Check and make sure your engine has the recommend amount. When you stop your vehicle the engine is at idle and has a lower oil pressure then when your car is driving. A oil light is a pressure gauge, when the light is on when stopped is the first sign of an oil leak, most likely the oil pan gasket.

It's not hard ,but you need to know if there might be any obstruction that might get in the way preventing you dropping the pan down just make sure all the oil is drained before you start ,and make sure you clean both surfaces thoroughly before putting gasket on ,and you must tighten all bolts or screws evenly or it will leak .

The cheapest place is to get one from a junk yard, but you can probably still get them through the dealer.

A 2003-05 Sunfire most likely has the Ecotec 2.2 motor. The filter is a cartridge element type which is located on the forward side of the engine on the drivers side; (below and slightly left of the power steering reservoir).

The oil filter is located under (inside) a black cover about 3-4 inches around and has a large hex head nut molded on top of it, to fit a socket on it. When replacing the oil filter element, press the tipped O-ring side of the filter down into the filter cavity until it locks in place. Then place the cover on top and tighten it.

The cover will automatically lock onto the top section of the oil element as it is being tightened. The drain plug is pretty standard and on the oil pan. However, most people are accustomed to a metal oil pan, and when viewing the Ecotec motor they confuse the metal TRANSMISSION pan as the motor oil pan.

The motor oil pan is actually aluminum, and looks like a continuation of the upper motor. For that reason, you don't "see" an oil pan. Knowing this fact, the oil drain plug is now easy to locate. Look at the far passenger side of the metal transmission oil pan. Now look at the very front of that section of the transmission oil pan and follow that ''line of sight'' until you reach the bottom of the aluminum motor (''oil pan''). The oil drain plug is right there, with it's head facing towards the transmission oil pan.

The drain plug (on a 2005 Sunfire) requires a 15mm wrench/socket; and has a built in rubber seal, which should be lubricated with oil before tightening.

FIRST OF ALL YOU NEED 4.0 QUARTS OF OIL FOR 2.2L 2.3L AND 2.4L OHC ENGINES AND THE 2.2L OHC USES 5.0 QUARTS WITH NEW OIL FILTER.TO GET START YOU NEED A FILTER WRENCH,DRAIN PAN, RUBBER GLOVES WHICH PROTECT HANDS FROM OIL.

I assume this is an automatic transmission, you didn't say.
There is no dip stick on the transmission any longer.
You will have to go under the car to check. You may want to go to your local instant oil change and have them check the level.
If you feel you want to check it, here is a description of the location and process.

Make certain the vehicle remains level while checking the fluid.
Located just above the top sealing flange of the transmission oil pan you will find a threaded plug. Remove the plug and see if transmission fluid drips out of the hole. If so, the fluid level is correct. If not, remove the red fill cap on top of the transmission, driver side. Add fluid to the transmission until fluid dribbles out of hole.
Replace and tighten the plug.
Good luck.
