Okay ..I began to wonder if I was going to see any results at all. The worst thing, for me, would be to have nothing to report.
Anyway, after just getting a brief 5psid reading with a 4/2 20w-50/5w-20 blend ..I began to think that my filter was ruptured/breached. Since I have a perpetual oil change (another signiture Gary Allan/Rube Goldberg installation - more later) ..I had cause to top up with 4 quarts of PZ LL 15w-40. The temps were still subfreezing this morning ..as they were yesterday.
I took off the small filter and replaced it with a 9k old filter that was sent to me by Ugly3 about 9 months ago. Here's what I got at the first start of the day. The temp was @ 28F with an overnight low of 22F locally. This was with revving the engine fairly high.
About 30 sec later (at idle)
after about a minute
At 60 mph after my 3/4 mile distance to the four lane.
The PSID doesn't react in a linear manner. It reaches a peak ..and decays from there.
Ugly3: You could have drained that filter a few more hours before stuffing it in the plastic bag(s).
I want to add that I did see some elevation in PSID from a standing start to speed. This was at about 140F oil temp. The only way to describe it was "surge" ..since I could not sustain it even with leaving the van in low gear. The most I could get out of it at about 40 mph in 1st gear was around 3-4 PSID.
For all practical purposes ..I've got to say that the bypass valve is only to protect the media during start up ..and that it does it very well over a very long duration.
Those are the primary observations at this time anyway
Your comments, as always, are welcome.
