Really, what Oil Filter are you looking at for your car? I think that all of Champs Oil Filters will have the same Efficiency Rating, meaning Micron Rating. Is this a Cartridge or a Canister Type Oil Filter? How long is your OCI and what oil are you using now?
I highly doubt Purolator/M+H has actually ran an ISO 4548-12 test on every oil filter model they make. The man-hours and cost would be crazy high. They most likely have a computer performance model based on some actual ISO testing of a few models that they did, then apply the computer model to each filter knowing it's physical design, and come up with an efficiency number that's dependent on the physical attributes that can impact the efficiency, like the type of media used and the total media area.
Zee0Six, what you said is what I wanted to say, you said it better, because what I would have said would have not sounded as good as what you posted.
I’ll say this. The Pure One and new version of the FRAM Ultra have been showing poor construction in the dissections here. The Champ XL filters have shown much better construction and quality control.You would think you would hear a lot more members on here recommending them since they are the same micron rating as Pure One and Fram ultra.
I have cut open a couple Champ XL filters, from my neighbors car and it has been consistent.. I also bought a PH 500XL a while ago I put pictures up here, and that was consistent as well with the Nissan Rogue filter of my neighbors, that I cut open.. I bought several tonight. $5.50 a piece including shipping..
You can say the same thing about Fram too then w/the whole "Equivalent" wording right?
I was at orielys today this morning and checking the filters out while getting some windshield fluid. I opened an Wix 51516XP and to my surprise inside the louvers i saw brown cellouse media and no wire backing. Made in USA with a Mann Hummel label on the back. If ya thought Fram is cheapening pretty bad. Its far worse on the Wix XP i saw today a 15.99 filter.
I wouldn't doubt they try to pull a fast one, how many people, out there actually cut open oil filters.. They will save quite a bit of money on the manufacturing cost.. poor ethics though..
Some members do bring them up, but they are much harder to find to buy. If Walmart for instance carried them, more people would be buying them IMO.You would think you would hear a lot more members on here recommending them since they are the same micron rating as Pure One and Fram ultra.
They at least reference 3 different sized filters in their efficiency statement that have had an actual ISO 4548-12 test done on them - and it's the size (ie, the media area) that would impact efficiency the most with other factors being constant. We've been over that many times already, but doesn't seem to register.
I was a loyal wix user for years, until I got a air filter like 2 years ago - made in Spain, not USA. No metal screen. Cost much more than before. Last M&H product purchased, or I will ever purchase. I would roll my own before I buy anything from them again.
I ended up grabbing a Microgard Select MSL51516 there instead for cut and post thread. The difference in quality was a night and day difference and decided against cutting it open haha.
That sounds like Fram doesn't ISO test all of their filters either.. That's my point.They at least reference 3 different sized filters in their efficiency statement that have had an actual ISO 4548-12 test done on them - and it's the size (ie, the media area) that would impact efficiency the most with other factors being constant.
