I've had this oil for 2000 miles in my '96 2.8 V6 12v Audi engine. Engine runs and sounds great with it. The first 1k miles I didn't notice any oil consumption. All of a sudden I was half a quart low (I check the oil ca every 500 miles). I'm not having any oil leak at this time (The dang valley pan gasket is "sweating," but it's not dripping), so the sudden oil consumption took me a tad by surprise. I think there are three expanations: 1. I've been spending a tad more time a redline than usually, and of course the engine burns then more oil. 2. The valve stem seals aren't the freshest in this 8 year old car, and maybe they are about to give up the ghost (no smoke yet). 3. The oil is doing something weird. It also could be a combination of issues.
