Honda factory fill 5W20, 7525 mi, 2007 Civic 1.8L

[fanamingo]

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.

silicon is sky high, but like mentioned, after several oci's things will settle down and you will have a nice wearing motor

Wow, those are unusually high break-in numbers compared to what I'm used to seeing from Honda and Toyota. Nevertheless, Blackstone is probably right. I would not worry a bit unless your next UOA was similar.

Perfectly fine. OLM's are very accurate IMO. Tbn of 1.4 is about right on target with the 5% figure for the OLM. Fe will drop in time.

The idea is to get the wear metals out of your engine. I would not go more than 5k next time. But that's just me.

 

[buster]

True, but you'd have to do a particle size or ferrography to really know. If the particles are very small, it's nothing to be worried about. 37 ppm is not high for break-in. The engineers that determine the drain intervals use engine tear downs to know what is the correct drain interval. Oil analysis is far from being a perfect science.

 

[glennc]

I agree. If you are worried about abrasive wear from metals, you would need to get much worse than this. All the big stuff is pretty much in the filter.
