Yeah I’m figuring he shot me a line of dodo. MC 5w30 is probably better than 5w20 here in NC . But it was just the Ford changed the spec on the 3.3 engine oil comment. And I can’t find a documented spec on this so called change. Thanks for the reply’s. Hell I wish it was changed. My wife edge 2.0 eco is MC 5w30 syn blend. One oil for ALL !!!!!!
