My vehicles for many yrs have gotten nothing but Fram Ultra and/or Titanium filters. Both are arguably the best filters made. I do used oil analysis. I post the results here. I cut open the filters and post here. Never an issue.

For several years, independent lab analysis showed Fram filters to be subpar in both filtration and quality, but in the last several years that has changed and now they're back to the top. Seems they're still suffering the effects of the public perception problem they had during that time. Lots of manufacturers went through a period of cost-cutting followed by damage to their brand in the 90s.
