If the pressure in a filter was going to deform the fram endcaps wouldn't it also do the same to the filter media anyway?
This post sure makes sense to me. Would anyone else care to explain why the endcaps need to be stronger than the filtering media itself?
I've recently learned that Nissan OEM oil filters are now made in China and they have cardboard end caps like a FRAM. Scary ... especially at about $10~$11 a pop. Of course they must perform well if Nissan is going to warranty their cars using them.
I think that you will see more companies use the fiber(cardboard)end caps. I have seen a Mann filter with fiber endcaps. You have to understand that the end caps are not everyday cardboard. Alot of the OEM filters in Canada are indeed made by Fram. Do you think Mazda, Honda, Toyota etc would allow Fram to make OEM filters for them if Frams failed all the time and were junk?
In Canada we do not have the luxury of the number of cheaper filters that our American friends have. Fram is the cheapest filter here.
According to the parts counter guy at my honda dealer, FRAM was an oem filter mfr for honda oil filters (well, parent company allied telesyn). 3 years back they changed to different manufacturer. Said they were seeing TOO MANY FILTERS DISINTEGRATE CAUSING ENGINE DAMAGE.
When I bought the car a cpl yrs prior the sales guy even told me that diy service is fine, keep receipts, but... said he didn't know specifics but knew Honda was dealing with a bunch of oil filter -engine damage claims-- so he wasn't sure why but for liability purposes suggested buying the honda filters... so even then, before they switched, while he didn't understand the whole shebang he'd even heard of filter failures.
