Just wandering is anybody using the 10-30 z-rod oil in the gt500 I looked at the UOA thread but it didn't specify what 10-30 was analyzed any info appreciated
Thanks
Thanks
I forgot to add I am currently running the RD-30 but Amsoil tech told me that it is only to be used a couple of races
So if I am running the stock thermostat I shouldn't run 10-30?
