Because the losers weren't worthy

I have been watching with described audio subtitles because a lot of times they capture stuff that you'd never hear or pay attention to. Like an exiting character's background conversation with another character which is barely audible will be written out.

Sigh. Have a good week my dude

The oil pressure gauge does not tell you how high the sump level is. I.e shut the engine off, pump makes no pressure but sump could be high. The oil pressure gauge ( not a low oil level warning light) shows increments of pressure in your engine block channels which is unrelated to oil level, unless you have run the sump dry and are trying to pump air. But even with a full sump, oil presdur varies by engine temperature, and other flow issues like blocked oil filter or a filter that switched to bypass mode. How is it that you cannot comprehend these things dude LOL

Like for fun, or you mean without change?

So now you resort to trolling? Dude, by your other comments its clear you don't understand cars of fluid systems. You were claiming OBD doesn't work with car running.

Oil pressure is created by your oil pump, not by the volume of oil you hold in the sump, its not a head well. But the pressure you read changes by a lot of factors, which I attempted to educate you on.

Its sad that you have dug in and can't see that.

No, you can have oil within your min - max range and still have same oil pressure because its a sump system.

Oil pressure is not a good/bad measure, its a range.

Oil pressure tells you about restriction, viscosity, flow. You could have perfect oil level and various pressure readings depending on what is wrong in the engine.

You can't tell that with an idiot light.

Oil level is not oil pressure, they are different issues.

You missed the whole part about trending changes and maintenance prediction.
Oil pressure shows you live, what is happening inside the engine. Its why Race cars , Drag Cars have giant gauges for oil pressure, etc.

Yourportion you clipped from wiki, further proves my point. Its for idiots that didn't watch their gauges.

Of course as a car guy you check oil level, coolant level, brake fluid level, but you want live data so you know what happening when engine is running. You can prevent failure before any warning light will.

Maybe you are a computer guy: do you want your PC shutting off to thermally protect itself without warning, or do you want to compare fan rpm and CPU temp trends to spot if you have thermal issues rising. Which could indicate thermal paste issue, or you have some other thing loading the system when you thought it was just your game.

People that can glean info from daily data trends know why gauges are important, even on industrialmachineas. Idiots just want a light to tell them something is already failing. It's the difference between reactive maintenance and proactive maintennace.

Per wiki.:

The "idiot light" terminology arises from popular frustration with automakers' use of lights for crucial functions which could previously be monitored by gauges, so a troublesome condition could be detected and corrected early. Such early detection of problems with, for example, engine temperature or oil pressure or charging system operation is not possible via an idiot light, which lights only when a fault has already occurred – thus providing no advance warnings or details of the malfunction's extent.

Oil pressure is different than oil level. And a temp gauge and battery gauge tell you what happening.

As you drive your car you get used to what the normal mode is, and when it starts to deviate you get clues to what might be going on in your engine.

I.e. I'd start my truck and as it warmed up before the first traffic light, then on the trip to work it had a normal range for summer and winter. When I started to see temp gauge climb higher than usual, and then stay there a long time then suddenly drop super low , it tells you your thermostat for coolant flow is starting to stick closed, and probably needs replacing.

For oil pressure you see a normal range , but if temp is up and oil pressure drops you are overheating the engine and losing lubrication. Or if pressure suddenly went down it could be blocked d oil filter, or if it suddenly is fine it can mean the bypass has opened and you are no longer filtering oil.

Idiot lights don't tell you any of this, only what has failed when it totally fails

😀 yeah it made sense to me because I grew up in the changeover.

But here's the Wiki entry.

The "idiot light" terminology arises from popular frustration with automakers' use of lights for crucial functions which could previously be monitored by gauges, so a troublesome condition could be detected and corrected early. Such early detection of problems with, for example, engine temperature or oil pressure or charging system operation is not possible via an idiot light, which lights only when a fault has already occurred – thus providing no advance warnings or details of the malfunction's extent.

I rest my case.
