I actually used Arco graphite in my Fury , Phoenix Police Interceptor , Blues-Mobile -huge V8 with Thermo-Quad Carb , equipped naturally w/ 140mph speedo !!
Cop motor ,cop tires ,cop suspension , cop shocks ...........The Blues-Mobile
Took off like a Jet Aero-plane . My oil useage got to be 1 1/2 qts a month. Started having to use Anti-fouler (plug extensions) ........ ended up with 4 extensions , and actually one virtually dead cylinder.
That Graphite SURE was goofy , went back to reg. Dino oil .
Now I'm not sayin the Arco G did ALL that , that Interceptor had well over 200kmi, as deduced from second odometer turnaround !!
My opinion is brake pads & oil kinda like a 'mystery' if you will , a crapshoot , but I developed "Fuzzy-logic" with those subjects , and so - what do I , or most civilians REALLY KNOW ????
