i like vapor use mobile1 15w-50, simply cause it works so much better in my car. some people say 50w, wont go thru honda bearings......bullshit, they only recommend whats typed on the oil cap for regular daily driving and durability. but we drive our hondas different than most regular people. so for the extra few dollars, i want the assurance that if most of my oil fell out, i would still okay for a tiny bit longer......................my .02 cent
