I work in a shop and the amount of work your car does regularly is wild. I also still have a pic of a VVT solenoid that needed to be replaced, along with a new one. You can see the buildup on the screens that inhibit its operation

I think you underestimate what a piece of black electrical tape on the instrument cluster when combined with a hope & a prayer 🙏 can do for the longevity of a vehicle.

Great vid, I enjoyed watching with friends who aren't into cars, them learning about my main hobby was great
My only thought is I don't recall anything about how to check levels with a dipstick (or to check the manual if they don't have one). Usually if the light is on, damage is already happening.

The timing of this may seem weird given my last video and ~world events~ but what I'm really trying to do with these videos is to get folks who don't understand much about engines to get to where I'm at:
These contraptions are insane and the only reason we don't think that is b/c we're used to 'em.

your framing of the "you are buying the fuel to SET IT ON FIRE" in the renewables video has kept coming up in my brain every time I see a gigantic truck driving around these days lol

Perfectly normal to just sit on top of a hunk of metal constantly making tiny explosions and letting it pull us around at tremendous speeds.

It's like we opted for gas engines over electric when we were up to our eyeballs in cheap oil (Spindletop and beyond).

There's literally no dimension in which ICE is better than EV. Having a vehicle the runs on explosive liquid will sooner or later be a niche hobby like having a horse.

There are those people who deny themselves engine maintenance as like some sort of "getting ripped off by the oil industry" flex, but it really matters that the machine with parts exceeding thousands of RPMs doesn't decide to weld itself to other parts.

The modern internal combustion engine is a miracle and then another miracle’s worth of tricks and hacks to get it so efficient we’re probably at 95% of what is *physically* possible.
There’s really no tech or gains to be made there anymore. We reached the apex.

Seriously, I am used to them, I have torn apart gas, and diesel engines, I still think they are insane. "so we harness the power of small scale explosions in a tightly enclosed space, by pumping burny juice from huge tank of burny juice, and then make it explode, several thousand times a minute."

Just watched your conversation with Matt Ferrell and his brother and really enjoyed it. This bit about how crazy engines are and also the bit about people need to just pull on the thread and learn things was great.

Carrier aircraft during WWII had to spend 15 minutes warming up on the flight deck before taking off because if the oil wasn't at working temperature and the pilot applied full military power the engine would explode.
Engines are very cantankerous.

I work in hardware, and I'm in constant amazement at how insane the technology at our fingertips is. The decades of brainpower gone into protocols and digital designs are constantly blowing my mind. Cars and engines are the same. We take a lot for granted because we see them every day!

The internal combustion engine is a modern marvel and it's a miracle we ever figured out how to get them to work and as such are fascinating. They are also very bad for the environment. That you convey these two things well is one reason I really enjoy your channel.

They're also engineered *WAY* past what they need to be for reliability. The spacing between cylinders, the mixing of metals on mounted surfaces, the insistence on getting the maximum horsepower out of every cubic centimeter of displacement. A reliable engine would only need to be 10-15% heavier.

Internal combustion engines are genuinely a marvel. The level of mechanical complexity appeals to the same part of my brain that loves pinball. However, pinball (to my knowledge) doesn’t regularly cause wars, crash the economy, destroy the earth, and depend on consuming massive amounts of oil.

Am I right to describe ICE vehicles as being propelled via a series of sustained explosions of toxic chemicals?

Your video about the sensors on the catalytic converter made me appreciate just how complicated ICE engines are. It's one reason why the high price of EVs is so perplexing... Electric motors are so much simpler, why do we pay a price premium for them? Is it all in the cost of the batteries?

To me the timing mostly seems weird because a friend of mine had to cancel plans because their car broke down because a lack of oil exactly two hours ago when this video was published.
If only you got it out a little sooner!

I expect an object to spend its entire lifetime outside in the elements, careen at 100kmh for 2 hours per day while keeping me perfectly safe and comfortable, pay fuckall for its maintenance despite doing this for years and pay only as much as 200 McMeals because it’s secondhand. It’s incredible!

Well, both videos can (sure, not quite) be summarised as „Abolish ICE“. That's close enough for me.

@techconnectify.bsky.social As a German mechanical engineer I'm of course fascinated with engines and also baffled by how cheaply they can be made today. It'll be wild to see what the world might look like with the same level of optimization going into electric drive trains and I can't wait […]

I've always loved engines a lot, but honestly, you kinda changed my mind with the video you made about a month back. I watched the engine video immediately before watching that one, and your emphasis on superior longevity, operating costs, and permanent infrastructure changed my mind instantly.

As an automotive enthusiast I loved this video and this series! You are so good at explaining things in a way that most gearheads just aren't. I've been sending this series to friends of mine because I know they'll actually learn something!

Just want to say as someone who grew up with a gearhead for a father who has been knuckle deep in my own vehicles many times and will be again now that the weather has gotten nice, you did a great job explaining the fundamentals and how vital the oil of the engine is.
Take care of your cars.

Your video and Garbage Time really made me realise how mechanics I feel are sorta seen as having (because of the ubiquitousness of cars I guess) having a sort of strenuous but not super complex job if that makes sense? Like engines are made and maintained with such precision it’s crazy.

Old school railroad journal bearings are a real hoot. A fiber pad sitting in oil would keep the rotating shaft wet with a thin film of oil. These were a major maintenance headache and failures were common. If you ever see a railcar w/ a hinged door on the axle, this is what is inside.

Whenever I learn anything about how combustion engines work my overriding thought is how intrinsically stupid it is to make our cars do all this compared to just having an electric motor

A quick comment on the video (here because I fighting the YT comment interface errors today), in my personal experience, total loss of oil while driving isn’t usually done by a pump going bad but by oil pan damage if you drive over rough roads, like every badly maintained road with deep potholes.

My dad and I do our own oil changes in his garage (with 4-post pneumatic lift and vintage Hunter Original ceiling fan). First time we did the Hyundai Santa Fe I used to have we didn't put the drain plug on tight enough and most of the oil leaked out before I'd gone 5 miles...

Ugh. This reminds me I'm overdue to get my oil changed. Why did oil changes get so outrageously expensive?

Truthfully I have not been keeping up with the cost of oil changes because for the cars I have which need them I'll do it myself but I will say at least in the past oil changes were pretty cheap at places like Midas.
And honestly a place like Jiffy Lube is fine. Gearheads are too mean about them.

My understanding of the reason for filling the oil filter is less “small period of time with no oil” and more “unmeasured void of space where oil generally sits” - ie, that there will be oil in that filter at all times and that filling the oil without filling the filter might mean the oil is low…

regarding oil changes and EVs :
It should be changed. The problem is that most oil development has been for combustion engines which has pulses of power, while EVs have constant power, and friction/lubrication is far more complicated than how most people understand.

historically electric motor efficiency has been "eh" of an issue, so we have historically used thick grease (which is why overdriven wind turbines catch fire, its the grease breaking down). Only recently has electric motor efficiency gotten to be an issue because of EVs, so the tech is catching up.
