Andrew, Yes, you are right, the Hotrod oil you can drive on and is specifically formulated for that purpose. It gives the highest metal to metal protection for flat tappet, push-rod style engines while coating the parts to keep them from rusting while it sits. It is not good for cars with catalytic converters though as the high zinc and phosphorous content will reduce the life of the converter. They also have a cam lube in the form of a kind of past that is real nice for applying to the cam lobes, journals and gears that dissolves quickly after initial start up to mix with the oil. Good stuff for those areas. This is one of the hottest oils used a in NASCAR. Nick Alfano Performance 4849-76 st.
