I just changed oil and add this. From cold start I can hear tapping noise. I put in a just over 100 miles and started running rough at start-up. Once the engine runs for a while no more tapping noise. I think this product is too thick. I used 5w30 full synthetic with this on my 98 Expedition with 163k miles.
