[DeTomaso] ZDDP heads up about MOBIL 1

[Charles Engles]

Dear Robert,


                I have not read the referenced article, but I would think 
that it refers to the plain vanilla 5W-30 and not the racy 15W-50 race oil 
that is *supposed* to have a good dose of ZDDP?    Is that right?   The 
Mobil-1 race oil was not specifically tested and *it* (if as advertised) may 
be good?

                              More zinc phosphate for everybody!, Chuck 
Engles

In talking with various folks trying to gather more fact and fiction I ran 
into the following as regards Mobil 1 oil.
I have Ashland's (Valvoline) Technical Director Thomas R Smith's paper in 
front of me. where in it states, "Mobil 1 5W-30 does not meet minimum API SM 
or ILSAC GF-4 specifications becasue of its inferior performance in the 
Sequence IVA wear test."

ILSAC=International Lubricants Standardization and Approval Committee
API=American Petroleum Institute
Each set standards and certify oil blends. It is speculated that were it any 
other than Exxon Mobile the "splash" would be MUCH greater. The facts stand 
and Ex.Mobile have not to date done anything but challenge Valvoline for 
proof. That (the proof) went public 4 months ago.
API SM (ILSAC GF-4) have minimal ZDDP which appears insufficient for freshly 
built flat cam engines.
The apparent proven allegation that Mobile 1 fails to meet its own 
specification may be of a concern to DeTo owners.
