Has anyone tried CM Filter housings & elements?

New to the forum......

I have a 2005 SAAB 9-5 Aero (4cyl Turbo). Per the manual, I should be running 0W-40 full synthetic and changing every 15k miles, but the dealer is advising changes at 7.5k - both seem long to me.

However, I'm putting on 800 miles a week commuting (mountain road & freeway) and want to be able to at least push the changes to 7.5k without worry. So I'm looking for a better oil filter to help do that. (I want to get at least 150k miles out of this car!)

I am looking at: http://www.cmfilters.com/spin-on.cfm

The CM has changeable media that is rated at 8 microns, flows 20gpm, and has no by-pass valve (is benefit that it filters all the time?). At $14.50, the replacement media alone costs a bit more than a mobil 1 or Amsoil filter, but it would be worth it to me if the CM would do a significantly better job keeping the oil clean. I can also get the CM in a 4-5/8" size, which is larger than the standard puny SAAB that is less than 3" tall.

Do you think the CM would be better at keeping the oil clean than an Amsoil or Mobil 1 spin on filter? Also, any problem with not having a by-pass valve?


Thanks for any comments you might have.....

I've also got some questions on types of synthetics to use, but I'll post in another topic.

Thanks,

I don't know about the CM filters ...but the initial and recurring costs are too much for me. I'd go with Amsoil or M1 for your needs.

You can also get bigger spin on filters for your Saab. It's the most popular thread/gasket size in the world with many variations being available.

I am considering a CM filter for my Accord with the thought that if it really does what they claim, the intial cost and filtering performance is pretty comparable to adding a low cost bypass filter, and then with the CM you don't have the bother of dealing with both the bypass and FF systems. The big issue holding me back from doing this on the Accord is that the filter location is such that I think changing the CM element would create a huge mess of spilled oil. If I figure out how to overcome that issue, I will probably get the CM. If I can't, I will add a bypass unit. I called CM a while ago and they claim these filters are used on racing engines, so they apparently have enough flow capacity even without the bypass valve.
