It's been a long time since I did a UOA on this engine. Pickup has 138k miles on it, almost exactly 9k miles on the oil (Schaeffer # 9004, 5W20).
I've never seen UOA numbers anywhere near this low from a J35 in one of these pickups, but I also don't recall seeing many (any?) with >135k miles on...
Is that not the product which appears in the JALOS certification (or registration) list, here:

?
Whether or no, JALOS has all registered / certified oils on their website. That’s how one determines whether a particular oil marketer generated the...
I've never been especially impressed with the filtration efficiency of the Amsoil filters. They may be constructed extremely well, IDK, but the pre-buyout Fram Ultras were VASTLY better-filtering products. My understanding is that the Ultras changed media and _may_ no longer filter anywhere near...
Denso’s presentation on the topic of their factory-fitted parts vs their dealer service parts vs their aftermarket parts quality has been posted here before. Factory-fitted parts are best. Dealer service parts are somewhat less, and aftermarket are less still. “Less” means lower quality or...
Soot is an ages-old Diesel engine issue. As was said, centrifugal separators are how it is removed from those lubes. One could consider employing the same on a GDI engine. I seriously doubt the cost-benefit is there, and the soot particles are likely not the same general size range.
I am...
I’m only aware of field data, not journal publications, but perhaps I should re-phrase my previous question slightly: Is the thought that the HPL product will reduce fuel dilution as demonstrated by GC in fleet field data, or is it simply believed to better mitigate the effects of the same...
I’m familiar with the opposing effects of oxidative thickening and permanent shear or fuel dilution. When I referred to my fleet data, I meant the fuel content as measured via GC.
S&B would be my choice if they had one for any of my factory airboxes. They filter much better than AEM, AFE, or anything I know of other than the ultra-best AC Delcos. They even offer choice of serviceable oiled cotton or disposable dry.
What I heard from that segment was:
Cylinder wall finish, oil control ring tension (and design), and lube oil viscosity need to be matched as a system in order to minimize oil consumption.
My first thought question was:
Viscosity as measured how? The ring-cylinder interface is about the...
Again, not relevant either to the engine I presented or to the point of whether higher AKI allows higher output in a specific setting that offers improved fuel efficiency.
