
Hello Sir! I am a big fan of your stuff! I think it would be awesome if you could do this lubricity test with 3 of the "hottest" engine oil additives on the market right now. #1 Archoil 9100, #2 Turbo Maxx, and #3 Xtreme Green Engine Life Treatment. The lubricity test I saw on TH-cam using the Xtreme Green is almost impossible for me to believe. I would love to see you "myth-bust" these products! Thanks for listening...
Thanks for the video idea.
Try Extralube ZX1 on your lubricity tester. C60 Nano-Carbon Buckyballs are supposedly the secret sauce in this lube...
www.team-zx1.com/c60-micro-lube-trigger-spray.html
Great recommendation!
You've basically built a Timken-Test machine. Not ideal for testing oils as it was originally used for testing bearing greases (because you know: it tests bearings.) In your method it provides good empirical data on lubricity of oils, which in this context is just what you need. There is a reason the Timken-Test is not used by any SAE/ACEA/JASOL bodies for engine oils.
Would be great to see you test some greases ;)
Thank you

Thank you very much!
Very well-made video. Now I understand what you're talking about in your other videos.
Thank you!
Do u ever change the wheel race ? As it would eventually get a groove in it !
Bravo on the build, looks great. I think it'd be quite interesting to see some diesel fuel tests: US diesel fuel vs. high sulphur diesel (if you can get it) would be super cool to get a baseline on lost lubricity. Then lots of people add 0.5% 2stroke oil to diesel, would be interesting to see what this does, especially as a comparison. Personally I'd be curious about adding 0.5% high sulphur gear oil as well as the losses from 20% water emulsion (which is a reasonably popular trick for improving diesel engine efficiency).. Keep up the good work!
Thank you
Yes please test some oil. I'd really like to see some comparisons between 0W30 or 5W30 and 0W40 or 5W40 especially with varying temperature.
I really would like to see if a 0W30 has any advantage over a 0W40 - putting efficiency aside.
I recently bought a new car with some 30 000 kilometers longlife oil in it. It is 5W30. I thought about changing it to the best 0W40 Oil I can get - which I believe is from mobil 1. I compared manufacturers specifications which each brand of oil meets - and mobil 1 full fills the most and strictest requirements.
A mechanic told me I could not use 0W oils because they're too thin. Is that true?
As far as I understood oil lubricities a 0W30 is thinner a low temperatures than 5W30 but at operating temperature they behave the same. A 0W40 should offer a even better film strength at operating temperature as 0W30 or 5W30 which should result in lower stress on the engine.
He said I could use 5W40 - but why would I? Cold starting the engine, especially in Winter - a 0W oil should spread around and lubricate all parts a bit faster then a higher viscosity oil.
He also mentioned that race cars would use 10W60 or even higher - what I already knew. I always thought the need for higher film strength will ultimately result in the oil being thicker at low temperatures. Ideally they would also want to use a 0W60 or higher oil, if it would be physically possible to create an oil with that characteristics.
The only circumstance a engine can suffer damage from too thin oil would be if you would put a 0W20 oil in an engine which was designed for 0W30/40. I will be fine until it reaches operating temperature. At high stress the film will break down and metal will come into contact with metal.
Whose reasoning is right? My central thesis is a 0W oil while being cold is always thicker than any other oil at operating temperatures.
Is this where my reasoning is flawed, or am I right and the mechanic didn't knew what he was talking about?
You bring up excellent points regarding the cold and hot viscosity of oil. Personally, I don't believe any harm would occur for the reasons you've mentioned. If under warranty, I'd likely continue to use the recommendation viscosity. Otherwise, I'd go with what I thought would work best. Hope this helps.
Have you tested two stroke gas mix with it? Using different two stroke oils. Or two stroke oil gas mix in the oil pan in a 4 stroke?
Not yet. Thanks for the recommendation.
Wonder what Prof John Kelly from Weber University would say about this test?
Thanks for watching.
I've been searching and asking, and cant seem to find an oil test on your page. Where you test the top synthetic oils.
Royal purple HPS, amsoil, redline, Mobil 1,Castrol, valvoline, pennzoil etc. Will you pleeeease do one!? Like lubricity and flow and cleaning etc
Thank you! I've just begun testing oil brands.
Can you test different engine oil brands to see which one is better/more relevant to his
declared characteristics? For example Bardahl XTC C60 (Fullerene + Polarplus). There are always very discordant opinions about the same oil, it would be interesting to see which one lasts longer, which one resists better to heat, which one leaves less sludge, etc...
Thank you for your high quality, ad free contents.
Great video idea! Thank you
Hey!
Just a simple, cheap, but I think very popular video idea: regular vs premium petrol.
Is it any better, will it create less wear/carbon, etc.
Please test more than one type of petrol/diesel (if you have diesel engines at all).
Thank you!
Great video ideas--thank you
Can you test racing oils on this tester? Valvoline, Redline, Joe Gibbs, etc with a 20w-50 weight? With and/or without zinc - like additives? Thanks a bunch!
Great video idea!
What about when they use a torque wrench? And actually try to apply enough force to stop the motor. Will you be able to duplicate that?
The use of a torque wrench is still an "one arm bandit" approach that provides less accurate results than this setup.
Hey Bro, Good On Ya! So I am curious if you have ever tested the claims of the oil additive "Power Punch" ? I have been using it for years, to pre-lube bearing surfaces, while assembling engines. I also like to add a bit to the engine oil of high mileage engines, as a measure of extending it's life a bit. I've never had the opportunity to do the extensive type of testing that You do, so was thinking it may make for a cool episode. What do ya think mate?
Not yet. Thanks for the recommendation.
I would LOVE for you to test oil filters and stick this Frantz Filter thing in the mix. I actually saw it in my TH-cam "Up next" column while watching one of your vids and have questions as to whether it really works. This is the vid I saw if you want to check it out. th-cam.com/video/Jn5yLW7efK0/w-d-xo.html But oil filters would be a great episode because I never know what is inside the casing and if it is actually worth the money I am paying. I bought a Wix oil filter when I went to O'Reilly to get the Motorkote but no idea if it is any better than the MicroGard that was a dollar less.
Thank you for the recommendation to test oil filters. I'll check out the video on Frantz filters.
I've got a cracked engine block and I've been looking for something to patch it with. It looks like jb weld will be what I use but I've saw belzona 1111 come up a few times in my research. Could you do a video testing this product?
Thanks for the recommendation.
I left a comment a few months ago about what additives to add to a 212 predator engine for an endurance karting league I'm running in. I took Project Farms advice and added Motorkote along with Amsoil 4t racing oil, changed the oil after every race weekend and maintained this engine to a T. After weekends of hard racing and over 55 race hours on the engine I am happy to report that she is still running strong although there have been a few hiccups. During our 8 hour endurance race for some unknown reason at hour 7 we all of a sudden lost power to the engine, we completed the race took the kart home and never have had the problem again. Other than that shes been flawless, the durability has really surprised me, at the first race weekend we were hitting a max of 5342rpm on the straights and after 55 hours she was still pulling to 5290. Of the 14 karts that committed to a full season 11 are still running with the original 212 they started with. We had one failure due to loss of oil and the other 2 were changed because for 2 hours they had a small oil leak (Teams fault not the engine) and they wanted to be safe and not sorry. Overall I am very impressed with this $99 harbor freight engine and how its performed thus far. We have 2 more 4 hour events and a 24hr race to wrap up the year, that will be the true test of this engine since the longest its run before is 8hrs. Cant wait to tear into this thing at the end of the year!
Connor, Thank you very much for the update on MotorKote and Amsoil. The combined film strength of those 2 products is perfect for the "extreme performance" needed in racing. Thanks again and hope you have a great final 2 races.
But what about the fact that with other lubricants they were able to stop the motor but once certain lubricants were added they could not stop the motor no matter how much preasure was applied?
All great points.
Apparently, Amazon Basics has an engine oil. I'd love to see a comparison with your setup against mobil 1 and others. TH-cam Scotty Kilmer did a video where he did some good research, but no testing. Love all your videos!
Thank you for the video idea!
Test 20w-50 v-twin oils PLEASE! Harley, Harley synthetic, Amsoil, and royal purple. Every Harley owner will love you for this test.
Thanks for the video idea!
From thinking about the physics it should not make much difference, I would estimate > 0.1%, but may be worth a test to rule it out. The position of the Bearing in the lubricity tester, just in, in fully not straight, to the left, to the right. Just a potential source of error. By the way I love your content and you have a great understanding and control of variables. Please keep up the great work.
Great point. Thank you!
I'd like to see a test done with different bearing pressures to try to demonstrate that oils with high film strength only perform differently under extreme conditions (under lower pressure conditions the wear should be the same, then under higher pressure the more expensive oil should perform better).
Maybe compare something like regular cheap oil, AMSOIL Dominator or similar, and cheap oil with a high-zinc break-in additive, with each oil being tested at three different bearing pressures.
This is a great recommendation!
Your method has always been fair. Equal treatment for every product. Can't see why anybody would complain. The whole idea is to have a standard that is not only repeatable, but cuts as many variables out of the experiment as possible. Whether it's 5lbs of force are 105lbs of force, as long as it is always the same between and within the acceptable limits of the products tested, it's a valid test.
Thank you very much!
The bearing race should be smooth as possible, If any oil additive has a solid, it will adhere to the asperity's in the bearing. You will not be as constant. Modern engines can reach as high on parts up to 200,000 psi Check the API guide.
Thanks for the constructive feedback
While it may not be quite a "lab-quality set-up", for someone that does video out of his garage, I think it's quite valid. Keep up the good (and entertaining!) work!
Thank you!
Can you test using diesel oil such as Rotella or Delo 30 wt in a small engine as apposed to the typical SAE 30? Alot of people are recommending this but I'm curious to see if it's actually superior, does it actually prevent wear better due to its heavy duty additives? Thanks for all of the great videos.
Great video idea. Thank you!
I've got a video idea for you how about to see just how long the oil lasts and also to see if it really does what it advertises for instance Mobil 1 extended performance states that you can go 15,000 miles between changes and Mobil 1 annual performance stage that you can go 1 year or 20000 miles whichever comes first between changes I'd like to know if that's true and if you ever tried what does it look like?
Thanks for the video idea!
Dis you make this device? You should do a video on how you made it unless you have one.
Thank you. Yes, I did make this test. I should have created a video on making it.
I have a question for you. I've been trying to figure this out for 20 years. Higher viscosity oil equals less flow higher pressure. Lower viscosity equals less pressure more flow. Which one causes more engine damage. In my mind I would rather have better flow less pressure. I assume higher pressure with less flow equals more bearing damage. Never able to figure it out.
This is a great question and there are lots of opinions on this. My opinion is that the viscosity should be adequate to reach optimal oil pressure. Issues arise from too much or too little pressure. Just my opinion. Thanks again.
Your description of the testing device is similar to the "Experimental" portion of a technical publication, with the exception that your description is accurate. Much of the work (a minority, but a significant minority) provide misleading or incomplete information on their experimental procedure. If you do a search on "reproducibility in science" you'll be amazed at how bad it is. That extends to the patent literature, too, where there is supposedly complete disclosure of a process and often there is nothing of the sort. What I'm getting at is that your being honest while a lot of scientists and engineers are not.
Thank you very much for the positive comments!
Would love to see ampere meter attached to this setup. Sometimes it is hard to see difference on bearings. Maybe ampere meter would show something more?
Also, can You test product windigo (seems like there is windigo oil and windigo additive)? Videos on their sellers web pages seems fake, practically no bearing damage.
Great recommendation. Thank you
Who could possibly give this man and his videos a thumbs down? The 27 haters out there that were to lazy to do it them selves. On another note. Sir could you please do a series of videos on the Klotz products? I think it would be a huge success. But mainly because I am partial to the products and I want to see them against the competition. Who knows may even change my mind on a few thinks. Thanks for the consideration.
Thanks for the video idea.
Hi, how about testing degreasers? Citrus, spray9, simplegreen , krud kutter, goo gone, zep, gunk. Thanks for the great channel!
Great video idea!
What would the result of this Lubricity test be without any lubrication at all? Your baseline is always 10w30; perhaps a baseline of purely bearing to raceway would also be a fantastic comparison baseline. Great Videos!
That would cause a lot of damage for sure. Thank you!
Test some gear oil with it, weather synthetic, mineral, hypoid 75w, 90w, 140w, etc. Then straight gear oil vs mix with additive.
Thanks for the recommendation.
Todd, excellent video of your Lubricity tester. Now I understand the basics of how the test works. Thanks for the double upload :) always have enjoyed your videos :)
Josh, Thank you very much!
Can we get a series of not necessarily traditionally used lubricants? Bacon grease? Lard? coconut oil? Butter? water? gasoline? Or maybe non fluid (at room temp) lubricants like lithium grease or moly? A spreadsheet of non standard substances tested on your machine seems like fun.
Great video idea!
Do you replace the race at all? Just wondering if it would wear enough to affect the circumference over time. Wouldn't really matter comparing results performed one after another much but it's nice to compare results from different videos. Obviously the bearing takes the bulk of the wear but I'd imagine the race does wear somewhat
I don't use it enough for it to need replaced yet, but I have plenty of them to use when it comes time.
Don't know if you possess an engineering degree , but , you are one savvy fellow . Perhaps it comes from the Missouri, show me water ? Love your attitude and videos . Keep up the good work. Thank you for your effort.
lol. Thank you very much!
What I really like about your lubricity testing machine, is it helps remove your subconscious bias. Even if you want to be neutral, a subconscious bias will affect how hard you press on the arm without you knowing it. For example, a person operating a traditional testing machine my press harder on a cheap lubricant verses an expensive lubricant. To take the test one step further, you should remove your ability to know which lubricant is being tested until after you have the results.
Great point and great recommendation. Thank you
Love your channel. Could you please check the film strength of synthetic 5w20 with Lucas engine oil stabilizer mixed in?
Thanks for the recommendation.
I’d be interested to see how a new vs 3000 vs 5000-10000 mile oil comparison played out. To keep it legitimate you’d have to use the same vehicle to wear the oil. Not sure how that work out on your side. Might not want to push your own personal vehicle that far
Thank you for the video idea!
Hi. I was telling my friend about your videos and he said lubricity at room temp made no sense. Why don't you combine the cooking and the lubricity testing to replicate actual use conditions better? Thanks!
Thanks for the feedback.
That doesn't really do anything, its not under pressure, i wish i could see a pump push out idk? 29psi to a thin film of oil through a metal to metal contact plain bearing like engine bearings w/ a glass/acrylic panel to see it in action. :D
All that machine shows isn't really much. I want to see real results on how oil is properly used not just thrown and rubs on something.
Thanks for commenting on this.
I read somewhere that adding water to the oil would create less scoring on a lubricity tester. Have you tried this? Then again, the guys at amsoil claim that head and shoulders works better than most oil additives on the rig, (as I'm sure you know) and you proved that was BS. Thanks for that.
Thank you!
The only problem I have with your configuration is the way that the wheel race picks up oil from the plastic cup. If the cup is a little more or less full, the wheel race can pick up more or less oil which would influence the size of the oil wedge between the bearing and the oil wedge and so your results. Maybe a positive displacement pump attached to the same motor (for consistency) that drops oil on top of the race just after the bearing/race contact point? Have you tested your lubricity tester with the same oil at 2 very different levels?
Thanks for the constructive feedback.
Did you jam your poor thumb ? I've just grown out a good bruise under mine from months ago.
Thumbs aside I think this test is awesome and it's probably the most accurate test of showing long term wear in a short amount of time. Keep up the good work and videos.
Thanks again! Yes, I dropped a PTO shaft on the thumb. Lots of pain!
Can you test Synthetic vs Dino oil of the same viscosity? Or have you done it previously?
Great test idea!
I have not seen the 2 stroke oil with diesel fuel libricity test!!! With different oil brands.
Thanks for the recommendation.
I don't know why but I love this machine, it's so simple yet provides a great visual result. I cheer a little when you test a liquid because I know this machine is likely to have an appearance. 👍
Thanks for sharing.
Not all is fair in love and lubricity on TH-cam, but you’ve done it right on every video I’ve seen and it’s always consistent and you even do it multiple times. It’s one of my favorite tests that you do! Just out of curiosity (as I know you have plenty of comments to sift through and a new video dropping today I believe), but what product was the messiest/most annoying to clean after doing this test? I always see it starts splashing everywhere and I figured I’d ask which one was unforgettably messy/difficult to clean up afterwards? Thanks again for all that you do!
