This is oil from my bucket. The car has 191k miles on it, the engine has maybe 85k ish. It's a used engine the previous owner installed after overheating the original.
I just posed a, "virgin," sample of this oil as well. Granted the oil properties of the bucket (I have two now) is ever changing.
I've been trying to follow the severe service maintenance schedule of 3 months/3k miles as I barely put 10 miles a day on the car. I'm a short tripper. I just changed out the K&N cold air intake back to the stock intake and air box setup with a WIX filter. I'm using the Wix Pro Tec filters which are sold in boxes of 12 at work, it's the cheapest filter I can buy.
I might stretch this next oil change out to 1 year/5k miles just to see how it holds up. I've spent way more on oil analysis than I have on actually changing the oil.
