i am past 0% for oil change for my rdx. It was at 5% and next thing I knew- i lookd down and it was negative. I'm at negative 27. I have an appointment to get my oil change on Saturday. I drive about 40 miles round trip to work - so will basically put 120-130 more miles on it before the oil change. Should I not drive the car? will this hurt my engine? Thank you very much for any help.
