Will this subject every get ironed out for the masses? Get yourself some Delo 400 LE 15W40. NAPA's house brand 15W40 "diesel" oil, or Valvoline's 15W40 diesel oil is good. They are all CJ-4 with plenty of zinc (1300 plus ppm) for stock to mild builds. In fact, many of the racers run the 15W40 diesel oils. Plenty of zppd (zinc) for ya, at least 1300 ppm. The synthetic diesel (also called heavy duty engine oil HDEO) has more zinc than the dino oils. Shell Rotella T 15W40 has just under 1200 ppm zinc. Shell Rotella T 5W40 synthetic has over 1300 ppm zinc. Do a search. This subject has been covered real well.

I agree. I use Delo 15w40 in everything I have. Not only that, I get a discount from my dad's construction business if I go to the diesil fuel stations.
One of my 318s now has 6000 miles since rebuild with a Comp XE268 cam. Can I discontinue use of the Comp break in lube and just use the oil? If I could save $13 dollars an oil change and still be safe?
Dont mean to hijack, but maybe it could help others out if they search the same thing in the future.

i've always thought you used 30w on the 1st start up and 20min break in.
With the lack of zddp (zinc)in today's oils, it is not wise with the new flat tappet performance cams out on the market. You need to use some kind of a break in lube that adds those addititives, such as GM EOS, COMP cams break in lube, Hughes engines lube in conjunction with a good oil. Without the sufficient level of zinc in the oil during break in, the proper cam wear pattern may not be achieved, thus leading to premature cam lobe failure.
Stock motors with NOS cams may not be as vulnerable to this as new aftermarket cams subject to high spring pressure are.
