COP/Honda 0w-20, 6,185 miles, 11' CRV

[Cardiobuck]

OK, 2nd sample from my CRV just resulted. This is using the COP made for Honda 0w-20 with OEM filter. This is 90% city/10% hwy. Most trips are ~10-20 minutes in length. MM was at 15%. Due to elevated silicon on the prior sample I replaced the air filter in the first few weeks of this run--with an OEM filter. I am disappointed to see silicon even higher this time with a run of similar length.
Also concerned about the amount of fuel. Is fuel like this expected when running 90% city miles?
I would appreciate feedback regarding the silicon increase as well.

Looks good! Is this the full synthetic or synthetic blend 0w20?

 

[Cardiobuck]

It is the full synthetic.

Change you AF at the end of the oci:Not the beginning of the oci.

All looks good. If you didn't get the oil up to full operating temps when you drained the oil, the fuel isn't surprising.

Regarding the silicone, I think you're "killing it with kindness". It wasn't really high to begin with, but opening the air box and installing a new (less efficient) filter isn't going to help. I'd just leave the air box alone--as the filter gets older, it will offer better filtration.

Dirty filters, filter better.

I ran the vehicle for 25 minutes including a small highway loop prior to draining it so it should have been up to full temperature (outside temp was about 40F). I do this per Blackstone recommendation prior to taking a sample.

You may be right about the new air filter as I also saw an increased silicon reading in my other vehicle after changing it.

The risk of dislodging dirt is why it was recommended to change near the end of oil change.
The fuel issue you may want to bring to the dealers attention in case its a warranty issue. May be a faulty or dirty injectors.

The oil looks a lot like Motorcraft, not surprising! It held up well despite the fuel, fuel and filtration are your issues wear is fine IMO.

Interesting to see high silicon on another late-model Honda. The Filtech housing/filter doesn't seem to live up to Honda's QA standards.

Search my username for my UOA threads, you'll see I had the same issue with the factory filter in my Civic. I haven't written up my thoughts on the best filter yet, but I think I traced the leak to the perimeter seals on the OEM Filtech filter.

Aftermarket filters varied substantially in their seals. I ended up with a NAPA select (silver) because it had the thickest seals which were also stiffer than many, indicating the tightest fit and greatest installed preload. The select filter was substantially different from the Napa Gold filter which had softer, thinner seals, which also showed substantial production irregularities.

I also used the Honda Ultimate 0w20 for the first fill in my Civic and it held up well. Yours seems pretty thin at 7.02 cSt, though mine was pretty thin at 7.23. There aren't that many UOAs on this oil or its Kendall cousin, so it's hard to generalize on shear stability.

Other than the Si, the report looks good.
