So I’m real confused as to why ever since I’ve added the Metco crankcase breather my oil consumption has stop ! I would use about a quart every 5,000 miles and was at the point of acceptance of this amount of usage at 21,000 miles on my 2015 Dodge Challenger Hellcat M6 . I suspect I was getting a lot of crankcase pressure and it was causing blow by somewhere ! My HC has a catch can on the passenger side which I added way before the crankcase breather and did nothing to help oil consumption and would catch a couple of ounces between oil changes . These are the only mods it’s stock besides these two items ! what’s everybody’s thoughts on this !
