I am aware of the issue of fuel dilution in CRV. This is a Sienna. The remedy is a slightly shorter OCI. And a flashpoint that creeps back up towards threshhold. Severe service. 5k mile OCI.I mean, we have a lawsuit by the Chinese government against Honda for this very problem, it's a REAL problem (fuel dilution).
That's wonderful, but that doesn't address the issue about this level of fuel dilution.
Other than perhaps crappier than normal ring seal due to seating, what are you implying the relationship is between the 265F flashpoint and break-in?
PPM metals in a UOA are not a substitute for tear-downs, which has been discussed many, MANY times on here.
OK, but unless you also have a 265F flashpoint I'm unsure what you think your long OCI is proving here? Are you also going to perform some tear-downs for us?
You might recall positing concerns in my Insight about oxidative thickening. OCIs were well over 10k miles. With the 0W8 of course.
In my case, the plan is 500k miles and beyond. Sorry. No tear down.
As a side note, I did almost purchase precisely the same vehicle as OP. Basic hypermiling would have been in the cards. The second row seats are not easily removed. That swayed me away in part.
