XP- They wont release efficiency at 20 microns because it's dismal. They cost more. WIX makes no claims as to how many miles it will go to full capacity. They are in fact redesigning it now because well, nobody is buying them. Honestly do not care what you use just curious as to why?
I like the Fram Ultra, and it is an awesome filter, and probably does filter better than the XP/Platinum, and I like the Suregrip, but Wix does have more XP applications than Fram has for the Ultra.
However, I do prefer the Ultra in applications that Fram actually makes it for. I use these synthetic filters for extended OCI's 10k or longer on cars that don't use an OLM. On cars that do, I use (regular) Wix or Fram TG, except on MM-equipped Hondas, which get a PH7317 since that is the A02 OEM filter.
The Subaru high-psi bypass 57055XP. Fram does not even make a Subaru-spec filter.
Ford's Zetec filter, Wix 51315XP. There is no Ultra XG8316.
Since the Focus doesn't get driven more than 10k a year, I will use the new silicone PH8316 on it. Right now, it has a non-XP Wix 51315.
Also, in regards to the Pentastar Ultra, XG11665, This particular Ultra is Korean and uses a plastic mesh like the Purolator Boss and some German OEM Manns. Is the XG1165 outsourced to Mann Korea? Anyway, someone else on here used the plastic mesh XG1165 and it still buckled! The recently-released Wix counterpart, WL10010XP (Napa Platinum 4100010) uses a metal wire backing like any other XP. See
this thread.
The Volvo Ultra cartridge XG8712 is $27 at Walmart! The Wix counterpart 57021XP can be had at least $10 less.
The famous VW 2.0T can with the hex key thing is over $30! Wix doesn't make an XP for it, so my choice for this application would be the M1-404A, which is good for 20k and the parts stores charge a fair price for it. In fact, the 404 is even included in the oil change bundles. This is one of the few cases where I'd use a filter for more than one OCI, simply because they are so expensive.
Other than the above scenarios, I still love the Fram Ultra, and I know it is a great filter at a great price. But there are a scant few instances where it cannot be used.
