Royal purple 0-8w.

They say this oil is a little faster than reg oil. When I put it in can I run it all the time or does it hurt the motor to run this oil all the time? Thanks

You can do what makes you comfortable, but that is a very thin oil.
Will it make a little more power? For sure. I would save it for heads
up runs when you need a little help, and run something a little
safer for everyday racing. i.e. hot weather, hot lapping, late night
moisture, etc. Just my thoughts. J.R.

X3! I know some Pro Stock cars run it all the time. Different deal there.

X4. For me, just not worth the risk and expense.

There's a balance between those thin oils and the rod/main clearances. Clearances that work fine for 'normal' oil viscosity (5w20, 10w30, etc.) can get you into trouble with the lighter viscosity oils. And the clearances needed to run the lighter oils...all the time... can paint you into a corner if you want to use the heavier stuff.

Do your homework and make sure to involve your engine builder. -Al
