• Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

has anyone had the low oil pressure light come on when you have low oil pressure, like it's supposed to?...not counting when you put the car in accessory mode like the below photo shows...also please share how much oil was left in the car when the light came on...i assume the dipstick will not show any oil and i assume no one has drained the oil when this happens to find out at what volume the light comes on

I answered "no, i monitor my oil now that i know these engines are designed to consume oil" although there is nothing deliberate about these engines consuming a little oil.

The design of a two-stroke deliberately consumes oil to lubricate the bearings, then it is burned. The design of a Wankel deliberately consumes oil to lubricate the rotor tip seals, then it is burned.

Four stroke engines are not deliberately designed to consume oil; it is a side effect of the fact that a tiny bit of oil is used to lubricate the compression rings as the pistons travel up and down and a tiny bit of that oil is inevitably burned when the cylinder walls are exposed during each power stroke. There is also some oil that may come down the valve guides though there are typically little rubber tents (aka seals) installed over the valve stems to minimize this..

A four stroke exhibiting excessive oil consumption might have damaged or worn piston rings, scored cylinder walls, or worn valve guides. Or a combination.
