We sell Zinc additives at work.
There are far more new vehicles out there that do NOT need the Zinc to clog up thier cats then vehicles that have no cats and still use flat tappets.
This reminds me...I wonder if the poor performance in the 72 is due to the fact that its a flat tappet engine, and Ive been running modern oil through it. Perhaps the cam shaft is a bit smoother then when it came from the factory?
Guess that means yet another heads/cam/intake plan for yet another Camaro.
