Leaking again at 10,000 miles -- will take back to dealer. "Jerry" service manager says Buick has a problem with this engine. . . now it is my problem. . .going to take this to the next level.

Upon physically checking oil level in my 2010 Buick Lucerne 3.9L, V6 engine, with 25% oil life displyed on instrument panel between oil changes, none showed up on stick. Added a quart and level went to approximately 1/8 of an inch on stick...added another and it went to the mark just below the full mark. Took car to local dealer where car was purchased for an oil consumption test. I was told that there is an indication of an oil leak, but I assured the technician that there was no sign of oil leak on my cement garage floor. Changed oil and returned after 1,047 miles. Oil consuption test revealed .25/quart used and engine was again tested for an oil leak. Dye was added to oil and leak was observed at front of engine with a black light while engine was running. Crankshaft seal was replaced and was told that the problem was resolved. We shall see! Surely hope this new engine doesn't burn 2 quarts of oil in 4500 miles!

Noticed the oil leaking first time around 4000 miles. Had the crankshaft seal replaced. Oil continued to leak. Can in to dealer for repair again. Seemed to take care of the problem. After oil change at around 18000 miles, oil is dripping again! Will be back to the dealer service department again this week.
