I hadn't seen this posted previously. I got to thinking about Champ's big switch to Ecore as much as possible in 2003 for their own brand, and lack of competition from Champ with the many 10K miles oil filters on the current market, many from outside the USA.
Well it turns out Champ now offers Champ XL oil filters. Named synthetic, further detail shows these are a synthetic blend media. No mileage rating, efficiency, or dirt holding capacity is shown in the literature I've been able to locate thus far, so I plan to call Champ with these questions. I know there's selective value or lack of it placed here by answers obtained from company tech lines, especially if it's not their pet brand, but it's the best avenue I see here to get that data.
What really interests me on the marketing cutaway document, the example filter shows the typical pre-Ecore Champ base end bypass design as well as a silicone ADBV and as mentioned earlier synthetic blend media. I always liked the base end bypass feature of the pre-Ecore STP oil filters made by Champ, still employed on a few examples today like FoMoCo factory filters, the Mobil 1 M1-209 & M1-301 models, etc.

Has anyone here seen one in the wild yet? Especially board members who work as mechanics or installers, as these seem like the regular Champ brand to be targeted at the Do It For Me market.
