That helps the filter maintain its seal so oil flows through the media, not around it. A collapsed center tube allows virtually all the oil to by-pass the filter media and circulate unfiltered. Oil filters need good efficiency and good capacity to protect engines. Those with poor efficiency fail to trap a significant portion of particles large enough to damage the engine. Those with poor capacity fill quickly, and once filled, allow dirty oil to bypass the filtration media, circulate unfiltered and damage the engine.
Capacity becomes an especially critical issue with extended oil drain intervals.
The Super Duty's advanced media blend, particularly the cellulose and synthetic media, provides this outstanding capacity. The fineness and uniform strand shape of the Super Duty's glass and synthetic media give the filter its tremendous efficiency. You've got nothing to loose. We're taking all of the risk.
