It is important to note that these "racing oils" with all that extra
phosphorus and zinc are not recommended for street applications.  The first
thing these oils will take out is the catalytic converter and the O2 sensor.

The Mobil 1 15w-50 is still a relatively high zinc oil.

Mobil 1 0W-50 is a racing oil with about twice the amounts of phosphorous
and zinc as their street oils.  See the Mobil 1 Product Guide:

In the following faq there is interesting information about using Mobil 1
oils other than automobile street oils in cars.
