So I have been considering adding some ZDDP to my older vehicles with flat tappets. These are an '87 Buick Grand National (3.8Turbo), 1966 Cadillac Deville (429V8) and 1932 Ford street rod with a '57 Thunderbird 312V8.
Any recommendations on brands or would a better idea be just run something like a Valvoline VR1 motor oil? I don't want to run a pure racing oil because I want all the additives to protect the engine in street use.
