Adding ZDDP to Oil

You won't know me, but I've seen you at various MG gatherings over the years! One day I'd love to get out to Michigan!

No doubt you are aware of the problem being talked about, that the formula for modern oil is lacking various ingredients considered essential for our older cars? I am the original owner 1974.5 MGB GT (my only car/regular driver), and I have just had a new engine installed in her; I'm particularly anxious not to ruin it! I have heard various suggestions - add STP; add something called "Compcam"; use "Red Line" synthetic oil.......what are your thoughts?

Whenever you have time, I'd be very interested to know your opinion, please? Many thanks.

You SURE want to have enough ZDDP in your oil at startup! Where to find it? Red Line has enough; Castrol makes a racing oil with enough; or you can call David Anton at APT (or contact them through APT-FAST.com) as he sells excellent cams and must have this stuff on the shelf.

I am still uncertain as to the veracity of the original complaints and if they are as dire as some state, what the proper plan of attack is. My Castrol rep tells me that their racing oil is good.
