Every morning i drive to school and i let it warm up.. but as soon as i start the car it makes a nocking type ticking noise.. and it DOESNT go away i dont feel and performance decrease its just that the noise is driving me crazy it sounds like im driving a deisal TRUCK!!... is there any thing i can add in the oil like the lucas oil stabilizer or something to make it go away.. i have 106,000 miles on the car...
