A VOA tells you pretty much nothing about an oil's goodness and is radically overblown by most. It's pretty useless aside from indication of a formulation change and general ideas about how they got from A to B. I hope the owner of my next used car cares more than average.

Do you have any interest in DIY sauerkraut? Fermenting has been my favorite new hobby within the past year. Supports keto well.

They've learned that they shouldn't make more poorly crafted vehicles than their secondary manufacturing centers (dealer service departments) can support.

Present post count of 31, all but 3 complaints about rebate status. That's a 90% dissatisfaction ratio. The balance are speculation on a boutique oil based on lubrizol spider chart. He fits right in on bitog.

Be relieved, I slept fine last night. The engines in my driveway are still not known for wear related longevity issues and hammering absolutes out of generalizations over a few tenths of viscosity or hths is still pointless. I haven’t looked but I’ll bet $5 none of my vehicles have a “for...

If all modern engine failures are traceable back to metallurgy, then the quest for viscosity as a wear cure falls apart though.

Or make the design with some margin by increasing contact area. Reduces load. If your design doesn't allow for manufacturing variability, the design is the problem. I used to work in a development group. We had plenty of great designs of things that couldn't be made. Design or manufacturing...

Whatever KV100 follows that magical HTHS. Context is - those are the completely independent parameters that matter to bitog oil buyers. Since they're all independent, no compromises are necessary. They can all be met simultaneously. Right?

Fragile valvetrain for which the manufacturer has prescribed 0w-40. Working a groove sounds oddly like wearing a groove. But to reiterate post 31, I've never had an engine with lubricated part failure (or a model known to be susceptible to lubricated part failure) so chasing tenths on HTHS and...

post 83 was only 9 minutes ago and you already forgot what you said?

Now you're putting words in my mouth. See post 31. But if you want to take your generalization to the edge of the graph and beyond, you (as usually) don't need anyone else's help.

Highest HTHS 0w or 5w winter rating <6% NOACK shear stability zddp and moly to taste LSPI tested $22/jug at walmart And no compromizes. You've found bitog's perfect oil.

Yet, two experts in this thread have said increases in viscosity/hths only decrease wear.

And what you got was commentary on formulation and the contribution of VII to volatility, and even the tradeoff between different VIIs used. Even the lowest volatility 0w-40 will be higher than the lowest 5w-20. Therein lies the inherent compromise for only caring about HTHS holy grail. The...

These. Except for that pesky association with wide viscosity spreads and the requisite "formulation" to achieve them. Now that I've lead you full circle, perhaps this thread of yours will refresh your memory...
