If you had no start-up noise and after you changed the brand of oil and filter, you made noise, then you already know the answer. Its just 2 variables and not rocket science.
Either your oil suxx or your filter suxx. Was the filter sourced online or purchased at a local store? If online, I'd purchase a locally sourced filter now.
So, keep the oil, change out the filter, and top off the oil. Post the results. Try the Napa Platinum or Purolator Boss.
Concerning the oil, and a possibly (re)tired oil pump, you might have an issue. Do you expect the same from a 5w30 that is 9.5cst to another at 12cst?
Without a VOA/UOA of the old brand oil and the new brand oil, you won't know how temperamental your engine will be with a different oil/filter combo.
This certified sludge monster is one of those engines that I won't install conventional oil.
And, if in budget, get the final rev valvecover/pcv upgrades.
Since its a certified sludge monster, and since the 7500 mile oil change interval dropped to 5000 miles because of the settled class action lawsuit, I would even consider the FL400s/3600/1516 sized filters.
I haven't heard any startup noises from the XG3614 on the 1mz/3mz engines I've installed it in. If the engine is that picky, a problem is developing.
