Search for review of oil filters. (See link below) Somebody disassembled a couple hundred and reviewed every fine detail and spec on the filters. One of the top was WIX, so I bought a dozen for my truck. IIRC another was Baldwin. Great Thread. Read the summary section to know top good filters and top bad filters (some premium labled ones to boot). Biggest concern was really the quality of the drainback valve.
Overall, I think best oil (But Not Conventional) is Mobil 1 5W30 for most of us, Amsoil in same tier of quality. I'm using Mobil1 at first change done at 3500 miles (just prior to major highway trip). I have no concerns of delayed breakin period. Not to be foolish or disrespectful to anyone elses opinion or what there buddy told them who really knows engines, but - Big Corps like Mobil etc. spend lots of money with real engineers to invent this stuff and prove/disprove qualities of a product before selling it. Mobile 1 did not build its rep over the years by ruining engines. Many Oil Analysis here back that up.
CONVENTIONAL OIL: If JetTech says Chevron Supreme does good, trust what he says. He backs his statements as well as anyone, even if I disagree with some piddly statement. He does great research. Buy Chevron Supreme and a WIX Filter and sleep well at night.
I do my own LOF, cost about $42. If coolant system ever blows a hose, I have no worries of engine damage as Synthetic will not fail to protect engine. this is the best MOD any of us can make to any vehicle.
Life in general - Learn the rules and why they are the rule, then learn when you can break the rules to be innovative/creative without harm. Dont make your rules by a few exceptions and ignoring the obvious truths.
