BLACKSTONE'S COMMENTS ON MY 2003 HYUNDAI SONATA 2.7L V6: [My comments in square brackets]
RAY H: Another nice improvement in wear. If these metals get any lower, we'll be looking at virgin oil! This oil was run 3,000 miles, but it could have run much longer, considering the low wear your Hyundai is producing. The oil was in good shape physically, containing no moisture, fuel, or coolant. The viscosity was mildly low, but since it's not being caused by a contaminant, it's okay. Insolubles (oil oxidation due to heat, use and blow-by) were normal at 0.3%, showing good oil filtration and complete combustion. Great engine! Try 4,500 miles next time.
[Though the oil was only in use 3,000 miles, the time duration was nearly 9 months. I labled it "Mystery" oil because the only similarity between all five quarts was the 10W-30 viscosity range. The content consisted of bottles (capped) and partial bottles discovered in one of my all too rare periods of obsessive compulsive garage cleaning attacks. The criteria for use was five-fold: If the contents neither left me gasping for breath, caused skin eruptions, showed observable nasties in the bottom of the bottle, demonstrated threatening or obscene gestures, nor burst into flame upon exposure to air, in it went. API service categories ranged from SH - SL. As usual, any and all comments invited, regardless how stupid or irrelevant...
