hm... that reminds me, i haven't seen a fresh oil thread in a while...

There's been an opinion expressed, on more than one occasion, that certain motor oils may be of help with blowby. Searching will turn up more discussion on the subject than you'd ever want to see. Myself, having been awed at the amount of blowby my car has, I opted for 15W40 oil (dino), and it did help some.
