Default Oil Sensor question - Colder mornings in Houston

I can't get a straight answer from the car so I thought I'd post the question here.

Is there somthing about the oil sensor that shows the amount of oil during the startup checks that can be affected by colder weather. I know I have pretty much full tank of oil and it's only showing 2 bars on the display. I pull the dipstick out and there's no oil on it at all.

I start the engine and it's a smooth as can be, no puddles or leaks of oil on my floor so where is it....

I would definitely trust your dipstick over the measuring sensor anyday!!!! unless for some crazy reason, you could have the wrong dipstick ??? If you got nothing on the stick......you are low!! Naturally your oil will contract in the cold temps, as it will expand in hot temps....hence showing less oil on a cold day.

no oil on dipstick?

you better add a little and see whats going on...try 1/2 qt and then check the dipstick and see if the sensor reads the same or higher

if the sensor still says the same and nothing on the dipstick (or very little) keep adding in small incriments till you get a sense of what its telling you

IF you happen to overfill there are ways of removing some... but nothing on the dipstick doesnt sound right...at some point they should agree.. (ie a little on the dipstick and a few bars)

I drove it yesterday and it showed 90% full , then i get in this morning and it's saying its only 20% full. Doesn't sound right at all, New engine, might just take it to the dealer after lunch and let them figure it out, I might get a free oil change out of it.

Oil should be middle of the dimples on the stick, and should be close to the dash oil display.

sensors have been known to fail - though rare, bit of a PITA to replce because they are very long and inserted from the top IIRC (dont quote me, my brain is a tad sluggish this millenium)

Mine shows 2 bars down sometimes on the inside indicator. Once I run it and it gets warm it usually shows full. The dipstick is right at full once warmed up as well.

Warm it up and recheck, you don't want it low but also don't want it overfilled. Cold weather does drop the levels slightly. Proper check is with it a little warm not freezing cold.
High speed driving like at the track will consume more oil than just regular around town driving. Done any of that recently ?

Dipstick is a physical measurement...I would trust that one, regardless of the temp.

There will be some recession with cold temps....but not THAT much.

It's minus 30 here...and I lose an 1/8 of an inch on the dipstick when cold.

Yeah man but drove it real friendly like yesterday and oil level was fine, either that or it's got a built in delay .....

i know, silly question, but you are checking the dipstick with the car on a level surface, correct?
