i remember advice from my old garage that if the oil light comes on on newer skoda/vw damage is being done as its based on oil pressure not oil level. You should stop engine and check oillevel immediatley as oil level could be critically low On older cars you had an oil level sensor and oil pressure so you get a bit more warning when level was low. My old volvo 940 used to ping up warning if I took corners too hard.

Same warning light comes on yellow to indicate low level, as read by sensor in sump.

Some older engines may not have level/temperature sender in sump, but most do.

Any that can be set to variable/longlife service schedule will have it.
