What kind of oil filter/air filter are you using (and did you use for the test)
The oil filter is a Pure One, but on the 2.4 it is a tiny little thing. I might throw another one in there with some make-up oil before the change.
Air filtration is standard paper (I hate K&N type filters) and the plumbing is fine. The silicon is no surprise. First of all its well within the tolerance of a cheap oil analysis, but mainly because, well, welcome to Texas in the depths of the worst drought since the 50s. Dust is pretty bad this year. No, dust is HORRIBLE this year. Go back and look at the UOA for my 1966 440 from last month- high Si (even allowing for recent gasket work). Even my Jeep from much earlier in the spring was way on the high side. I'll be buying every vehicle I own a new air filter, regardless of miles on it, as soon as the sky remembers how to rain.

Maybe. Not much I can do about the weather and dust to get the Si down, other than keep the intake system sealed up tight. Personally I think the TBN is probably just a matter of AFE not being the best pick for a really long drain interval- I'm not really sure how Silicon and insolubles would affect TBN unless some of the insoubles were acidic. Old deposits still dissolving? This is the second oil fill since we've owned the car.

TBN is fine: low initial base give better wear numbers and engine performance on standard interval OCI. You'll never see high TBN in a race engine. This aint winter, this aint a EP oil looks [censored] good (better if we get our rebate sometime this YEAR!)

Quick update- I put on a new filter and enough make-up oil to compensate, and I'll run this fill a while longer. The filter that was on the engine was actually not a PureOne, it was a NAPA Gold (Wix). All the oil fumes must be affecting my memory ;-) This time I did use a PureOne, and got the longer type recommended for the Turbo 2.4. Its the same diameter, but twice as long as the one for the non-turbo.

TBN could be an error,but it's still almost 3,id go another 2,000+ miles with a 3,may have good retention by now,who knows.
i do 7k on this oil....

I need someone to tell me how 10.6Cst reads more like a 10w-30 when even the VI wasn't tested ..and wouldn't show the CCS/MRV numbers anyway
That is, I don't get the Blackstone comment.
This stuff is allegedly 11.0 cSt in the bottle. The starting TBN is only 8.5 instead of the 10.x that most of us are used to.
As you suggested, this may not be a candidate as an extended drain oil.
XOM
Then again, it's early.

Gary, you are right. Such Blackstone comments on viscosity grade based on only testing at 100C are both common and ignorant.
*nevermind* already covered...

Good thing he didn't send them German Castrol 0W-30...

I'm relatively new at analysis reading, and that comment rang my bovine excrement detector bell too. I can only assume that they're waving their hands and talking to us like children and propagating the outdated ASSumption that "typical" 10w30s are a little thicker than "typical" 0w30s even at 100C. Its just a silly comment, though- an ideal 0w30 and 10w30 will be identical at 100C. Of course nothing's ideal, but a lot of today's oils come darn close to it in that regard anyway.

Based on everything XOM says about that oil, I'd never expect to run it more than 6k miles. The whole world does not revolve around extended drain intervals... at least not my world anyway. If I still racked up 30k miles per year like I did back in the 80s, then yes extended drains would be my goal (heck I accidentally ran a few 15k mile intervals back then, even on those old-tech oils, and the old 318 survived just fine and in fact is still going). But only putting 10k per year on the newer cars? Nah.
