If you count not going by the MM in my wife's Honda I have about 10% oil life remaining. Probably close to 5k maybe 6k on the oil and it was changed in March. Running Amsoil SS so plan on changing next march which might put 7500 to 10k on the oil. Car is split between 2 - 3 days a week highway and 2 - 3 days a week local. I figure by March I will be closer to -15% life remaining. Since the car has 115k miles on it I don't feel so bad.
