In my other cars I use the Mobil One oil filter. Which is the best filter for our Ascents? Subaru’s or someone else’s? And why?
Over the years, a number of people have taken it upon themselves to attempt to test and qualify oil filters, primarily by disassembling them and evaluating the overall construction and materials used, especially the filter media and the quality/quantity of it. These tests have merit but are not definitive. Unless someone such as Consumer Reports decides to perform unbiased scientific methodologies to testing oil filters, the best we can do is to try to make educated guesses based upon what little comparison information is available.I choose Fram because it's a good filter. I know this because I used it on my 2000 4runner, ran it 200K+ miles before I sold it. 9/10 times, we don't often articulate why we choose one brand over another, other than the cost. The cheapest Fram (orange color) is actually few cents more than Subaru brand, which is surprising to me. When we look at filter comparison, we should aim to evaluate based on the following criteria:
1. contaminant removal efficiency (in %)
2. contaminant removal capacity (in mileage)
3. Hydraulic flow rate capacity (i.e. oil flow rate thru its life) (in volume/time)
If we can articulate with some sort of metric, as suggested above, then we can qualified them as the "best". otherwise, it's just utterances.
There are a lot of YT videos of comparing the material use but not the actual performance. There's a lot of merit to compare oil filter by the construction method and material. if that's all we're evaluating, then we haven't done our best to figure out which is the best. All it is saying is that we've chosen one over another because of the dollar cost to construct them.
I would think there are better ways to save money than second guessing your oil filter.I got an STI filter to put in my wife's forester but traded it for an ascent last month.
Anyone see any reason this will not work fine in an Ascent?
I understand that the blue Subaru filters have cheap cardboard filter caps inside that fall apart, but the black ones are still made in Japan and are higher quality.
It has the 23psi bypass meant for the WRX turbo so I am sure it can handle the ascent's turbo oil pressure without constant filter bypass (unlike a lot of aftermarket filters running at ~10psi)
