Sounds too good to be true. They also add some snake oil into the "proprietary blend" for an extra 50 HP!!!

I use Mobile 1 Syn Extended Miles 5W-30 thinking the extra cleaning additives would help. My engine has only increased oil consumption in the last year --- since the switch from regular Mobile 1 syn 5W-30.

I've heard mixed reviews on the planet and I believe that's why Jerry made the post about it taking a while. Worth a shot... maybe a combo PCV fix + engine cleaning=
