<DIV>Not sure if anyone will reply because this subject comes up on every car
site all the time..., or everyone will chime in with their opinions. Long
term I’d say to switch to a 302 roller cam engine or adapt the 260-289 to roller
cam. Short term..., I’d say to investigate if the current ZDDP additives
are actually beneficial. Unfortunately my investigation has show that
there are contrary opinions. Mild cams and weakened valve springs might
not be such a bad thing under the circumstances.</DIV>

<P class=MsoNormal>Have I been using the wrong motor oil all these years?
Just read several articles on the net stating that modern motor oils that do not
contain enough ZDDP (zinc) and can cause damage to the cam. True or
False?<o:p></o:p></P>
<P class=MsoNormal>What oil (weights and or brands) should be used in our older
engines, or should we use an additive to increase the ZDDP?<o:p></o:p></P>

<P class=MsoNormal>Thanks<o:p></o:p></P>
