Recently changed the oil by myself, it was the first i do this in a car lol and came up as dark a soy sauce, and even worse... i added some valvoline synpower full synthetic 5w30, the engine sounds better and idles smoother. However the pinging noise seems to be still in there but now after the engine is warm. Any ideas? i am guessing it could probably need a new coolant... at this stage i feel like the dealer was ripping me off
