Has anyone ever had their low oil light come on in extremely cold weather? I have checked my fluid several times and the level is fine. but it is about -30 dregrees here. When i start the car cold the light will come one, but if the engine is warm... it only comes on sometimes. its pretty weird. just wondering if anyone has had this problem.

 

what kind/wt of oil and what oil filter are you using? what motor and how many miles?

 

its a 1995 with a 3.8L and about 150,000 miles. I am currently using 5w30 oil and i believe just a fram high milage filter.

 

oh and pennzoil.

 

get rid of the fram filter and see if that helps. i think its the tough guard or something like that that is not any good and can mess the oil pressure up. filter can also to pieces. get a good one to replace it.

 

You are talking about the light for the oil level in the pan, right? Running the engine (no matter what filter it has) wouldn't cause a low level, unless the pan is getting sucked dry which wouldn't be happening to a full pan. It's probably a funky sending unit or the wiring. Out of curiousity, what is your oil pressure reading?
Btw, it's the orange Fram oil filters that are the bad design ones. The tough guard (TG) and extra guard (XG) are ok.

 

ahhh i guess i should have paid more attention to his post. yep most likely the oil level sensor is failing. its on the side of the oil pan.

 

My oil pressure is reading about 85 when cruising and about 100 when I punch it. I will hopefully get an oil change done this weekend... it needs it... bout to turn 150K miles.

 

wow my gauge only goes to 80 and its never been pegged. what mark on the gauge are you on? on mine the first mark is 20 lbs.

 

I know, that does sound high doesn't it. My LT1 is almost 80 on a cold engine, 40 at idle hot. Or, do 3.8's generally run higher than that?
