R u guys having good results from ???

 

I run Lucas. I can tell it help the oil from getting as hot, when I pull the dip stick from a few hard runs. It doesn't lose its viscosity as much.

 

I just changed the oil for the first time since rebuild on dad's LS Nova after 40 passes on Valvoline VR1 20/50 and it was still clean a lil black but not a single trace of any kind of bearing wear not even on the oil pan plug which is magnitized. This car is track only so it only sees full throttle so i would have to recommend that. And i know its not an additive but man its gotta be some good oil IMO.
