Clear tank test

Test involve many runs with changes to sump design and oil pumps. Videos were taken. Dailey's pump with the air-oil separator made a huge improvement. Sump changes were also important as was bottom end breathing. I measured over a 5% reduction in the oil density early on before improvements. Cold oil is the worst, but in all cases the air-oil separator provided the best quality oil. I forward a couple videos to Dailey who uses them on his website to show the effectiveness of his air-oil separator.
