I'm someone who did 3,000 mile oil changes (conventional oil/cheap oil filter) for decades. I never even considered synthetic oil until I bought my 2011 Forester in 2013 (ten years ago). 0W-20 was just becoming the norm for many vehicles at the time, & it made me re-evaluate things somewhat.
I find some comfort knowing Steve's plastic car (2014 Mirage) went 307,000 miles (before he sold it) without issue. Since he was granted free oil changes for most of those miles, I think he was good about having it done every 5,000 miles (5W-30 conventional oil/cheap oil filter done by a Cadillac dealership).
If given the choice -
I would pick a cheaper Super Tech full synthetic oil/low to mid-grade oil filter changed every 5,000 miles over a top of the line oil & filter brand changed every 10,000 miles.
