From their website:
Fram Tough Guard Uses a higher level of synthetic media to give 6X MORE engine protection than the average of leading economy oil filters -- VS. AVERAGE OF LEADING ECONOMY FILTERS. Honeywell testing of filter efficiency and capactiy of models equivalent to TG8A, 3387A and 6607 under ISO 4548-12 for particles > 20 microns.
Unsurpassed 99% Dirt Trapping Efficiency -- Honeywell testing of filter efficiency (using FRAM XG3387A and XG8A average) and dirt holding capacity (using XG8A average only) and their leading economy filter equivalents under ISO 4548-12 for particles > 20 microns.
I like how they misspelled capacity.
