This filter thing seems like an unneeded expense to me.

Hope your engine doesn't end up baked, but to each their own. Every added measure of protection in my engine is worth the dime spent. Charles/LN Eng and Jake Raby didn't design and test these items because they thought they were trick or cool. The Porsche engineers were overruled by the accountants...that's why we have well thought out aftermarket components.

I change my oil once a year, which typically does not exceed 2500-3000 miles...and I don't use M1 0W40.
