Engine Mechanical problem
2005 Pontiac Grand Prix 6 cyl Two Wheel Drive Automatic 36000 miles
The car "uses" oil, as stated by the dealer. No oil seen in engine, and no oil in driveway where it's parked. I've had the car in twice for oil consumption tests, since GM indicates that it's "acceptable" to "use" 1 quart of oil for 2,000 miles. My question is, how much oil must be lost before the "low oil level" light appears? I'm taking the car in to the dealer tomorrow for the 4th oil consumption test (it's every 500 miles and it's now 2,000 miles) and I checked the dipstick today and the oil level is below the 5th hole on the dipstick.
