Looks like I have some catching up to do.
I hate this generation of civics.
That being said 10k on this oil on the conservative side
and 12k on the liberal.
Since I hate this generation i would do 12k
I love my civic! Haven't driven any others but I love mine! Why go back to 12k if 14k was fine?
You didnt get a TBN reading?
With TBN down to 1.7 on my previous run of 10k I thought TAN would be more valuable. The NAPA kit I used included TBN but I added a note requesting TAN instead and they did it for me.
Wow thanks for posting. I have a large stash of Trop Artic and I would have said these kind of OCI's were way too long for it. Still longer than I'd want to run it but I need to rethink my evaluation of it.
Thanks for posting this OP, we don't have near enough UOA's of everyday Joe kind of oils here IMO.
The owners manual calls for 10k OCI under normal conditions so this is a 40% extension. YMMV.
I think there are several reasons we don't see many everyday Joe oils being tested. For instance, those here who buy the cheaper oil don't want to turn around and spend money on a UOA. Also, those willing to chase deals and/or mess with MIR's can get synthetics for less than conventional. Right now I'm running Pennzoil Ultra purchased on clearance from WM for $21, subtract the $10 MIR from Pennzoil and I paid $11 for 5 qts. Back to UOA's, regarding Trop Artic, it may be an availability issue because this is not the easiest oil to find. But I agree with you, it is nice to know what the cheaper oils can do so we can make informed decisions about how much extra value comes from the higher dollar oils.
The sodium and potassium levels show that there could be a little coolant getting into the oil.
Blackstone doesn't give oxidation numbers but it looks as though a little oxidative thickening may have begun.
Not sure what's up with the non-linear increase in copper.
Could be bearing wear, although lead is low, or could just be a lab error or a fluke.
I have to say that this looks really good, though.
Dave Newton should be proud of you.
I also wonder about the sodium and potassium, I will be keeping an out out for anything unusual.
Phillips 66 claims a viscosity of 8.4 cSt so there may be a little thickening but nothing to bad.
The copper *may* be explained by the oil filter situation but I would have expected iron to climb along with it.
I like to think Dave would be proud of me.
