The answers to this long asked question would circle the globe many times if typed end to end on a sheet of paper. As many of us are concerned about how long a F/2F will last I thought it was important to point out the fact that there are not many store bought oils available that contain levels of anti wear additives and friction modifiers which were originally specified for these engines. ZDDP as it is commonly referred to was removed from commercially available motor oils a few years ago as they apparently reduce the catalytic converters ability to reduce emissions.
These newer oils have been cited as causing excessive wear, lifter, and camshaft failure in older flat tappet style engines.
I have been using a Pennzoil 25W50 Racing Oil in all of my older vehicles along with one bottle of Comp Cams Assembly Lube to try to prevent the loss of a camshaft.
Newer roller camshaft motors don't seem to be affected by the lack of ZDDP in the newer oils.
What type of oils/additives are others using in F/2F egines?
