Cheap filters flow well, which some of us want - without higher filter costs.
My Premium Guards from Rock Auto are $1.41 with 96% efficiency. A well known filter cutter here is very familiar with the filter maker and says I should be fine for my 5-6K OCIs.
I want quiet startups, and high standing idle pressure rates on my oil gauge, which I didn't get with my last purchase of Fram Ultra
I'm not debating this, for you cannot see and hear my Chevrolet 3.5 engine, vehicle and gauges. So replies to me will not be challenged. These Premium Guards get engines to 300K also. Oil filters on today's high tech, highly evolved engines are overrated and not needed anymore. Engines are not designed to house sludge anymore. Gaskets to seal from oil contaminants are better than ever.
I am 1st and last owner of my vehicles. If I thought the properly chosen cheap filters today wouldn't get me 16-18 years of service on the same vehicle, I would not run them. Some cheap filters are lousy..... some aren't, when used correctly.
