I've just been on a thread about engine oils where many opinions were given and I was told at one point i was wrong about a fact i provided (literally stated the GM manual), but when asked why i was wrong, was not given any reason why. There were a lot of recommendations for a fellow board member on here to use a specific racing oil, without any reason and without knowing how his car was being used. It drove me to continue my research into oil facts and thought i would share this handy article i came across:
( i found this later, still good info:

Many thanks to everyone that posted oil information across the Forum and on this thread!
Summary: If you use a flat-tappet cam run an oil from this list or another oil you're sure has at least 1000 ppm ZDDP. No additives (other than for break-in), no diesel oils, no racing oils and no miracle cures - just the right oil. For break-in run any oil from the list plus a break-in additive or use one of the specialized break-in oils.
If all you want is a good oil choice, you can skip the rest of the background here and just scroll down to the list of oils. More technical background is at the bottom of this post for those that are interested.

Regarding "wear testing" by 540 RAT: Forum member 540 RAT has done extensive self-testing of oils with his own equipment and methodology. Although positioned as "wear testing", it measures only a single aspect - film strength - and discounts the need for ZDDP for flat-tappet cams. This is counter to guidance from all cam and oil manufacturers. Read and review for yourself:

Engine Break-In Oils/Additives
Brad Penn Break-in Oil
"The Brad Penn Penn Grade 1 Break-In oil is designed specifically with a lower level of ZDDP and other select additive components as a Break-In oil. Since break in is a wearing process high levels of an anti-wear additive may be counterproductive. The type of ZDDP used in this oil is also more suitable for break in applications." Taken from the Brad Penn website; the concept of less ZDDP for initial break-in is counter to offerings by other vendors and cam vendor guidance. Evaluate for yourself.
AMSOIL Break-in Oil
CompCams Break-in Oil
Joe Gibbs Break-in Oil
Lucas High Zinc Engine Break-In Oil
Royal Purple Break-In Oil
GM Engine Oil Suppliment (EOS) (additive)
Technical Background
ZDDP (Zinc Dialkyl-Dithio-Phosphate, "zinc" or"zink") is an anti-wear oil additive that contains roughly equal amounts of zinc (Zn) and phosphorus (P) and is particuarly critical for correct lubrication of flat-tappet camshafts. The amount of ZDDP has decreased over time with the broad adoption of roller-tappet cams and the negative impact ZDDP has on catalytic converters.
Standards for engine oil are set by the American Petroleum Institute (API) and the International Lubricants Standards Approval Committee (ILSAC). Prior to 1988 API SF specified a minimum of 1500 PPM P. In 1993 API SG reduced reduced the minimum to 1200 PPM, and it was reduced again to 1000 PPM with the SL specification. A broad wave of flat-tappet camshaft failures started in 2004 following introduction ofAPI SM and ILSAC GF-4 oil specifications which set a maximum of 800 PPM and a minimum of 600 PPM P for grades SAE 0W-20, SAE 5W-20, SAE 0W-30, SAE 5W-30 and SAE 10W-30. Initially blamed on poor cam quality control, it was quickly determined that it was in fact the reduction of ZDDP combined with more agressive cam profiles and associated higher spring loadsthat were the root cause. Testing that showed the new oils would still have acceptable ZDDP for flat-tappet cams was done with very mild cam profiles and very low spring pressures. This is not what is found in even a mild performance engine, but may work - or at least appear to work- in older stock-type engines that don't see hard driving, have mild cams and tired valve springs or just see very few road miles - hence the perspective for some that ZDDP levels are not a genuine issue. Each needs toassess the risks and costs and determine their best choice. Note that as an additive ZDDP loses potency over time, losing approximately 1/2 of it's effectivness at approximately 6,000 miles. The latest API SN and ILSACGF-5 specifications do not change the maximum/minimum ppm ZDDP.
API/ILSAC Oil Specifications
From these events, specifications and timeline I propose that:
Flat-tappet cam failures started with the reduction of ZDDP < 1000 PPM.
Based on this, 1000 PPM ZDDP is the minimum required level.
Levels of 1200-1400 ppm ZDDP may be required for more extreme cams. What level defines too much ZDDP is unclear, but for street use more than around 1400 PPM is likely not appropriate.
Oil change intervals should be no more than ~3,000 miles with dino oil, ~6,000 with synthetic.
Any oil marked API SM/SN, ILSAC GF-4/5 or ILSAC CJ-5 in grades SAE 0W-20, SAE 5W-20, SAE 0W-30, SAE 5W-30 and SAE 10W-30 cannot have sufficient ZDDP.
The oils listed above claim to contain >=1000 PPM ZDDP and/or claim to be specifically formulated for flat-tappet cams. Note that the list is specific for product and grades - often a different product or grade by the same manufacturer won't have the same level of ZDDP.Where there is verification, it's linked. I am not making recommendations and I have no axe to grind - if there need to be changes, post the information for review.
Specifically not included in the list are:
Racing oils that are only available in single-weight. Additionally, generally racing oils aren't a good selection for the street, as they're not designed for extended change intervals or street start-and-stop cycles.
"ZDDP" additives (other than those specifically for engine break-in) as these are not recommended by any oil manufacturer.
Oils not readily retail-available.
Diesel oils, as noted at the top of the sticky.
Regarding switching from mineral to synthetic
There's a lot of feedback that making this switch causes engines to develop leaks. This can be the case, but it's important to understand why. Synthetic oil is more solvent than mineral oil, meaning that it can clean and remove deposits left by mineral oils - and expose worn or damaged oil seals. If your engine currently uses more than about 1 quart every 1,000 miles or is already "leaky", you may experience leaks (or worse leaks) by switching. Note that this solvency is a good thing; this is exactly what keeps an engine far cleaner when running synthetic.
Oil Analysis Companies
BlackstoneLabs
Oil Analysis Labs, Inc.
Note that it is CRITICAL that the oil be well-agitated before pouring a sample! Also note that the accuracty of "Virgin Oil Analysis" has been called into question based on a number of inconsistent results; see this link and associated links to evaluate for yourself. Brad Penn also notes disparity in these results.

Viscosity (cSt at 100*C) = 11.5 (cSt range for SAE 30 is 9.3 to 12.4) And cSt (centistokes) in general terms, represents an oil’s thickness.
***NOTE: The zinc and phosphorus anti-wear levels of all oil in this list, are elemental values, which are NOT the same as ZDDP values. Earlier oil industry testing found that above .14% or 1,400 ppm, ZDDP INCREASED long term wear, even though break-in wear was reduced. And it was also found that .20% or 2,000 ppm ZDDP started attacking the grain boundaries in the iron, resulting in camshaft spalling.
But the correlation between elemental values and ZDDP values varies by motor oil manufacturer, and they do NOT publish their ZDDP values. That makes it difficult to impossible for the consumer to know how elemental and ZDDP values actually compare for any particular oil. However, these elemental values are so extremely high here, that this oil really is only suited for short life dedicated racing engines, as the name implies. Using zinc/phos levels this high in other engines could be cause for concern, since excessively high levels, used for more than just break-in, can “cause” engine damage rather than “prevent” it.
This by Brad Penn:
There is such a thing as too much ZDDP.
ZDDP is surface aggressive, and too much can be a detriment.
ZDDP fights for the surface, blocking other additive performance.
Acids generated due to excessive ZDDP contact will “tie-up” detergents thus encouraging corrosive wear.
ZDDP effectiveness plateaus, more does NOT translate into more protection. Only so much is utilized.
We don’t need to saturate our oil with ZDDP.

Joe Gibbs 10W30 XP3 Racing Oil (lab tested 2011)
NOTE: Some of the numbers here were so unusual and unexpected, that I had the lab re-test the oil sample on another day, after other oil tests showed normal results, just to ensure that the original test was valid. And the re –test came back with the exact same numbers. So, the numbers here, are what they are. But we know this line of oil works incredibly well. Because it was developed for, and is used by, winning Sprint Cup NASCAR teams.

The detergent and TBN levels are so very low here, that this oil should most likely be changed after every outing, before those components are totally exhausted.
This oil line is one of the leading oils used in NASCAR Sprint Cup endurance engines, yet it has very low levels of zinc/phos, about the same as modern API SN oils. So, this is one example of a textbook case showing that you cannot really depend on elemental zinc/phos numbers alone, to predict how well an oil can protect against wear in high HP, high RPM engines. If you looked at the zinc/phos levels alone, like so many folks do, you’d think this oil should only be used in granny’s late model grocery getter.
This is something that the Royal Purple folks have said all along as well. Because their proprietary “Synerlec” additive is their primary extreme pressure additive, and their zinc/phos levels are only icing on the cake and do not need to be as high as it does with other oils.
The only way to really know how oils compare to each other with regard to preventing metal to metal contact, is to perform lab testing (quickest and most controlled method, particularly when testing a large number of oils) or real world on the road or on the track testing (time consuming, not well controlled, and perhaps impractical if a lot of oils are involved). This way you can test the whole additive package along with its base oil, to see how the overall product actually works. Simply looking at an oil lab test printout, is not enough information to always give you the right answer.
It’s the same thing with a new engine. You don’t just look at its build sheet to really see how well it will perform. You test it on the dyno and/or on the track (or road), to see the real deal.
So, with all that in mind, I’ve ordered an oil wear tester. And in the coming months, I’ll be performing impartial testing of all the oils on this list, and maybe a few others, to see how they rank against each other. I don’t really care which one wins or how they rank. I just want to “KNOW” which one wins and how they rank, so that I can make a better informed decision as to which oil I want to run in my own motors. I have no problem switching brands if the test results show the need to do so. Once I put all that data together, I’ll post the results for anyone interested in seeing it.

The detergent, anti-wear and TBN components of this Extended Performance oil are either about average or below average for typical API SN oils (even though some of the components are a little higher than in its standard Mobil 1 counterpart). TBN eventually becomes depleted as miles accumulate on oil in service. That’s “one” of the primary reasons for changing oil in the first place, to replenish the exhausted additive package. And it’s not unusual to see TBN values drop by as much as 60% from the original value, in only 5,000 miles. And with this oil starting out with a fairly low TBN value to begin with, it would seem very unlikely it could ever go a whopping 15,000 miles without having the TBN totally depleted well before reaching that 15,000 mile mark. So, this extended mileage claim appears to be only an unsupported marketing gimmick.
But, for those interested in long drain intervals, I’d suggest sending in a sample of this oil and having it lab tested at about the half way mark of 7,500 miles to see how much, if any, TBN remains. But, of course motor oil is typically already dark, dirty, contaminated and in need of changing by 5,000 miles anyway.
