The 90915-20004 is a nice filter. I've had oil analysis done at 6, 8, 10 and 12K miles. For ours, it has good filtering properties that I don't think of another. YMMV.

Wow, are you saying you have gone 12k miles between changes RA40?

I should be doing my oil change pretty soon, has anyone use the fram high milage oil filter and use eneos oil? I use to run eneos in my subie and it did the job, just wanted to see if anyone else ran it in there ucf.

Yup. The additive package is dropping in the Mobil 1 by then though it still is sufficient to do as necessary if one stretches it. 8-10K is nominal in ours and the filter is still keeping up. I don't cut the filters open. The analysis is sufficient to determine that excessive wear particles in the oil that are not getting caught/filtered. Within normal spec, which is the goal.

Sorry, no analysis data to post, long deleted and the one hard copy, I'm not about to type up and that was wayyy back in '02 or so when I did the baseline at 60K. I wanted to determine what is a good drain-filter replacement schedule in ours.

The JDM 90915-20004 is quite capable. I recall seeing data from the Supra forum that expressed similar and there may be past discussion in the GS section as well. Suffice, this is a well liked filter but a bit $ now.

it won't matter - just use the STP filter. the car won't know the difference.

Yeah, I like these filters a lot. I have been using them since early 09. I got a great deal from another member two months ago, $60 shipped for 6 filters.

I use Fram in all my cars including the antiques. Also in the boat and never had a problem.

Folks, are these two filters the exact same filter? They look IDENTICAL. In other words, does WIX make this filter for NAPA? If so, if I can get the WIX filter for $2 cheaper than the NAPA filter, wouldn't it make sense to buy the WIX filter? Especially if it is literally the same filter?

you can call wix, they tend to reuse external casings so unless you cut two of them open you wouldnt be able to tell if the bypass and filter material is the same.

I read something recently, within a week, that Wix and Napa oil filters are made by the same company. I can't remember what the company is though. I was searching for something else and that came up.

somnoboy

Ok, thanks guys.

Wix is the company that makes napa gold filters. wix also does a lot of OEM filters.

but you can't compare casings to casings, you either need to call wix to compare 2 model numbers or cut them open.

Well said!!
