[DeTomaso] Oil, re-hash

[Paul Timko]

You need to be careful which Mobil One product you buy.

As stated on the Mobil website, new regulations are forcing oil 
companies to reduce the levels of phosphorus in their oil.  Based on the 
PDF you linked in, the reduced ZDDP oils are marked GF-4.

The only Mobil One oils that contain 1200 ppm of ZDDP are those marked 
only with SM and not GF-4 (plus the racing oil and the V-twin oil which 
are 10W-40 and 20W-50).  Due to the regulation changes, I would expect 
that shortly you will not be able to go into your local Auto parts store 
and find Mobil One that is not labeled GF-4.
