I have a 2017 mirage (30,000 miles) and have been noticing occasional knocking in very cold weather (Buffalo, ny). Thought it might have been the oil filter I was using (purolator boss), then switched to a wix and still had the same problem. So I changed the oil (Valvoline 0W-20) and put a Mitsu filter on, after 1500 miles it started to knock again occasionally again.
So now i am thinking its the 0W-20 oil that is the culprit. My thoughts are when the oil gets some miles on it and thins out that's when the knock starts. MY suspicion is that the oil gets thinner and either leaks out of the ADB valve in the oil filter back into the engine OR its just too thin to adhere to the engine components.
I would greatly appreciate any feed back cookiemonster!
