Oil Deep Dive at GPI 

awesome info, wish i could watch the whole thing lol. thanks for sharing

I watched the first 24 minutes, but you lost me once I checked your website. Why do you use a WIX XP oil filters in your Gen IV LS oil change kit? XP filters are advertised as "extended performance" but the they just use a larger micron rating to achieve this...meaning the holes in the filter material are bigger so they let more contaminants through. WIX XP is garbage, I learned this the hard way using a wix xp air filter on a duramax 10 years ago.
