Brad Penn
Grades: 0W-30, 10W-30, 10W-40 , 15W-40, 20W-50
Claim: In addition to our unique base oil cut, increased concentration of “zinc” (zinc dialkyldithiophosphate a.k.a. ZDDP) provides outstanding anti-wear/anti-scuffing protection for engines employing either ‘flat tappet’ or roller cams. BRAD PENN® Penn Grade 1® High Performance Oils have been evaluated by a number of premiere camshaft manufacturers with tremendous success. Many are now recommending our Penn Grade 1® High Performance Oils to provide outstanding protection for their ‘flat tappet’ or roller cams.

Castrol Syntec 20W-50
Grades: 20W50
Claim: "Engineered to increase wear protection for classic cars with flat tappet camshafts"
Verification: Email from Castrol 12/9/09: Current Syntec 20W-50 (for classic cars) is actually a modern premium quality API SM product that has been Zinc boosted to Zinc levels that are reminiscent of levels from historic API categories such as SG when flat tappet cams with high spring loads were common in the fleet. For reference, note that the API SM category has the most rigorous passenger car engine oil (PCO) test performance requirements in the history of the API PCO categories. The level of Zinc in the new Syntec 20W-50 is a minimum of 1200 ppm, which will provide excellent anti-wear protection for the cam and lifters in a flat-tappet cam engine.

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.
CompCams Break-in Oil
Joe Gibbs Break-in Oil
Royal Purple Break-In Oil
GM Engine Oil Suppliment (EOS)
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 of API 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 loads that 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 - not what is found in a performance engine. 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 ILSAC GF-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.
"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 oil. The International Lubricants Standards Approval Committee (ILSAC) CJ-4 (diesel) specification states a maximum of 1200 ppm phosphorus, and oil analysis typically shows significantly less. Also, the additive package is significantly different than gasoline oils. Please see the note at the top of this sticky and do a search - you'll find no end of threads discussing this; evaluate for yourself.
Note 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.
