Different requirements of oil between engine builder, turbo, or camshaft? Who should I listen to?
My engine builder told me to use Valvoline conventional 20w-50
Isky cams says: low viscosity Brad penn grade 1, pennzoil GTP, and valvoline racing oil (especifies, do not confuse with conventional valvoline)
And turbo builder says, rotella 10w-40
Which oil should I go with??
Thanks guys!

Your not breaking in an engine with the power adder on it are you? You must be very sure you run the correct additive package for the camshaft and rings to assist in the break in process.

The roller camshafts don't need the additive package as there is no break in in most cases. It will assist in the ring break in process. Use what the vendor/builder recommended. We use the Brad Penn break in oils and go over to Royal purple once we are satisfied break in is all set.

@ expensive break in oil.. It's a hydraulic roller.. Properly grease your pushrods and you'll be fine. Go find yourself the cheapest Walmart 15W40 you can find and drive it like you stole it. Change your oil after 500 miles and go with a decent 20w50. My .02 
My engine was built with looser clearances, so 20W50 is what was recommended by my builder, and that's what I have ran. If your builder is recommending the same, I would go with what he says.
FWIW, FI cars do better with a higher zinc concentration in the oil. The least expensive high zinc concentration oil happens to be Valvoline VR1 racing 20W50 (which is what I run).

I don't know the answer to your question, but I wouldn't think it would play as big a role as the clearances in the motor would. It's not like running a thicker oil will lead you to over temping the motor even if a lighter weight oil is better for hotter temps.
Well, I was thinking that switching to VR1 20w50 would help oil survive living in a turbo setup better compared to say 5w30 of the same VR1 brand. But I guessing! LoL
What is really better suited for turbo use ? Or does that really matter, maybe I'm over thinking it. Maybe I'd feel better about it with a oil cooler!
