I had been flying with a CFI for 2 hours before leaving a CPPP [Cirrus Pilot Proficiency Program] for home. I checked the oil level before the dual flight. I thought it read five quarts. I checked the oil level before take off for the flight home. I thought I read five quarts on the stick. While idling and waiting for take off an oil warning light lit up. I found low pressure on the oil pressure gauge and a high oil temp reading. I notified ground control of the problem taxied back to the ramp and shut down. Checked the oil level again. I again thought it read five quarts. No evidence of oil loss on the belly or under the cowl. I added three quarts of oil. The stick then read six quarts. Upon restart the oil pressure and temp were normal. I need to check the oil level better. This oil stick does not show a good level when the engine has been running. Adding a quart has NO downside. I need to do a better preflight and look very closely at the oil dipstick.
SR20 pilot reports low oil pressure while waiting for takeoff clearance and taxis back to the ramp. Dip stick oil quantity indicates five quarts as it had previously. Three quarts are added and the dip stick indicates six quarts and engine run up indicates normal pressure.
