For those of you who are just getting over or still questioning the
authenticity of the whole ZDDP scare now there is something new to be concerned
about:
According to an article in the May issue of "Victory Lane", a magazine
addressed to the Vintage Racing community which is heavily populated with
flat-tappet engines, API SN-ILSAC GF 5 oil will be going on the shelves in
October, 2010 and will contain "viscosity modifiers" that will "help thin oil
act thicker" in order to improve EPA-mandated gas mileage averages.
The article states that this modification is accomplished by the addition
of polymers and detergents that work in "low stress" situations but can be
sheared in "high stress" use and that the polymers are designed to replace
those old standbys of zinc, phosphorus and sulphur that were used to protect
our engines.
The article was written by Lake Speed Jr.of Joe Gibbs Oil so you may say
that he does have a dog in the fight as JGO sells racing oils, etc. that are
designed to deal with these issues, so please yell at Lake, not me.
Let the flaming begin---Michael Oritt
