Who has used ARP's ultra torque lube and did it work as advertised?

 

I've used a lot of it. It doesn't tend to overstretch bolts after multiple torque cycles like their original formula did.

 

I used it today and it works as they say it does

 

You need to measure stretch with rod bolts when using the new ultra torque lube, the specs supplied so far are generally about 10-15 lbs too low in order to reach the proper stretch.

Consistency with the new lube is great, but ARP and the rod manufacturers torque data is severely lacking.
