It takes about 10 seconds it takes to pour it in the oil, or about 10 seconds to pour it in the valve cover. Only 10 seconds it takes to shake it up, I think I'll go ahead and pour it in the oil, ya know, pre-mix? 10 extra seconds... C'mon, man!
I do the same thing...been doing it for years and years....You will not convince anyone to change their ways...Just like they will not convince me to buy expensive special purpose oil....
They should make this topic a sticky...cause it will come up in another week...and everyone will post the same stuff.....Do whatever works for you....my 360s get down the track pretty good with no valve train problems...
