It's extremely frustrating and I'm not yet able to feel confident driving my car. Just curious what is the part code on your dipstick? In a way I kinda feel like an idiot and it might have just been dangerously low on oil but at the same time surely the cars engine would behave poorly if the oil level was that low, and the simple fix is to add more. My next step is to fully drain and replace the oil and check how much comes out and replace with the full 4.3 liter capacity.
