Typical 5,000 mile automatic maintenance reminder on this generation Lexus. The owner doesn't plan to extend. The car sees lots of short trips to work and back daily.
I poured in the same QSUD but in 10w30 flavor for the remainder of summer here in Florida. Will not be sampling anymore. Engine is healthy (which was the reason for the sample to begin with) and the OCI is easily achievable even with conventional oil if needed but will stick with synthetic because IT'S CHEAP!!
Overall I'm not too impressed with the QSUD. TBN seems low for "only" 5,000 miles.
