I was going through some of my GM Tech Link issues and found some information that you may find useful.
Checking Oil Level:
The engine must be warmed up. Cold oil will not give a correct oil level reading. After the engine has been warmed up to at least 175 degrees, shut the engine off. Wait 5 minutes but not more than 20 minutes to allow the oil to drain and settle. Pull the oil level indicator from the reservoir and wipe it clean and then reinstall it. Pull the indicator and note the oil level on the crosshatched area. An oil level within the crosshatched area is normal. If the oil level is below the crosshatched area, add 1 Qt of 5W-30 Mobil 1 synthetic oil through the oil reservoil fill cap and take another reading. Do not overfill the reservoir as this may result in excessive oil consumption. Oil levels above the crosshatched area may degrade lubrication system performance.
Oil Change Procedure:
Remove the 2 drain plugs from the engine oil pan. One is located on the left side of the oil pan near the oil filter. This plug drains the small amount of residual oil from the engine oil pan, approximately 1 Qt. The other drain plug is located on the front of the oil pan. This plug drains the external reservoir and hose assembly, also remove the oil filter. Once the oil has been drained from the engine and reservoir, replace the oil filter with a new PF-48 oil filter. Replace both oil drain plugs and tighten to 18 lb. ft. Remove the oil fill cap on top of the dry sump reservoir and fill with oil. The total service fill with a new filter is 8 Qts of 5W-30 Mobil 1 synthetic engine oil. Replace the oil fill cap and start the engine and let it idle for at least 15 seconds to circulate the fresh oil. Check the oil level as previously described and check for leaks.
Important!
There is a cap on the right valve cover under the decorative cover. Attempting to remove this cap can break the retaining tabs requiring the removal of the valve cover to remove the broken pieces. Under no circumstances should you attempt to fill the engine oil system through this cap.
