When I was 17,1992, my local Mobil gas station,now gone,was my go to place. I had a 1983/84 buck century my dad gave me. The mechanic,pricey,john, was older school.he understood mechanics,but didnt understand sensors,so I was told by another mechanic he knew him,later in life. A mechanic thier, kinda looked like a Caucasian jimmy hendrix, red bushy Hendrix like hair..I asked about oil filters one day.he told me, he didn't like frams.cardboard endcaos.might leak. Best filter was oem,dealer/factory. He said, as long as you change your oil and filter every 3,000 months your good I don't know if he also said 3 month.my dad did it every 6 months. We had under 3,000 miles by then.
The mechanic also said,the efficiency didn't matter as long as you follow your oil change,the engine car will last .
So! In my oil changes,taking filters apart.I find,it does matter. Oil was black but not as thick or black with wix,Napa gold,pureone. 3,700 miles in 4 month windows.but with gram oranges,supertech,car quest blue,oil was thicker,blacker.
That's my experiences.
I remember the mechanic.dunno where he went.jimmy Hendrix looking with red hair!
