Ron did some extended Timken testing last night utilising his new heat gun. BP Visco 5000 5W40 in the blue corner, just arrived Redline 5W40 obviously in the red corner and new Castrol R 0W40 in the silver corner. Castrol R cold lockup at 30lb, 100lbs capability at 210c and 120lbs at 500c. RL cold lockup 30lbs, 60lbs at 210c and 110 at 500c. BP Visco 5000 no cold lockup and just powers to 120lbs at 500c. Interestingly adding Auto-Rx to the V 5000 took it to 150lbs. Ron will do RL and Castrol R again tonight with Arx added. By far the cheapest and least known oil is killing everything. Some even believe it's a Group III and not a PAO which if correct makes it even more amazing. Pennzoil 15W40 Longlife, BP 15W40 Visco Autogas, Delo 400 and Mobil Power Guard Delvac 1300 Super next we hope.
