Will Any Oil Work as Engine Oil?

[@Mariano.Bernacki]

Notes for V2: 1) You need a control engine with regular oil to be sure the chips are due to break-in. It is a reasonable assumption, but you do not know if the engines were producing the same, less, or more metal than expected. 2) Measure the quantity of oil you pour in and out of the engine to see if any oil was burning. Again, use a control engine with regular oil. 3) Consider extended testing, an engine that would be done in 50 hours and one that would last 500 hours might look about the same in the first hour of operation. Maybe the vegetable oil works great for 2 hours and then it breaks down catastrophically. Maybe the gear oil lasts longer than regular motor oil (doubtful, but you have not tested and so you do not know) 4) EGT/CHT probes and an Arduino for data logging.

When i was a teenager a bunch of us went camping in my buddies 78 dodge van and ended up putting a hole in the oil pan, hit a rock on it or something. But we were hours away from anything even with a running car. And this was before cell phones. Luckily my buddy had an odds and ends assortment of tools and random stuff. He ended up patching the hole with bondo and he mixed in some smashed up rocks to try to make it go farther and give it some structural integrity. We got that fixed when he realized we didn't have any oil lol. We had 2 quarts of atf and water and some booze. So it was either try our luck with the atf or run it dry. He took it easy and stopped loads of times to check on it but that van made it all the way to the closest gas station '2.5' hrs away where we got some oil and drained out the atf. He drove that van for years after that with no problems.

I sell castor seed for castor oil. Castor oil was used before petroleum in very early motor cars. The issue was a varnish over time, but the oil doesn't thin like other seed oils. British biplanes of WW1 used castor oil if I remember correctly. I'd love to see a test with castor oil!!

[@videodistro]

Castor oil is still used in 2 strike model engine fuel. You can get synthetic, but many people still.put in some castor for rust prevention properties. The castor, though, does create unwanted build up.

[@GGigabiteM]

Castor oil was only used in rotary engines in WWI. Rotary engines had a total loss oil system, where the castor oil, fuel and air was injected directly into the crank case and the centripetal force of the engine rotating would send it up induction tubes into the tops of the cylinders to be let in and burned. The exhaust was directly into the slipstream, no headers. An exception to those was the Gnome Monosoupape, which had ports in the bottom of the cylinder liner and used a complex push-pull rod to a valve at the top of the cylinder. It was used for both exhaust and air intake, while the fuel and castor oil came from inside the crank case through the ports. All mass production rotary engines were four stroke, even the Monosoupape. The reason castor oil was used is because it mixes well with gasoline, and maintained its lubricating properties inside the engine. Near the end of the war, Germany being on the brink of total economic collapse, they started to use a type of mineral oil called Votol. It was vastly inferior to castor oil and caused engines to seize up after just a few hours

[@gabet945]

​@@GGigabiteMThanks for the knowledge and history lesson quite interesting.

[@ManualM3]

Sometimes I’ll put Castor oil in my 2 stroke dirt bike and when I do that sweet smell coming from the exhaust brings back good memories from my youth. Such a distinctive smell. Good times.

[@GGigabiteM]

@@ManualM3 Don't inhale too much of the exhaust, or you'll have the same problem as WWI pilots, diarrhea. Since the rotary engines flung castor oil everywhere in a fine mist, pilots would inhale large amounts of castor oil and eventually it made it into their stomach. Castor oil being a great laxative would give them the runs.

[@mrturner69]

need to test under load, an engine can run for a surprisingly long time with no oil under no load

[@averyalexander2303]

Great point! I remember seeing ads for oils and snake oil additives where the oil and/or coolant was drained and the engine continued to run for hours, sometimes at high RPMs. I never saw one of those tests under an actual load though.

[@randyab9go188]

Slick 50 used to demo their snake oil in person with a little two horsepower Briggs & Stratton horizontal shaft engine. The end plate was removed and replaced with thick plexiglass I believe the British call it perspex. A ball bearing was installed in the plexiglass and that little engine was run over and over and over with regular motor oil, then drained, motor oil with slick 50 added, ran for 5 minutes and then they would run it for a half hour with no motor oil in it at all. Just like in this test there was no load on that little engine. That little engine survived through hundreds if not thousands of demonstrations. Sometime back I had a chance to buy one of those little engines used for the demo but the seller wanted way too much for it. It's a cool display piece but useless in its current state and if you put a new end piece on it it's like any other two horsepower Briggs. I passed.

Castrol make a vegetable oil called Castrol R. It was used a lot for racing up until the 1980s, when most turned to the modern better oils. I think all you have done is use these oils as a running-in oil, and maybe if you now used a multigrade, they will give much better results, with less contamination.

[@iwb316]

The name Castrol comes from the type of oil they used, which was vegetable oil obtained from the castor bean, it provided superior properties to that of the mineral based oils available at the time. When using castor based oils you should ensure the engine is thoroughly cleaned to be devoid of any mineral based oil, reaction between the two can lead to a loss of lubrication.

[@Herbybandit]

It also has a distinctive smell.

i dont think there was much cross-hatching on any of the cylinders and its surprising how badly scratched they were for a new engine. its true what they say, you get what you pay for. i bet the veg oil one if left running long enough would seize or blow, it would get too hot and not be as able to cope. interesting test though

[@1soupasaurus]

Quick reminder, while the vegetable oil worked in this case, that's because these engines don't have oil pumps. Had it been pumped it may have aerated and turned into a slimy mess.

I ran a VW Beetle on veg oil as a bet with a friend. He said it couldn't run 150 km (approx. 94 miles) on veg oil, and I said it could.

[@karlbeckmann8865]

Hey, i don't want to critisize too much. But... You should have broken in every single engine with regular oil, for 60 minutes at least. Then, you should have put in the other oil, and most likely you wouldn't see results for 6 hours. If you do it again, maybe try to put something together to put a load on the engine. Power some generators, which are connected to a heating fan. Nice insight tho, very cool to see you go from farming simulator to actual real life engines and such. Always loving the restorer videos :) Edit: Putting load on the engine gradually increases the wear of the engine. Which makes your needed testing time come down. (1-2h instead of 6h)

[@HobbyMotorDK]

Great experiment. If possible it would be interesting to see the the temperatures when running on recommended 10w-30 oil - on all 3 engines

Yes, without a control run, it doesn't tell you anything.

[@HobbyMotorDK]

@@videodistro Well is does tell you that in a pinch all three of the oils will run the engine - by comparing with 10w-30 oil is should be possible to determine which of the 3 alternative oils are best at dissipating heat

[@averyalexander2303]

@@HobbyMotorDK The oil temperature under a given load, RPM, ambient temp, etc is more of a function of the oil's viscosity than anything else. Since thicker oils create more viscous drag, they tend to run hotter. Of course there are exceptions and some oils will run hotter or cooler than others due to varying degrees of sliding friction, but for a valid comparison, the viscosity must be considered and the same engine must be used or the oil temperature being the same on all engines must be verified with a reference oil. Also, keep in mind that lower oil temps don't necessarily mean less wear or better protection. Viscous drag generally isn't harmful to the engine. And as Lake Speed Jr showed, friction and wear are two separate things and often aren't related.

This was a very interesting video. As a precision agricultural equipment technician, this is a very informative and thought-provoking video. It would have been nice to have a control engine that ran purely normal recommended engine oil. It would also be cool to see you run these engines longer and under load to really test the shear points of the different oils as well as their ability to retain lubricity under load and higher heat. Now, these engines being of lower quality also have looser tolerances allowing them to function with lower quality oils I.e oils with different sized quote "liquid ball bearings." I was surprised that the vegetable oil performed somewhat well. The gear oil and hydraulic oil. I was not surprised. Gear oil is used in differentials and axles on pretty much any form of transportation. So it is revolving at an astounding rate with lots and lots of load. EP. Your extreme pressure gear oil, especially 80w90 and 80w140 is especially common in over the road semis and Off-Road agricultural equipment. Your hydraulic oil is used in extremely high pressure situations. Sometimes upwards of 60,000 to PSI, and is ran through gear or piston style pumps and motors . The Piston style pumps and motors are basically miniature engines with a series of Pistons on a swashplate that revolve anywhere from 500 RPM up to 2500 RPM depending on its application. Not surprised that hydraulic oil performed well. But still engine oil is the best for engines hence the name

Can't say for sure on these engines, but on my duromax generator with a chonda motor, it had A LOT of glitter on the first oil change(only ran for 20 minutes to clean out any machining shavings), then had a slight bit of glitter after another 40 minutes with fresh oil, and then the glitter was essentially gone after another hour long run with fresh oil. From there, I did a 3 hour run and a 6 hour run with fresh oil each time, and noticed no glitter at all on those changes. Currently working on a 15 hour run with fresh oil, but I don't expect to see any glitter in there when I drain it(just haven't had enough power outages to make it run for that long, and only do 1 hour "exercise" runs every 60-90 days to keep things from sitting for too long. It would have been really neat to see what it did running proper oil for the first hour or so to clean out any leftovers from the machining process before starting the tests.

[@johnnodge4327]

Interesting concept. For information, the first oil change I did on a new Lifan (same is yours) engine came out looking like the yellow engine oil. The next change was much better, as the engine had broken in. So it would have been best to "run in" the engine on normal SAE 30, before switching to the test oil. Nice video though, thanks.

[@johnrgm3047]

EGT differences could be down to variations in mixture strength. to eliminate that factor you really need to run all three types of oil in all three engines, then you will be able to see if the temperature variations can be attributed to the way the engine has been set up or the type of oil used.

The temperatures are dependant on the carburetor. Lean runs warm. The automatic throttle also has an impact on the temperature. Excessive rolling will give a higher temperature.

[@aku2dimensional]

It would be interesting to know how an alternative oil mixed with regular engine oil would perform, 10W-30 mixed with Canola oil, for example. Canola oil is sometimes used as a lubricant for things such as machinery that processes food, and it would also be interesting to see if straight or mixed avocado oil would be any better than canola. Avocado oil has a high flash point at 520°F/271°C, and perhaps an oil thickener could change the viscosity so it's not as thin.

[@PopsHowTo]

I think the biggest thing you going to see with hyd oil is scoring under load due to being too thin. But this depends on the hyd oil. It also won’t have the proper detergents to handle contamination that move past the rings.

[@tomericas5357]

I have a feeling the exhaust temps vary more because of inconsistent carb tuning rather than the oil?

Back in early 90's I changed my engine oil in my 1978 Olds omega with a 231 v6. It was a hot summer day and I saw some oil in the shed that my brother had, turned out to be 80 w90 gear oil. I noticed right away later that night picking up my girlfriend about 40 kms away the valves were rattling a bit but put on about 100 kms. The next day, we went to a wedding about 150 kms away, the car engine shut off. mussed a bit and some black smoke as the oil heated it got thinner. I drained it the next day, but after about a month later the oil pump went out, it had low millage on it (40,000 kms) as I bought it from my Aunt. East coast Canada 🇨🇦 NB province here.

Reeaally wish there had been a control engine using the proper lubrication. Even if you release it as a "Part 2," it'll still be relevant. Edit: I'd also curious to see one running on ATF or Diesel fuel. Thanks!

[@MrZorbatron]

A lot of hydraulic oils have a high detergent level, which can scrub the surfaces. It's kind of like running an engine with automatic trans fluid in it instead. This will especially be noticeable with a new cheap engine that may never have been run at all (lots of manufacturing debris and dust).

[@benmcknight6865]

Great vid but May I suggest also having a control test with the normal recommended oil

[@damiendesrosiers3148]

Maybe the vegetable oil was actually igniting a bit as it came out the exhaust. Could that explain the the high exhaust temp with vegetable oil?

[@armadildo6468]

Can we do this with avocado oil. Its smoke temp is 500 degrees.

[@johnbradford9235]

Loved that little test Mr. Machinery Restorer 👍👍👍!!! Not that I wish for drama, but I waaaaas kinda waiting for one of 'em to go pop 😂. Guess I'll stock up on the Crisp 'n' Dry ay 😉😁. 😎

[@SockyNoob]

Reminds me of old school Project Farm videos.

[@specter6633]

Missed an opportunity to include the recommended oil. Also next one try with engine already preran with recommend so maybe the filings could be gone. Or maybe see how many cycles till the shaving are all gone. Cool upload non the less.

[@MoldyStir-Fry]

This is a really interesting experiment... Maybe there are more fluids that can work as engine oil for a sequel episode?

[@jaidee9570]

I've bought a 35.8 cc Chinese petrol strimmer mounted on a frame with wheels. It's a clone of the Honda unit, and all in cost me about 60 pounds. I bought it because once a month I clear the very rapid tough as old boots grass that grows over the road, which the local authorities aren't interested in clearing. I've cleared it twice so far and if it survives a third time it'll have been cheaper than paying someone to do. I've no idea how often one should change the oil, but it only holds 100ml so perhaps every other month would be a good plan. As interesting as this was, I don't think I'll copy your experiment, a litre of fully synth 10W40 was 2.25 the same amount of vegetable oil would be about half that. But if was interesting. I'm no mechanic but what is the most likely casualty of a consistently high temp exhaust as you saw when using veg oil?

[@H3R854LIF3]

Do these small mower engines have magnet in sump?

[@jasonmansfieldsr8645]

I recall witnessing a military truck engine being serviced with gear oil instead of engine oil. Well, I was on the convoy when it was discovered. Dunno what the disposition was when it was sent back to the shop but it did drive at least 350 miles…

[@colinstickland3130]

Bought them engines in the past. After half hour they burn more oil than petrol. . but a honda ?? Still using it on my cultivator. 4 yrs on. Regular oil change . Brilliant engine

[@Azureecosse]

During the 2nd world war my father had a Norton motorbike he could not get engine oil it was hard to get, he was in the army so he ran his bike on Gun oil, he said it ran OK but it did need a decoke once in a while, he had that bike up to the 60s and it never gave him any trouble mechanically.

[@Transit_Biker]

Control engine with recommended oil would have been a good addition.

[@robertpeters9438]

Try the test with regular oil and Lucas oil extender! Again with synthetic.

[@BGWenterprises]

Was the hydraulic oil the common iso-47 15w or. iso-32 10w Iso-68 20w . There are others, but those 3 are the most common.

[@BGWenterprises]

I've found a oil cooler and removal of the rope start, seriously helps these little engines run much cooler.

[@johnangelico667]

Hydraulic Oil - what was the ISO viscosity and I presume it was a regular natural oil, not a synthetic?

[@5argetech56]

I use Castrol 5 W 30 full synthetic in both my car, and my small engines!

[@ofp8574]

It would have been nice to have one motor run with 30W motor oil just as a control. Also, it isn't particularly surprising to me that all three survived. Before rapeseed oil was deemed suitable for human consumption, it was used for industrial lubrication. As for gear oil and hydraulic oil, both are petroleum based. I know when doing a comparison of the hydraulic oil I use for my tractor, and some 30w motor oil, the viscosity was extremely similar, and both were similarly slippery, although the hydraulic oil in this video is likely more modern, low viscosity stuff. Gear oil is also not nearly as thick as one would think, if I am not mistaken, 80w gear oil is of similar viscosity to 50w motor oil. Bear in mind, I am not fact checking any of this information, and may be misremembering certain things, but as far as small engines go, if non detergent oil will work, oils of other additive packages like gear oil, transmission fluid, or otherwise, should function passably. As for rapeseed oil, while it is a lubricant, I would imagine that it would gum up pretty severely as it is exposed to the residue from burning gasoline, along with being a bit too thin to well lubricate wear surfaces. I know when lubricating old firearms, the old organic based lubricant that was used in the black powder days will get sticky if you add petroleum based lubricant without first removing the old lubricant.

[@s.a.m_e.v.a.n.s]

Used to rebuild real honda GX engines for tool hire machines. Even the real deal used to have metallic oil after the first run

[@Akotski-ys9rr]

One time I put oil that was slighter lighter than what it called for in my lawnmower assuming it would be fine, and it started smoking a little bit and running rough which really surprised me. I then got the correct oil and replaced it and it ran perfectly again.

[@Akotski-ys9rr]

Daggerwin? I wasn’t expecting your voice. Pleasant surprise

[@justacommunisthater]

I wonder how hydraulic with stp additive would test against regular engine oil...

[@DougDeMuroFan]

0:44 bro sounds like DIY perks

[@navahrnlaucke6194]

What weight hydrolic oil did you use?

[@heliarche]

As other guys are saying, control engine with the recommended oil and all of them running under load. Just sitting there running isn't much of a test and I'd like to see if it dumps so much glitter with the recommended oil.

[@drewfobear435]

What was that camera you used to see inside the cylinder?

[@kenibnanak5554]

It would have been nice if there had been two baselines of Mobile1 and a cheap oil like Penn to compare the result against.

[@robertagosto9252]

When did the flush and clean and run two more cycles with the same and let's see which engine holds up the best

[@ajwalou-nack2343]

Where did you get the engines from for only £60 ? Thanks

[@bidders77]

Where did you source the engines at that price? Might grab one myself
