Is it Castrol Ligui Moly additive? Synthetic? Can't seem to find the Guard Dog gear additive?
Pulled the head and cleaned the piston faces. This thing only has 32k miles on the clock; I can't believe how dirty the pistons were. And the exhaust ports?!? Filthy!Still need to clean the head gasket face on the block, pull the pistons and clean any residual crud from the rings and ring wells.Please to see the cylinder walls look like they were honed yesterday; simply perfect!
