EV or ICE

That's more of a reason not to use the same check engine lights for evap codes. Though your oil pressure light would hopefully go on. I prefer an actual gauge and that is often done by pressure, not by computer. Even then a redundancy for not having enough oil pressure should have additional check points.

But it's a big difference between oil pressure and a system that's constantly giving you error codes.

Most car gauges even old school are estimated pressure as it's based on resistance produced by piezoelectric versus a signal that increases or decreases that is better .unless you are talking about the bourbon guage

jasonc yeah, the old school method is best. If done right too the low oil notification is also good to have.

King Dan of Great the 1st that's crazy. When I do my oil changes, I'll be making sure that light works. It will stay on in ACC or on (not running) mode when I drain the oil out. It will come on when I have under 2.5 quarts, capacity is 4.7 quarts.

It is crazy. A few vehicles I have owned I never seen the oil light come on even when low.

Like this time I thought it was just a stone in the wheel making ticking noises, only after a long time when I parked up the oil light just flicked on and off quickly and I thought better check and it was bone dry. As soon as I put oil in the noise went away, it's running fine but who knows if it has caused any damage. Guess the only thing i can do is get a oil pressure test just to at least make sure that's all good. It's been a while and long distance and no issues or weird things happening it's running smooth. Who knows maybe was just lucky.

King Dan of Great the 1st that's pretty interesting, what vehicles had the low oil light never on? My vehicle that I mentioned is a 2000 Pontiac Grand Am GT. The low oil light appears to be set correctly, some cars I guess are not set up to show low oil when capacity is around half or lower. I also use full synthetic oil, don't know if that makes a difference.

Something about that I remember..

I don't know what's worse. A faulty sensor that locks your vehicle down and can't do anything or a warning light that doesn't even work.

I mean I ran out of oil and the light didn't even come on. What's the point in having a oil light if it doesn't even come on when low. Nearly seized my car.

In older vehicles where you turned a key from off to accessory and then to start, while in the accessory position, before you turn it to start the vehicle, it will light up all fault sensor indicators. If you do not see an oil pressure, engine temp, brake, or other fault indicator light up at that time, it means there is something wrong with that sensor circuit. Could be just a burned out light or a bad sensor. In newer vehicles like mine with the push button start, all the fault sensors are displayed for a few seconds after the vehicle starts. Again, this gives the driver an opportunity to see that all the sensors are functioning. It's our responsibility as vehicle owners to know our vehicles and all of this is explained in the owner's manual. You know, that book that you find in the glove box and most people throw away.

If it's constantly giving you error codes, maybe there's something wrong that needs attention. If it's constantly giving erroneous error codes, then there is something wrong that needs attention. If you choose not to make the repair, then the onus is back on you.

A bulb check ,

Well you are correct but I have found alldatadiy.com to be useful for the particular car I need to fix

Older vehicles rarely used an oil level sensor but only tested for oil pressure. If your level is low enough that the pump is sucking air, you'll get a low pressure indication and need to have the vehicle serviced.

Oil level sensors replace the dipstick .it measures volume and pressure over time akin to a maf .

Yes. The oil pump will not run dry unless the oil level drops below the level of the pick up and that can be quite low, maybe as low as just 2 quarts. There are two reasons that I am aware of for having the excess volume above that amount. One reason is heat dissipation. Having 5 or 6 quarts gives more volume to absorb heat and give the oil a chance to remain cooler. A second reason is having 5 or 6 quarts allows for more capacity to suspend contaminants otherwise the oil would need to be changed way too often to be practical. Diesel engines are notoriously more sooty than gasoline and this is why the oil capacity is even higher. The extra capacity to suspend the contaminants also makes filtering the oil more efficient.

I was explaining how the oil level sensor works.i have changed oil on bmws and Volkswagen that don't have dipsticks .the ecm can tell you how much to add and you must run the engine for so long for it to see it.

Designed by a dipstick . I mean come on man ! I want an oil dipstick , you can SEE what the condition of the oil looks like , it could be contaminated with gas or coolant .
VW Beetle from the factory, no oil filter at all . Get a filter kit and add it on , JC Whitney don't you know . Back in the day my friends .

I never said I think it's a good idea

Of course you didn't think it was a good idea , I knew that . I imagine the dipstick delete was to save money production wise and keep the end user out from under the hood too . What do you think ?

I'm not sure as these are luxury cars

Makes sense to me that it would be luxury cars , the first owner might not ever even pop the hood open to check anything .

A high end Malibu has that .there is the run dry transmission were you really can't refill them easily .

The idiots who decided to install batteries underneath a seat and have it electric adjustable .so if you don't have a way to jump it .good luck .

That low oil light was put in for the female population. It reminds them to tell their husbands an oil light came on in my car...

I got a oil light. Before start the vehicle all the symbols show. It's red with a oil can and drip as symbol. Must not work because I ran out of oil and it didn't come on and warn me like a fuel light when running low on gas.

And what's the battery one for. A red battery symbol. I got flat battery other week had to get a new battery that didn't warn me either when it was getting low and crapping out all the time.

Before start heaps of lights come on and some turn off and others stay on. Like oil, engine, battery and brake stay on but like airbag and temp and that go off. Start the vehicle they all go off. What's the point in all this.
