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.

I rest my case.

Maybe my vehicles were old enough before that electronic averaging. 90s. The oil pressure and temperature would respond as the engine warmed, or as you revved it. Sitting in traffic on a hot day and you could watch the temp gauge climb, and then drop when you started moving.

This is like when cars went from oil pressure and temperature gauges to "idiot" lights. One let's you see trends in situations and be prepared for maintenance, the other tells why your car broke down.

English is a mess because the characters don't match the sounds used in many words. Like tough vs though. Which Is different to say Serbian, or most other languages where the letter always has the same sound.

But accents are slightly different than different letter sounds aswell

For example you can have people with the same accent speak different sounds on words. Like a person that says the herb as Bayzil compared to somebody that says Bahsil, even with same accent.

That many satellites with controlled directional reflection will get used as a weapon, either purposely or via hacking. You aim several of those at one spot you'll be scorching zones instantly

I don't understand this 😜

I had a boss have a stack of resumes dropped on his desk, he saw a yellow one in the pile and immediately picked it out and tossed it without reading it.

I was like what the heck, and he said something like " they wanted to stand out and they did, goodbye"
