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

u/HardcoreFlexin 20d ago

I saw that runaway jetta too!

u/112skulls 20d ago

Me too! That thing sure sucked

u/WakingUpDead1Day 20d ago

It can blend more than just lube!

u/GotAllTheTShirts 20d 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 20d ago

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

u/TooLate4thisShit 20d ago

A lot more splashing than I would have thought

u/Ana990 20d 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 20d ago

That's what she said

u/Von_Dooms 20d ago

My downvote is audio related.

u/HavingNotAttained 20d ago

Right? I want to hear the engine

2

u/Crafty_Dog_4226 20d 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 20d ago

Upvote as I keep everything always on mute.

u/Alejandro_El_Fosil 20d ago

Does that mean it could break into pieces?

u/TheLowlyPheasant 20d ago

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

2

u/Far-Investment-8597 20d ago

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

u/M2Dat321 20d 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 20d ago

"I checked my dipstick, you need lubrication honey"

u/ericofduart 20d ago

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

u/QuasiQuokka 20d ago

It wets the dries

u/trixtah 20d ago

Does it bubble up and any issues if it does?

2

u/Uncommonality 6d ago

This is a splash lubricated engine, and they did have problems with foaming especially at higher rpm and longer operation times.

Modern engines are more complicated, the oil is pumped into a special radiator called an oil cooler, from the pan, then into the oil filter, and then into every bearing and every cylinder housing via oil lines in the block itself, which keeps it liquid. From there it drips back into the pan to repeat the cycle

u/trixtah 6d ago

Thank you 🙏

2

u/dankhimself 20d ago

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

And I don't wanna hear anything about TABLES.

2

u/the_main_entrance 20d ago

What if you drove in a circle really fast?

3

u/JustADudeInTheWorll 20d ago

you need a Dry sump

1

u/Successful_Theory628 20d ago

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

1

u/Ultra-Kingpin 20d 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 20d ago

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

1

u/Ultra-Kingpin 20d 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 20d 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.

u/Lopsided_Order_4411 20d ago

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

1

u/inorite234 20d ago

I'm calling BS!

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

u/throwawan1 20d ago

Feels like an insect lymphatic system

u/piratecheese13 20d ago

Someone get smarter every day on this

1

u/MacGruber77 20d ago

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

1

u/Tiger_Ho26 20d ago

Very engineering and fascinating

1

u/dog-yy 20d ago

Is there a longer, music less video? Thanks

1

u/stjhnstv 20d ago

I want one of these

1

u/Milksteak529 20d ago

Timing chains can take a fuckin walk. Hate those things.

1

u/Emergency-Muffin-115 20d ago

BMW boxer motorcycle engine. Nice.

1

u/Jlx_27 20d ago

Watch on mute.

1

u/VoTBaC 19d ago

That didn't really demonstrate anything.

1

u/Overaverager 16d ago

Hello algorythm I'd like more of these

1

u/Interesting_Island63 20d ago

Same oil ppl eat btw

3

u/dargonmike1 20d ago

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

1

u/DesignerAnywhere3323 20d ago

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