My oil light keeps coming on (2000 buick lesabre). First came on -oil was low. filled up oil-2 quarts-still on. got oil change-still on. do I need to replace the oil pressure sensor or switch. If so, where is it located.

My info says 5 quarts with filter. I don't know where the leak is coming from? My database isn't always correct, but, that's what it said.

Should be about 4.
When you add 4, then park the car on a level surface, and wait about 15 minutes, and then check the level with the dipstick.
The low line and the full line are 1 quart apart.
Be blessed.

Takes 5 quarts to fill including the filter. good luck to you.

Hello
There are 4.5 qaurts of oil added to a 2000 buick if the filter is changed and almost everbody changes the filter

You will need 4 quarts of 10W30. just remember to check the level if you are changing the filter too. You usually need to add another half quart.

replace oil sending unit its not hurting the car if your oil is full end the light is still on then you have a bad oil sending unit cheap to fix yourself

look for the fitting that is the smaller of the two and is attached to the line that is the larger of the two, this is the "low" fill side, add 2 cans of r134a freon each can is one pound the system empty holds 2 3/4 pounds of freon thats 2 3/4 cans.
I would buy 1 can of leak detector/freon combo and one can of dye/freon combo, if it takes more add a small amount of a third can that has an oil mixture in with the freon that would complete your systems needs the cheapest and fastest way possible.
If you want it done to the book then you need to have a certified A/C man vacumn pump down the system, replace the reciever drier, add freon and oil to fill the system and then check for leaks.
Happy Motoring!!

If the trans. fluid gets down , even a quart, it usually starts to slip or not shift right. Check the fluid with the engine running and warmed up on level ground (in park). If it's low start adding fluid about 1/2 a quart at a time and keep checking it. Watch for leaks while you're filling it. If no leaks are found take it for a test drive and check the fluid again.

CHANGE OIL SOON Light
1. CHANGE OIL SOON light will come on when engine oil has broken down enough to require changing. After changing oil, reset oil life display.
2. To reset light, turn ignition on. Open glove box to access oil reset button. Press and hold oil reset button in glove box for at least 5 seconds, but not longer
than 60 seconds. The CHANGE OIL SOON light will flash 4 times to indicate light has been reset.

check your oil level
if it is showing just below the fill line it will shut off due to lack of oil
keep a couple of quarts handy
