well, i changed the oil in the mirage sunday with new 5w30 valvoline like i usually use, and changed the filter as well. the oil that came out wasnt even that bad. then again, i have to add 2qt every 3 weeks or so. the old oil and filter had ~15K miles on it. i havent changed it since last april when i put the car on the road. i should have left it alone. the motor has a prominent rod knock at idle now. what do i do? fuck. drive it till it blows up! 194Kmiles, y0!
