Hello Folks! Here is Fram Ultra Synthetic XG6607 cut open after a 2,334 mile OCI with M1 0w-40 oil on Nissan's VQ37VHR engine.
I was surprised to see such a short filtering media. It almost reminded me of a hockey puck. Nevertheless, the filtering medial is fairly long when expanded and quite thick. I have no doubt it filters oil very well.
That said, I have a concern about flow rate of this filter. Some of you will flame me for this, and I did see a chart that shows Fram's Ultra having highest flow rate, but that test was not on XG6607 filter.
Moreover, when I just installed the filter with fresh oil and took car for a test spin if felt as if the vehicle is struggling to accelerate. Next day, my wife who is a primary driver texted me saying, - "What did you do to the car? It feels like it doesn't want to go".
I've just changed the oil this weekend and installed Purolator PureOne PL14612, with the same weight oil, only it is Castrol Edge 0w-40 (German Castrol made for NA market). The car wants to fly again! What gives? This was my only experience using Fram Ultar. It had been PL14612 all prior OCIs.
Just sharing info and driving impressions.
