We have ran it for a long time. Actually had the oil pump pick up break off and made entire 7800 rpm dyno pull with 10 psi pressure and the bearings looked new. Yes, the dyno operator was a bit red faced, but it turned out alright. That's what really sold us on it. We use the 10-30 Dominator, but I know some people with tighter bearing clearances than us run the Dominator 20w all the time. I've been told its slower than most oils on the dyno, but if your looking for protection, its a great choice.
