Mobil 1 Claims 15w50 has 1200 ppm Phosphorus
From the Mobil 1 website "Ask Mobil" section:
Question:
Has Zinc Been Removed from Motor Oils?
I am having thrust bearing failure in a 4.6 modified performance engine. This is a street/strip engine. Many of my friends are having the same problem. I think it s the result of the removal of zinc from the oil. I was told by two separate racing engine builders that the EPA ordered the removal of the zinc from over-the-counter motor oil. I use Mobil 1 5W-20. Is this true and do you think a zinc additive might help?

Answer:
The active ingredient that you are talking about is phosphorus which is added thru a component called ZDDP. For products that meet the new ILSAC GF-4 specification the phosphorus levels for the oil must be less than 800 ppm phosphorus. The ILSAC level for phosphorus has been reduced to protect the catalytic converter and other emission protection equipment. The engine manufacturers are confident that this level of phosphorus will protect both new and older engines. However, there are Mobil 1 products which have a higher level of phosphorus (phos) and can be used in engines in racing or high performance applications; see the attached table.
The table link is below:

By their numbers, no ZDDP additives or mixing Mobil 1 V-Twin 20W50 would be required.
Here we go again!!!! ;^)

And it's available at my local Kragen :-)
Here's the description from their page:
You've never seen an oil like this before. Mobil 1® Extended Performance is a new high-endurance motor oil with 36 percent more anti-wear additives and 37 percent more cleaning agents than current Mobil 1 formulations. It is a fully synthetic formulation that helps extend engine life, reduce oil breakdown and minimize engine wear -- all while helping to keep your engine clean. Improvements that add up to exceptional protection for 15,000 miles. Guaranteed.
* Guaranteed performance and protection for up to 15,000 miles.
* Mobil 1 technology designed for today's longer service intervals.
* Proprietary formulation with 50 percent more SuperSyn helps keep engines running like new.
* Helps extend engine life by reducing wear and oil breakdown.
* Mobil 1 technology has been field tested over the last 20 years in the most severe driving conditions.
* Suitable for cars, vans and light trucks.

Steve - exactly. A recent thread titled "Oil for my '79 SC" covered some of this topic. I don't know how to link it to here, but it's on page 6 of this forum as of this morning. In addition to Steve's comment, I think that it's equally important to know that ILSAC GF4 is not necessarily a good thing for our early engines - it's been reported that the viscosity can become too thin. If someone who knows how to link the above thread it might simplify this thread. Thank you.
