You can look up the MSDS for any motor oil using the oil's site. Most (not all) have this data available. For instance, Mobil 1 Extended Performance 15W-50

SARA (313) TOXIC RELEASE INVENTORY:

The MSDS is useless because it does not spec the zinc/phos in ppm figures that we use for comparison and oil ratings labeling.

I'm not so sure about useless, and nowhere did I state this is the only source for this information. If I really wanted to know I would send it off to the lab for analysis. There are, and have been, plenty of folks who have used and recommend specific oils for specific uses, many of them reputable and well known. Known oils with a specified amount, and oils that have similar and like amounts as per their msds, are more likely than not to be at or near those same levels as the known with a given ppm. I am not assuming anything. I have noticed though your push of a particular product.

But wait, I know... ZDDPplus has what you need.

However, many motor oils are adequate for use with solid and hyd flat tappet cams, not just the additive zddpplus. I suggest further investigation on your part.

Gentlemen;(and all others too), I believe I MAY have found an inexpensive oil that will work well for break-in. WalMart sells a brand called ACCEL in a formulation for API service grade SF for "1988 and earlier model years". I purchased and researched the MSDS from the manufacturer Warren Distribution/Warren Petroleum Products of Omaha,Ne. and found ZDDP level is rated at 1-5% which would translate as being between 10,000 - 50,000 PPM. The downside being that the detergent levels are much lower for SE/SF rated oils, but if you're gonna run it 45 minutes for cam break-in then drain it out, is that really going to present an issue anyway? I have idea to try that + 1 bottle STP oil additive for break-in. At around $1.90/qt it might prove to be a lot more cost friendly than the expensive racing oils. What do the rest of you all think? -Jim

We have been using the http://www.cen-pe-co.com/ 20/50 for cam break ins as it has 2300 PPM if zinc and is high in phosephate and for most of our street performance engines are running the 15/40 CENPECO which has 1582 PPM of zinc and is high in phosephate.

Once our circle track engines our broke in we have our customers go to the AMSOIL 20/50 as some of our flat tappet engines run 180 at the seat and 430 over the nose.

If you go by the 4 ball wear test their oil is hard to beat and some of their oils are rated at 35000 miles and Mobil is 15000 miles and I see Mobil never tests against AMASOIL I wonder why. Amsoil is the pioneer in synthetics.

Years ago Mobil had a dam good oil but over the years they have changed their formular to many times.

Here are some good links to look over.
