[Healeys] Oil Warning again with still greater peril!

[Awgertoo at aol.com]

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.
