Yes , it’s shaping up to be unfortunate when you cheapen the Ultra oil filter then develop the Endurance oil filter with better flow chatecteristucs while keeping the same high filtration as the Ultra but now the Endurance has what appears to be a design flaw . Done properly , Fram could have marketed the original Ultra as being superior to bring top dollar while still being profitable . What appears to have happened is Fram owners went with a philosophy to drive out costs - along with the quality that made your oil filters stand out from the crowd .It's a darn shame when something is good the company making it doesn't leave well enough alone! It all comes down to profits, 99.9% of the time no matter who, no matter what! I gave up on Purolator years ago for that reason, looks like Fram might be next!
