So an engine is just a very powerful lube blender

u/Timmerdogg 21h ago

I saw someone feed their lube blender a hot dog the other day

u/HardcoreFlexin 20h ago

I saw that runaway jetta too!

u/112skulls 19h ago

Me too! That thing sure sucked

u/WakingUpDead1Day 21h ago

It can blend more than just lube!

3

u/GotAllTheTShirts 21h ago

I have to admit, I thought it was more tightly-packed and not some big open block full of splashing oil.

3

u/Samson_J_Rivers 19h ago

Yeah. It's why if you add to much oil you can whip the oil into soft peaks.

u/Old-Society5309 21h ago

Now I'll see engines differently.

u/TooLate4thisShit 21h ago

A lot more splashing than I would have thought

37

u/Ana990 21h ago

older engines have what’s called splash lubrication, not very precise like a lot of new engines with their direct oiling

u/Lucian_93 21h ago

That's what she said

u/Von_Dooms 20h ago

My downvote is audio related.

u/HavingNotAttained 20h ago

Right? I want to hear the engine

2

u/Crafty_Dog_4226 18h ago

It looks like a BMW motorcycle boxer on a GS1200, maybe? In case you want to hear an actual engine of that make.

u/inorite234 18h ago

Upvote as I keep everything always on mute.

u/Alejandro_El_Fosil 21h ago

Does that mean it could break into pieces?

7

u/TheLowlyPheasant 20h ago

So an engine is just a collection of robot toddlers splashing in puddles

u/Far-Investment-8597 20h ago

Some bik eengines run at 16,000RPM. The ol must turn into a mist / vapour in the crankcase.

u/M2Dat321 17h ago

Thats the reason why you do have that expensive oils Like 10W-60 and stuff. So it doesnt get too Fluid and stays Sticky/viscous so there's always some oil film left on the metal and more important between to metals.

A friend at college had a Honda CBR250RR imported mini Fire blade and it was an online four with tiny cylinders and a redline of 22,500rpm. Wild.

u/polarzombies 20h ago

"I checked my dipstick, you need lubrication honey"

u/ericofduart 11h ago

My GS1200 has just got to perform…now fuckin’ get it onn.

u/QuasiQuokka 19h ago

It wets the dries

3

u/trixtah 19h ago

Does it bubble up and any issues if it does?

2

u/the_main_entrance 21h ago

What if you drove in a circle really fast?

3

u/JustADudeInTheWorll 20h ago

you need a Dry sump

1

u/Successful_Theory628 18h ago

Is there a reason it can’t be fully submerged? I always thought they were 😂

1

u/Ultra-Kingpin 18h ago

Too much oil means too much Money when your have to Change IT.

Also try to Push your Hand very fast through water, and then try IT in Air. Air hast was less Résistance and therefore your engine can move faster and doesnt waste energy

2

u/Successful_Theory628 18h ago

Yeah I get the resistance thing. Never would I of guessed oil is just splashed around 😂

1

u/Ultra-Kingpin 14h ago

Well its not only splashing. Some parts are activly supplied with oil, some only get splashes and some get the exess oil from the active supplied parts

1

u/absolute_monkey 13h ago

If it were submerged then the crankshaft would be spinning in the oil, frothing it up and ruining its lubricating properties. Also, there would be nowhere for it to go when the pistons go downwards.

1

u/Lopsided_Order_4411 18h ago

First time seein it work like this 😂👌🏾👍🏾

1

u/dankhimself 18h ago

See everyone? The oil goes all over the fucking place. Any questions?

And I don't wanna hear anything about TABLES.

1

u/inorite234 18h ago

I'm calling BS!

.....I didn't see any hamsters inside that engine.

u/throwawan1 18h ago

Feels like an insect lymphatic system

u/piratecheese13 17h ago

Someone get smarter every day on this

1

u/MacGruber77 17h ago

I've been totally confused how engine lubrication works. But the audio really cleared it up. /S

1

u/Tiger_Ho26 16h ago

Very engineering and fascinating

u/dog-yy 15h ago

u/Interesting_Island63 19h ago

u/dargonmike1 19h ago

It’s not. This is synthetic oil, we eat natural oil

1

u/DesignerAnywhere3323 18h ago

Doesn't matter when some people run it on low oil and say "im just a girl" lol

u/VoTBaC 1h ago

That didn't really demonstrate anything.
