Nothing very exciting here. A friends car that I maintain and this is its first UOA. It's the 1.8 2ZR-FE motor. It has had a steady diet of ASM 0W20 and Wix filters since factory fill was drained at about 4k miles. The car sees mostly city and secondary roads. The computer reported average speed 29 mph. The "Service" light usually comes on by 4k miles indicating time for oil change. I just reset it and continue running the ASM 0W20 about 6K miles. Oil consumption very slight and no top off oil added. This is an OAI report out of the Indianapolis lab. Current fill is SSO 0W30. I plan to run it 10K miles. Air filter was changed for the first time with this last oil change. The new air filter is a Wix.
