Fecomosis, You ask me why am I here? I am here to bask in the infinite wisdom of car gods such as yourself. You say I don't know jack about cars, however you are the nimrod running an expensive 15w40 motor oil in a 10 year old vehicle, who also believs that switching to a lower viscosity oil might make the ticking noise dissappear. I was simply stating that royal purple is a rather expensive choice for motor oil on a stock minivan. Believe me when I say this FUCK FACE, I have pooped out more information about cars than you will ever learn in wasted lifetime.
