It's specifically for lighter weight oils. Actually says right on the label it won't void warranties...???? Anywho, the stuff isn't like 50weight oil like the regular stuff. This actually poured out pretty fast and was much thinner than the normal stabilizer crap that i would never have used.
It's not even a 30weight consistency. It poured as fast as the 5w-30 did. It just has that really stringy nature so it sticks to walls and moving parts.
I do agree with you Feejay, I would never put something like Slick 50 (50weight oil) in my engine because that stuff does turn into wax and clogs up galley holes in the head and can build up in the oil pump. I promise, the Lucas does no such thing. If you were to see and feel it with your fingers, I think you would agree.
HEMI TICK is in the valves. I think the reason is that the Valve guide clearance is to large from the factory.
