The X2 is a good filter and one of the few on the market that claims to be intended for extended drains. I personally don't care much for their bypass valve (where applicable), and their silicone ADBV is probably the weakest among the "premium" filters. The filter element itself appears to be of excellent construction. When I compare it to other filters on the market, it strikes me as $6 filter.
if i'm not mistaking, i beleive most if not all the filters you see on the shelfs will go 7,500 mi. they have to be able to function properly and do a satisfactory job during what i still beleive a "normal driving" drain interval for a lot of cars and we all know the europeans go much longer between drains.
Yes, it is way better than a ST filter .The media is very advanced I use one on the v6 toy p/u and a Fleetguard stratopore on the wife's Powerstroke .That is my preferance but in reality any high quality filter would be fine "very little if any difference"
I've only had two oil reports on my 2003 toyota corolla with the fram X2 so far. Another should be coming in a few more months(I only have a little over 8K miles on the oil today). So far it seems the X2 is doing a decent job. My engine hasn't blown up or anything. the third report will be a 15K mile report with no filter or oil change. report 1 report 2
kwikrnu I agree your insolubles are in check, in fact they seem to be average. However, the question was if the X2 was worth $8 more than a ST filter. Judging solely by the UOA, It appears that it is not. But perhaps a UOA isn't the best way to determine a filters effectiveness.
