Good Afternoon Oilgeek,
I look at 3 performance criteria in an oil filter; the efficiency @ micron level and life rating and then look to pricing for value.
1. CarQuest 84806 claims 99.5% @ 20 microns @ 10K mile life for $14.79.
2. Fram Ultra Synthetic XG10415 is >99% @ 20 microns @ 20k mile...
Here are the results from the Fram look up that I trust:
WRX- XG9688 Ultra Synthetic
Crosstrek- XG7317
Forester- XG9688 for both engines.
If your OCI is 6k or less the Tough Guard line will be excellent too. Use all with confidence.
By the way, you have excellent taste in cars! :)(y)
Good Morning SubieRubyRoo,
Another well written comment by you on the history of this topic on Bitog, the reality of the volume of non oem filters used on Subarus and how good driving habits win the day for filtration. Most appreciated, thank you.
Hi Everyone,
Back in February in post #41 of this thread I reported changes to the Fram Extra Guard. Recently while in my local WalMart I checked out the Extra Guards and they are back with their original silicone antidrainback valve and louvered metal core!
Good Morning Hrv,
Thank you for sharing the video.
I found it interesting that the guy spends 8 minutes 11 seconds trying to site differences and does not know the most important and only criteria to compare; filtering efficiency based on ISO 4548-12 and rated mileage life.
But citing data...
Good Morning GMBoy,
I really appreciated your feedback, thank you.
End caps are an interesting feature of the filter. I recently watched the 2011 Fram video on the engineering and testing of oil filters and I learned the end caps provide no structural integrity; that they only exist to seal off...
Good Morning GMBoy,
I'm curious about your preference of the MicroGard over the Fram Extra Guard. The Fram has better performance specs (95% @20 w/10K life) with a lower price. Not challenging you, just curious about your experience/perception of the product. Thank you!
Good Morning ARCOGraphite,
This UOA from 2019 has to be one of the best I've ever seen. I look at three items; Iron, Silicon and did the oil stay at its viscosity rating. You hit the trifecta, great numbers on all three. A sign of both excellent maintenance and driving habits by you.
