windage tray question

FWIW, you don't have run 8 qts. in an 8 qt. pan. Less oil helps keep the level away from the crank windage. I only go up to 7,000, but I run 5 qts. with a scraper and Amsoil synthetics. I do get a little fluctuation, but never a bearing problem. Current engine has about 4 seasons on it but is getting replaced soon just to be safe.
