I took my 97 4 cyl (5SFE) Camry to the dealer today for various services and had them change the oil using my M1 5W30 HM. The tech overfilled by about 1/2 quart. I know questions on the dangers of overfilling have been posed here many times including by me. I can't remember anyone asking about 1/2 qt over. Is that much overfill a cause for concern in a car that calls for 3.7 qts?
