Sorry if this is re hashing an old subject. Quality of filter an capturing contaminates without sacrificing flow rates I’m kinda torn between these filters..it seems quality products is such a hit or miss these day’s or maybe I’ve been researching this topic way to long..both filters seem to have good build quality but is flow rate and the ability to capture an contain contamination better in one of the two filters?
Royal Purple or Mobil1 Ep oil filter
- Thread starter oilwise
- Start date
Mobil 1 has changed manufacturer recently.
Out of those two I would go RP (if it hasn't changed as well)

RoyalPurple is full synthetic media.
Mobil1 is NOT a full synthetic media. Why pay extra for cellulose blend filtration???
Use the RoyalPurple, Amsoil, Napa Platinum, WixXP, Fram Ultra, or Purolator Boss filter.
When M1 comes out with a filter with full synth media, I will recommend them. Until then, they are the marketing master selling a filter at high profit margins.

Ability to “capture and contain contamination” is related to the filtering efficiency of the filter. What is that for the two you’re considering?
I read somewhere that there is actually some benefit to a blend as the non synthetic media can absorb at the same time that the synthetic media traps. Theory? Marketing hype?

Absorb is not a good filter property in full flow filters. It essential expands the cellulose and restricts flow. Cellulose is treated with resins to avoid absorbing. The only benefit to cellulose is that it is a cheap fiber.
Cellulose is obsolete. Just use a full synthetic oil filter if you are paying for a premium filter.
Supertech or Fram ExtraGuard.... vs Mobil1... I wouldn't bother with Mobil1.

Has nothing to do with being a race car
Why not just get the Fram Ultra from Wal-Mart? its readily available well built great filtration syn media and you don't have to worry about ordering on line
Royale Purple all the way! 
Royale Purple and Mobile 1?Royale Purple all the way!
Purolator Boss has one of the lowest efficiency ratings on the market at 20 microns.

And still better than the OE filters I've used in my Toyotas, Lexi, Kias, Hyundais,.... and anyone want to wager the Mahle/Mannhumel filters in my VAG products. Give you a little hint, many filters, especially from Europe, have even worse efficiency. But, the fanboys use them because they look the best.
I'll take that Boss over any OE spec'd Mahle, Hengst, or MH.
Speaking of MH, they recently release full synthetic media filters for some VAG products. They must've learned something from their Wix/Purolator acquisitions.
The Purolator BOSS is shown as 99% @ 25u on their website ... so not as bad as you make it sound. It's hard to find, but it's at the (*) at bottom of the page.

The Mobil 1, Napa Platinum and Wix XP have worse efficiency ratings than the Purolator boss. Purolator boss is middle of the pack at 25 microns.
