2007 Honda Civic - 1.8L 4 cylinder engine
OCI: 7,525 miles over 9.5 months
OLM: 5%
Typical commute is only 6 miles each way, highway trips filled in most of the rest of the mileage. My driving style is very gentle. The car rarely goes above 3k rpm.
I did the UOA mostly to see how well Honda's OLM worked. I estimate it was less than 100 miles from reading 0% when I changed the oil. Results look reasonable to my untrained eye. TBN of 1.4 is acceptable, and wear metals are expected to be high for a new engine.
BLACKSTONE: Don't be alarmed by all the highlighted numbers. We expect to find most anything in the first few samples from a new engine. The excess wear metals are from new parts breaking-in, while silicon is from sand-casted parts and sealers used when assembling your engine. Both should improve with subsequent oil changes. Universal averages are based on an oil run of ~5,200 miles. With a few more oil changes your engine should look that good, if not better. The TBN read 1.4 so you had some, but not much, active additive left. 1.0 is low.
