This is anecdotal but it happened to me. After using Kendall and 76 Super synthetic blend 5w-30 for more than 10 oil changes, at 72K miles on my M35 I switched to all QSUD using another new Nissan OEM oil filter as used since new. Prior to the change, there was zero usage between 5K mile changes. During the first 1,000 miles using QSUD, it used half a quart. Next OC I switched back to a blend of QSUD and QSGB and usage returned to zero.
