ARP says to use the proper lube for a reason..

For no reason; I don't have 50w. I do have moly-lube.

I'd go with what ARP says.

You can buy a stretch indicator and use nothing but light oil if you want to be real accurate

ARP moly

I would say you can use either one. Just adjust the torque specs to what you are using.

For pro mod stuff; when at the shop we use moly, when checking bearings at the track we use oil.

If you read their instructions they supply, they indicate you can use either one.

The amount of torque needed to get the fasteners to stretch correctly is the trick.

The torque specs listed by them are meant to be used with their lube.

If you use motor oil it is 2 to 3 TIMES as much torque according to them.

I found this out when reading the specs for a set of head studs we pu in a motor.

If you got to ARP's website click on the link for the 2009 catalog. Go to page 24 and they have a torque chart that shows you torque with oil and moly.

This is a good chart to have when putting any engine together.

The "new" ARP product ad states that you may "see" torque "scatter" with products such as oil. The new lube, [ULTRA-TORQUE], is supposed to reduce the scatter from getting 60 to 70 % of what is required, to a 5% scatter.
The part number of the new lube is: 100-9910
Summit will have it this month... About $20/bottle.
