The question came to mind, as a result of the noise I got at 20F start-up, when I switched to the Mobil 1 filter. Since that sound was virtually identical to the "dry start" sound a newly installed, empty filter causes, I thought perhaps they were related. Therefore I was just wondering if some convergence of cold temperature, different psi specs( on the Mobil 1) Bypass valve or ADBV could have caused a dry start state in my car?
If the filter is orientated in such a way where a leaking ADBV would cause all the oil to leak out of the oil filter after sitting for a long time, then YES, at startup the filter would basically be empty ... just like if you just installed a brand new one during an oil change and then fired up the engine. "Dry start" scenario ahoy.
Of course, the colder the oil temp, the more "cold start" flow issues will appear depending on the oil viscosity and oil filter being used.
Start an engine at -25 F with conventional 10W-30, and then with full synthetic 10W-30 and I’d bet you’ll hear a difference in engine noises at startup. Then do the same thing with one oil filter that has an 8 psi BPV setting, and again with one that has a 23 psi BPV setting. You can see the trend that I’m striving for here. Using conventional 10W-30 and a filter BPV setting of 23 psi at a -25 F startup probably would be a good thing.
