Hey everyone
,my letter to FRAM is first, followed by their response.Here goes.
I used to use FRAM oil filters but have stopped because of build quality.While I prefer metal endcaps for the filters,if a good quality cardboard is used,a cardboard endcap filter may,may just be adequate(?).Also,sealing problems inside of the filter are an issue.The plastic parts that are used along with the metal springs and the cardboard ends just don't make sense,great glue or not.Another problem that I have with FRAM oil filters is the small inlet holes in the filter base.Are the holes small so that they restrict oil enough to keep the pressure low so that the filter internals will stay together? The inlet holes are just to small,larger holes would benefit the oil filters greatly.The holes cant flow as much oil as filters that have larger holes,which is all filters that I know of.Also,if cardboard end caps are of a great quality,why is the X-2 made using metal endcaps.The metal endcaps are the norm when it comes to the everyday plain off the shelf Champion Labs,Purolator and AC Delco filters.Champion and Purolator are usually cheaper than FRAM and of a better build.I just do not understand FRAM's reasoning behind the cheap internals of their filters.As large as FRAM is,your company could compete very well in price and quality as the other main filter companies(Purolator,AC Delco,Champion Labs).I would really like to use FRAM once again but the quality keeps scaring me away.I have read comments to others from FRAM regarding the build quality being great because of the glue and cardboard making a superior(?)seal etc.What I want is for you to tell me why I should by a $3.00 FRAM with its current quality over a $2.88 Purolator that is built better and stronger(metal endcaps in the base filter) .Even if things in both filters were the same(which they are not),why should I buy the more costly FRAM? I want this in plain simple language,no mumbo jumbo,just plain language as to why the FRAM is the better choice.
Thank you for the e-mail regarding of Fram oil filters. We welcome the opportunity to be of service.
Fram indeed uses a cardboard material in the construction of its oil filters. Fram filters meet the requirements of the original equipment filter designed for a specific engine. Our filter applications follow the recommendations of the vehicle manufacturer for form, fit, and function. Fram filters follow internally targeted design guidelines to meet the functional requirements of a given filter. Fram filters are tested against SAE standards to ensure uniform product quality and performance. Material construction will vary between filter manufacturers. We welcome the opportunity to enlighten you on the subject of cardboard used in Fram end disk construction.
A common misunderstanding among our customers concerns the end disks in the oil filter. These disks hold the glue which keeps the pleated media formed into a rigid circular tube. The glue-to-media interface is also one of the sealing surfaces keeping dirty and filtered oil from mixing. One common myth is that only metal end disks can adequately seal and have enough strength in the hot oil environment. For this reason, Fram filters are criticized for having cardboard end disks. The issue is, the material doing the sealing is the adhesive, regardless of the material of the end disk. What matters is the strength of the adhesive, its proper curing, the thoroughness with which it can be applied to the disk, and its adhesion to the disk. By using cardboard end disks, Fram filter engineers are able to specify adhesives with excellent strength and sealing properties, and strong adhesion to the disk (intuitively, it is easy to make a strong glue bond with cardboard). Moreover, just as paper media itself is able to withstand the hot oil environment, so too is the end disk designed of fibers engineered to be strong and inert in hot oil. The thickness and strength of the adhesive also stiffens the end disk considerably.
How do Fram engineers test these end disks to know that they hold up on the job? Not only do they perform hot oil circulation tests on the filter element, but they also regularly cut open used filters to examine how well they have withstood the rigors of actual use on a vehicle. For over 38 years, Fram end disks have stood up to hot oil and their adhesives have sealed off the dirty oil.
Regarding the metal end caps used in the X2 series, the Fram X2 Extended Guard filter uses a filter media that includes a reinforced mesh screen for maximum pleat integrity, durability, and oil flow. The inclusion of the metal screen increased the glue tolerances or thickness required for proper adhesion to the end disk. The original X2 prototype development specified the cardboard end disk technology. However, the increased amount of adhesive required to join the cardboard end disk to the screened media resulted in prototypes that did not conform to design standards. We had no choice but to use a steel end disk with the X2 filter media to provide uniform Extended Guard oil filter construction.
We are unable to comment of the pricing of Fram filter versus competitor filters. Retails outlet pricing will vary from company to company as it is their channels that determine what final price they will offer the consumer.
We believe that FRAM filters are clearly the best filters available. Fram is committed to standing behind and endorsing it's products and filter recommendations listed in the current Fram application catalogs. As part of this commitment, if you should ever have reason to suspect or question the quality of a Fram filter, we encourage you to contact the Fram Product Evaluation Team toll free at 1-877-250-8361 for further assistance.
Thank you for choosing Fram filters.
Cordially,

I stiil did not get all of my questions answered,hole size was not even discussed.The reason for metal ends in the X-2 still doesnt make sense,a thin metal screen does not add that much to the thickness of the filtering material.Is it just me or is this just more of FRAM's garbage?
