I stepped away from the forums for a few years and upon my return the once "amazing" puralator and motorcraft filters are now trash and Fram seems to be often recommended. I've been using the larger than spec FL400s on the 2.0 Mazda, but now our local Walmart doesn't carry this filter. I need to change brands and buy Instore (fram) or look online for Motorcraft or any other brand. What's your recommendation as we typically run a very extended OCI (10k plus)? I prefer to stick with the larger filter which isn't the spec for the car. Bosch 3422?
