There's an acdelco filter in there right now since I had the oil changed at the dealer. The OLM is reading around 40% right now so next oil change, I'll use whatever full syn 5w30 is cheapest at walmart (M1 has been cheap at $22 recently and their 5W30 is A5/B5 spec) and I'll try one of those other filters. Probably the Fram Ultra because it'll save me a trip to another store.

If this app is for a GM, be aware many GM engines are 'sensitive' to Fram Ultras and may squak when cold-started. Both of my GMs did. Fram Tough Guards were fine thou.
All you need for adequate filtering and still equal to a AC Delco (without the squaks), is a Fram Extra Guard with the new silicone ADBV. A best bang for your dollar spent.
In 2nd Place is the cheaper K&N, not K&N Gold. I'm really impressed with it's quality and quietness......so far - 3K of a 6K OCI. I paid $4.99 for that K&N online and I never shop EBay 2nds

Something is happening to cause occasional dry starts. From the reading I've done here on bitog regarding ADBVs, Seems that an ADBV will prevent oil from leaking down from the passages above the oil filter. Additionally, the AcDelco filter(s) for this application all have an adbv so I'm going to stick with filters that have an adbv. If I can find one with the superior, silicone construction, I'm going to give it a try because the AcDelco filter isn't performing well for me.

That's right, even though a filter is mounted verticle with the base up, the ADBV will prevent any oil in the galleries located above the filter from leaking down. People saying that a vertical mounted base up filter doesn't need an ADBV keep spreading that misconception. Some engines are more likely to leak down oil when shut off, so using a filter with an ADBV can't hurt regardless of filter mourning location.

OP - "Something is happening to cause occasional dry starts. "
I agree something is happening.
There are a lot of variables at play:
The hardness of the ADBV
The viscosity of the oil when you shut the engine down.
The viscosity of the oil when you start the engine up.
The condition of the oil and the filter.
The condition of the hydraulic valve lifters.
And the list could be more.
I conducted a small experiment to see if the filter was leaking down.
Usual oil change sequence
1. After a long hot run
2. Shut the engine off
3. Spin the oil filter off without delay
4. Observe plenty of oil leaked out and left a mess to clean up.
5. Result oil filter ADBV held oil for 5 minutes.
Alternate oil change sequence
1. After a long hot run
2. Shut the engine off
3. Go to bed and sleep well.
4. Do not start the engine.
5. Spin off the filter carefully.
4. Observe only a minuscule amount of oil came out from the galleries above the filter.
5. Result oil filter ADBV did not hold oil over night.
If you pull the filter cold, you can confirm whether the filter is guilty or not. I have caught WIX 51372 with leaky ADBV this way. It has a silicone ADBV.
The time to check like this is after you start noticing noise on startup.
Anyway, my 2 cents.
